Method for synergistically preparing environmental function material from multi-source solid waste
The invention relates to the technical field of recycling treatment of municipal solid waste, in particular to a method for synergistically preparing an environmental functional material from multi-source solid waste. The method comprises the following steps: mixing the multi-source solid waste and functional auxiliary materials, adding water, successively conducting pulping, crushing and cutting to form slurry with a uniform particle size; carrying out secondary mixing on the obtained slurry and agricultural and forestry organic waste, and then carrying out extrusion granulation; drying an oversize product to reduce a moisture content to a required value, and then firing the oversize product; and after firing is completed, carrying out cooling to obtain the environmental functional material, wherein the multi-source solid waste comprises river and lake bottom mud, municipal sludge, tailing sand, construction muck and fly ash, and the agriculture and forestry organic waste is at least one selected from corn straw, rice straw, reed stem and peanut shell. According to the invention, through mechanical force activation, endogenous self-supporting sintering and anoxic pyrolysis, the inorganic-organic hybrid environmental functional material system with a spherical and connectivity pore structure is established.
本发明涉及城市固体废弃物资源化处置的技术领域，具体涉及一种多源固废协同制备环境功能材料的方法，包括以下步骤：将多源固废与功能性辅料混合后加水进行打浆，经过破碎、切割后形成粒径均匀的浆液；将得到的浆液与农林有机废弃物进行二次混料后进行挤压造粒；将筛上物经过烘干后，使含水率降至要求后进行烧成；物料烧成结束后，进行冷却，即得到所述环境功能材料；其中，多源固废包括河湖底泥、市政污泥、尾矿砂、建筑渣土、粉煤灰；农林有机废弃物为玉米秸秆、水稻秸秆、芦苇杆、花生壳中的至少一种。本发明通过机械力活化、内源自持烧结、缺氧热解，建立球状与连通性孔隙结构的无机‑有机混杂环境功能材料体系。
