Segmented water feeding and coupling integrated anaerobic ammonium oxidization SBBR further denitrification control system

Abstract

The invention relates to a segmented water feeding and coupling integrated anaerobic ammonium oxidization SBBR further denitrification control system, which belongs to the field of sewage biological treatment. The segmented water-inlet coupling integrated anaerobic ammonium oxidization SBBR further denitrification control system comprises an urban sewage water tank, an SBBR reactor, a PLC controlcabinet and a computer. The urban sewage is pumped into the SBBR reactor, after the primary water feeding, denitrification bacteria use organic matters in the sewage to remove residual nitrite nitrogen and nitric nitrogen in the reactor, and the remaining organic matters are stored in a bacterial body to synthesize an internal carbon source; and after the reaction is ended, the aeration is startedto perform the integrated anaerobic ammonium oxidization denitrification. After the aeration is ended, the water is fed secondarily, the nitric nitrogen generated by virtue of the anaerobic ammoniumoxidization reaction is removed by virtue of denitrification, and the internal carbon source is stored, after the reaction is ended, the aeration is performed again to remove the ammonia nitrogen in the secondarily fed water, and the nitric nitrogen is generated. After the secondary aeration is completed, the stored internal carbon source is used for performing the denitrification so as to furtherreduce the nitrogen concentration in the outlet water. The segmented water feeding and coupling integrated anaerobic ammonium oxidization SBBR further denitrification control system, can realize thefurther denitrification of the urban sewage with low carbon-nitrogen ratio, and is simple in operation, and capable of saving the energy and reducing the consumption.

Description

technical field [0001] The invention relates to a control system for segmented water inflow coupling integrated anaerobic ammonium oxidation SBBR deep denitrification, and belongs to the technical field of sewage biological treatment. Background technique [0002] In order to avoid eutrophication of water body, denitrification and phosphorus removal of sewage has become a routine treatment project of urban sewage treatment plants, and the deep denitrification of urban sewage with low carbon-to-nitrogen ratio is a bottleneck problem. When the traditional biological nitrification and denitrification technology treats urban sewage, due to the lack of organic matter in the sewage, it often fails to achieve a good denitrification and denitrification effect, and the operating energy consumption is high. [0003] Segmented water inflow technology refers to the operation process of strengthening heterotrophic denitrification and denitrification by making full use of the organic matt...
