| 摘 要： | 针对城市污水厂剩余污泥浓缩过程中浓缩时间对浓缩效果、磷释放及去除的影响进行试验研究。结果表明:对已建有重力浓缩池的城市污水处理厂且污水厂处理能力存有一定富余时,可适当延长浓缩池的污泥浓缩时间,这既可大大提高浓缩池出泥的含固率,又可大部保留污泥中的含磷量,且不会对污水厂除磷产生不良影响。

| Abstract: | The effect of concentration time on sludge concentration and phosphorus release and removal were studied in the excess sludge concentration process of WWTP.For the WWTP with gravity thickener and spare treatment capacity,the concentration time of gravity thickener could be appropriately extended,which could greatly improve the solid content of sludge,retain the most of phosphorus content of sludge,and had no adverse effect on phosphorus removal in WWTP. |

| Keywords: | sludge concentration concentration time water content phosphorus release |
