摘　　要：针对沿海工业园区初期雨水含盐量较高,不利于常规生化及难以快速启动的问题,开展改性MBBR填料制备、盐度梯级驯化的研究。研究表明,采用盐度梯级驯化的反应器MBBR稳定运行在第13天完成,比其他挂膜方式快8~10 d。16S rDNA的焦磷酸测序表明R3中球衣菌属高度丰富。因此,盐度梯级驯化是高盐雨水快速启动的有希望的替代方法,使整个系统具有耐冲击、耐盐、启动快等特点,有效降低临港工业园区人工湿地冲击负荷风险。The initial rain in coastal industrial clusters has the problem of high salt content,difficult conventional biochemical process and hard to rapid start-up.In view of that,it was carried out preparation of modified MBBR filler and cascade acclimation of salinity.Results showed that this MBBR run stably on day 13,and was 8-10 d faster than the other colonization.Pyrosequencing of 16S rRNA revealed that Sphaerotilus was the predominating microbial community at level in R3.Therefore,the step-increase of inlet method is a promising alternative for the rapid start-up of saline wastewater.The whole system has the characteristics of impact resistance,salt resistance,quick start,et al,which can effectively reduce the risk of impact load on constructed wetlands in Lingang Industrial Clusters.
