The invention discloses a zero-discharge treatment system for solid-liquid waste of a concrete mixing plant and a treatment process of the zero-discharge treatment system, and relates to the technical field of waste treatment. Comprising a car washer and a sand-gravel separator which are sequentially arranged from top to bottom, a feeding groove of the sand-gravel separator is connected with the car washer, a discharging groove of the sand-gravel separator is connected with a feeding port of a mortar separator, a discharging groove of the mortar separator is connected with a sewage tank, and a water outlet of a sewage pump in the sewage tank is connected with the car washer. The sewage tank is also connected with a finished product discharging hopper through the stirrer; the gravel separator comprises a base embedded in the ground, the position of the car washer corresponds to the position of the base up and down, and a linear vibrating screen, a mortar separating screen and a slurry pool are sequentially arranged on the base from top to bottom. The method has the advantages that waste generated in the production process of the concrete mixing plant can be separated and then used as production raw materials, the production cost is reduced, and finally zero emission of solid-liquid waste is achieved.

    本发明公开了一种混凝土搅拌站固液废弃物零排放处理系统及其处理工艺,涉及废弃物处理技术领域。包括自上而下依次设置的洗车机和砂石分离机,砂石分离机的进料槽与洗车机相连接,砂石分离机的出料槽与砂浆分离机的进料口连接,砂浆分离机的出料槽连接污水罐,污水罐中污水泵的出水口与洗车机相连接,污水罐通过搅拌机还连接有成品放料斗;砂石分离机包括嵌入安装在地面内部的底座,洗车机的位置与底座的位置上下相对应,底座上自上而下依次设置有直线振动筛、砂浆分离筛和料浆池。本发明具有可对混凝土搅拌站在生产过程中产生的废弃物分离后用于生产原料,降低了生产成本,最终实现了固液废弃物的零排放等优点。
