摘要 随着国家环境保护力度的加大,国家和地方政府相继出台一系列环保加严标准,要求企业严格按照排放标准执行。兖矿国宏化工公司污水站排水COD含量30~60mg/L,总氮含量150~200mg/L,总磷含量1.5~3mg/L,远达不到标准要求。为满足国家、地方加严环境保护指标要求,解决污水处理站排水总氮超标严重、总磷、COD超标、气化灰水硬度大等问题,特研究对污水站实施提标技术改造。通过增加废水预处理、优化加药方案、增加废水接触氧化设施等,实现污水处理站排水COD<30mg/L、氨氮<5mg/L、总氮(TN)<15mg/L、总磷<0.5mg/L,达到国家最新废水排放指标要求。 With the increase of national environmental protection,national and local governments have issued a series of strict environmental protection standards,which require enterprises to strictly implement emission standards.The COD content 30~60 mg/L,the total nitrogen content 150~200 mg/L and the total phosphorus content 1.5~3 mg/L of sewage station of Yankuangguohong Chemical Company are far from the standard requirements.In order to meet the requirements of national and local environmental protection indexes,and to solve the problems of serious excess of total nitrogen,total phosphorus,COD and hardness of gasified ash water in sewage treatment stations,the technical reform of raising standards for sewage stations is studied.Through Increase the pretreatment of wastewater,optimize the dosing scheme,increase the wastewater contact oxidation facilities,etc.,realize the sewage treatment station drainage COD<30 mg/L,ammonia nitrogen<5 mg/L,total nitrogen(TN)<15 mg/L,total phosphorus<0.5 mg/L,etc.To meet the latest national wastewater discharge targets.
