AI Technical Summary

Technical Problem

Existing dams cannot replace dam body units during wastewater filtration, resulting in low filtration efficiency and easy accumulation of silt and sand in the dam body units, leading to hardening and clogging of the pores.

Method used

Design a dam with a biological purification structure, including a treatment pool, a platform, dam components and a filter frame. The filter frame is driven to rotate by a drive mechanism. The filter frame is filled with polypropylene suspended biological balls. Friction and collision prevent siltation. The filter frame can be replaced without stopping filtration.

Benefits of technology

This technology allows for filter frame replacement without stopping the filtration process during wastewater filtration, improving filtration efficiency. Furthermore, the friction and collision of polypropylene suspended biological balls prevent caking and blockage, maintaining a high-efficiency filtration effect.

Abstract

The present application relates to dam technical field, specifically disclose a kind of dam structure with biological purification structure, including treatment pond and platform being set on it, the drainage opening of the treatment pond is arc notch, and the radian angle of arc notch is 90 °, dam body assembly is arranged in the arc notch on the treatment pond, and dam body assembly is equally angularly distributed with mounting cavity, the inside of each mounting cavity is provided with sliding groove, and the corresponding slider is slidably connected on sliding groove, the slider is installed on filter frame, and filter frame is provided with filter screen fence, driving mechanism for driving dam body assembly rotation is installed on the treatment pond.The application can replace filter frame in the process of filtering wastewater, avoid the suspension of filtration caused by closing water valve, thereby help to improve the filtering efficiency, in addition, polypropylene suspended biological ball filled in filter frame will rub and collide with each other along with its rotation, thereby can scatter silt, prevent hardening and block hole.
