摘要
筛选了针对甲苯、乙苯、对二甲苯、苯并噻唑和邻苯二甲酸二丁酯的高效降解菌。将这5种高效菌制成复合微生物菌剂,投加到序批式反应池中进行生物强化。比较了强化系统与非强化系统的处理效果,研究了强化投菌对系统的影响。结果表明,投加复合菌剂能够缩短系统达到稳定的时间,增强耐负荷冲击的能力,有效提高COD去除率。10%投菌量的强化系统10 h即可达到稳定出水,COD去除率最高可达96%,COD的最大耐负荷冲击能力达到1.020 kg.m-3.d-1。
Five strains were isolated for degrading five refractory biodegradation organic compounds including toluene,ethylbenzene,xylene,benzothiazole and dibutylphthalate. In order to improve the treatment effect of SBR system,the five strains were prepared into complex lively bacterial preparation（CLBP）,and were added into SBR system to carry out bioaugmentation. The difference of treatment effect of bioaugmentation system （BS） and non-bioaugmentation system （NBS） and the effect of added amount of bacteria on SBR system were researched. The results showed that adding CLBP could reduce the time for stabilization,increase the ability of resistance to shock loads, and effectively enhance the removal rate of COD. The bioaugmentation system with the added amount of 10% for 10 hours could make the amount of COD in effluent stable,the removal rate of COD could reach the max of 96% and the biggest resistence of COD to load shock reached 1. 020 kg·m^-3·d^-1.
