摘要
介绍了反渗透技术在工业废水回用中的使用情况,分析了运行过程中易出现的问题。通过标定得出结论,当生化出水COD(化学需氧量)<50 mg/L、电导率<2 500μs/cm的条件下,反渗透产水电导率<200μs/cm、单套产水量平均值为101 m^3/h,回收率>70%。运行中存在的结垢、细菌污染、油污染等问题,应根据水质和回用水使用需求进行调节。
This paper introduced the application of the reverse osmosis technology in industrial waste water recycling,and analyzed problems easily emerged during operation.It was concluded through calibration,when biochemical treatment effluent COD(chemical oxygen demand)is<50mg/L and the conductivity is<2500μs/cm,the conductivity of reverse osmosis water is<200μs/cm,the mean value of water production capacity of single unit is101m3/h,and the recovery rate is>70%.The problems such as the existed scaling,bacterial pollution and oil pollution during operation should be regulated according to water quality and recycle water usage requirement.
