摘要
本文通过试验研究,确认了制革污泥厌气消化处理的可能性,并根据大量的试验数据,确定了消化池的最佳投配率、投配率与产气率和有机物分解率的关系等,从而推求出污泥气的燃烧热值;与此同时,对污泥消化后脂肪酸的分解、NH_3—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。
Through experimental studies, it was affirmed that the tannery sludge being treated by anaerobic digestion is feasible. Based on the test data,the optimal loading factor to the digester,and the relationship of loading rate and gas production rate to volatile-solid reduction rate were determined, thereby, heat value of sludge gas was ascertained. 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.
