Abstract

The invention relates to a waste water treatment system, in particular to a circulating closed ammonia nitrogen stripping system. The system mainly solves the technical problems of low efficiency, high energy consumption, heavy secondary pollution, instable operation, high temperature requirement of a stripping process, low stripping efficiency in cold winter, need of heating waste water, high treatment cost and the like in the prior art. The system provided by the invention comprises a waste water circulating pool, wherein the waste water circulating pool is connected with a stripping liquidinlet pump; the stripping liquid inlet pump is connected with a stripping tower; the stripping tower is communicated with the waste water circulating pool; a waste water spraying device is arranged in the stripping tower and on the top; a filler layer is fixed below the waste water spraying device; the top of the stripping tower is connected with an absorption tower through a waste gas pipe; a filler layer is fixed in the absorption tower; the top of the absorption tower is connected with a stripping fan through a pipe; the stripping fan is arranged at the bottom of the stripping tower and iscommunicated with the stripping tower; and the waste water circulating pool is also connected with a pH reversely regulating pool through a clean water pipe.

Description

technical field [0001] The invention relates to a waste water treatment system, in particular to a circulating closed-loop ammonia nitrogen stripping system. Background technique [0002] Ammonia nitrogen wastewater has a wide range of sources and a large amount of discharge, such as chemical fertilizers, coking, petrochemicals, pharmaceuticals, food, landfills, etc., all produce a large amount of high-concentration ammonia nitrogen wastewater. The discharge of a large amount of ammonia nitrogen wastewater into the water body will not only cause eutrophication of the water body, cause the water body to be black and smelly, but also increase the difficulty and cost of water supply treatment, and even cause poisonous effects on people and organisms. There are many methods for the treatment of ammonia nitrogen, such as breakpoint chlorination, chemical precipitation, biochemical, electrochemical, etc. These methods have high treatment costs and immature technology, and can only...
