Abstract

The invention belongs to the field of concrete processing, and discloses a comprehensive utilization method for washing waste liquid of a cement tank truck. The tank washing waste liquid is recycled as tank cleaning water of the cement tank truck and production water of concrete production water equipment in a concrete factory. Multi-stage precipitation treatment is carried out on the vehicle surface cleaning waste liquid, and the clear liquid is used for diluting the cleaning waste liquid in the tank to a preset concentration. Residual clear liquid is discharged or is used as production waterof concrete production water equipment in a concrete factory. According to the method, the wastewater treatment difficulty can be effectively reduced, the cleaning water consumption is reduced, and the wastewater recycling rate is increased to the maximum extent. Meanwhile, the invention also provides a system for implementing the method. The system is simple and reasonable in structure, improvement can be conducted on the basis of a traditional vehicle washing platform, and a large amount of transformation cost does not need to be input. The method and the system are low in processing difficulty, high in processing efficiency, energy-saving and environment-friendly.
