Municipal sludge is produced in large amounts and is difficult to treat. Incineration is the most direct and thorough treatment method. In order to study the feasibility of sintering for municipal sludge treatment, the municipal sludge reforming process was studied under high-temperature oxidation conditions. The results showed that the sludge reforming process could be divided into four stages: the precipitation and evaporation of adsorbed water, the precipitation and combustion of the volatile, the combustion of the residual volatile and solid carbon, and the decomposition of salts and the melting of sludge. An increase in the heating rate resulted in more intense sludge combustion and improved the sludge reaction capacity and combustion performance. After burning at 1300 °C, Si, Ca, Mg, Al, K, Na, and Cu formed new phases and entered the slag. 75% of P remained in the slag. 80% of the S formed SO₂ and entered the flue gas. Cl formed gaseous chlorides like HCl upon combustion and entered the flue gas. As sintering is a feasible method for treating municipal sludge, care must be taken to limit the amount of P that ends up in the ore.

城市污泥产生量大，处理难度大。焚烧是最直接彻底的处理方法。为研究烧结处理城市污泥的可行性，对高温氧化条件下的城市污泥重整工艺进行了研究。结果表明，污泥重整过程可分为吸附水的沉淀和蒸发、挥发分的沉淀和燃烧、残留挥发分和固体碳的燃烧、盐类的分解和熔化四个阶段。污泥。加热速率的增加导致更强烈的污泥燃烧并提高污泥反应能力和燃烧性能。1300℃烧成后，Si、Ca、Mg、Al、K、Na、Cu形成新相进入炉渣。75% 的 P 留在炉渣中。80% 的 S 形成 SO₂、进入烟气。Cl在燃烧时形成气态氯化物如HCl并进入烟道气。由于烧结是处理城市污泥的一种可行方法，因此必须注意限制最终进入矿石的 P 量。
