The disposal of sewage sludge from municipal waste water treatment plants is suffering from raising costs. The gasification is an alternative way of treatment, which can reduce the amount of solid residues that must be disposed from a water treatment plant. The produced gas can be used very flexible to produce electrical energy, to burn it very cleanly or to use it for upgrading. The gasification in the fluidised bed and the gas cleaning with the granular bed filter has shown successful operation. A demonstration plant in Balingen was set up in 2002 and rebuilt to a larger throughput in 2010. As a next step a demonstration plant was built in Mannheim and is now at the end of the commissioning phase. Nowadays the product gas is blended with biogas from sludge fermentation and utilized in a gas engine or combustion chamber to produce heat. In the future the process control for a maximized efficiency and the removal of organic and inorganic impurities in the gas will be further improved.
城市污水处理厂的污泥处理费用不断增加。气化是一种替代处理方法，可以减少必须从水处理厂处理的固体残留物的数量。产生的气体可以非常灵活地用于发电，非常清洁地燃烧，或用于升级。流化床气化和颗粒床过滤器的气体净化已显示出成功的运行。2002 年在巴灵根建立了一个示范工厂，并于 2010 年扩大了产能。作为下一步，在曼海姆建立了一个示范工厂，目前处于调试阶段的末期。如今，产品气体与来自污泥发酵的沼气混合，并在燃气发动机或燃烧室中使用，以产生热量。未来，将进一步改进工艺控制，以最大限度地提高效率，并去除气体中的有机和无机杂质。
