How to harness this polluted river?

Hello, mainly take the following measures to control polluted rivers:

Investigate and understand the types of river pollution, the distribution of pollution sources and the setting of sewage outlets, and treat the wastewater from industrial and mining enterprises along the river to ensure that the discharge standards are met. If it cannot be treated within a time limit, it shall be shut down and transferred.

Control non-point source pollution along the river (using pesticides and fertilizers), prohibit the discharge of domestic garbage and waste into the river, dredge the river, and pay special attention to key river sections (water intakes, landscape waters, etc.). ).

Protect the capacity of tributaries (if any) and catchment areas, ensure ecological flow, and enhance the dilution and purification capacity of rivers.

Greening along the river, planting trees and grass. Strengthen soil and water conservation and reduce soil erosion.

Construction of sewage treatment plant, laying sewage pipe network, and comprehensive utilization of production wastewater and domestic wastewater from enterprises and institutions along the line as much as possible after receiving and treating, so as to reduce emissions.

Establish a supervision mechanism to strengthen the monitoring and inspection of river water quality.
