Effect Factors of Soy Sauce Wastewater Treatment by Allure-type Wastewater Treatment Equipment

Allure-type wastewater treatment equipment is a typical anaerobic-aerobic treatment technology for soy sauce wastewater treatment. Chromaticity material is one of the factors affecting the treatment effect except salinity, nutrients, and dissolved oxygen. Part of COD comes from chromaticity material, too high chromaticity volume load inhibit metabolism of aerobic microorganisms, and resulting COD was not degraded in aerobic process.
