污泥减量化技术研究进展及发展趋势

Research Progress and Development Trend on Sludge Reduction Technologies

剩余污泥的大量产生是活性污泥法处理废水工艺在实现高效净水的同时存在的负面因素,剩余污泥处置制约着活性污泥的更大规模化发展。针对这一问题,涌现出了许多取得良好剩余污泥处置效率的方法。其中部分技术已经应用于实际的污水处理工艺流程中,对部分污泥处理处置技术进行了归纳,并对污泥减量化技术未来的发展方向进行了预测。

Along with the high efficiency of the bio-sludge wastewater treatment method, the excess sludge has become the negative factor. The way dealing with the excess sludge limits the large-scale development of the bio-sludge method. In order to solve this problem, many solutions have been put forward. Some of the solutions have been used in the real wastewater treatment process. This paper makes a summary about the sludge reduction methods, meanwhile forecasts the future development of the sludge reduction methods.
