摘要
通过文献和标准应用情况的研究,根据10座城镇污水处理厂不同市政污泥pH、含水率、热值、氯含量、含砂量和重金属等理化指标的检测结果,分析提出燃煤电厂协同焚烧城镇污水处理厂污泥的泥质、掺烧比等关键指标,为燃煤电厂接纳市政污泥提供依据。考虑到锅炉最佳燃烧效率,掺烧污泥含水率宜低于60%,pH宜为5~12;结合污泥的理化性质、燃煤电厂实际掺烧情况及烟气污染物排放控制要求,当污泥含水率<80%时,污泥掺烧比宜控制在5%以下,当污泥含水率<60%时,污泥掺烧比宜在10%以下。
Based on literature and application of standards,combined with testing results of physicochemical properties related to pH,moisture content,calorific value,chlorine,sand and heavy metal of 10 different types of sludge samples from different urban sewage treatment plants,this paper analyzes and proposes the key indicators such as quality and blending ratio of sludge co‑incineration in coal‑fired power plants,to provide a basis for coal‑fired power plants to accept municipal sludge.Considering optimal combustion efficiency of the boiler,moisture content of the co‑fired sludge is less than 60%and pH of the co‑fired sludge is 5-12.According to the physicochemical properties of the sludge,co‑firing situation and emission requirement for flue gas pollutants of coal‑fired power plant,when moisture content of sludge is less than 80%,co‑firing ratio of sludge is less than 5%,when moisture content of sludge is less than 60%,co‑firing ratio of sludge is less than 10%.
