This design is an annual output of 100 thousand tons of beer waste water treatment process。 According to the processing scale and quality, through the analysis of selection of comparison and selection of appropriate treatment。 According to the organic content of beer waste water can be pided into 3 categories: clean waste water such as cooling water chiller, cooling wort water。 This kind of waste water not contaminated。 The cleaning waste water such as rinsing yeast water, washing water, washing water production device, this kind of waste water polluted。 The slag containing liquid waste such as wheat bad, hot and cold coagulation。 The remaining yeast, such a large number of organic waste water containing suspended solids。 The brewery waste water produced working together to discharge。 By analyzing the processing quality of knowledge of organic pollutants is higher, but the good biodegradability, it was decided to adopt the biological treatment can reach the effluent standard。 The pre-treatment section mainly uses the physical method, used to remove suspended substances in water and particulate organic matter。 Two level processing mainly by biological method, including UASB+SBR, can be effective removal of BOD, COD and so on。 The design process is determined by: beer production waste water, grille set wells and the sewage pumping station to adjust the sedimentation tank effluent of UASB reactor, SBR, ponds, sludge treatment。 Section into gravity thickener Concentrated and sent to the filter press for watering treatment。

The whole design process selection technology is mature, the effect is remarkable, reliable operation, simple management process, to ensure the effect of sewage treatment。
