摘　　要：城镇污水处理厂的污水提升泵是污水处理中最重要的一个环节,往往通过提升泵将来水提升至污水厂内最高点,通过高低程压差自流至其他处理单元。由于污水中含有大量的腐蚀性物质,在提升泵管道支架焊接处会出现不同程度的腐蚀。尤其运行年头较长的污水处理厂,在全年满产不具备减产、停产的情况下如何更换腐蚀严重的提升泵管道是一个困扰污水处理厂运行的难题。此文提供了一种可做到在无减产、零有限空间作业的前提下完成提升泵管道更换方法,具有水量波动小,能源消耗低,更高的安全性等优势。The sewage lifting pump in urban sewage treatment plants is the most important link in sewage treatment,often lifting the incoming water to the highest point in the sewage plant through the lifting pump,and flowing to other treatment units through the high and low pressure difference.Due to the presence of a large amount of corrosive substances in sewage,varying degrees of corrosion will occur at the welding points of the pump pipeline support.Especially for sewage treatment plants that have been in operation for a long time,it is a difficult problem to replace severely corroded lifting pump pipelines when they are not able to reduce or shut down production at full capacity throughout the year.This article provides a method for replacing pump pipelines without reducing production or operating in limited space,which has the advantages of small water volume fluctuations,low energy consumption,and higher safety.
