碱渣尾气吸收碱液用于污水汽提装置注碱的探讨

介绍了碱渣尾气吸收碱液在污水汽提装置注碱的试验情况，探讨了在注碱过程中应注意的问题，经过试验及二年多的生产运行表明，碱渣尾气吸收碱液用于污水汽提装置注碱是可行的，污水汽提装置运行平稳，塔底净化水的水质仍维持在较高水平，同时也消除了碱渣尾气吸收碱液的恶性循环，有效地控制了恶臭污染的发生。

A Case Study of Spent Caustic Solution After Tail Gas Absorption Used as Sewage Stripper Caustic Injection

This paper gives an introduction to the test to use spent caustic solution after tail gas absorption as caustic injection for sewage stripping ,and offers some discussions aroud the attention-worthy points for such a caustic injection.The test and a nearly two-year production operation have sttests the feasibility of the spent caustic solution after tail gas absorption to be used as caustic injection for sewage the approach has eliminated the vicious cycle of the spent caustic solution as a result of absorbing tail gas ,effectively controlling stinky smell pollution from occurring.
