The invention relates to the technical field of comprehensive utilization of solid waste liquid and waste, in particular to a comprehensive utilization method of desulfurized gypsum waste water. The method comprises the following steps: adding desulfurized gypsum wastewater and fly ash by using a pulping stirrer, stirring for a certain time, and heating the pulping temperature to a certain temperature by using steam after the measured slurry diffusivity reaches the standard; beating the prepared slurry into a pouring and stirring tank, adding RGM concrete reinforcing agent slurry, then adding lime and aluminum powder, uniformly stirring, and pouring the slurry into a mold box; moving the mold box where the slurry is poured to a static curing room for static gas generation; after standing gas generation is finished and a green body reaches the hardness for cutting, using a cutting machine for cutting; and putting the cut building block green body into a still kettle, and carrying out steam autoclaving at a certain pressure and temperature, so as to obtain an autoclaved aerated concrete building block finished product. The invention provides a method for utilizing solid waste liquid and waste water and comprehensively utilizing desulfurized gypsum waste water for producing the autoclaved aerated concrete building blocks.
本发明涉及固废液废综合利用技术领域,尤其涉及脱硫石膏废水的综合利用方法。包括以下步骤:使用制浆搅拌器,加入脱硫石膏废水、粉煤灰,搅拌一定时间,测量浆料扩散度达到标准后,使用蒸汽将制浆温度加热到一定温度;将制备好的浆料打到浇注搅拌罐内,加入RGM混凝土增强剂浆料,再加入白灰、铝粉,搅拌均匀后,将浆料浇注到模箱内;将已经浇注浆料的模箱移动到静养间静止发气;经过静养发气结束后,坯体达到具备切割的软硬度后,使用切割机切割;将切割后的砌块坯体放入蒸压釜内,通过一定压力和温度的蒸汽蒸压后,就可制出蒸压加气混凝土砌块成品。本发明提供出一种固废液废利用、生产蒸压加气混凝土砌块的脱硫石膏废水的综合利用方法。
