A drum type wastewater treatment device

Abstract

The invention discloses a rotary drum type wastewater treatment device, which relates to the field of wastewater treatment, and comprises a reaction pool. A rotary drum is arranged in the reaction pool, and the rotary drum is fixed with a synchronous wheel through a threaded hole. There is a power system, and the power system drives the synchronous wheel to rotate through the synchronous belt; there is a long shaft in the middle of the drum, and the sides of the drum are disc side covers, and the disc side covers have grooves , the inner board and the outer board are clamped in the groove. The invention not only has a simple structure, is convenient to replace iron filings, iron filings are not easy to harden, and the packing is relatively large, but also the small holes on the outer plate send water and air into the packing, which promotes the internal circulation of water and realizes the aeration of the reaction liquid. Make the reaction more sufficient, and under the condition of constant speed, the center of gravity of the whole drum is near the central axis of the drum during the process of filler consumption, so the smaller the torque, the smaller the energy provided, thus reducing the energy consumption.

Description

technical field [0001] The invention relates to a sewage treatment device, especially a device suitable for the treatment of heavy metal ion waste water, in particular to a drum type waste water treatment device. Background technique [0002] With the rapid development of industry and agriculture, environmental problems have increasingly become the focus of human attention, and the country has paid more and more attention to the improvement of the environment. Among these environmental pollution, water environment problems have become the focus of people's attention. Among them, heavy metal ions cause The problem of water pollution is particularly prominent. Because heavy metals have the characteristics of long duration, high toxicity, bioaccumulation, and refractory degradation, once heavy metal ions enter the water body, they will accumulate in animals and plants through bioaccumulation, and then enter the human body through the food chain. irreversible harm to health. ...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the disadvantages of serious energy consumption, inconvenient filler replacement and no aeration problems in the prior art, a new type of air filter is provided that not only has a simple structure, is convenient to replace iron filings, is not easy to harden the iron filings, and has relatively large fillers. The small holes on the plate send water and air into the filler, which promotes the internal circulation of water, realizes the aeration of the reaction liquid, and makes the reaction more complete. The center of gravity is near the central axis of the drum, so the smaller the torque, the smaller the energy provided, thus reducing the energy consumption of the drum-type wastewater treatment device
