Omnibearing vertical-flow sewage treatment device and method

Abstract

An embodiment of the invention relates to an omnibearing vertical-flow sewage treatment device and method. The treatment device comprises a conical settling base, three concentric barrels, namely an outer barrel, a diversion barrel and a clear water barrel, sleeve the conical settling base, the outer barrel is hermetically connected on the outer wall of the conical settling base, the bottom of thediversion barrel and the bottom of the clear water barrel are connected on the outer wall of the conical settling base in a clamped manner, the upper-portion wall of the outer barrel is provided witha sewage inlet and a clear water outlet, and an aeration component wound on the conical outer wall of the conical settling base is arranged in an annular cavity formed between the inner wall of the outer barrel and the outer wall of the diversion barrel. Sufficient mixing of active sludge and sewage is realized during aeration oxygen supply, sludge-water separation is realized efficiently and stably in a still water area, and power equipment like a backflow pump and a stirrer is not needed, so that energy consumption is saved, and system fault rate is reduced; the sewage treatment device is compact in layout, small in occupied area, free in site selection and good in sewage treatment effect.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to an omnidirectional vertical flow sewage treatment device and a treatment method thereof. Background technique [0002] With the rapid development of my country's economy, the discharge of sewage is also showing a growing trend. The sewage generated in the city is usually treated centrally through sewage treatment plants, but in the vast rural areas, the villagers live scattered and cannot be concentrated There is no centralized sewage treatment equipment for sewage treatment; on the other hand, the current situation in rural areas is that the kitchen, toilet and living room are not designed in one piece, and each has an independent area. Due to the above reasons, the current rural areas discharge sewage directly, which on the one hand causes a waste of resources, and also pollutes groundwater and nearby rivers. [0003] The above is obviously contrary to the call of "r...

AI Technical Summary

Problems solved by technology

Existing equipment for sewage treatment is usually large-scale sewage treatment equipment of the grid type, which not only occupies a large area, but also is expensive, consumes a lot of electricity, and has poor sewage treatment effect (low degradation rate)
