摘要
城市中水直接回用作电厂循环冷却水,不能满足水质标准要求,本文针对呼和浩特市污水处理厂中水水质情况,采用石灰混凝法进行了深度处理试验研究。研究表明,石灰混凝处理能有效降低浊度、碱度、硬度、有机物等的含量,并且具有运行费用低、环境污染小的优点。通过石灰混凝法对城市中水的深度处理,城市中水可以安全地回用于火力发电厂的循环冷却水系统。
Municipal sewage can not directly reuse in circulating cooling water system of Power Station because it's quality isnt satisfy the control standard of circulating cooling water in open - cycle system. The article mainly study the ability of lime coagulation treatment tech- nology to treat the effluent of xinxinban wastewater treatment plant in Huhhot. The experimental result show that lime coagulation treatment technology not only could reduce effectively total alkalinity, hardness, COD and turbidity of municipal sewage, but also have the advantages of low operating costs and small environmental impacts. By advanced treatment, municipal sewage can be reused safely.
