摘要
为确定金华市城市污水处理厂污泥资源化利用途径,对金华市某污水处理厂的脱水污泥进行了采样和成分分析。结果表明,所有污泥为中性,pH 6.89,含水率较高75%;污泥中有机质、氮、磷、钾含量丰富;污泥中重金属的含量较低,均符合国家农用污泥中污染物控制标准。以此为基础对污泥的农用价值及其应用前景作了分析和展望。
In order to propose an effective method for the reclamation of sewage sludge in Jinhua city, dewater sewage sludges from the typieal wastewater treatment plants were sampled and analysed. The results show that all sludge samples are alkalescent with a pH value 6. 89, and have a moisture content 75%. The samples have plenty of organic matter, N, P, K, and the heavy metals are relatively low in content and are up to the Control Standards for Pollutants in Sludges from Agricultural Use （China）. Basie quality has been analyzed and agricultural value of sludge from wastewater plant in Jinhua was forecasted.
