城市污泥堆肥处理及其产业化发展中的几个关键问题

Key Problems in Municipal Sludge Composting and Its Industrialization Process

污泥堆肥处理后其有机质和N、P等营养元素可被农作物利用,促进作物增产,被认为是适合中国国情的污泥处理与处置方式。但受处理技术水平、人们的认知和可接受程度的限制以及国家政策法规、产品出路等问题的困扰,城市污泥堆肥处理及其产业化过程仍面临诸多不利因素。为从根本上解决城市污泥的处理与处置难题,城市污泥堆肥处理及其产业化过程中存在的问题必须予以解决,以加快其产业化进程。

Sludge composting is one sludge treatment and disposal method which is suitable for Chinese national conditions, because the organic matters, N, P and other nutrient elements in sludge can be used by the crops after composting. But many problems exist in the process of composting and its industrialization in China, because of the technical level of treatment, the people＇ s awareness and acceptability, the state policies and regulations and the way out for its products. The problems mentioned above must be solved in order to control the pollution of sewage sludge and speed up the development of composting industrialization.
