摘　　要：在生物接触氧化池中采用新型组合填料对黑臭河水进行预处理,考察了预处理效果。此外,在动态培养、自然挂膜条件下,研究了不同水力停留时间对处理效果的影响,并最终确定了最佳水力停留时间为8 h。预处理结果表明,该装置启动迅速,填料容易挂膜,对水体的适应性好,对污染物的去除率高,当HRT=8 h时,对黑臭河水中COD、NH3-N、浊度的去除率分别高达53%、80%、80%,表明装填该新型组合填料的生物反应器对黑臭河水有良好的处理效果。A new type of combined bio-carrier was used in contact oxidation tank to pretreat .black odor river water, and the pretreatment effect was investigated. Moreover, the influence of different HRT on the pretreatment effect was studied under conditions of dynamic culture and natural biofilm formation, and the optimal HRT of 8 h was determined. The pretreatment results show that the unit starts quickly, has good adaptability to water body and high removal rate of pollutants, and the biofilm is easily formed. When the HRT is 8 h, the removal rates of COD, NH3 -N and turbidity are 53%, 80% and 80% respectively, which demonstrates that the bio-reactor filled with the combined bio-carrier has good treatment effect of black odor river water.
