采用新型组合式生物载体在接触氧化池中对黑臭河水进行预处理，并对预处理效果进行了研究。在动态培养和自然生物膜形成条件下，研究了不同HRT对预处理效果的影响，确定了最佳HRT为8 h。预处理结果表明，该装置启动快，对水体适应性好，污染物去除率高，易形成生物膜。当HRT为8 h时，COD去除率为53%，NH3-N去除率为80%，浊度去除率为80%，说明复合载体填充生物反应器对黑臭河水有较好的处理效果。
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.
