Time goes by and never stops. A period of work has ended. Looking back on this work, there must be many difficulties and hardships. It's time to write a work summary seriously. So is it really difficult to write a work summary? The following is a summary model essay of social practice that I collected for you. Welcome to share.
Summary of social practice 1 Through this social practice, I have learned a lot and deeply felt a person's enthusiasm in work. Because of this, I gradually understand a truth: to start my own business, I must redouble my efforts. With a person's persistence in his work, a firm belief will lead him to a perfect career.
During this period of internship, I realized the ups and downs in my work through my own efforts, and then I found myself the happiest. Because I'm still in the learning stage, I haven't really come into contact with my career, and I haven't really understood the hardships and difficulties of my work. Thinking about it, I still feel that I am still good now. Being able to study in such a good environment will lay a foundation for future work. However, I am ashamed of myself. I blame myself for failing to live up to my expectations. I don't cherish this good time and opportunity to study hard. I have nothing to do all day and I can't do anything at home. It was this social practice that gave me the opportunity to learn and unforgettable experience.
In the process of internship, I did everything I should do seriously and got a satisfactory answer sheet. I thought I had learned some basic knowledge, but I didn't know there was still much to learn until my internship. I still have a long way to go in the future I can't just be satisfied with the status quo, I must go forward bravely. People grow up in constant progress. Although there will be many bumps, there will always be a way to solve them. Being a man is not afraid of failure, and he is most afraid that he will never stand up after failure. You must believe in yourself, because I always say to myself, "Be brave and frustrated? What are you afraid of? There must be a rainbow after the storm. " Therefore, I have a firm belief, that is, to overcome the difficulties in growth and unswervingly move forward towards my own goals. I believe my tomorrow will be better!
Through this social practice, on the one hand, I have exercised my ability and grown up in practice; On the other hand, we have made our own contribution to society; However, there are also some problems in practice, such as lack of experience, immature handling of problems, and insufficient combination of book knowledge and practice. When we go back to school, we will cherish the time of studying at school, strive to master more knowledge, constantly practice and test our knowledge, and exercise our ability, so as to lay a solid foundation for better serving the society in the future.
The social practice of winter vacation is over, but the great influence brought by social practice is far from over. It enables us to go out of the campus, out of the classroom, into the society, onto the road of combining with practice, into the big classroom of society, see the world in practice, display our talents, increase our talents, hone our will and test ourselves. Half a month's social practice is very hard. Is it lucky? Or attachment? In retrospect, I realized that the original boredom was full of hope and bitterness was sweet.
As students, we take part in this winter vacation social practice activity with the desire to be close to and serve the society, hoping to get in touch with the society in advance and learn how to communicate with people, how to communicate with people, how to cooperate with people and so on.
At the beginning of the winter vacation, our team came to the construction site for social practice. In practice, we have known many leaders. The leaders were very kind and friendly, and they gave us a warm welcome. Our initial tension suddenly disappeared.
Subsequently, under the leadership of the technical staff of the project department, we ran around the construction site and immediately started a day's work. When we enter the construction site, we put on our helmets and gloves. When he reached the bottom of a three-story building, we squatted down and looked around at the reminder of the person in charge, but because the helmet on our head blocked the line of sight, we bumped into the steel pipe on the stairs several times and the helmet slammed. On the second floor, there were many steel pipes standing around between the upper and lower floors, and then we reached the last floor, and finally we couldn't be as careful as the first floor. There are several straight lines on the cement surface at the top. After the introduction of technicians, we understand the function of engraving. There are also steel bars with different lengths erected, and the person in charge said that it is because the bottom position is different.
After visiting the completion site, we had a labor experience. Although you can only do some physical work that seems to have no technical content, it is more complicated than expected. Each of us moved a board to the place where it was stacked. Those boards are multilayer boards used to cover the roof. They are very big. After walking for a while, the students were panting. Have a rest, drink some water and go on working. This time, two people lifted two boards. During this period, we changed several postures in order to save our strength, and the result became more and more tired. When we moved a pile of planks and saw a pile of planks as high as our shoulders neatly stacked together, the students felt a great sense of accomplishment.
It's just that time is too short, so we can only touch and absorb new things at a glance, but I have also learned a lot of knowledge that is not available in books through practice, which not only increases my knowledge, broadens my horizons, but also increases my practical ability and enriches my life experience, which will be my most precious wealth to the society.
Time always passes by your fingertips inadvertently! Looking back on the past day's rolling and crawling, I feel very lucky to participate in such a meaningful activity. Through this social practice, we understand the role of the team in the work, but also deeply feel the significance of unlimited knowledge and limited ability.
Ideas about activities:
We have paid our own sweat and gained knowledge that can't be learned in textbooks. I have realized my desire to be close to and serve the society, and I will never forget the short and fulfilling days I spent with my predecessors. Thank you for your concern and criticism!
