电液压脉冲激活黑土的实验研究

Experiment on Activation of Black Soil by Electro-hydraulic Impulse

采用电液压脉冲激活黑土,将黑土中不溶于水的大量N、P、K和丰富的有机物质变成绿色肥料,为解决目前废水处理产生的大量污泥的资源化提供了一种重要的技术途径.电液压脉冲激活黑土的试验结果表明:对于不同种类的黑土,经电液压脉冲激活后它的NH4(植物能吸收和利用的速性N)的含量增加1～4倍,水溶性有机物增加4倍,这对污泥处理有重要的参考价值.

The activation of black soil （analog the lignite） by electro-hydraulic impulse is proposed. The abundant insoluble nitrogen, phosphorus, potassium and other organic elements in black soil are activated as the green fertilizer by this way. The new method is provided for activating sludge produced by treating wastewater. For several kinds of black soil, the experiment result indicates that electro-hydraulic impulse increases the percentage of absorbable nitrogen by 1 to 4 times and the percentage of insoluble organic elements by 4 times, which is a valuable reference to sludge treatment.
