Method for preparing sintering-free cement from municipal solid waste and product
The invention discloses a method for preparing sintering-free cement from municipal solid waste, which comprises the following steps: respectively weighing aluminum ash, diatomite and municipal solidwaste incineration fly ash, and mixing to obtain modified fly ash; respectively weighing sodium phosphate and the modified fly ash, and mixing to obtain alkali-doped modified fly ash; respectively weighing water and the alkali-doped modified fly ash, stirring, Meanwhile, carrying out low-temperature plasma irradiation, so as to obtain water-boiling-free mud slurry; and drying, grinding and sievingthe water-boiling-free mud to obtain the sintering-free cement prepared from the municipal solid waste. The invention also discloses the sintering-free cement prepared by the method. The minimum leaching values of Zn and Pb of the prepared sintering-free cement are far lower than the limit values of inorganic pollutants Zn and Pb in the Holland building material standard, and the content of dioxin is far lower than the limit values in the Household Refuse Landfill Pollution Control Standard (GB16889-2008).
本发明公开利用城市生活垃圾制备免烧结水泥的方法，分别称取铝灰、硅藻土、城市生活垃圾焚烧飞灰，混合，得改性飞灰；分别称取磷酸钠和改性飞灰，混合，得碱掺改性飞灰；分别称取水和碱掺改性飞灰，搅拌，同时进行低温等离子体照射，得免烧水泥浆；将免烧水泥浆烘干，研磨，过筛，得利用城市生活垃圾制备的免烧结水泥。本发明还公开了上述方法制备得到的免烧结水泥。本发明制备的免烧结水泥的Zn和Pb最小浸出值远低于荷兰建材标准中无机污染物Zn和Pb的限值，二噁英含量远低于《生活垃圾填埋场污染控制标准》（GB16889‑2008）中的限值。
