摘要
采用厌氧 兼氧 好氧工艺处理柠檬酸生产排放的高浓度有机废水 ,处理后废水的BOD5和CODCr去除率达95 %以上 ,出水BOD5平均值为 5 8.5mg/L ,CODCr平均值为 30 4mg/L ,pH =6～ 9,达到排放标准 ,并生产沼气供生产生活使用。
An anaerobic-facultative-aerobic process has been used for the treatment of high concentration wastewater from citric acid production. More than 95% of BOD 5 and COD Cr could be removed by this process. After the treatment,average values of BOD 5、COD Cr and pH were 58.5 mg/L、304 mg/L and 6～9,respectively,which could meet discharge standard. Moreover, this process also produces methane for energy supply of production and people life.
