| 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 promotes the application of membrane separation to the treatment and reuse of chemical industrial wastewater. |
