The control method of the waste recycling system of the commercial concrete mixing plant according to claim 7, wherein the slurry regeneration comprises the following steps: set up the water filter at second grade grinding pot front end, the partial water source of filtration filters the water source and leads to the water supply pipe of many vehicle positions platform of unloading, adopts second grade grinding pot to grind thick liquids into the thick liquids that the granularity is less than 50 meshes and exports the thick liquids agitator tank, pours into anion polyacrylamide base polymer flocculating agent into the thick liquids agitator tank, and leading-in carries out the granulation operation in the granulator after the intensive mixing.
9. The control method of the waste recycling system for commercial concrete mixing plant according to claim 7, wherein the fine sand sewage recycling step comprises the following steps:
adopting a cyclone settling tank to divide the output slurry at the second output end of the screening device into sand and sewage again, and recycling fine sand into a sand field through the cyclone settling tank, a cyclone separation pump, a sand hopper and a sand screw in sequence; after the sewage is subjected to concentration regulation sequentially through the sewage stirring tank and the concentration regulation tank, the sewage is input into the concrete production equipment through the sewage pump and the metering system.
