摘要
济南某污水处理厂工程设计规模为4万m3/d,二级处理采用改良Bardenpho工艺,同时通过设置多点进水、碳源多点投加,前端设置预缺氧池,增设二级缺氧/好氧可变段等措施,为污水厂提供多种工艺运行模式.运行结果表明:改良Bardenoho工艺对CODcr、NH3-N、TN、TP等污染物去除率分别达到了 94.98％、98.35％、93.95％、79.68％,出水CODcr、NH3-N、TN、TP分别为 11.7、0.68、3.03、0.77 mg/L,除TP尚需通过深度处理强化去除外,其余指标均优于设计出水水质.
Abstract
The design scale of a wastewater treatment plant(WWTP)project in Jinan is 40 000 m3/d,and the improved Bardenpho process is used for the secondary treatment.At the same time,by setting up the multi-point inflow and the multi-point carbon addition,the pre-anaerobic is constructed at the front end,and the secondary anaerobic/aerobic changeable section is added,which provide the multiple technological operation modes for WWTP.The operation result shows that the pollutant removal rates of CODCr,NH3-N,TN and TP by the modified Bardenoho process are 94.98％,98.35％,93.95％and 79.68％respectively,and the effluent CODCr,NH3-N,TN and TP are 11.7,0.68,3.03 and 0.77 mg/L respectively.Except for TP,which need to be enhanced by the advanced treatment,and the other indexes are all better than the designed effluent qualities.
