【摘要】 针对污水处理要求，满足有机物去除，同步脱氮除磷，设计了一套一体化MBBR污水处理试验装置，采用A/A/MBBR工艺模式运行。实验以微污染河水为水源，连续稳定运行，对处理装置中水质变化及处理效果进行了分析。结果表明，河水流经三个生物反应区，其COD、NH3-N、TP值厌氧池>缺氧池>好氧池，处理后平均去除率分别为60%、27%、73%，出水达到地表水II类水质标准，为小型生活污水处理及地表黑臭水处理提供技术参考。更多还原

【Abstract】 According to the requirement of wastewater treatment, organic matter removal and simultaneous nitrogen and phosphorus removal are satisfied. A set of integrated moving bed biofilm reactors（MBBR） sewage treatment test device was designed, A/A/MBBR process mode was chosed to operate continuously and stably, and micro-polluted river water was used as water source. The water quality changes and treatment effect in the treatment devices were carried, the results showed that the river water flowed through the three bioreaction zones, its values of COD, NH₃-N, TP values followed anaerobic pool>anoxic pool>aerobic pool. The average removal rate of the treatment device was 60%, 27% and 73%, respectively.The effluent meets the surface water class II water quality standard. This device provide technical reference for small domestic sewage treatment and surface black and odorous water treatment.更多还原
