Engineering example of treating domestic sewage by MUCT process

This paper will discuss the application of MUCT in treating domestic sewage at a factory in Guangdong.In particular,the paper introduces the process design parameters,process characteristics,operation results and operation cost for using MUCT as main process.The processing capacity of waste water at this plant is 6000t/d,and the COD,BOD5,SS and TP of inflow are 300mg/L,200mg/L,250mg/L and 4mg/L respectively.The removal rate of COD,BOD5,SS and TP are 88.3%,96%,86% and 87.5% respectively with the effluent qualities of 35mg/L,8mg/L,35mg/L and 0.5mg/L respectively.The effluent quality meets the second stage Ⅰ class standard for water pollutant emission limit value(DB44/26-2001,Guangdong local standard).The treatment cost is 0.665yuan/ton.This MUCT process has demonstrated an excellent treatment effect and low cost for nitrogen and phosphorus removal.
