Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
As shown in fig. 1 and 2, the utility model provides a landfill leachate treatment system, including reservoir 1, valve well 2 and waste fitting discharging, be connected with leachate collection pipe 13 on the 1 inner wall of reservoir, leachate collection pipe 13 is terminal to extend to in the landfill, and waste fitting discharging holds in valve well 2, and waste fitting discharging includes stealthily dirty pump 3, and reservoir 1 top is equipped with access door A11, installs supporting rail 12 on the 1 inner wall of reservoir, and stealthily dirty pump 3 can slide in or roll-off reservoir 1 along supporting rail 12. A sump 4 is provided in the storage tank 1, one end of the support rail 12 is close to the sump 4, and the other end of the support rail 12 is close to the access door a 11. The sump 4 is arranged at the bottom corner of the storage pool 1. The support rail 12 is arranged in a vertical direction along its length. By adopting the technical scheme of the utility model, when the submersible sewage pump 3 needs to be overhauled, an maintainer can slide the submersible sewage pump 3 up and down along the supporting guide rail 12 by using smaller thrust to finish the operation of sinking the submersible sewage pump 3 into the sump 4 or taking the submersible sewage pump 3 out of the sump 4, thereby providing convenience for the overhauling operation, reducing the difficulty of the loading and unloading operation of the submersible sewage pump 3 and lightening the labor intensity; because the leachate has corrosivity, be equipped with the sump pit in the reservoir, when transferring the stealthily dirty pump to the sump pit in through the supporting guide rail, stealthily dirty pump arranges below whole reservoir bottom surface to can thoroughly extract the leachate in the reservoir totally, when piling up the leachate in the reservoir, stealthily dirty pump and waste fitting discharging hold in the valve well, and keep away from the leachate, can prevent that the leachate from causing the corruption to waste fitting discharging, stealthily dirty pump, extension stealthily dirty pump and waste fitting discharging's life.
In addition, the submersible sewage pump can be provided with two submersible sewage pumps, one submersible sewage pump is used as main equipment, and the other submersible sewage pump is used as standby equipment, so that at least one submersible sewage pump can work normally, and leachate is pumped out of the storage pool in time.
In addition, waste fitting discharging still includes electric butterfly valve 5 and check valve 6, and the export of stealthily dirty pump 3 is connected through input sleeve 7 with electric butterfly valve 5 entry, and electric butterfly valve 5 export is connected through transfer sleeve 8 with check valve 6 entry, and 6 exit linkage of check valve have output sleeve 9, and the end of output sleeve 9 extends to outside the valve well 2, and stealthily dirty pump 3 control end, electric butterfly valve 5 control end are respectively through wire and 10 electric connection of controller, and controller 10 is installed on the 2 outer walls of valve well. The transfer sleeve 8 is a flexible hose. When the submersible sewage pump 3 is lowered into the storage pool 1 to operate, the submersible sewage pump 3 can generate great vibration, the transfer sleeve 8 is a flexible hose which can be stretched, vibration energy from the submersible sewage pump 3 can be absorbed, the influence of vibration on the output sleeve 9 is reduced, and leachate can be accurately output to a transport vehicle.
Further, still be connected with leachate collection pipe 13 on the storage pond 1 outer wall, leachate collection pipe 13 end extends to in the landfill, installs filter screen 14 in leachate collection pipe 13. The leachate entering the storage pool 1 is all liquid, so that the leachate collection pipe 13 is prevented from being blocked. In addition, the storage pool 1 is buried in the ground soil layer, the top surface of the storage pool 1 is flush with the ground, the leachate collection pipe 13 is arranged below the ground soil layer, and the distance between the leachate collection pipe and the ground surface is not less than 800 mm.
In addition, the top of the valve well 2 is provided with an access door B15. The valve well 2 is buried in the ground soil layer. Therefore, the maintenance personnel can enter the valve well 2 through the maintenance door B15 to maintain various electromechanical devices in the valve well 2 when needed, a supporting platform 16 is arranged in the valve well 2, and the electric butterfly valve 5 and the check valve 6 are fixedly arranged on the supporting platform 16. The support table 16 stably supports the electric butterfly valve 5 and the check valve 6, and can absorb part of vibration energy generated when the submersible sewage pump 3 operates, thereby reducing the influence of the vibration on the output sleeve 9 and accurately outputting the leachate to a transport vehicle.
Furthermore, the end of the output sleeve 9 is bent to form a discharge section 17, and the discharge section 17 is arranged axially in the vertical direction. When transport vehicle traveled to the discharge section 17 below of output sleeve 9 end, can be through transferring latent dirty pump 3 to storage pond 1 in back, the leachate within the extraction storage pond 1 makes the leachate transfer to transport vehicle to the convenience is transported the leachate through transport vehicle. Preferably the relative height between the discharge section 17 and the ground is not less than 2200 mm. Can meet the height requirement of most transport vehicles.
In addition, install low level gauge and high level gauge on the 1 inner wall in storage pond, low level gauge, high level gauge are respectively through wire access controller 10, still through wire and alarm electric connection. The preferred controller 10 is of the type: HS153 SP-J. Thereby make the user can conveniently monitor the liquid level of leachate in the storage pond 1, when being full of leachate in the storage pond 1, in time arrange haulage vehicle to shift leachate, when leachate extraction finishes in the storage pond 1, in time halt submersible sewage pump 3, avoid submersible sewage pump 3 idle running.
In addition, a plurality of ventilation caps 18 are arranged at the top of the storage pool 1. Thereby keeping the interior of the storage tank 1 ventilated and reducing the odor of leachate in the storage tank 1.
Adopt the technical scheme of the utility model, because the leachate has corrosivity, be equipped with the sump pit in the reservoir, the sump pit volume is obviously less than the reservoir volume, make the stealthily dirty pump that sets up in the sump pit and the chance of leachate contact reduce, thereby the corrosion rate of leachate to stealthily dirty pump surface has been slowed down, furthermore, the reservoir top is equipped with the access door, the maintainer accessible makes stealthily dirty pump slide and accomplish the loading and unloading operation to stealthily dirty pump along the supporting guide rail, the physical demands of maintainer in the loading and unloading operation has been reduced, made things convenient for the maintainer to overhaul, the valve well top also is equipped with the access door, make things convenient for the maintainer to overhaul or change electric butterfly valve, the check valve.
