1.By pre aeration in tanyard wastewater, the effect of primary settling improves obviously.
制革污水采用预曝气处理后,可初沉池沉淀效果。
2.It is proved effective that deep well aeration biological treat propylene technology is used to treat propylene epoxide saponated sewage.
实践证明,深井曝气生化处理技术处理环氧丙烷皂化污水是行之有效的。
3.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.
