流化填料在城市污水厂污泥减量中的试验

Test of Fluidized Fillers in Treatment of Sludge Reduction in Urban Sewage Plant

采用投加流化填料的方法对传统的城市污水处理厂工艺进行改造,可降低剩余污泥的产量,减少污水处理厂在污泥处理上的费用,并且在改造中不需要土建投资,不需要停水停产。本试验对老城市污水处理厂的挖潜、节能、升级改造具有实际意义。

The traditional urban sewage plant is rebuilt by taking method of fluidized fillers so as to reduce the output of remainder sludge, decrease the costs of sludge treatment in sewage treatment plant. It does not need to put investment into civil construction and to stop water supply and production in the reform. The test shows the actual significance in exploiting potentiality, saving energy and upgrading reform for old urban sewage plant.
