AI Technical Summary

Technical Problem

Existing technologies for treating milking parlor wastewater suffer from high costs, high sludge production, high energy consumption, and a significant risk of secondary pollution. Furthermore, biological agents have limited effectiveness and cannot efficiently improve water quality.

Method used

A microbial enhanced treatment system for milking parlor wastewater is adopted, which includes pretreatment, main treatment and advanced treatment systems. It uses a combination of various microbial enhancement agents and constructs a highly efficient wastewater treatment mode through sedimentation, anaerobic and aerobic reactions combined with ultraviolet disinfection.

Benefits of technology

It significantly improves the removal rate of COD and suspended solids, reduces treatment costs, reduces sludge production, reduces the use of chemical flocculants, reduces the risk of secondary pollution, and ensures that the water quality meets the requirements for aquaculture discharge and farmland irrigation water.
