| 摘 要： | 在进行城市生活污水的生物处理过程中，会产生一定量的生化污泥。在浓缩和处理剩余污泥时，所产生的含高浓度有机物的污泥上清液被回流到污水处理系统，不适当的回流会增加水处理系统的负荷并严重影响，出水的水质。实验证明，在污泥浓缩中，污泥上清液中有机物含有与浓缩温度成ｅ指数关系，与浓缩时间成小于１的指数关系。

| Abstract: | The biochemical treatment process produces an unnegligible quantity of sludge. During sludge concentration (storage) and sludge treatment a liquid containing high concentrated organic matter is produced and will be recycled to the sewage treatment system. The unsuitable recycle will increase the sewage treatment load and influence the quality of effluent from the sewage treatment plant. The test proved, during sludge concentration, the relationship between the organic matter content (CODCr) of liquid and the sludge concentration temperature, concentration duration was exponential (e and c
