Landscape ecology type decentralization sewage treatment process and device

Abstract

The invention provides a landscape ecology type decentralization sewage treatment process. The landscape ecology type decentralization sewage treatment process comprises a reaction tank and plants planted on the reaction tank, and the following steps are carried out in the reaction tank: S1, adding water; S2, carrying out anaerobic treatment; S3, carrying out aerobiotic treatment; S4, carrying out anoxic treatment; S5, settling; and S6, draining water. The invention further provides a landscape ecology type decentralization sewage treatment device. The process has the beneficial effects that the conventional SBR process is combined with landscape plants, pollutant removal efficiency is strengthened by virtue of physiological actions of the plants, the plant root system also can be used as a carrier for attaching microorganisms; the plants, the root system microorganism and active sludge act together to greatly improve nitrogen and phosphorus removal efficiency of the SBR process; the landscape plant also can greatly improve a surrounding environment of a sewage treatment facility and a produced bad smell problem; and meanwhile, the sewage treatment facility can be used as a landscape leisure site.

Description

technical field [0001] The invention relates to a waste water treatment process, in particular to a landscape ecological distributed sewage treatment process and a device thereof. Background technique [0002] With the rapid development of economy and society and the improvement of living standards, people have higher requirements for the comfort of the living environment. Sewage treatment plants are not only operated as sewage treatment facilities, but also have higher and higher requirements. Sewage treatment The impact of the facilities on the surrounding environment needs to be improved urgently. my country's water pollution and water resource shortages are becoming more and more serious, and higher requirements are placed on the effect of sewage treatment. However, due to the improvement of urban sewage treatment and discharge standards, the efficiency of nitrogen and phosphorus removal cannot be further improved due to the bottleneck of the traditional activated sludg...

AI Technical Summary

Problems solved by technology

If the water treatment is to run continuously, it is necessary to set up a multi-tank system and increase infrastructure investment

Secondly, for some high-concentration and refractory organic wastewater, a longer reaction time is required

Thirdly, the SBR process operation is more complicated, automatic control must be adopted, and there are many ancillary facilities

In addition, since the process tank is mostly open, it has a great impact on the surrounding environment during operation, especially when it is operated as a decentralized sewage treatment facility, the odor problem generated by this process limits its wide application. one of the main problems
