Problems solved by technology

For example, most of the new processes only emphasize the removal of nitrogen, and less involve the treatment of phosphorus, and high concentrations of phosphorus have an inhibitory effect on processes such as anaerobic ammonium oxidation; many new processes have strict requirements on sewage water quality , the chemical oxygen demand (COD) of sewage during the treatment process should not be too high; the device structure and operation process are relatively complicated, the biological holding capacity is low, the system operation is unstable, and it is easily affected by changes in external environmental conditions and different functions in the system Microorganisms are easy to interact with each other, making the reactor treatment efficiency low, so it is difficult for the new process to achieve simultaneous decarbonization, nitrogen and phosphorus removal of low C / N ratio sewage and high carbon, nitrogen and phosphorus wastewater

Abstract

The invention discloses a denitrification phosphorus removal-nitrosation-based whole-course autotrophic nitrogen removal integrated baffling reaction device. The device consists of three cell chambers, namely a denitrification phosphorus removal functional cell chamber, an anaerobic ammonia oxidation functional cell chamber and a short-cut nitrification functional cell chamber, and a settling chamber; gas-collecting tubes are arranged at the top; each cell chamber is divided into two flow chambers by a guide plate, namely a downward flow chamber and an upward flow chamber; inclined flow guideplate water distribution is arranged on the edge of the lower portion of each flow guide plate leading to each upward flow chamber, and triangular areas are intercepted on two sides of the bottom of each cell chamber. The coupling of microorganisms with three different functions including denitrification phosphorus removal, anaerobic ammonia oxidation and short-cut nitrification is realized, so that the synchronous decarburization nitrogen and phosphorus removal of low C / N sewage and high-carbon nitrogen and phosphorus sewage is realized.

Description

technical field [0001] The invention belongs to the field of water pollution control, and in particular relates to a reaction device for synchronous decarbonization, nitrogen, and phosphorus removal of sewage with low carbon-to-nitrogen ratio and sewage with high carbon, nitrogen, and phosphorus concentrations. Background technique [0002] In recent years, with the development of the economy, human activities have caused eutrophication of water bodies, such as the discharge of industrial, agricultural and urban domestic sewage, and accidental leakage of industrial pollutants, making the content of nitrogen and phosphorus elements (especially ammonia nitrogen) in water bodies more and more The higher it is, the water environment will be seriously polluted and the human health will be seriously endangered. In addition, water pollution has further exacerbated the current situation of my country's water shortage, seriously restricting the implementation of sustainable developme...
