摘要
随着我国经济的快速增长,城市化、工业化不断加快,各类污水的产生也大幅度增长。污泥作为污水处理的衍生品,随着污水处理量的增加而急剧增加。提出了采用高压深度脱水工作站对污泥进行高压深度脱水,使污泥含水率降到40%左右,并可作二次利用于肥料和燃料等。并对解决污泥处理的关键技术问题进行了讲述,该技术对行业具有一定的参考意义。
With the rapid growth of China's economy and the acceleration of urbanization and industrialization,the production of various kinds of sewage has also increased significantly.Sludge,as a derivative of sewage treatment,has increased dramatically with the increase of sewage treatment capacity.The high pressure depth dewatering station is used to dehydrate the sludge with high pressure.The water content of the sludge is reduced to about 40%,and it can be used for two times in fertilizer and fuel.The key technical problems of sludge disposal were described.The technology has certain reference significance for the industry.