Through this practice, we deeply feel that even a wall, a road and a tall building we usually see are built by the working people through hard work, and every place shines with the glorious sweat of the working people. We have experienced hard work, but what we have experienced is only the tip of the iceberg, thanks to the great working people. Compared with this, our efforts at school are nothing! Therefore, only by studying hard today, learning all the lessons and mastering all the skills can we contribute to the future social construction! This is my harvest.
From the practice, I can't bring back any exquisite technology, but I brought back perhaps the most precious and cherished harvest in my life. Many people who study at school say that they would rather go out to work than study at school; Only people in society would rather go back to school. We go to school and learn advanced scientific knowledge in order to enter the society in the future and contribute our strength. We should strive to master knowledge today and serve the society better tomorrow.
Summary of Social Practice Chapter III The one-week summer social practice activity of North China Electric Power University has now come to an end. Six students from Class 0802 of the Social Practice Investigation Team of the Institute of Environment also successfully completed their research and study in Hebei Datang International Wangtan Power Generation Co., Ltd., and gained a lot.
During five days, we visited and studied the production technology of the power plant, studied the key topics such as electrostatic precipitation technology, desulfurization technology, seawater desalination and water circulation technology, and understood and analyzed the economic benefits of the power plant. The specific process during the period is as follows:
On the first day of social practice, under the leadership of Wang Gong, we visited and studied all the production links of Wangtan Power Plant. During the period, Wang Gong gave us a patient explanation, including coal selection and rational utilization, turbine power generation, seawater desalination and seawater cooling circulation system, desulfurization system, dust removal system and so on. So that we can have a deeper understanding of these on the basis of the original work.
In our study tour, the most impressive thing is the dust-proof and dust-suppression net. Although there is no direct economic benefit, only a little loss is reduced, it just shows that Wangtan Power Plant can actively respond to the call of the country. We should not only look at the immediate problems, but also consider them in the long run, so as to conform to Scientific Outlook on Development. Spending huge sums of money to establish such a "non-economic benefit" system can bring long-term social benefits. This practice of Wangtan Power Plant is a wise choice, in line with the slogan of environmental protection and their own slogan-lighting up a better life with clean energy.
Followed by coal:
The power plant has a double-tilting unit, which is the only double-tilting unit in China and even in the world, and a train can be unloaded in a few cycles.
Considering the economic benefits, we should proceed from the overall situation, and not every link uses the best raw materials. For example, the coal used in power plants is basically inferior coal. This is the result of comprehensive consideration of cost and economic benefits.
On the second day of social practice, we started a special study-dust removal.
The staff first explained the relevant information of various data and drawings of dust removal to us, and then began to explain and learn on the spot.
Dust removal is the first topic. Flue gas contains a lot of dust, and the core of electrostatic precipitation is electrostatic precipitation equipment.
Each set of equipment consists of five electric fields, and each electric field has three important parts: cathode column, anode column and rapping. Its function is not only to remove dust by static electricity. The principle of electrostatic precipitation will not be repeated here. It is necessary to emphasize the following facilities-pipelines.
The flue gas from electrostatic dust removal should be pressurized through various pressurization valves to continue the next process. Among them, ash may block the pipeline, especially the No.3, No.4 and No.5 electric fields. When they are in winter, the ash in the pipeline is easily adsorbed to the pipeline after the low temperature becomes wet, causing pipeline blockage. At present, the treatment method is to add high pressure to remove ash, but it will wear the pipeline and cause certain losses. There is a lot of room for improvement here.
(Plate-and-frame filter press 2) In addition, I also know a little about desulfurization related processes and equipment. The power plant adopts limestone/gypsum wet treatment. Among them, the gypsum board produced by the plate-and-frame filter press is easy to stick to the plate frame, which is not conducive to automatic operation and needs manual treatment in the middle. At present, there is no good way to solve this problem.
On the third day of practice, we learned about the current situation of desulfurization project in Wangtan Power Plant from professionals concerned about desulfurization. People find that there are two main problems in factories today:
1. Because there is no heat exchanger in Wangtan Power Plant, the treated flue gas temperature is lower than the dew point (about 50 degrees Celsius), which is easy to form acid water and seriously corrode the flue, which is difficult to solve. At present, the technology of heat exchanger is immature, the equipment is easy to block, the maintenance amount is large and the maintenance cost is high. (Dingzhou Power Plant is equipped with this equipment)
2. Gypsum slurry is discharged from the chimney with flue gas. When it rains, there is "gypsum rain" in the factory, which spreads around with the smoke and produces yellow spots (gypsum) that are difficult to handle. Clothes, floors, glass, cars and other places are difficult to clean and need to be studied.
On the fourth day of practice, we learned the technology of seawater desalination and water recycling. Wangtan Power Plant successfully applied ultrafiltration to seawater desalination process, adopting full membrane method, which was the first in China. During this period, we also learned that even if the ph value is adjusted to 7-8, the desalinated seawater in the system will still be corrosive to the equipment, and the reason is not clear.
During our stay in the power plant, we studied hard, thought positively, mastered a lot of first-hand information and gained a lot. We have also established some optional topics for further study after the reunification.
