单过硫酸氢钾复合盐对剩余污泥厌氧发酵的影响
Effect of potassium peroxymonosulfate on waste activated sludge anaerobic fermentation
摘要
Abstract
In order to investigate the effect of potassium peroxymonosulfate ( PMS) on the waste ac-tivated sludge ( WAS) anaerobic fermentation, the PMS of different dose was added into the fermen-tation systems.Different indicators, such as the WAS solubilization rate, disintegration degree rate, short chain fatty acids(SCFAs), protein, polysaccharide, hydrolase, capillary suction time(CST) of WAS and volatile suspended solid ( MLVSS) concentration were analyzed in the anaerobic fer-mentation process.It is found that the appropriate PMS effectively enhances the WAS hydrolysis a-cidification function and sludge reduction.The results show that when the PMS is 0.04 to 0.08 mg/mg, the fermentation performance of WAS is the best and they have a similar hydrolytic acidifi-cation performance.However, the fermentation performance of WAS is reduced and the reagent cost is increased when the PMS is higher than 0.08 mg/mg.It is not beneficial to the fermentation sys-tem operation.At the same time, it is found that the PMS can significantly increase the proportion of acetic acid to the maximum of 75.55%, and decline the proportion of propionic acid to the minimum of 0.92%in SCFAs.关键词
