Abstract

The invention provides an anaerobic-SBR-SACR combined deep denitrification system and process for high-ammonia-nitrogen sewage. According to the process, high-ammonia-nitrogen sewage firstly enters ananaerobic reactor for removal of most of organic matters; the effluent of the anaerobic reactor sequentially enters an SBR water inlet tank and an SBR reactor, and pre-denitrification and nitrification are carried out through the SBR to remove biochemical organic matters, ammonia nitrogen and a part of total nitrogen; the effluent of the SBR reactor enters an intermediate water tank; under the control of water quality detection equipment and a PLC, a part of raw water is introduced into the intermediate water tank to adjust the carbon-nitrogen ratio of the sewage; and then the effluent entersan SACR reactor. By utilizing the characteristics of denitrifying bacteria and by regulating and controlling the SACR reactor via a PH / DO / ORP detector and the PLC, the sewage is accurately subjectedto pre-denitrification / nitrification / endogenous denitrification, so deep denitrification is realized; meanwhile, an external carbon source is not needed, and the cost of the process is low; and for abuilt sewage treatment facility adopting an SBR process, the process with the above technical scheme can be implemented only by additionally arranging the intermediate water tank and the SACR reactor,so upgrading and reconstruction cost is low.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an anaerobic-SBR-SACR combined deep denitrification system and process for high ammonia nitrogen sewage. Background technique [0002] At present, with the strengthening of environmental protection awareness, the strengthening of environmental pollution control and the development of environmental protection technology, water pollution has been relatively effectively controlled initially. However, the standard discharge of high-ammonia-nitrogen wastewater common in industrial production is still an urgent problem. The problem. High ammonia nitrogen wastewater mainly comes from chemical fertilizer, petrochemical, aquaculture, garbage treatment and other industries. In terms of high ammonia nitrogen wastewater treatment, it is not only necessary to pursue the technical indicators of efficient denitrification, but also to consider reducing energy consumption, saving energy ...
