工艺设计分析

  根据项目分析,设计进入项目污水处理站的污水总量为630.5m3/d(即27m3/h)。

  浓度低的清洗废水(25m3/h,即超声波清洗废水,废水水量大、污染物浓度单一、较低)进入中水回用系统(“超滤+反渗透”,产生的浓水进入生化处理系统)处理后,中水回用系统的产水水质达到且优于《自来水水质标准,72%(即18m3/h)回用水进入项目的纯水系统处理后全部回用于生产,4%(即1m3/h)回用于研磨线,其余24%(即6m3/h)浓水收集后和高浓度污水混合处理。

  浓度较高的生产废水(即超声波药槽废水、CNC切削液、研磨废水)以及回用水浓水(6m3/h)经污水处理系统(“预处理+水解酸化+接触氧化+沉淀”)处理后,达到污水综合排放标准》(GB8978-1996)三级排放标准后达标排放(8m3/h)。
