Problems solved by technology

For example, most of the new processes only emphasize the removal of nitrogen, while the treatment of phosphorus is less involved, and the high concentration of phosphorus has an inhibitory effect on processes such as anaerobic ammonium oxidation; many new processes have strict requirements on the quality of wastewater Harsh, the chemical oxygen demand (COD) in the wastewater during the treatment process should not be too high; the structure and operation of the treatment equipment are

Abstract

The invention discloses a denitrifying phosphorus removal-anammox-shortcut nitrification integrated baffled reaction equipment, relating to a wastewater treatment device. The equipment disclosed by the invention is baffled reaction equipment which is suitable for achieving decarbonizing and denitriding and dephosphorization synchronously for wastewater with a low carbon-nitrogen ratio and wastewater with a high carbon-nitrogen-phosphorus concentration. The integrated baffled reaction equipment makes use of the biofacies separation characteristic and achieves coupling microorganisms with denitrifying phosphorus removal, anammox and shortcut nitrification functions through a backflow device and an aerating device so as to achieve decarbonizing and denitriding and dephosphorization synchronously for the wastewater with the low carbon-nitrogen ratio and wastewater with the high carbon-nitrogen-phosphorus concentration, and reduce organic carbon source consumption amount in the treatment process to a lower level to largely reduce produced surplus sludge. Packing layers are arranged in autotrophic functional microorganism cells to raise biological holding volume for the system. The device has advantages of simple structure, multifunction, low consumption and high efficiency, easy operation and management, stable operation and so on. The device can also achieve decarbonizing and denitriding and dephosphorization synchronously.

Description

technical field [0001] The patent of the invention relates to a reaction device for synchronous decarbonization, nitrogen and phosphorus removal of waste water with low carbon-to-nitrogen ratio and waste water with high carbon, nitrogen and phosphorus concentration. It belongs to the field of water pollution control. Background technique [0002] In recent years, with the development of the economy, the content of nitrogen and phosphorus elements (especially ammonia nitrogen) in industrial, agricultural and urban domestic sewage is getting higher and higher. A large amount of nitrogen and phosphorus wastewater is directly discharged into the water body without proper treatment, seriously polluting the water body environment, leading to severe eutrophication of a large number of rivers and lakes, frequent occurrence of coastal red tides, and serious harm to human health. The contradiction of shortage seriously restricts the implementation of sustainable development strategy....
