【摘要】 固定化生物累托石在污水处理体系中具有较强的适应能力,温度、进水浓度、pH值等环境因素改变时,对其处理效果的影响较小,包埋体系处理生活废水的最佳运行条件是:COD浓度为400 mg/L,曝气时间为12 h,温度为20~35℃,pH值为6.5~7.5,废水与固定化生物累托石的质量比为20∶1,此时COD去除率达80.57%.更多还原

【Abstract】 After immobilization,there is little effect of environmental factors such as temperature,influent concentration,pH value on sewage.The results of the experiment shows under the condition the concentration of COD is 400 mg/L,the time of aeration is 12 h,the temperatute is 20~35℃,pH=6.5~7.5,the amount of immobilized biological rectorite to the COD is 1∶20,which indicated that the eliminating efficiency of COD is 80.57%.更多还原
