【摘要】 本中试研究以炼油废水为对象,采用两级好氧处理工艺,通过添加微生物菌剂构建生物强化处理系统,考察了复合微生物菌剂、脱氮微生物菌剂处理炼油废水的效果,并与活性污泥处理系统进行了比较研究。结果表明,当进水COD、NH4+-N平均值分别为888.0、102.6mg/L时(COD、NH4+-N容积负荷为1.05和0.121kg/m3·d),出水COD、NH4+-N平均值为86.7和7.6mg/L,COD、NH4+-N平均去除率达88.12%和92.46%;与活性污泥处理系统相比较,生物强化处理系统在COD与NH4+-N的平均容积负荷分别提高了94.44%与40.70%的情况下,去除率分别提高了35.47%与59.28%,出水水质达到《污水综合排放标准GB8976-1996》一级标准。另外,与活性污泥处理系统相比较,微生物菌剂强化处理系统具有良好的耐冲击负荷性能。更多还原

【Abstract】 In the pilot-scale experiment,two-stage aeration process and bioaugmentation system were adopted in treatment of oil refinery wastewater by adding microorganism agent,the treatment effect of Compounded Microorganism Agent and Nitrogen Removal Microorganism Agent were studied,and a comparison was made with the activated sludge system.The results showed that when the average COD and NH4+-N in the influent were 888.0 and102.6 mg/L the volume loading was 1.05,0.121 kg/m3·d,the average COD and NH4+-N in the effluent was 86.7 and 7.6 mg/L,the average removal rates of COD,NH4+-N was 88.12 % and 92.46 %.Compared with the activated sludge treatment system,in bioaugmentation system,under the condition that COD and NH4+-N volume loading were increased by 94.44% and 40.70%,the average removal rates of COD,NH4+-N rose by 35.47% and 59.28% respectively,quality of effluent met the first grade of discharging standard of comprehensive wastewater discharge standard of China(GB 8978-1996),in addition,the bioaugmentation system showed good loading shock resistant performance in the study.更多还原
