Analysis Of Operation Status Of Liuhe Sewage Plant And Research On Its Extension And Upgrading

Due to rapid economic development of Liuhe in recent years,the population scale expansion,sewage treatment plant daily processing capacity is close to the size of the existing 10000 m3/d,extension of existing sewage treatment plant scale has become very necessary.In response to the state’s call for environmental quality,analysis of the operating conditions of the present sewage treatment plant,the process route of "pretreatment + main biochemical treatment + deep treatment process" has been put forwarded.It is expected that the effluent can reach the standard of special emission limit in the standard for pollutant discharge of urban sewage treatment plant.This paper predicts the capacity of the sewage treatment plant after expansion,and demonstrates the rationality of the upgrading of the influent water quality of the sewage plant after the expansion compared with the index of the influent quality of the original sewage plant.It is feasible to improve the effluent quality by improving the sewage treatment facility.For some problems existing in the current sewage treatment plant,combined with the requirements of the extension to the effluent,the main biochemical process is discussed,the treatment equipment is improved,the deep bed filter technology is introduced,and the original technological parameters are optimized and improved.
