Combined physicochemical and biological process was used for abrasion and painting wastewater treatment, and the design for hydrolytic acidification tank and sedimentation was improved.

同时,把二沉池排出的污泥回流至水解酸化池进行污泥减容化,还可以降低污泥的处理成本。
Simultaneously, the excess activated sludge that drained from the sediment pool returned the hydrolysis- acidification pool could be degraded, so the treatment cost of sludge could be lower.
3
介绍了制革废水处理工艺或构筑物的选择,包括调节池的选择,初沉池的选择,水解酸化池的选择等。
The choice of tannery waste water treatment technics and constructions was introduced, including adjusting pool, first deposition pool, hydrolyzation & acidification pool etc.
