Application of self-cleaning filter in chemical wastewater treatment


The operation results show that the discharged sewage meets the national wastewater discharge standard. The water source treated by the automatic filter can be reused.

Petrochemical wastewater contains a large number of toxic and harmful substances with high concentration, various types, B / C value of 0.1-0.2 and complex components. There are nearly 40 kinds of pollutants in the system, and more than 20 kinds of pollutants that are difficult to biodegrade or non biodegradable. It is a typical refractory chemical wastewater. At the same time, the wastewater contains sulfide, amine, phenol Cyanide and other highly inhibitory toxic substances and their derivatives. The total amount of sewage is 34000 T / D, including 22000 T / D of chemical wastewater.

The full-automatic filter directly intercepts the impurities in the water by using the wedge wire filter screen, removes the suspended solids and particles in the water, reduces the turbidity, purifies the water quality, and reduces the generation of dirt, bacteria, algae and rust in the system, so as to purify the water quality and protect the normal operation of other equipment in the system.
