Abstract:

Membrane bioreactors have been used for treating the final effluent water from chemical industry. The solutions in relation to the problems in the debugging and operation stages of membrane treatment are put forward.The effluent water COD is below 60 mg/L， and has kept stable continuously， meeting the requirements of the Jiangsu Provincial Discharge Standard of Main Water Pollutants in Chemical Industry （DB 32/939-2006）. The effluent water can be reused in circulating water systems.

Key words: wastewaterfromchemicalindustry, membranebioreactor, wastewater recycle

摘要：
