Industrial pollution refers to the violation of the natural environment by industrial enterprises in the production process, including human beings. Pollution is mainly caused by "three wastes" (waste water, waste gas and waste residue) and various noises in production, which can be divided into waste water pollution, waste gas pollution, waste residue pollution and noise pollution.

Harm of industrial pollution. First, the discharge of a large number of untreated water, gas, slag and other harmful wastes in industrial production will seriously destroy the agricultural ecological balance and natural resources and cause great harm to the development of agricultural production; Second, the industrial "three wastes" are also very harmful to industrial production itself. Toxic pollutants will corrode pipelines, damage equipment and affect the service life of factories. Third, environmental pollution and public hazards are rampant, which directly endanger the health of the broad masses of the people; Some pollution is not easy to find, and the harm caused is already very serious.
