摘要
为研究超声处理对污泥消化效率的影响,笔者在大坦沙污水处理厂做了现场对比试验。所用的污泥分别为经过和未经过超声处理的污泥。试验结果显示,超声处理可以显著缩短消化罐的调试周期并提高消化效率,不同的混合比例可以使产气率提高30%~60%。
To study the effect of ultrasonic treatment on anaeroic digestion of sludge, site tests have been conducted in Datansha WWTP. The sludge samples used were ultrasonically treated and untreated respectively. The results of the test indicated that ultrasonic treatment reduced the period of starting up and improve the digestion efficiency obviously. Biogas production rate was increased by 30% - 60% with mixtures at different ratio.
