Abstract

A deep biological denitrification apparatus for sewage comprises an anoxic tank, a deep denitrification bin, a clear water tank and a backwash aeration system; the anoxic tank, the deep denitrification bin and the clear water tank are sequentially connected to form an integrated denitrification treatment box body, and a wastewater tank is arranged at one side of the deep denitrification bin; the backwash aeration system comprises a backwash aeration device and a backwash device, the backwash aeration device is provided with the deep denitrification bin and is connected with a variable-frequency air blower, one end of the backwash device is connected with the deep denitrification bin, and the other end of the backwash device is connected with the clear water tank; and a central centralizedcontroller and a total nitrogen detector are respectively arranged at the outer side of the deep denitrification bin, and the total nitrogen detector is provided with a detection head connected with the deep denitrification bin. The deep biological denitrification apparatus has the advantages of reasonable structure, high reaction efficiency and good denitrification function.

Description

technical field [0001] The invention belongs to the related field of sewage treatment equipment, and in particular relates to a deep biological denitrification device for sewage. Background technique [0002] With the development of my country's economy and the advancement of urbanization, the shortage of water resources and the aggravation of water pollution have become increasingly severe, and the requirements for sewage treatment and reuse have become increasingly urgent. Traditional centralized sewage treatment has difficulties in sewage collection and high investment in pipe networks. , Large footprint, long construction period and other outstanding problems seriously restrict the sewage treatment rate and COD emission reduction. In this case, decentralized sewage treatment integrated technology equipment has become a beneficial and necessary supplementary measure for centralized sewage treatment. [0003] Although ammonia nitrogen in wastewater can be treated by physica...
