Method for preparing landscape brick from river sludge
The invention discloses a method for preparing landscape bricks by utilizing river sludge, which comprises the following steps: step 1, preparing shale soil, sludge, medical stone, activated carbon and zeolite, and crushing and sieving the zeolite; step 2, adsorption of free harmful ions in the sludge by the medical stone; 3, carrying out ion exchange on harmful elements in the sludge by the zeolite; step 4, coating harmful elements in the sludge; according to the preparation method disclosed by the invention, by virtue of a unique raw material ratio and an innovative treatment process, the efficient raw material ratio is formed by combining the medical stone, the activated carbon, the zeolite, the shale soil and the river sludge. Through advanced crushing and mixing processes, the particle sizes of the medical stone and the zeolite are optimized, the adsorption and ion exchange efficiency of harmful ions in the sludge is improved, and the concentration of heavy metal ions is effectively reduced. Meanwhile, the harmful elements are further fixed through a chemical coating technology in the high-temperature sintering process, and the environmental safety of the product is remarkably improved.
本发明公开了一种利用河道污泥制备景观砖的方法，包括以下步骤：步骤一、配料页岩土、污泥、麦饭石、活性炭和沸石，将沸石进行粉碎、过筛；步骤二、麦饭石对污泥游离有害离子的吸附；步骤三、沸石对污泥有害元素的离子交换；步骤四、污泥有害元素的包被；步骤五、景观砖的制备，本发明通过独特的原料配比和创新的处理工艺：结合麦饭石、活性炭、沸石与页岩土和河道污泥，形成高效原料配比。通过先进的破碎和混合工艺，优化麦饭石和沸石的粒径，提高对污泥中有害离子的吸附和离子交换效率，有效降低重金属离子浓度。同时，高温烧结过程中的化学包被技术进一步固定了这些有害元素，显著提高了产品的环境安全性。
