摘　　要：The implementation of the European WFD （water framework directive） requires IWRM （integrated water resource management）, an important tool in managing available water resources in the presence of emerging constraints. Pressures caused by variability in water supply cycles, droughts, pollution, industrialization, increasing domestic and commercial demand, inadequate infrastructure, intense urbanization and population growth, and decrepit distribution networks have led to the increasing exploitation of industrial wastewater. Most industrial process has some negative impacts on the environment especially on a catchment scale i.e. water, air and soil quality. In the context of water resources and environmental protection measures, the term ＂sustainable development＂, a development that is compatible with the future gains and environmental protection, is regulated more and more by law. To comply with these emission-based limit values, so-called ＂end-of-pipe-techniques＂ are used. Experimental results show CBT （continuous biological treatment） processes present secondary measures to purify highly contaminated industrial wastewater.
