Integrated anaerobic ammonia oxidation device for treating urban sewage and operation method thereof

Abstract

The invention relates to an integrated anaerobic ammonia oxidation device for treating urban sewage and an operation method thereof. The integrated anaerobic ammonia oxidation device comprises an urban sewage raw water tank, a high-load bioreactor, an intermediate regulating water tank, an integrated anaerobic ammonia oxidation reactor, a biological intensification reactor, a metering pool, an on-line monitoring detector and an automatic control system; the urban sewage raw water tank is connected with the high-load bioreactor through a high-load bioreactor water inlet pump; a drainage pipe of the high-load bioreactor is connected with the intermediate regulating water tank; the sewage in the intermediate regulating water tank is respectively connected with the integrated anaerobic ammonia oxidation reactor, the biological intensification reactor and the metering pool through a three-in-one water inlet pump. The integrated anaerobic ammonia oxidation device provided by the invention has the characteristics of being reasonable in structural design, high in degree of automation, reliable and stable in overall operation and the like, can effectively realize the nitrogen and phosphorus removal of the urban sewage and breaks through the problems of insufficient carbon source, low nitrogen removal rate, high residual sludge yield and the like when a traditional nitrogen and phosphorus removal process is adopted for treating the urban sewage.

Description

technical field [0001] The invention belongs to the technical field of sewage biological treatment, and relates to an integrated anaerobic ammonium oxidation device for treating urban sewage and an operation method thereof. Background technique [0002] The eutrophication of water bodies caused by nitrogen and phosphorus pollution has always been one of the main problems faced by countries all over the world, and it is also the difficulty and focus of water treatment. As we all know, urban sewage is one of the important sources of water pollution. Our country treats more than 46 billion tons of sewage every year, and most of them are processed by traditional processes at the expense of energy and resources. With the increasingly stringent national standards for sewage discharge, it is urgent to explore new processes for nitrogen and phosphorus removal in the sewage treatment process, improve the treatment effect of sewage, break through the traditional high energy consumptio...
