污泥低温碳化燃料化关键技术研究

Research on Key Technologies of Low Temperature Carbonization Fuel Sludge

我国污水处理事业近年来取得了前所未有的发展,但污水净化的同时,产生了大量污泥。污泥中含有大量病原微生物及重金属等,会对周围环境造成二次污染,威胁人类生存。如何有效地将产量巨大、成分复杂的污泥进行妥善处理处置已成为我国环境事业的重大课题。另外,我国经济迅速发展,能源需求增加,但常规能源日益供应不足,开发新能源十分紧迫。若能合理开发、利用污泥中的能源,变废为宝,不仅能解决污染问题,还利于解决我国能源短缺问题,构建资源节约型与环境友好型社会。

China's sewage treatment industry has achieved unprecedented development in recent years, but at the same time as sewage purification, a large amount of sludge is produced. The sludge contains a large number of pathogenic microorganisms and heavy metals, which will cause secondary pollution to the surrounding environment and threaten human survival. How to effectively dispose of sludge with large output and complex composition has become a major issue in China's environmental undertakings. On the other hand, China's economy is developing rapidly, energy demand is increasing, but conventional energy sources are increasingly under-supplied, and it is urgent to develop new energy sources. If we can rationally develop and utilize the energy in the sludge and turn waste into treasure, it will not only solve the pollution problem, but also help solve the problem of energy shortage in China and build a resource-saving and environment-friendly society.
