Concrete mixing plant waste slurry recycling method
The invention discloses a concrete mixing plant waste slurry recycling method. The waste slurry of the concrete mixing plant is waste slurry water left after sandstone aggregate in waste slag generated after cleaning of concrete equipment and a mixer truck in the concrete production process is recycled through a sandstone separator. According to the invention, the waste slurry is prepared into a mud cake with a water content of 10-40% through precipitation and filter pressing processes; the mud cake is prepared into non-plastic hard particles with the particle size of 4-200 meshes through theprocedures of dispersion, powder coating and solidification, the non-plastic hard particles serve as aggregate containing a certain proportion of stone powder and are put into a concrete mixer according to the proportion to replace part of sand and mineral powder to be mixed with the aggregate, powder, additives and water, commercial concrete and concrete products are prepared, and the waste material is changed into things of value. The problem in the prior art that the waste slurry of the concrete mixing plant serves as solid waste to be buried to pollute the environment is solved and the problem that additional environmental protection problems can be generated during brick manufacturing except for investment equipment and places for manufacturing cement bricks, and achieves the purposeof protecting the environment.
一种混凝土搅拌站废浆回收处理利用方法。所述混凝土搅拌站废浆是混凝土生产过程中，混凝土设备、搅拌车清洗后产生的废渣，经过砂石分离机将砂石骨料回收后余下的废浆水。本发明通过沉淀、压滤工序把废浆制成含水量10～40％的泥饼，所述泥饼经过分散、粉裹、凝固工序制成无塑性的坚硬颗粒，颗粒径度在4～200目之间，作为含有一定比例石粉的骨料，按配比投入到混凝土搅拌机，替代部分砂、矿石粉与骨料、粉料、外加剂、水混合在一起，制成商品混凝土、混凝土制品，变废为宝。解决了现有技术混凝土搅拌站废浆作为固体废弃物填埋污染环境的问题；制作水泥砖除了需要投资设备及场地外，制砖还会产生额外的环保问题，达到保护环境的目的。
