摘要：采用次氯酸钠、酸性水解、臭氧氧化等处理工艺 ,提高农药杀菌剂代森锰锌废水的可生化性 ,结果表明 :当O3/CODCr为0 .0 49— 0 .0 5 6时 ,BOD/COD达 0 .3— 0 .4,生化处理CODCr去除率可提高至 70 % .臭氧与过氧化氢并用可降低臭氧投加量 。
The mancozeb exhausted water containing high concentration of ammonia nitrogen, heavy metal salts and organic bactericide is a typical toxic and non-degradable wastewater. In this paper, acidic hydrolysis, sodium hypochlorite oxidation and ozonation were adopted to increase biodegradability of wastewater. The research results show that BOD/COD enhances to 0.3—0.4 and the removal of COD Cr by biochemical treatment reaches 70% when the ratio of O 3 to COD Cr is between 0.049 and 0.056. If ozone and...
