| 摘 要： | 沸石的投加,降低了污泥的比阻,提高了污泥的水通量,改善了污泥膜分离效果,钝化了污水中的重金属,吸附了污水中的难降解有机物,但同时降低了污泥的体积压缩性能,改变了污泥的成分,显著增加了Si、Al、K、Na等无机组分,并对污泥的资源化途径带来了影响。 |
| 关 键 词： | 污泥处理处置 沸石 脱氮除磷 城市污水 |

| Abstract: | The pilot test result showed that, after addition of suitable content zeolite to the A/O tank,the sludge contained zeolite had a low resistance and a high membrane flux.And the heavy metals were inactivated in municipal wastewater and non degradable organic matters were adsorbed by the sludge contained zeolite,as well as the sludge compressibility was decreased.Besides, it also changed the chemical composition of the sludge and added the inorganic substances such as silicon,aluminium,potassium and sodium,and evidently influenced the way to reuse the sludge. |
| Keywords: | disposal of sludge zeolite nitrogen and phosphorus removal and municipal sewage |
