Research of Biological Phase in Contact Oxidation Pond for Jeans Washing Wastewater Biochemical Treatment

Article Preview

Abstract:

The combined process of coagulation, hydrolytic acidification and contact oxidation was applied to treat the jeans washing wastewater, and the microorganism and COD concentration in the contact oxidation pond was monitored 40 consecutive days. the results showed that Vorticella, rotifers, arcellas, chironomid larvae, nematodes of the genus, changed in the number of the wastewater treatment had obvious indicating effect, activated sludge on the chromaticity of grain had obvious effect of adsorption, and flocculation particle morphological changes could also play a role in indicating.
