AI Technical Summary

Technical Problem

In the existing sewage treatment process, the A2/O process has a large capacity, high floor area and construction cost, and a large return volume of sludge, resulting in low sewage purification efficiency within the unit range. At the same time, the existing magnetic coagulant treatment devices have high cost in preparing magnetic coagulant, and the magnetic coagulation effect is not good for suspended substances with small particles and low density. A large amount of magnetic coagulant and energy are required to be invested when treating large-scale wastewater.

Method used

A magnetic coagulation sewage treatment system is designed, including a magnetic coagulation sedimentation tank, an improved A2/0 tank, an adjustment tank, a cyclone sand sedimentation tank, a coarse grid water inlet tank and a fine grid filter tank, etc. The sediment precipitation efficiency is improved through a multi-chamber stirring and magnetic separation system, and the water quality is improved through a water purification filter mechanism composed of inclined pipe filler and a movable filter plate.

Benefits of technology

It achieves rapid sedimentation of waste, improves sewage treatment efficiency, reduces land occupation and construction costs, reduces the use of magnetic coagulant, improves water quality, and solves the problem of low water treatment efficiency of improved A2/0 ponds.
