AI Technical Summary

Technical Problem

Existing municipal sewage pipe network sewage treatment and purification integrated devices have poor treatment effects when faced with high-concentration organic wastewater and saline wastewater, and the amount of residual sludge after sewage treatment is large.

Method used

The system employs a layered structure of aerobic granular sludge, treating wastewater through aerobic oxidation in the outer layer and anoxic denitrification in the inner layer. Combined with anaerobic pretreatment and sludge recirculation flow control, a wastewater circulation is formed to promote the formation of aerobic granular sludge and control sludge concentration.

Benefits of technology

It achieves efficient degradation of organic matter, reduces the amount of residual sludge, and is suitable for treating high-concentration organic wastewater and saline wastewater, significantly reducing sludge concentration and improving treatment efficiency.
