    摘要:

    以竹园污泥燃烧项目为依托，采取SMT方式研究磷在干污泥、炉渣和飞灰中的含量和赋存形态。成果注解，燃烧进程使炉渣和飞灰中的总磷（TP）含量比干污泥提高了2~3倍，还使此中的无机磷（IP）含量年夜幅晋升至TP总量的99%以上，在实现磷富集的同时有用晋升了磷的生物可操纵性。阐发燃烧进程对磷灰石无机磷（AP）和非磷灰石无机磷（NAIP）的影响，发觉镁离子与钙离子会与污泥中的NAIP产生反映，代替铝离子从而生成钙镁连系情势的AP；与炉渣比拟，飞灰在布袋处受CaO添加的影响，此种转化趋向更加较着，AP已跨越NAIP成为劣势形态，占IP总量的78.4%。燃烧是上海地域处置污泥的首要体例，该研究成果从养分物收受接管角度为污泥燃烧飞灰的资本化操纵供给了新思绪。

    Abstract:

    Based on Zhuyuan sludge incineration project, contents and forms of phosphorus in dry sludge, slag and fly ash were explored by using SMT method. The total phosphor����APPus (TP) contents in slag and fly ash were 2 to 3 times higher than that in dry sludge, and the inorganic phosphorus (IP) contents in slag and fly ash were increased to more than 99% of the total TP. Therefore, the phosphorus bioavailability was effectively improved while phosphorus enrichment was realized. The effects of incineration process on apatite inorganic phosphorus (AP) and non-apatite inorganic phosphorus (NAIP) were analyzed. It was found that magnesium and calcium ions reacted with NAIP in sludge, replacing aluminum ion to form calcium-magnesium binding AP. Compared with slag, this transformation trend in fly ash was more obvious because of CaO addition in bags, and the AP surpassed NAIP to become the dominant form, accounting for 78.4% of the total IP. As incineration is the main way of sludge treatment in Shanghai, the above conclusions provide a new idea for resource utilization of fly ash created in sludge incineration from the perspective of nutrient recovery.
