Detailed Description
The present application is described in further detail below with reference to the attached drawings.
The embodiment of the application discloses concrete effluent disposal system. Referring to fig. 1, the wastewater treatment system includes a first-stage sedimentation tank 1, a second-stage sedimentation tank 2, a third-stage sedimentation tank 3, and a clarification tank 4, which are connected in sequence.
Referring to fig. 1 and 2, a first water inlet 11 and a first water outlet 12 are respectively formed on two side walls of the primary sedimentation tank 1. The wastewater cleaned by the mixer enters the primary sedimentation tank 1 from the first water inlet 11. The bottom of the first-level sedimentation tank 1 is obliquely arranged, and the inclined upper end of the first-level sedimentation tank extends to the ground so that the dredger is driven into the first-level sedimentation tank 1 to remove settled silt and gravel.
Referring to fig. 1 and 2, a first partition wall 13 is cast in the primary sedimentation tank 1. The first partition wall 13 is disposed between the first water inlet 11 and the first water outlet 12, and the height of the first partition wall 13 is higher than that of the first water outlet 12. The first partition wall 13 is cut off at a side close to the inclined upper end of the bottom of the tank for water to flow through. Thus, the waste water enters from the first water inlet 11, bypasses the first partition wall 13 and flows into the secondary sedimentation tank 2 from the first water outlet 12. The flow path of the waste water is increased, so that silt and sand are easier to settle in the primary settling tank 1.
Referring to fig. 1, a second water outlet 21 is formed between the second-stage sedimentation tank 2 and the third-stage sedimentation tank 3, and a third water outlet 31 is formed between the third-stage sedimentation tank 3 and the clarification tank 4. The heights of the first water outlet 12, the second water outlet 21 and the third water outlet 31 are sequentially reduced to ensure that water in each tank does not flow backwards. Since the heights of the first water outlet 12, the second water outlet 21, and the third water outlet 31 are sequentially reduced, the heights of the bottoms of the primary sedimentation tank 1, the secondary sedimentation tank 2, the tertiary sedimentation tank 3, and the settling tank 4 are sequentially increased, so that each tank is used for a sufficient water storage amount.
Referring to fig. 1, the two sides of the second-level sedimentation tank 2, the third-level sedimentation tank 3 and the clarification tank 4 are poured with guard edges 5, and guard rails 51 are installed on the guard edges 5 to improve the safety of workers.
Referring to fig. 1, the side wall of the guard edge 5 of the secondary sedimentation tank 2 is communicated with a ditch 22. The ditch 22 is opened on the ground for discharging the wastewater after being cleaned from the mixing tank in the mixing plant. And a second partition wall 23 is also poured in the secondary sedimentation tank 2. The second partition wall 23 is provided with an overflow port 24. By the arrangement of the second partition wall 23, sand and stones in the wastewater discharged from the ditch 22 can be effectively precipitated.
Referring to fig. 1, further, the first water outlet 12, the overflow port 24, the second water outlet 21 and the third water outlet 31 are arranged in a staggered manner, so that a flow path of wastewater can be effectively prolonged, and a precipitation effect of the wastewater is improved.
Referring to fig. 1, the guard edge 5 is provided with a mounting plate 25 straddling the secondary sedimentation tank 2, and the mounting plate 25 is fixed on the guard edge 5 through bolts. The middle part of the mounting plate 25 is fixedly provided with a sludge pumping pump 26 through bolts, so that sludge in the secondary sedimentation tank 2 can be pumped out conveniently.
Referring to fig. 1, a first water pump 32 is installed in the third-stage sedimentation tank 3, and the first water pump 32 pumps water out for cleaning the mixer truck. And a second water suction pump 41 is installed in the clarification tank 4, and precipitation is pumped out through the second water suction pump 41 and is used for stirring concrete in the stirring station. Since the wastewater contains a large amount of alkaline substances, the interior of the clarifier 4 can be neutralized by adding acidic substances.
The implementation principle of a concrete wastewater treatment system of the embodiment of the application is as follows:
the wastewater sequentially passes through a first-stage sedimentation tank 1, a second-stage sedimentation tank 2, a third-stage sedimentation tank 3 and a clarification tank 4. After being precipitated by the primary sedimentation tank 1 and the secondary sedimentation tank 2, the wastewater enters the tertiary sedimentation tank 3, and water in the tertiary sedimentation tank 3 is extracted by the first water pump 32 and can be used for cleaning a mixer truck; the water in the clarification tank 4 is collected through the second suction pump 41 and can be used for the water for the concrete production in the mixing plant. And the settled sand sludge can be reused. Therefore, the waste of resources can be effectively reduced.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
