Abstract

The invention relates to an aerobic sedimentation pond for sewage treatment, which is characterized in that one end of a pond body is provided with a water inlet weir gate, the other end of the pond body is provided with a water outlet weir gate, the bottom of the pond body is provided with a sludge hopper, at least two separation barrels are arranged in the pond body, and an aeration pipe is arranged in each separation barrel. The aerobic sedimentation pond is provided with a plurality of regional separation barrels, the aeration pipe arranged in each separation barrel forms ascending current of mud-water mixed liquid in the local region, and the ascending current flows through an anoxic region and an aerobic region, overflows from the upper edges of the regional separation barrels and refluxes to an anaerobic region on the bottom layer to perform denitrification reaction in a cyclic process. Due to the plurality of regional separation barrels, the reaction process is repeated so as to greatly improve the reaction depth and efficiency of nitration and denitrification.

Description

Technical field: [0001] The invention relates to the technical field of sewage treatment industry, in particular to an aerobic / sedimentation tank for batch activated sludge process. Background technique: [0002] In the sewage biochemical treatment system, the pool is an indispensable and important part. A sewage biochemical treatment system is always composed of several pools, and each pool is given different technological tasks, such as anaerobic reaction pool, aerobic reaction pool, secondary settling pool, regulating pool, etc. In engineering implementation, it is always hoped that each reaction pool can complete the task indicators required by the process design and be as perfect as possible. Therefore, in the design process of various reaction pools, the shape of the pool, the structure of the pool, and the selection and installation of equipment have been carefully selected and arranged. These selections and arrangements follow the following principles: [0003] (1...
