The low-concentration organic wastewater treatment by coupling advanced ozone oxidation and biodegradation was studied experimentally.Using wastewater from a certain ethylene plant as an example,with 1.5-2 mg/L of a low ozone mass concentration and under certain conditions,the average COD_(Cr) of the effluent is less than 33 mg/L,the highest content of volatile phenyls of the effluent is 0.016 mg/L,and the average removal efficiency of sulfides and oil pollutants is 65.2% and 67.2%,respectively.And the removal...

The low-concentration organic wastewater treatment by coupling advanced ozone oxidation and biodegradation was studied experimentally.Using wastewater from a certain ethylene plant as an example,with 1.5-2 mg/L of a low ozone mass concentration and under certain conditions,the average COD_(Cr) of the effluent is less than 33 mg/L,the highest content of volatile phenyls of the effluent is 0.016 mg/L,and the average removal efficiency of sulfides and oil pollutants is 65.2% and 67.2%,respectively.And the removal efficiency of ammonia-nitrogen is above 87.9%,which is superior to the activated carbon adsorption.The results also indicate that variations of wastewater flow rate and pollutant concentration are dominant comparing to the ozone dosage,and the low ozone concentration can improve the biodegradation of pollutants without negative effects on (microorganism.)

实验研究了臭氧高级氧化-生化耦合技术处理低浓度有机污水。以某炼油厂乙烯废水为例,在低臭氧投加量1 5~2 0mg/L及其他一定条件下,出水CODCr平均不到33mg/L,石油类污染物平均去除率达到了67 2%,出水挥发酚最高质量浓度仅0 016mg/L,硫化物平均降解率为65 2%,氨氮去除率保持在87 9%以上,优于活性炭处理方法。实验还发现,低剂量臭氧投加量的影响不如废水流量及水质变化影响显著,前者既可提高有机物的可生化性,又不会对微生物产生抑制作用。
