摘要
运用bloom逐步提取法以杭州和宁波两个污水处理厂的压滤污泥为研究对象,测定了污泥中总Hg及各形态Hg的含量,经分析得出污泥中汞均符合《城镇污水处理厂污泥处置农用污泥》规定的A级标准,且污泥都主要以残渣态汞存在,宁波污泥的生物有效性和潜在风险略高于杭州。
Taking the filter-pressed sludge of two sewage treatment plants in Hangzhon and Ningbo as the research object, the content of total Hg and Hg in the sludge was determined by the method of bloom sequential extraction. The results showed that mercury content in the sludge can both meet the standard A of ＂Urban Sewage Treatment Plant Sludge Disposal of Agricultural Sludge＂ and it＇s mainly in the form of sediment. Furthermore, the biological effectiveness and potential risk of N ingbo sludge is slightly higher than that of Hangzhou.
