Denitrification IBR nitrogen and phosphorus removal integrated reactor and reaction process thereof

Abstract

The invention discloses a denitrification IBR nitrogen and phosphorus removal integrated reactor and a reaction process thereof. The denitrification IBR nitrogen and phosphorus removal integrated reactor is of a semi-closed structure and is provided with a plurality of inner cavity areas separated from one another, and the denitrification IBR nitrogen and phosphorus removal integrated reactor comprises an IBR reaction area, an anoxic area, a settling area and a filtering area; the anoxic area, the filtering area and the settling area are annularly arranged around the IBR reaction area in the anticlockwise direction, and the IBR reaction area, the settling area and the filtering area are sequentially communicated in the liquid flowing direction; specifically, a plurality of submersible sewage pumps, a plurality of aerators, a plurality of connecting pipes and second return pipes are arranged in the IBR reaction area; a liquid inlet of each submersible sewage pump is communicated with aliquid outlet of the anoxic area through a second return pipe; and a liquid outlet of each submersible sewage pump is communicated with the IBR reaction area through a connecting pipe and an aerator in sequence.

Description

technical field [0001] The invention relates to the field of sewage purification, in particular to a denitrification IBR integrated reactor for nitrogen and phosphorus removal and a reaction process thereof. Background technique [0002] In recent years, with the development of my country's economy and the improvement of people's living standards, the content of nitrogen and phosphorus in urban domestic sewage has increased significantly, which has increased the treatment load of sewage treatment plants and increased the cost of sewage treatment. When a large amount of organic matter, nitrogen, phosphorus and other nutrients in urban sewage are discharged into the water body, it will cause water pollution and eutrophication, and the intensification of eutrophication can further cause black and odorous water bodies. Therefore, my country promulgated in 2002 the "Pollutant Discharge Standards for Urban Sewage Treatment Plants" (GB18918-2002), the first-level A standard, which ...
