A low-pollution water treatment device and treatment method thereof

Abstract

The invention discloses a low-pollution water treatment device and a treatment method thereof. The treatment device comprises an integrated pool body, and the pool body is sequentially separated into a first filter pool, a photocatalytic chamber and a second filter pool by a partition wall; the first The inside of the filter tank and the second filter tank are separated into several layers of filter material layers by a screen; a photocatalytic component is arranged inside the photocatalytic chamber. The present invention can increase the filtration efficiency and stability between low-pollution water and the graded filter material layer on the basis of reducing the floor area of ​​the device, utilize the special filter material layer structure design to slow down the impact of the water load of the device, and effectively improve the distribution efficiency. The uniformity of the water guarantees the maximum biological contact reaction between the filter material layer and the sewage, and slows down the clogging during the filtration process; under the synergistic effect of the photocatalytic chamber, the enhanced sewage achieves deep and stable removal of low pollution in the second filter tank Organic matter and ammonia nitrogen in the water greatly improve the treatment efficiency of low-pollution water.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a low-pollution water treatment device and a treatment method thereof. Background technique [0002] In recent years, my country's economy has developed rapidly, and various types of water consumption have increased significantly. As a result, a large amount of low-pollution water has been produced in people's production and life. Low-pollution water includes sewage treatment plant tail water, initial rainwater in villages and towns, and discharge water after large-scale breeding , rural domestic sewage, agricultural runoff water, etc. [0003] At present, this low-pollution water is directly discharged into rivers and lakes except for greening and atmospheric dust spraying. The surface water environment is greatly affected, and there is an urgent need for effective and advanced treatment of low-pollution water. Due to the combination of biological contact oxidation and ...

AI Technical Summary

Problems solved by technology

[0004] The sewage treatment effect of biological filter bed technology is closely related to the sewage treatment load. However, the discharge of low-pollution water varies greatly, and sewage collection is difficult. For low-pollution water treated in a decentralized manner, land acquisition for treatment is difficult, which leads to ecological filter in the design process. The footprint in the area is often much lower than the requirements of the sewage treatment load

Therefore, the application of biological filter bed in low-pollution water treatment, with the prolongation of operation time, on the one hand, the clogging becomes more and more serious, on the other hand, the pollutant removal effect is very unsatisfactory.
