[0028] A concrete wastewater treatment system comprises a raw slurry tank 1 and a floating water tank 2. A first partition 3 is fixedly connected between the raw slurry tank 1 and the floating water tank 2, and a first water guide hole 31 is formed in the first partition 3, the first water guide hole 31 being close to the upper edge of the first partition 3. When the mixing tank, mixing building and mixing truck are washed, the generated mud and sand are poured into the raw slurry tank 1.

[0029] A silicate high-alkali waste slurry activator modifier is injected into an activator tank 4. The activator tank 4 is connected with a treatment tank 10 through a main water pump 41. The raw slurry tank 1 is connected with the treatment tank 10 through a first water pump 51. The floating water tank 2 is connected with the raw slurry tank 1 through a second water pump 52. A concrete concentration sensor 11 is connected in the raw slurry tank 1, and the concrete concentration sensor 11 is electrically connected with the first water pump 51.

[0030] The floating water tank 2 is located between a clean water tank 6 and the raw slurry tank 1. A second partition 7 is connected between the clean water tank 6 and the floating water tank 2, and a second water guide hole 71 is formed in the second partition 7, the horizontal height of the second water guide hole 71 being lower than that of the first water guide hole 31.

[0031] When the mixing tank, mixing building and mixing truck are washed, the generated mud and sand are poured into the raw slurry tank 1, and the amount of mud and water in the raw slurry tank 1 increases. A large amount of water and a small amount of mud pass through the first water guide hole 31 and are injected into the floating water tank 2. Subsequently, a large amount of water is injected from the floating water tank 2 along the second water guide hole 71 into the clean water tank 6, and clean water is obtained in the clean water tank 6. At this time, the clean water can be used to wash the mixing truck.

[0032] The clean water tank 6 is connected with the raw slurry tank 1 through a third water pump 8.
