摘要
针对北京市通州区分散式污水处理厂站节约占地、出水水质指标要求高特点,以某分散式污水工程A/O+MBR工艺为例,对2018年1-12月工艺运行情况分析。运行结果表明:AO+MBR工艺全年对COD、NH_(4)^(+)-N、TN和TP的平均去除率分别为91.97%、98.83%、66.24%、92.68%,沿程水质数据分析说明COD、NH_(4)^(+)-N及TN在第一级生化罐完成大部分污染物去除。工艺运行费用约5.14元/吨,该工艺适用于对出水水质要求高或者有回用需求的地区。
A/O+MBR process aiming at saving land and higher effluent quality was applied at a decentralized wastewater project in Tongzhou District,Beijing.The operating results showed that the average removal rates of COD,NH_(4)^(+)-N,TN and TP were 91.97%,98.83%,66.24%and 92.68%,respectively.The quality along the units of system showed that most of COD,NH_(4)^(+)-N and TN were removed in the first biochemical tank.The operating cost was about 5.14 yuan/t;Thus,the process was suitable to the area where the higher effluent quality or water reuse was strongly required.
