Specific embodiment

In the following description, a large amount of concrete details are given more thoroughly to manage in order to provide to the utility model Solution.It is, however, obvious to a person skilled in the art that the utility model may not need it is one or more of these thin It saves and is carried out.In other examples, in order to avoid obscuring with the utility model, for more well known in the art Technical characteristic is not described.

In order to thoroughly understand the utility model, detailed step will be proposed in following description, it is practical to illustrate The landfill leachate of novel proposition is collected and conveying device.Obviously, the execution of the utility model is not limited to the skill of this field The specific details that art personnel are familiar with.The preferred embodiment of the utility model is described in detail as follows, however in addition to these are retouched in detail Outside stating, the utility model can also have other embodiments.

It should be understood that when the term " comprising " and/or " including " is used in this specification, indicating described in presence Feature, entirety, step, operation, element and/or component, but do not preclude the presence or addition of other one or more features, entirety, Step, operation, element, component and/or their combination.

Due to a large amount of impurity of middle carrying and silt of landfill leachate, and produced after burning power plant rubbish is fermented at present After raw percolate enters leachate collection pool, percolation liquid treating system is pumped directly to by pulsating pump.Pulsating pump generally uses The large granular impurity for being deposited on bottom of pond portion is easily pumped to follow-up system from bottom of pond portion water suction is collected by self priming pump；In addition, seeping Filtrate enter aftertreatment device it is previous as manual basket filter can be set be filtered, because impurity is more in percolate, institute It will appear the maintenance of higher-frequency time with filter.

In response to the above problems, the present invention proposes a kind of collection of landfill leachate and conveying devices, such as Fig. 1 and Fig. 2 It is shown, comprising: to be percolated liquid pool, be provided with overflow wall 4 in the diafiltration liquid pool, the diafiltration liquid pool is divided into 1 He of collecting pit Clean solution tank 7；Leachate collection pump 5, the leachate collection pump 5 are arranged in the clean solution tank 7, the leachate collection pump 5 Pipeline on be provided with self-cleaning filter 6.

Referring to Fig.1, landfill leachate provided by the utility model is collected and conveying device includes diafiltration liquid pool, the diafiltration It is provided with overflow wall 4 in liquid pool, the diafiltration liquid pool is divided into collecting pit 1 and clean solution tank 7.In one embodiment, described The depth bounds for being percolated liquid pool are 8000mm~9000mm, preferably 8500mm.

Further, as depicted in figs. 1 and 2, the bottom of the diafiltration liquid pool is provided with catch pit 3, and the overflow wall 4 passes through The catch pit 3 is so that a part of the catch pit 3 is located in the collecting pit 1 and another part is located at the clean solution tank 7 In.In one embodiment, the bottom surface of the catch pit 3 is lower than the bottom surface 400mm~600mm for being percolated liquid pool, preferably 500mm。

Further, as depicted in figs. 1 and 2, reservoir is divided into collecting pit 1 and clean solution tank 7 by the overflow wall 4, by setting Overflow wall 4 is set, can make part silt in landfill leachate and contamination precipitation in collecting pit 1, landfill leachate is through overflow wall 4 Into in clean solution tank 7.In one embodiment, the altitude range of the overflow wall is 750mm~850mm, preferably 800mm.

Illustratively, landfill leachate provided by the utility model is collected and conveying device further includes percolate ditch 2, reference Fig. 1, the percolate ditch 2 are arranged on the side wall of the collecting pit 1, so that percolate is discharged into the collecting pit 1.At one In embodiment, the percolate ditch floor height about 2000mm high compared with leachate collection pool bottom surface.

Illustratively, landfill leachate provided by the utility model is collected and conveying device further includes leachate collection pump 5, The leachate collection pump 5 is arranged in the clean solution tank 7, is provided with self-cleaning on the pipeline of the leachate collection pump 5 Filter 6.

Further, the leachate collection pump 5 is configured to be pumped to percolate in subsequent diafiltration liquid processing device, is percolated Liquid collecting pump 5 is arranged in the catch pit 3 of 7 bottom of clean solution tank, it is preferable that 5 setting of leachate collection pump exists The sidewall bottom of overflow wall 4.

Illustratively, self-cleaning filter 6 is provided on the pipeline of the leachate collection pump 5.Self-cleaning filter 6 can Directly to intercept the impurity in percolate using strainer, remove suspended matter, the particulate matter in percolate, with realize reduction turbidity, It purifies water, reduces system dirt, bacterium algae, corrosion etc. and generate, and the equipment that protection system other equipment work normally.Its work Make process are as follows: percolate enters in self-cleaning filter via water inlet, and the impurity in percolate is deposited on strainer, makes strainer Inside and outside generate pressure difference；When the pressure difference of self-cleaning filter reaches preset value, strainer is cleaned automatically, including but It is not limited to carry out soil pick-up using dirt sucking tube or drives brush cleaning strainer using motor, to realize the self-cleaning of filter.

By the way that self-cleaning filter 6 is arranged on the pipeline of leachate collection pump 5, percolate is made to enter subsequent percolate Processing unit takes a step forward filtering, to reduce the impurity in landfill leachate, has high-efficient, cost using self-cleaning filter The features such as low, avoids and is filtered the higher human cost of needs and higher maintenance frequency using manual basket filter It is secondary.In addition, being conducive to improve working environment using closed transportion percolate.
