研究了不同空化状态下超声作用下对厦门 竹员 竹当 湖水、污水处理厂污水、啤酒废水及不同浓度的洗涤废水中有害物质的降解作用 ,从而探讨超声作用温度、时间、功率及 PH值变化对废水中有害物质降解的影响 .发现了一些超声作用与有害物质之间的基本关系 :超声作用对生活污水中洗涤剂和氨氮有明显的降解作用 ,并且其作用受 p H影响较大 ,降解程度随超声作用的功率 ,作用时间的增加而增加 ,随温度的提高先增高后降低 ,随起始 p H值降低而增高 .对超声作用降解有害物质的初步摸索结果 ,为进一步研究、开发新的降解途径作了必要的铺垫This experimental study is about the supersonic degradation of the injurant of the Yuandang Lake, the sewage factory and different concentrate sewage, in different cavitating conditions. The effects of the supersonic temperature, time, power and variation of pH on the degradation were investigated. It was experimentally found that there existed relationships between supersonic wave and poisons. The degradation effect of supersonic is obvious on the detergent and NH 4 N coming from the urban waste water. Furthermore, the pH of influent had pronounced effect. The power of the supersonic wave and the affecting time were also be found to have positive effect on the degradation degree. Raising temperature make the degradation degree increase, but decrease when the temperature was too high. A low pH value would be in faver of increasing the degradation degree. The present work would be helpful for development of new degradation ways
