[0002] With the acceleration of urbanization development year by year, the concrete industry has developed rapidly. As a part of urban construction, concrete mixing stations will produce more wastewater and waste residue in the process of concrete production. In order to reduce sewage discharge, through the rational use of concrete mixing station wastewater and waste residue recycling technology, the residual concrete materials can be effectively recycled to achieve scientific utilization and implement environmental protection policies. Environmental protection management is not only a reflection of corporate social responsibility, but also an important way to promote the sustainable development of the concrete industry. Therefore, the "Key Technology Research on Comprehensive Treatment of Mixing Station Waste Residue" project has been established to effectively develop the comprehensive treatment technology of concrete mixing station wastewater and waste residue. By actively using this treatment technology, it can ensure that the performance of concrete materials is more stable, significantly reduce environmental pollution, and bring economic and environmental benefits.

[0003] The waste residue from concrete mixing plants is mainly composed of cement, hydration products, sand, stone, admixtures, unhydrated cementitious materials and mineral admixtures. The existing waste residue treatment generally achieves waste residue recycling through crushing, filtering, sorting, grinding and other processes. However, this process is cumbersome and has limited recycling efficiency for a large amount of concrete waste residue.
