Construction wastes have attracted more and more public attention with the development of the city construction. On the basis of summarizing the existing slurry treatment technologies in relevant area, a new slurry treatment process is proposed according to the characteristics of waste bored pile slurry. Three steps included in this process: slurry purification, flocculation and pressure filtration. A practical application is used to demonstrate the feasibility of this process. The results show that the slurry is disposed without pollution, achieving zero discharge of pollutants.
