【摘要】 等离子体水处理技术是近年来国内外蓬勃发展的一种深度水处理方法。本课题研制的高压脉冲放电等离子体水处理装置具有结构简单,电气参数易于调节,适应性广,维护简便,运行可靠等特点。该装置不仅与一般的电液压脉冲水处理装置不同,而且与目前采用的传统臭氧发生器水处理装置相比较可节约能耗30%以上,处理效果更佳。本文介绍了高压脉冲放电等离子体水处理技术的原理,分析了影响等离子体水处理效果的有关因素,提出了根据被处理废水量确定放电电极对数的方法以及整套装置设备的合理配置等。本实验装置分别对重庆某厂的焦化废水和某垃圾场的垃圾渗透液进行了实验研究,找出了获得一定处理效果的主要技术参数。本装置还对只经过沉淀和过滤的饮用水进行杀菌和消毒处理,实验结果表明:经15～30分钟处理后,大肠杆菌和其它微生物的杀灭率高达95%以上。通过本课题的实验研究,找出了如何确定等离子体水处理成套设备主要参数的方法。更多还原

【Abstract】 Waste water treatment technology by plasma is one of developing deep water treatment methods in domestic and foreign recently. The high voltage pulsed discharge plasma water treatment equipment is introduced. The treatment equipment has following characteristics: simple structure, the electrical parameters easy to adjust, broad adaptability, simple maintenance, reliable operation and so on. Not only this equipment is different from general electro-hydraulic impulse water treatment device, but also the energy consumption is reduced more than 30 percent than conventional ozone generator water treatment device, and the treatment effect is good. The principle of high voltage pulsed discharge plasma water treatment technology, some factors effecting water treatment effect, and the method for determining quantity of discharge electrode couples according to amount of waste water treated and reasonable configuration of complete equipment are introduced in this paper.Some plant coking waste water and a dumping site trash penetrating fluid in Chongqing are separately treated by this equipment. Main parameters for getting certain treatment effect is found. In addition, tap water which is deposited and filtered only is sterilized and disinfected by this device. The experimental results indicate that the eliminating rate of backwoods coli and other microorganism is more than 95 percent after 15 to 30 minutes treatment.In this study, the method how to determine main parameters for the plasma water treatment equipment is provided.更多还原
