曝气

By pre aeration in tanyard wastewater, the effect of primary settling improves obviously.

制革采用预曝气处理后，可大大提高初沉池沉淀效果。

It is proved effective that deep well aeration biological treat propylene technology is used to treat propylene epoxide saponated sewage.

实践证明,深井曝气化处理技术处理环氧丙烷皂化行之有效的。

The experimentation inspected the infection of hydraulic load, organic load, ammonic nitrogen load, the ratio of gas and water, the height of filling to removal efficiency of COD and ammonic nitrogen.

试验以自配为试验用,考察了力负荷、进有机负荷和氨氮负荷、气比、填料层高度对曝气物滤池处理COD和氨氮效果的影响。
