摘要
杭州某污水处理厂原设计出水执行一级A标准处理规模为14万m^(2)/d。为满足更加严格的浙江省地标要求,该污水处理厂充分利用原有处理设施的基础上,对原有设施实施提标改造。对于污水处理厂接收的工业废水,TN、COD是提标改造的重点。工程调整回流比,确保足够的回流时间,新增臭氧氧化工艺,为相类似污水处理厂的提标改造提供参考。
Designed efluent of a WWTP in Hangzhou can meet the first grade A standard,and treatment capacity is 140,000 m^(3)/d.In order to meet the more stringent requirements of landmarks in Zhejiang Province,the WWTP implement upgrading and reconstruc-tion base on existing treatment facilities.Industrial waste water is received in the WWTP,thus total nitrogen and COD are the key points of project.Reflux ratio is adjusted to ensure suffcient reflux time,and ozonation process is added to provide reference for the upgrading of similar wastewater treatment plants.
