固体浓度及上清液有机物对柠檬酸污泥pH缓冲容量的影响
|
摘要
本文选取柠檬酸污泥作为研究对象并与市政污泥比较,探讨了固体浓度和上清液有机物对污泥pH缓冲容量的影响.结果表明,柠檬酸污泥的pH缓冲容量(9.50 mmol·L~(-1))比市政污泥(6.61 mmol·L~(-1))高出40%以上.污泥体系的固体浓度越大或上清液中有机物物浓度越高,则污泥的pH缓冲容量越大.污泥的pH缓冲容量与污泥固体和上清液pH缓冲容量的加和并不一致,但上清液有机物均比固体浓度对污泥体系的pH缓冲容量影响更大.
The effect of solid concentration and organic matter in supernatant on the pH buffering capacity was investigated,using citric acid processed wastewater sludge and municipal wastewater sludge for comparison. The results showed that the pH buffering capacity of citric acid sludge( 9.50 mmol·L~(-1)) was about 40% more than that of municipal sludge( 6.61 mmol·L~(-1)). The higher concentration of solid and organic matter in the supernatant resulted in the increased buffering capacity of the sludge system. The buffering capacity of sludge was not consistent with the sum of solid and supernatant. The organic matter in the supernatant had more effects on the buffering capacity of sludge than the solid concentration.
