浓缩

Concentration by micro-filtration led to the losing of the potentiator, but loss of the titer resulting from micro-filtration was less than that of centrifugalization.

微滤浓缩会引起上清液中的增效物质的损失，但微滤浓缩引起的效价损失要小于离心浓缩。

The results show that the thickening technology of excessive activated sludge by flotation has more advantages, such as good thickening effect and efficient operation. In addition, the preliminary analysis in technical economy for both methods indicates that the flotation method is better.

研究结果还表明：剩余活性污泥的气浮浓缩法相比于重力浓缩法具有浓缩效果好、运行效率高等优点，另外对两种方法的经济技术分析也表明，气浮浓缩法更具有优越性。

Given 98.3% water content of influent sludge and 54.8d of SRT, the water content for discharged sludge is around 90%, showing a better thickening effect than ordinary thickener ( water content of discharged sludge is about 97.5%~ 98%).

进泥含水率98.3%左右，污泥浓缩停留时间为54.8d，排泥含水率在90%左右，浓缩效果优于普通的浓缩池（普通重力浓缩池排泥含水率为97.5%～98%）。
