Abstract

The invention relates to a total nitrogen treatment device, and relates to the technical field of wastewater treatment. The total nitrogen treatment device comprises an inorganic nitrogen treatment mechanism and an organic nitrogen treatment mechanism, the inorganic nitrogen treatment mechanism comprises a hydrolysis acidification pool, an anoxic pool and an aerobic pool, the hydrolysis acidification pool communicates with the anoxic pool, the anoxic pool communicates with the aerobic pool, and the aerobic pool communicates with the hydrolysis acidification pool; and the organic nitrogen treatment mechanism comprises a sedimentation tank, and the anoxic pool or the aerobic pool communicates with the sedimentation tank. According to the invention, organic matter in the wastewater can be utilized, the dissolved oxygen content of the wastewater before denitrification reaction is reduced, available carbon sources in the wastewater are increased, proliferation of denitrifying bacteria is accelerated, the treatment efficiency of inorganic nitrogen is improved, and the treatment time of the inorganic nitrogen is shortened.

Description

technical field [0001] The present application relates to the field of waste water treatment, in particular to a total nitrogen treatment device. Background technique [0002] Municipal wastewater refers to urban residential wastewater, drainage from institutions, schools, hospitals, commercial service agencies and various public facilities, as well as industrial wastewater and initial rainwater that are allowed to be discharged into urban wastewater collection systems. The current discharge standard implements the "Pollutant Discharge Standard for Urban Wastewater Treatment Plants - GB18918-2002", in which, in addition to BOD5, COD, SS, pH, total phosphorus, total nitrogen, ammonia nitrogen, fecal coliform number, etc. must meet the requirements standard. [0003] At present, the public date is December 04, 2020, and the Chinese invention patent application with the publication number CN112028413A proposes a high total nitrogen wastewater treatment device, a primary aerobi...
