四川某乡镇污水处理厂站提标改造项目设计案例分析

Study on the design of upgrading project of town sewage treatment plant in Sichuan

随着对环保的要求越来越高,乡镇污水处理厂站的运营至关重要。以四川某乡镇污水处理厂站提标改造项目为实例,对设计工艺进行对比分析,涵盖现有污水处理全过程:污水可生化分析、预处理、二级处理、深化处理、消毒、污泥处置等,最终确定污水工艺调整为“Cwater-HRB生化+过滤+紫外消毒”工艺,经工程验证,该工艺不仅实现社会效益及经济效益的最大化,还满足当前乡镇的区域特征,为类似工程设计提供一定借鉴。

With the increasing demand for environmental protection,the operation of township sewage treatment plant is very important.In this paper,taking the upgrading project of a town sewage treatment plant in Sichuan Province as an example,the design process is compared and analyzed,covering the whole process of existing sewage treatment:biochemical analysis,pretreatment,secondary treatment,deepening treatment,disinfection,sludge disposal,etc..Finally,it is determined that the sewage process is adjusted as“cwater-hrb biochemical+filtration+UV disinfection”process.Which is verified by the project,it can not only maximize the social and economic benefits,but also meet the regional characteristics of the current township,and provide some reference for similar engineering design.
