对经过萃取羊毛脂、厌氧发酵后的洗毛废水采用活性炭生物接触氧化法进一步处理,出水COD从620~640 mg/L降到60~100 mg/L,BOD5从410~430 mg/L降到40~70 mg/L,达到国家排放标准,如果再进一步处理,可重新用于洗毛过程。

Further treatment of washing wool effluent after extraction of lanoline and anaerobic fermentation by biological contact oxidation process has been carried out.The results show that the effluent's COD can be reduced from 620~640 mg/L to 60~100 mg/L and BOD5 from 410~430 mg/L to 40~70 mg/L.The indexes of the effluent meet the national discharge standard.The effluent could be recycled to washing wool process if being further treated.
