<p>The present invention discloses a method for treating sewage sludge by using circulating fluidized bed combustion. The method includes the following steps: (1) preparing the slurry of sludge with coal, by mixing fine coal and dispersant with sludge, then adding stabilizing agent; (2) burning the slurry by feeding the slurry into a circulating fluidized bed boiler which containing fluidized media of quartz sand and limestone. The preparation of the slurry also includes the steps: firstly, waste water is adsorbed/filtered by fine coal and Ca0, then others fine coal is added into the result sludge, thus the slurry is obtained.</p> |
