摘要
某电厂循环外排水主要来源于电厂循环水系统中凝汽器不断循环,使机组降温的水.有可生化性较差、有机物浓度较低、硬度较大等特点,某电厂的综合污水处理厂采用AO+芬顿反应池+BAC组合工艺处理此污水,出水水质执行《城镇污水处理厂污染物排放标准》(GB18918-2002)一级A排放标准,结果显示,AO+芬顿反应池+BAC组合工艺能使出水稳定达到标准.
Abstract
The circulating external drainage of a certain power plant mainly comes from the continuous circulation of the condenser in the circulating water system of the power plant,which cools the unit.Due to its poor biodegradability,low organic matter concentration,and high hardness,the comprehensive sewage treatment plant of a certain power plant adopts the AO+Fenton reaction tank+BAC combination process to treat this wastewater.The effluent quality follows the Class A discharge standard of the"Pollutant Discharge Standard for Urban Sewage Treatment Plants"(GB18918-2002).The results show that the AO+Fenton reaction tank+BAC combination process can ensure that the effluent meets the standard stably,with CODCr,total nitrogen The total phosphorus removal rates were 85%,87.8%,and 90%,respectively.
