1, the purpose of building sewage treatment plants is to treat wastewater to the discharge standard, minimize the pollution of the environment.
2, the necessity is mainly from the region, you can prove the necessity by discussing the impact of our production and domestic wastewater on the surrounding water environment without a wastewater treatment plant.
The location of the wastewater treatment plant should be in line with the outlet of wastewater, considering the need for phased construction of the entire drainage system, and subject to urban land use planning. Wastewater treatment plants, especially those with sludge treatment and dewatering equipment, have an impact on the environmental quality of the surrounding houses.
There should be appropriate isolation green belts. Developed computing technology has made the economic analysis of drainage system planning is becoming more and more perfect, the choice of sewage plant site is often solved at the same time with the planning of the whole system.

Treatment of wastewater sites:
In the city, also known as sewage treatment plant or sewage plant. Those located in plants are often called treatment stations, and when the effluent is placed in city drains, the treatment station is actually a pretreatment facility. The general objectives of wastewater treatment are to remove suspended solids and improve oxygen consumption (i.e., stabilize organic matter), and sometimes disinfection and further treatment.
Treatment of industrial wastewater focuses on the removal or transformation of oils, suspended solids, heavy metals, and organics that impede the operation of municipal wastewater plants or that have high residuals, as well as pH adjustment.
