摘要
城市污水处理厂污泥处理处置的首要原则是污泥稳定化。对前人总结的污泥稳定化程度评价指标进行了分析,如腐殖质、植物毒素、BOD5/COD值、污泥耗氧速率和脱氢酶活性等,通过权重计算及专家打分最终确定了3个在经济、技术、环境等各方面均可行的污泥稳定化评价指标,即腐殖质、有机酸和碱性液化试验,建议以上3个指标在实践中多加应用。
The first principle of municipal sludge treatment and disposal is stabilization. The previous indexes for sludge stabilization, such as humus, plant toxins, BOD5/COD ratio, oxygen uptake rate of sludge and dehydrogenase activity were analyzed. From economic, technical and environmental consideration, humus, organic acids and alkaline liquefaction experiments were determined by weight calculation and expert estimation. It is recommended to pay more attention to the application of the above three indexes in practice.
