The middle position at hole bottom is most preferably arranged in liquid collecting groove 3, and the periphery of liquid collecting groove 3 is slightly less than the periphery of bottom of pond 1,
Trench depth is greater than 350mm.
Such as, can be before overlay film when Specific construction, intermediate in bottom of pond 1 builds a wide 50cm, and the groove of depth 40cm is made
For liquid collecting groove 3.Crack cover board 4 (or there are the gaps of 1-2cm between cover board) is covered on groove, to guarantee that biogas slurry can be flowed into smoothly
Into liquid collecting groove 3.It is levelling at the position that 4 periphery of cover board is connected with bottom of pond 1, while by the gradient of bottom of pond 1 towards intercepting gutter
Slot 3, so that liquid collecting groove 3 becomes bottom of pond minimum point.It ditches simultaneously in 2 two opposite sides of pool wall and buries gas-guide tube 6, gas-guide tube 6
It is connected in lower end access liquid collecting groove 3 and with liquid collecting groove 3, upper end is connected with atmosphere.Then pool wall and bottom of pond are carried out again
Overlay film.To which in methane-generating pit work, if bottom of pond overlay film ruptures or cracks, biogas slurry, will be along bottom of pond gradient stream after cut leakage
Enter into liquid collecting groove 3, the biogas that the biogas slurry fermentation in groove generates is imported into atmosphere via the gas-guide tube communicated therewith.
Bottom of pond eardrum is efficiently solved the problems, such as from excellent, and it is dangerous to reduce using for black film methane-generating pit.
Specific embodiment 2
A method of prevent black film methane-generating pit counterdie to be bubbled, specifically before overlay film, first at 1 middle part of black film methane-generating pit bottom
Liquid collecting groove 3 is opened up, the bottom of pond gradient is made to form bottom of trench minimum point towards liquid collecting groove 3 and at liquid collecting groove 3；Then in liquid collecting
It is laid with more than two cover boards 4 on groove 3, there are gaps between adjacent cover board 4, and keep the top surface of cover board 4 and the black film on its week edge
1 flush of methane tank bottom；Gas-guide tube 6 is buried in methane-generating pit simultaneously, 6 lower end of gas-guide tube is connected with 3 top of liquid collecting groove
Logical, upper end edge pool wall 2 is protruding and communicates with atmosphere.
In addition to cover board, other component and implementation 1 are essentially identical.
The above description is only an example of the present application, is not intended to limit this application.For those skilled in the art
