FISH (Fluorescent In Situ Hybridization) was a rapid and simple method to detect the distribution and relative quantities of nitrifying bacteria in the floe of activated sludge.

荧光原位杂交对受锌离子污染的活性污泥微生物的检测表明，实验组硝酸细菌的分布和丰度与对照组的巨大差距是导致氨氮和亚硝酸根转化率低下的直接原因。

The formation of granular sludge is consanguineous with waterpower, and the formation is under the gravitation, flotage and shearing strength, and the diameter is affected by VOL of reactor.

颗粒污泥的形成与水力条件关系密切，颗粒污泥是在重力、浮力和阻力以及剪切力的作用下形成的，直径的大小与容积负荷有关。

In contrast, the AS sludge was composed of large floes; few free-swimming bacteria; and higher amounts of filamentous organism, ciliates, and nematodes.

The incorporation of waste tire beads at a concentration of 40 g/L into conventional activated sludge tank, led to the attachment of 50 mg/g biomass on the surface of tyre beads at steady state.

传统的活性污泥工艺中加入废弃轮胎颗粒作为生物膜载体形成复合式生物膜反应器，在颗粒浓度为40g/L时，稳定运行条件下在轮胎颗粒表面可形成约50mg/ g 的生物膜量，即在传统曝气池的2000～3000mg/L悬浮生长污泥的基础上，可增加2000mg/L的附着生物膜量。

PCBs at the beginning of the land fill were mainly composed of the 3-Cl and 5-Cl compounds. In the late of the land fill, 2-Cl compounds increased significantly. The main factor affecting the PAHs, PCBs contents were microbial degradation and transformation. Analysis of the pollutants source s indicated that PAHs in sludge were mainly derived from the waste water of refinery, coking plant, gasworks, smelt plant and pitch plant.

填埋初期污泥中PCBs主要以3-Cl和5-Cl化合物为主，填埋后期，2-Cl化合物大大增加，占总的PCBs含量的大部分影响PAHs、PCBs含量变化的主要因素是生物对PAHS的降解转化根据污泥中各污染物的含量对污染物进行源解析表明，污泥中PAHs主要来源于炼油厂、炼焦厂、煤气厂、冶炼厂和沥青厂等排放的废水。
