Abstract
A process for comprehensive utilization of the waste water and dregs from concrete mixing station includes separation process of slurry from sand and stone, water pool system flow path, slurry reclaiming process and electro-mechanical control system. For said water pool system, when the level of slurry flowing into slurry pool is higher than the height of overflow gate, it flows into homogenizing pool and in turn into water-clearing pool. After precipitation of solid, the water in water-clearing pool can be reused. The slurry separated by slurry-sand-stone separator is concentrated in homogenizing pool and measured for reuse. Its advantage is no discharge of waste water and dregs.
