Establish regional small-scale sewage treatment plants
View：0 Add Time：2025-07-05
For places where factories are concentrated, it is not necessary to apply the principle of "whoever pollutes, controls". Instead, it is necessary to strengthen the connections between various enterprises, coordinate and consider pollution control measures. If necessary and possible, the wastewater from each factory can be centrally treated, and a unified sewage treatment plant can be established to implement the "whoever pollutes, pays" control method. Because the quality of wastewater varies from factory to factory due to different products. For example, some factories have acidic wastewater while others have alkaline wastewater. Treating them together can reduce the cost of neutralizing agents; Some factories discharge high salt and low COD wastewater, while others have high concentration and easily biodegradable wastewater. If treated separately, they are difficult to treat. However, if treated together for biochemical treatment, the improvement of water quality conditions can not only reduce the difficulty of wastewater treatment, but also improve treatment efficiency.
