摘要
研究了厌氧消化工艺启动及其影响因素,并在厌氧消化稳定的情况下,对比不同投配率下,投加超声波处理剩余污泥和原泥的产气量,分析超声波处理对厌氧消化的作用效果,并分析了不同超声波污泥投配率对产气量的影响。同时试验亦研究了稳定条件下对照组和试验组NH3-N的变化情况。
The research studied the start of the anaerobic digestion and its effect. It also compared the volume of gas about the different adding ratio of the sludge which was pretreated by ultrasonic when the pilot system ran steadily. The results showed that the ultrasonic could enhance the gas output gradually. In addition the result showed that the ammonia nitrogen would be higher when the sludge was pretreated.
