1、摘要本设计是根据某树脂厂废水处理站而进行的。该厂一直以来大力支持国家的环保政策,自觉地遵守国家的环保法律及其措施。为更好地实现废水的处理以及响应国家的政策,该厂一致决定兴建废水处理站。该厂废水处理站的设计规模为120,设计水质以业主提供的资料为准,具体为COD: BOD: SS: pH:6根据业主的要求,废水执行水污染物排放限值(DB44/26-2001)二时段一级标准,具体为COD BOD SS pH69通过对树脂生产废水的水质特性分析以及治理技术路线分析,本工程在全力遵守有关环保法律的前提下,决定采用“以化学混凝+UASB+生物接触氧化为主体”的这种目前治理树脂废水最成熟,最稳定,最经济的
2、工艺。经技术分析,此方案投资总额仅为52.841万元,废水处理成本仅为1.71元/m3完全符合该厂的经济状况。用地少、绿化好、能耗低的法理理念被很好地贯彻于整个工程之中,可谓是该类废水处理中的典范,有着榜样的作用。关键词:树脂废水,化学法纪凝处理,UASB,生物接触氧化法AbstractThe engineering design is suitable for wastewater treatment station of Huiming resin factory in SanShui.And according to the local formulate of environmenta
