AI Technical Summary

Technical Problem

Existing water purification devices require a large sedimentation tank to accumulate sufficient fecal wastewater before they can operate, causing the devices to shut down during this period, thus reducing their efficiency.

Method used

A pretreatment mechanism and auxiliary unit, including a pusher plate, a water pumping channel, and a water pump, are set below the screw extruder to directly treat the wastewater after the feces are dewatered. The pusher plate and water pumping channel avoid floating objects and sediments, and directly transport the relatively clean wastewater to the water purification device, reducing the number of pretreatment steps.

Benefits of technology

It improves the working efficiency of water purification equipment, prevents secondary pollution of water bodies by sludge, increases sludge disposal efficiency, reduces pretreatment steps, and improves overall sewage treatment efficiency.
