Biological Bacteria Enzyme for Colored Sewage Treatment

1. Colored sewage content

Light yellow sewage - the iron content in the water has exceeded the standard;

Black sewage - the pollution of manganese ions is serious;

off-white sewage - with a lot of humus and clay particles;

Grass green sewage - contains chlorine sulfide;

Light blue-green sewage - containing ferrous oxide and waste water.

2. Reasons for the black color of electroplating wastewater after treatment

If polyferric sulfate is added during the chemical coagulation process, the iron salt reacts with the sulfide in the wastewater to form iron sulfide, which will cause the effluent to turn black.

Whether it is electroplating wastewater or other industrial wastewater, there are several indicators that exceed the standard and need to be treated, mainly including ammonia nitrogen, cod, phosphorus, and heavy metal ions.

For these different indicators, you can choose to use biological powder without pollution.
