1. Odor: In the process of sewage treatment, the sewage treatment plant will produce a certain unpleasant smell, mainly from the sewage itself and the biological treatment process. This smell may have a certain impact on the air quality of surrounding communities.

2. Noise: In the process of sewage treatment, a certain degree of noise will be generated, mainly from the work of various treatment equipment. Long-term noise may affect the quality of life of the surrounding residents.

3. Solid waste: Solid waste, such as grid slag, gravel and sludge, will be generated during sewage treatment. The treatment and disposal of these wastes need reasonable planning and management, otherwise it may have an impact on the surrounding environment and residents.

4. Water environmental impact: If the sewage treatment plant is not operated properly, it may have an impact on the surrounding water environment, such as water pollution and river water quality deterioration.

Generally speaking, as long as the sewage treatment plant is planned and operated reasonably in strict accordance with the regulations, the impact on the surrounding communities will be controlled in a low range. At the same time, relevant departments also need to supervise the operation of sewage treatment plants to ensure that they meet the requirements of environmental protection, thus ensuring the quality of life of surrounding residents.
