摘　　要：为解决石油化工废水生化处理系统受到高有机污染物冲击引起的处理效果急剧下降的问题,在生化池里投加解毒剂、促生剂、活性磷和硝化菌种产品。试验结果表明:经过10 d的生物修复,生化系统CODCr去除率由受损时的35%提高到60%,系统稳定后CODCr去除率恢复到80%以上;投加硝化菌后使得二沉池出水NH3-N的质量浓度在15 mg/L以下。采用生物促生联合菌种技术能够快速修复受损的生化系统,并且快速建立硝化反应系统,提高NH3-N的去除效果。For dealing with the sharp decline of the efficiency of petrochemical wastewater biochemical treatment system caused by high concentration organic pollution impact, micatrol, bio-energizer, super phos and nitrobacteria were fed into biochemical pond. The results of the test showed that, after 10 days of bioremediation,the removal rate of CODCrby the biochemical system was improved from 35% to 60%, and even reached above80% when the operation was stable; besides, with nitrobacteria addition, the mass concentration of NH3-N in the effluent water from secondary sedimentation pond was lower than 15 mg/L. It could be seen that, using biostimulation-strains combined process could quickly remediate damaged biochemical system and establish nitrificationdenitrification reaction system, and then, heighten the removal rate of NH3-N.
