[0052] The application also provides an environment-friendly treatment method for concrete waste slurry, comprising the following steps:

[0053] S1, the concrete waste slurry is transported to the top of the second vibrating screen 6 through the feeding pipe 10 by the external pump body, and the vibration motor 9 is started to drive the first vibrating screen 4 and the second vibrating screen 6 to vibrate, so that the sand and stones in the concrete are filtered, and water and stones are separated;

[0054] S2, the mud filtered by the second vibrating screen 6 falls into the inside of the first liquid storage bin 11 and reacts with the active sludge in the inside of the first liquid storage bin 11, at this time, the aeration pump 20 is started to air outlet to the inside of the first liquid storage bin 11 through the first aeration pipe 21, so as to promote the activity of aerobic organisms and improve the purification effect;

[0058] Working principle:

[0059] In the working process, the external pump body delivers the concrete waste slurry to the top of the second vibrating screen 6 through the feeding pipe 10, and the vibration motor 9 is started to drive the first vibrating screen 4 and the second vibrating screen 6 to vibrate, so as to filter the sand and stone in the concrete and realize water and stone separation. At this time, the mud filtered by the second vibrating screen 6 falls into the inside of the first liquid storage bin 11 and reacts with the active sludge in the inside of the first liquid storage bin 11 to purify. At this time, the aeration pump 20 is started to blow air into the inside of the first liquid storage bin 11 through the first aeration pipe 21 to promote the activity of aerobic organisms and improve the purification effect. Due to the curved arrangement of the first aeration pipe 21, the aeration pump 20 can also backflush the mud sinking to the bottom of the first liquid storage bin 11 during the working process to avoid the mud sinking to the bottom and affecting the purification effect. At the same time, it can drive the push fixed block 26 to rotate to make the acidic substances spread faster in the inside of the first liquid storage bin 11 to improve the dynamic control effect;

[0060] At the same time of reaction, the slurry pump 13 is used to extract the sludge in the inside of the first liquid storage bin 11 to enter the tangential inlet of the cyclone 15 to separate the waste slurry through the cyclone 15 to realize solid-liquid separation. The waste slurry with particles falls into the top surface of the first vibrating screen 4 through the guide block 19 to be dehydrated and screened out. The separated mud flows into the inside of the second liquid storage bin 17 through the second communication pipe 16, and then flows back to the inside of the first liquid storage bin 11 through the liquid supplement pipe 23 to be purified again to complete the internal circulation. The separated mud flows back to the first liquid storage bin 11 through the liquid supplement pipe 23 to be purified again to realize the recycling treatment of the waste slurry, avoid one-time discharge, reduce the consumption of reagents and water resources, and maintain the concentration of active substances in the reaction system stable to improve the purification effect;

[0061] At the same time of purifying the concrete waste slurry, due to the alkalinity of the mud of the concrete, some sensitive bacteria in the active sludge will be inhibited or even die in the purification process due to the alkaline characteristics of the waste slurry, which will reduce the degradation efficiency of pollutants. At this time, the acidic substances in the inside of the sealing ball 25 flow out due to the shrinkage of the hydrogel 30 in the alkaline environment in the inside of the first liquid storage bin 11, so as to neutralize the alkaline environment in the inside of the first liquid storage bin 11. Conversely, the hydrogel 30 is pushed out to drive the third flow resistance plate 28 to seal the bottom of the sealing ball 25, so as to reduce the acidic annulus in the inside of the purification block 2 to make it in the suitable reaction environment of the active sludge. Through dynamic adjustment, the risk of sludge aging and disintegration is reduced, and the system treatment capacity is maintained.

[0062] The excess liquid is discharged outward through the discharge pipe 18. After being discharged, it can still be extracted into the inside of the first liquid storage bin 11 through the external body for multiple cleaning to realize external circulation to improve the environmental protection treatment of the waste slurry.

5. The environmentally friendly treatment device for waste concrete slurry according to claim 4, characterized in that: The aeration assembly comprises a first aeration pipe (21), the first aeration pipe (21) being fixedly connected to the output end of the aeration pump (20), a second aeration pipe (22) being fixedly connected to one side of the first aeration pipe (21), the second aeration pipe (22) being connected to the first aeration pipe (21), and the farthest end of the first aeration pipe (21) being bent.

6. The environmentally friendly treatment device for waste concrete slurry according to claim 5, characterized in that: The second aeration pipe (22) is tilted and corresponds to the side surface of the second baffle (27) after being tilted. After the gas is discharged, the second aeration pipe (22) drives the fixed block (26) to rotate so as to better diffuse the acid inside the first liquid storage tank (11).

7. The method for treating waste concrete slurry according to any one of claims 4 to 6, characterized in that: The following steps are involved: S1, the external pump body transports the waste concrete slurry to the top of the second vibrating screen (6) through the feed pipe (10), and starts the vibration motor (9) to drive the first vibrating screen (4) and the second vibrating screen (6) to vibrate, thereby filtering the sand and gravel in the concrete and achieving water-stone separation; S2, the slurry filtered by the second vibrating screen (6) falls into the interior of the first liquid storage bin (11), reacts with the active sludge inside the first liquid storage bin (11) for purification, and at this time the aeration pump (20) starts to discharge air into the interior of the first liquid storage bin (11) through the first aeration pipe (21), so as to promote aerobic biological activity and enhance the purification effect; S3. During the purification process, due to the alkaline properties of the sludge, some sensitive bacteria in the activated sludge will be inhibited or even die, resulting in a decrease in the pollutant degradation efficiency. At this time, since the interior of the first liquid storage tank (11) is an alkaline environment, the hydrogel (30) shrinks, causing the acidic substances in the sealing ball (25) to flow out, thereby neutralizing the alkaline environment inside the first liquid storage tank (11). Conversely, the hydrogel (30) pushes out and drives the third baffle (28) to seal the bottom of the sealing ball (25), thereby reducing the acidic environment inside the purification block (2), making it in a suitable reaction environment for the activated sludge; S4. During the reaction, the sludge in the first liquid storage bin (11) is pumped out through the slurry pump (13) and enters the tangential feed port of the cyclone (15). The waste slurry is sorted through the cyclone (15) to perform solid-liquid separation. The waste slurry with particles falls onto the top surface of the first vibrating screen (4) through the guide block (19) for dehydration and screening. The separated slurry enters the interior of the second liquid storage bin (17) through the second connecting pipe (16), and then flows back to the interior of the first liquid storage bin (11) through the liquid replenishing pipe (23) for secondary purification, completing the internal circulation. When the water level in the first liquid storage bin (11) reaches a certain height, the buoyancy of the water flow will push the fixed block (26) and the sealing ball (25) out to seal the positioning column (24); S5. Excess liquid is discharged outward through the discharge pipe (18). After being discharged, it is still pumped into the first liquid storage tank (11) through the external body for multiple cleanings, thereby realizing external circulation and improving the environmental protection treatment of waste pulp.
