城市生活垃圾焚烧灰渣主要由玻璃和常见矿物组成。我们研究了水和城市生活垃圾灰之间发生的主要化学反应，使用间歇式反应器。灰水溶液中主要是由可溶性盐释放的离子。X射线衍射记录了可溶性盐的溶解和至少一种次生蚀变矿物的沉淀。(1)在可溶性盐快速耗尽后，钠和钾由于离子从较难溶解的矿物和玻璃中缓慢释放而表现出接近稳态的行为。从接触每公吨灰的溶液中可以沉淀出大约10公斤的无水盐
Municipal solid waste (MSW) incineration ash is composed mainly of glasses and common minerals. We examine the dominant chemical reactions occurring between water and MSW ash using batch reactors. The ash-water solutions are dominated by ions released by soluble salts. X-ray diffraction documents the dissolution of soluble salts and the precipitation of at least one secondary alteration mineral. Three types of reactions are identified. (1) After rapid exhaustion of soluble salts, sodium and potassium exhibit nearly steady-state behavior due to the slow release of ions from less soluble minerals and glasses. Approximately 10 kg of anhydrous salts could be precipitated from a solution contacting each metric ton of ash
