Shunt anti-stripping biological rotary disc sewage treatment device

Abstract

The invention discloses a shunt anti-stripping biological rotary disc sewage treatment device which structurally comprises a bracket, sewage inlets and outlets, biological rotary discs, a shell and arotating shaft. The interior of the shell is provided with the rotating shaft, and the shell is arranged on the bracket; two or more sewage inlets and outlets are arranged at both ends of the shell; the rotating shaft is provided with two or more biological rotary discs; each biological rotary disc is mainly composed of two or more discs. Mainly through a shunt structure and connecting columns, inthe process of driving water flow by disc rotation, the water flow entering the water flow discs is buffered, the impact of the water flow on a biofilm is slowed down, a V-shaped blocker is used forintercepting the separated biofilm, at the same time, the water flow is discharged from both sides to avoid the impact of the water flow on the connection parts between the discs and the rotating shaft and then avoid stripping off; the connection between each two discs is fixed by the connecting columns. The stability of the device is improved.

Description

Technical field [0001] The invention relates to the field of biological turntable treatment devices, in particular to a shunt and anti-dropping biological turntable sewage treatment device. Background technique [0002] The biological turntable is a biological membrane wastewater treatment technology. The biological disk can be attached to microorganisms with a long growth cycle and has strong impact load resistance. The biological turntable sewage treatment device is driven by a motor and driven by a reducer to drive the shaft according to the design It rotates at a fixed speed, which drives the bio-disk to rotate. However, the current processing device has the following problems: [0003] 1. Because of the growth of microbial colonies and the accumulation of colonies on the biological disc, the gravity of the disc will increase, which will increase the load of the disc, and the disc will easily fall off during the rotation; [0004] 2. The biological disc will rotate with the rota...

AI Technical Summary

Problems solved by technology

[0003] 1. Due to the growth of microbial colonies and the accumulation of bacterial colonies on biological discs, the gravity of the disc will increase, which will increase the load on the disc, and the disc will easily fall off during the rotation process;
