城市污泥处置技术及资源化利用研究综述
摘要
随着时代的发展、经济的进步,我国城市化进程也随之加快,百姓的收入水平与消费能力也与日俱增,但伴随而来的是环境的污染以及食品安全等问题,城镇工业废水及生活污水量也日渐增多。作为污水处理过程中的附加产物,污泥中虽然含有大量的寄生虫卵、病原微生物与重金属,但其所具有的高热值与营养物质也是不容忽略的,是可以对其进行二次利用的"再生性资源"。详细地总结了当前我国常用且长效的污泥资源化处置手段,并针对实际情况给出了有效的建议,以期对相关领域有所裨益。
With the development of the times and the progress of economy,the urbanization process of our country is speeding up,and the income level and consumption capacity of the people are also increasing day by day. However,the problems of environmental pollution and food safety are accompanied,which seriously threaten people's health. In this context,urban industrial wastewater and domestic wastewater are also increasing. As an additional product in sewage treatment process,sludge contains a large number of parasite eggs,pathogenic microorganisms and heavy metals,but its high calorific value and nutrients can not be ignored. It can be used as a"regenerative resource"for its secondary utilization. In view of this,this paper summarizes in detail the commonly used and long-term sludge resource disposal methods in China,and according to the actual situation,gives effective suggestions,in order to benefit the relevant fields.
