Design principles

(1) Conscientiously implement the national guidelines and policies on environmental protection, and abide by relevant national regulations, norms and standards.

(2) The equipment selection should comprehensively consider performance and price factors, and the equipment is required to be high efficiency and energy saving, low noise, reliable operation, and simple maintenance and management.

(3) The principle of no secondary pollution, cleanliness and safe production.

Source of pollution

Silt treatment, sewage treatment, waste gas treatment

Processing technology

The sludge treatment system used in this project is mainly composed of a large particle material isolation system, a sedimentation separation system, a heavy metal passivation system, an odor removal system, a sludge-water separation system and a wastewater treatment system, etc.
