【摘要】 污泥是污水处理厂污水处理过程中的二次产物。物理法、化学法、物化法和生物法是污水处理常用方法,这些方法都或多或少产生沉淀物、颗粒物和漂浮物等,这些废水处理过程中产生的废物统称为污泥。随着环境保护要求的提高,即使在污水处理率已经比较高的欧、美、日等工业发达国家,污泥产生量的增长趋势也很明显。因此,如何将产量大,成分复杂的污泥,经过科学处理后,使其无害化、资源化,已成为我国乃至全世界环境界广泛关注的课题之一。更多还原

【Abstract】 Sludge was the secondary product in the process of sewage treatment plant sewage treatment.Physical method,chemical method,chemical method and biological method were commonly used wastewater treatment method,these methods were more or less sediment,particles and debris,etc.,these were collectively referred to as wastewater treatment process of waste sludge.With the improvement of environmental protection requirements,even in the sewage treatment had higher Europe,America,Japan and other developed countries,the growth trend of sludge production was also obvious.Therefore,how to output big,complicated composition of the sludge,after dealing with the science,make it harmless and recycling,environmental industry had become our country and the world wide attention of one of the topics.更多还原
