An integrated autotrophic biological denitrification synergistic chemical phosphorus removal reactor

Abstract

An integrated autotrophic biological nitrogen removal collaborative chemical phosphorus removal reactor, which comprises a reactor body, a plurality of partitions and sleeves. The reactor body is provided with a water distribution unit, a deslagging unit, a reaction unit, a three-phase separation unit and a water outlet exhaust unit from the bottom to top. The reaction unit is divided by the partitions and the sleeves into a whole-process autotrophic denitrification reaction zone, a chemical phosphorus removal zone, a reflux dissolution zone and a denitrification nitrogen removal zone. The water distribution unit is provided with a water inlet and an aeration head. The deslagging unit is located at the bottom end of the reflux dissolution zone and chemical phosphorus removal zone of the reactor, and is provided with a slag discharging port. The three-phase separation unit is arranged on the top of the whole-process autotrophic nitrogen removal reaction zone and the denitrification zone and is provided with a flow guide partition. The water outlet exhaust unit comprises a water outlet tank, a water outlet, a gas collecting hood and an exhaust port. The invention has the beneficial effects that dissolved iron, slag and other industrial wastes are used to provide a nitrogen matrix, so as to save carbon sources, reach thorough denitrification, realize treatment of wastes with processes of wastes against one another, recycling of the phosphorus resource waste and achieve many things at one stroke.

Description

technical field [0001] The invention relates to an integrated autotrophic biological denitrification synergistic chemical phosphorus removal reactor. Background technique [0002] In recent years, the excessive discharge of wastewater containing nitrogen and phosphorus has caused a series of ecological and environmental problems such as eutrophication of water bodies. The high-efficiency and low-consumption treatment of wastewater containing ammonia nitrogen and phosphate has always been a difficult problem in the field of sewage treatment. In the face of wastewater with a low C:N:P ratio, traditional nitrification-denitrification processes and anaerobic-aerobic biological phosphorus removal technologies are now available. Qian donkeys are poor. [0003] High iron salt chemical phosphorus removal technology has the advantages of high phosphorus removal efficiency and strong stability, but its large consumption and high cost restrict its wide application. [0004] The integ...
