Embodiment Construction
[0021] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.
[0022] In order to solve the problems existing in the prior art, such as the difficulty in the enrichment of functional flora and the low load of ammonia nitrogen removal, the present invention provides an enhanced sewage autotrophic denitrification reactor and method, which realizes particle-based biofilm denitrification in the same reactor. The coupling of the two technologies of microbial immobilization and membrane interception-based enrichment of suspended bacteria can increase biomass and its reactivity, and effectively remove ammonia nitrogen, organic matter and suspended matter in sewage.
[0023] Such as figure 1 As shown, in the embodiment of the present invention, an enhanced sewage full autotrophic denitrification reactor mainly includes a reaction tank 10 and a microporous aerator 5 , a guide tube 8 and a membrane module 9 arranged ...

The invention relates to an intensifying sewage whole-course autotrophic nitrogen removal reactor and an intensifying sewage whole-course autotrophic nitrogen removal method, and belongs to the technical field of environmental protection and sewage treatment. The intensifying sewage whole-course autotrophic nitrogen removal reactor mainly comprises a reaction tank, a micropore aerator, a flow guide cylinder and a membrane assembly, wherein the micropore aerator, the flow guide cylinder and the membrane assembly are arranged in the reaction tank; the micropore aerator is arranged just below the flow guide cylinder and generates microbubbles for forming gas stripping action and controlling membrane pollution; the flow guide cylinder is arranged on the central position of the reaction tank; the membrane assembly is arranged in the flow guide cylinder. According to the intensifying sewage whole-course autotrophic nitrogen removal reactor, the culture and enrichment of internal functional microbes are fast completed through granular activated carbon addition and hydraulic screening modes; on the one hand, the microbes are immobilized through a granular type biological membrane, on the other hand, the microbes are enriched in a suspended state form by dint of the high-efficiency interception effect of the membrane assembly; all microbes take circulating motion up and down inside and outside the flow guide cylinder with sewage under the gas stripping action. The intensifying sewage whole-course autotrophic nitrogen removal reactor disclosed by the invention can greatly enhance the whole-course autotrophic nitrogen removal biomass and the reaction activity and ensure the higher effluent water quality.
Description
technical field [0001] The invention belongs to the technical field of environmental protection and sewage treatment, and in particular relates to a reactor and method for strengthening the whole process autotrophic denitrification of sewage. Background technique [0002] Sustainable development and carbon emission reduction have always been important development goals and trends in the field of environmental protection and sewage treatment technology. The traditional denitrification technology based on the principle of nitrification-denitrification not only needs to consume a large amount of electric energy for aeration and oxygenation in the aerobic nitrification stage, but also needs enough organic carbon sources for the denitrification process, which has high energy consumption, high land occupation, and high emissions. Carbon and other disadvantages. In addition, due to the common phenomenon of insufficient organic carbon sources in sewage, especially for concentrated ...
