| 摘 要： | 城市污水厂的污泥是指处理污水所产生的固态、半固态及液态的废弃物,含有大量的有机物、丰富的氮磷等营养物、重金属以及致病菌和病原菌等,如果不加处理任其排放,会对环境造成严重的污染。因此如何有效、经济地处理处置剩余污泥和实现污泥资源化成为中国面临的一个无法回避的问题。污泥通过减量化、稳定化、无害化可以避免二次污染,通过资源化可以进一步实现对污泥中富含的有机质、氮、磷、钾等营养元素的资源利用。

| Abstract: | Municipal wastewater treatment plant sludge refers to the solid,semi-solid and liquid wastes generated in wastewater treatment process.They contain a lot of organic matters,nutrients such as nitrogen and phosphorus,heavy metals,pathogens and bacteria.Without proper treatment,they would cause serious environmental pollutions.The problem of how to treat the residuals economically and effective recycling becomes an unavoidable issue.The nutrients in the sludge,such as organic matters,nitrogen,phosphorus and potassium can be utilized through sludge reduction,stabilization,harmless treatment to avoid secondary pollution and reclamation |
