Scattered sewage treatment device and method for treating sewage by using scattered sewage treatment device

Abstract

The invention belongs to the field of sewage treatment, and particularly relates to a scattered sewage treatment device and method for treating sewage by using the scattered sewage treatment device. The device comprises a central treatment tank, wherein the central treatment tank is a first septic chamber; ten treatment tanks are arranged on the periphery of the central treatment tank and surround the periphery of the central treatment tank; the ten treatment tanks clockwise and sequentially comprise a second septic chamber, a third septic chamber, six aerobiotic / anoxic synchronous tanks, a clarifying tank and a clear water tank. The design philosophy of scattered sewage treatment is proposed, integrated sewage treatment equipment is small in size and is carried flexibly, space of a building is saved effectively, and utilization costs for lands are reduced; and the investment of a pipe network is reduced to a maximum extent, and sewage can be locally collected, treated and reused from the source. By a highly integrated sewage treatment technology, good denitrification conditions can be provided under the anoxic condition, and the denitrification effect of a system is strengthened. The standing time of sewage in a reactor is shortened, occupied area of the reactor is greatly reduced, and the market prospect and the economic value are quite high.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a distributed sewage treatment device and a sewage treatment method using the same. Background technique [0002] The "Thirteenth Five-Year Plan" emphasizes that rural areas are the top priority, and environmental issues are a prominent shortcoming. The rural environment is not only the weakest difficulty, but also the most potential breakthrough point and innovation point. At present, most rural sewage in our country has not been effectively treated and is discharged in an orderly manner. How to achieve economical and effective rural sewage treatment has become a bottleneck restricting the development of the industry. The research and development of effective rural decentralized sewage treatment technology and high-efficiency and low-consumption integrated equipment is of great significance to respond to the "13th Five-Year Plan" and improve the rural environment. ...

AI Technical Summary

Problems solved by technology

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the bottlenecks of large investment in pipe network construction, high operation and maintenance costs, and poor treatment effect in the treatment of rural domestic sewage, thereby proposing an easy-to-operate, effective, and low-cost Distributed sewage treatment device
