Meanwhile, decomposition of fatty acids after digestion, increase in NH3-N and the feasibility of use digested tannery sludge on farmland etc. were discussed as well.

与此同时，对污泥消化后脂肪酸的分解、NH3&N的提高等也进行了广泛地讨论，探讨消化后的制革污泥用于农田的可能性。

The practical operation shows that the treated water can flow back with uniform rate to the raw water distributing well and sludge cake with water content of 80% has been obtained after mechanical dewatering.

工程运行表明经处理后的生产废水能均匀回流至配水井，经机械脱水后污泥的含水率能达到80%以下。
