Rotary drum type wastewater processing device

Abstract

The invention discloses a rotary drum type wastewater processing device, which relates to the field of wastewater processing. The rotary drum type wastewater processing device comprises a reaction pool, wherein a rotary drum is arranged in the reaction pool; the rotary drum is fixed to a synchronizing wheel through a threaded hole; the reaction pool is provided with a power system; the power system drives the synchronizing wheel to rotate through a synchronizing belt; the middle of the rotary drum is provided with a long shaft; two sides of the rotary drum are respectively provided with a diskedge cover; each disk edge cover is provided with a groove; an inner side plate and an outer side plate are clamped in the groove. The rotary drum type wastewater processing device has a simple structure and is convenient in replacing scrap iron, the scrap iron is unlikely to harden, the filler is large, in addition, small holes in the outer side plate enable water and air to be conveyed into thefiller so as to accelerate the internal circulation of water, the aeration of reaction liquid is realized, and reaction is sufficient. In addition, at a definite revolving speed, the center of gravity of the entire rotary drum is near the central axis of the rotary drum in a filler consumption process, so that torque is smaller, and the provided energy is smaller, and therefore, energy consumption is lowered.

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
