AI Technical Summary

Technical Problem

In traditional wastewater treatment systems, sludge tends to accumulate and adhere to the lower end of the bar screen, causing blockage of the filter pores and affecting the efficiency of clean water flow and the normal operation of the system.

Method used

Design a low-carbon and energy-saving wastewater treatment system, which includes an anaerobic tank, an anoxic tank, an aerobic tank, a sedimentation tank, and a disinfection tank in the wastewater treatment tank. It is equipped with an intermittent pneumatic stirring structure and a sludge return and discharge structure. A bar screen and a cleaning structure are installed in the sedimentation tank. A photovoltaic panel drives a motor to drive a crank shaft, and a scraper removes sludge from the lower end of the bar screen. Combined with the agitation structure, the efficiency of clear water separation is improved.

Benefits of technology

It effectively prevents the bar screen from clogging, ensures the passage of clean water, improves sewage treatment efficiency, reduces maintenance difficulty and cost, and realizes green energy utilization.

Abstract

This application discloses a low-carbon, energy-saving wastewater treatment system, belonging to the field of wastewater treatment. The system includes a wastewater treatment tank, inside which are arranged anaerobic, anoxic, aerobic, sedimentation, and disinfection tanks along the wastewater flow direction. The sedimentation tank contains a grid plate for separating sludge from clean water. The sedimentation tank also includes a cleaning structure, comprising a crankshaft, bearing plates fitted at both ends of the crankshaft and fixedly connected to the grid plate, reciprocating grooves symmetrically formed on the crankshaft, mounting seats symmetrically fitted on the crankshaft and reciprocatingly connected to the reciprocating grooves, and scrapers mounted on the mounting seats. A drive motor for rotating the crankshaft is fixedly mounted on the wastewater treatment tank. Through the design of the cleaning structure, automatic cleaning of the sludge at the lower end of the grid plate is achieved, preventing sludge blockage and improving wastewater treatment efficiency and quality.
