Abstract

As main methods for the degradation of liquor-making industry wastewater, biochemical treatments are mature and stable. However, there are still many technical problems in the process of wastewater treatment, such as low utilization of organic resources, anaerobic stage release of toxic gases, defection of traditional flocculant, limitation of microbialflocculant, large yield of sludge and difficult processing technologies. The design of the research adopts the internal circulation anaerobic reactor, anaerobic anoxic oxic and membrane bioreactor technology to treat the winery wastewater produced by Qingbaijiang district wanyi wine factory in Chengdu. The test results show that the process has a favorable effect toward the removing of COD, BOD₅, SS and TN. The discharge wastewater index can reach the standard of water pollutants emission limits in fermented alcohol and liquor industry water pollutant discharge standards(GB27631-2011). In addition, the process have lots of advantages such as high volumetric load, strong capability of resisting impact, economical efficiency, running stability and less land requirement. The success of such combined technology will be beneficial to the sustainable development of the liquor-making industry.
