Abstract

The invention relates to a reverse-sequence CABBR sectional water inlet enhanced denitrification process, which comprises a screening pool, a reverse-sequence CABBR pool, a water inlet pipe, a water outlet pipe, an internal reflux pipe, an air inlet pipe and an aeration head, wherein the screening pool and the reverse-sequence CABBR pool are connected through a pipeline, the screening pool and thereverse-sequence CABBR pool are respectively fixedly provided with the water inlet pipe and the water outlet pipe, the air inlet pipe is fixedly arranged in the reverse-sequence CABBR pool, the waterinlet pipe is connected with a water inlet pump, the input end of the air inlet pipe is connected with an air blower, the output end of the air inlet pipe is connected with the aeration head, a submersible stirrer is fixedly arranged in the bottom of the reverse-sequence CABBR pool, and a dissolved oxygen (DO) sensor, an oxidation-reduction potential (ORP) sensor and a pH sensor are fixedly mounted on the inner wall of the reverse-sequence CABBR pool respectively. According to the technical scheme, an excellent optimization scheme is utilized, and the problems existing in traditional water body denitrification are solved.

Description

technical field [0001] The invention relates to the technical field of biological denitrification, in particular to a reverse sequence CABBR segmented water inflow enhanced denitrification process. Background technique [0002] Phosphorus in sewage pollutants can be removed by chemical or biological methods, while nitrogen can only be removed by biological methods. The traditional biological denitrification treatment adopts a two-stage method, that is, ammonia nitrogen is oxidized to nitrate nitrogen under aerobic conditions, Nitrate nitrogen is then reduced to nitrogen under anoxic conditions. Therefore, two reactors are generally required for two different processes. CAST (Cyclic activated sludge technology, circulating activated sludge process) is a SBR (Sequencingbatch reactor , a variant of the batch activated sludge method), because of its low investment and operating costs, simple and flexible operation and its selector can prevent sludge bulking and synchronous nitri...
