The invention relates to a recycling treatment method of concrete wastewater. The recycling treatment method comprises a step of preparing high-purity calcium carbonate and a step of recycling decalcified filtrate. The concrete wastewater is used as a raw material, the technological process is simple, the production cost is low, the concrete wastewater is efficiently recycled, meanwhile, environmental pollution caused by partial CO2 emission is solved, the concrete wastewater is efficiently recycled, and good environmental benefits are achieved; the purity of the product prepared by the method can reach 99.00% or above, and the product is calcite crystal form calcium carbonate and has great application value and market value. 本发明涉及一种混凝土废水的再利用处理方法，所述再利用处理方法包括制备高纯碳酸钙的步骤和回收脱钙滤液的步骤。本发明以混凝土废水为原料，其工艺流程简单、生产成本低，在高效回收利用混凝土废水的同时解决了部分CO2排放造成的环境污染，使得混凝土废水得到了高效回收利用，具有良好的环境效益；通过本发明制得的产品纯度可达99.00％以上，均为方解石晶型碳酸钙，具有极大的应用价值和市场价值。
