摘要
本废水主要为调味品生产企业在生产过程中排放的生产废水。主要污染物为CODCr、SS、NH3-N、BOD5、色度等。本工程采用"物化+厌氧水解+缺氧+生物接触氧化法+脱色"工艺对该废水进行处理。工程自2011年08月投产至今,处理效果稳定,BOD5去除率大于98.3%,CODCr去除率大于96.4%,色度去除率大于93.3%,各项出水指标均可以达到相关的排放标准。
Case wastewater mainly an enterprises in the production process emissions.The main pollutants are CODCr,SS,NH3-N,BOD5,chroma.The project adopts ＂technology ＋ anaerobic hydrolysis ＋ anoxic ＋ biological contact oxidation ＋ decolorization＂ treating the wastewater.Engineering since 2011 08 months has been put into operation,stable treatment effect,the removal rate of BOD5 is greater than 98.3 %,the removal rate of CODCr is greater than 96.4 %,the chroma removal rate is greater than 93.3 %,the effluent can reach the emission standard.
