The invention provides a preparation method of a ceramsite brick. The preparation method comprises the following steps: S1, reacting deionized water, maleic acid, 2-pyrrolidone, tetradecyl dimethyl benzyl ammonium chloride, chitosan, absolute ethyl alcohol and ammonium persulfate to obtain an auxiliary agent A; S2, mixing, stirring, dewatering and drying sludge and an auxiliary A, and obtaining a dried sludge material; S3, carrying out dry distillation, iron removal and stone removal on the dried sludge material, and screening to obtain sludge granules; S4, performing high-temperature treatment on the sludge granules, and screening to obtain sludge powder; S5, reacting absolute ethyl alcohol, oleic acid and n-propylamine to obtain an auxiliary agent B; S6, mixing the sludge powder, an auxiliary agent B, coal gangue and water, uniformly performing stirring to obtain slurry, carrying out compression molding on the slurry to obtain ceramsite green bricks, drying the ceramsite green bricks, and transferring the dried ceramsite green bricks into an autoclave for autoclaving to obtain the ceramsite bricks. The ceramsite brick prepared by the invention has relatively good mechanical properties and water permeability.
本发明提供了一种陶粒砖的制备方法，包括以下步骤：S1.将去离子水、马来酸、2‑吡咯烷酮、十四烷基二甲基苄基氯化铵、壳聚糖、无水乙醇、过硫酸铵反应得到助剂A；S2.将污泥、助剂A混合、搅拌、脱水、烘干得到烘干污泥料；S3.将烘干污泥料干馏、除铁、除石后筛分得到污泥粒料；S4.将污泥粒料高温处理、筛分得到污泥粉料；S5.将无水乙醇、油酸、正丙胺反应得到助剂B；S6.将污泥粉料、助剂B、煤矸石、水混合，搅拌均匀后得到浆料，将浆料压制成型得到陶粒砖坯，将陶粒砖坯烘干后转入蒸压釜中蒸压得到陶粒砖。本发明制备得到的陶粒砖具有较好的力学性能和透水性。
