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40m3/d。

  genjubenxiangmudefeishuiqingkuanglaikan,benxiangmudegongyixuanzezhuyaocong cu、cod、lvhuawufangmianjinxingxuanze,tongshiyekaolvdiyileiwuranwuniedequchugongyi。

  浓度低的磨板酸洗废水(15m3/d,废水水量相对较大、污染物浓度单一、较低,适宜回用)与一般清洗废水(19m3/d,废水水量相对较大、污染物浓度低,适宜回用)现经过预处理和资源回收后,进入中水回用系统(“超滤+反渗透”,产生的浓水进入可以满足排放要求)处理后,中水回用系统的产水水质达到且优于回用水水质标准,61.76%(即21m3/d)回用水进入生产线,其余38.24%(即11m3/d)浓水收集后达到排放标准排放。

  浓度较高的有机废水(即4m3/d,水量小、主要污染因子为COD)以及高浓度铜、镍、氯化物废水(2m3/h,水量小、主要污染因子为Cu、Ni、Cl)经污水处理系统分别处理后,达到排放标准后达标排放(6m3/d)。
