摘要：
化工生产废水具有污染程度高、pH变化大、可生化性较差、并且含盐量较高的特点，为了实现废水回用的目的，采用物化预处理、水解酸化+接触氧化+超滤+反渗透相结合的处理工艺。出水回用于循环冷却水补充水，同时达到了节水治污的目标。本技术推动了膜分离技术在化工废水回用中的应用。

Abstract:
The integrated technique with biological and membrane separation processes for chemical industrial wastewater treatment and reuse is introduced. Chemical industrial wastewater is characterized by seriously polluted, low biodegradability, variable pH and high organic and high salt concentration. The physico-chemical pretreatment, biological processes like hydrolysis acidification and aerobic biological film reactor, integrated with UF and RO membrane separation are used and designed. The treatment water is reused as circulating cooling water. Water saving and controlling have been realized altogether. The technique also promotesthe application of membrane separation to the treatment and reuse of chemical industrial wastewater.
