Embodiment 1

[0021] The multifunctional earthworm breeding bed of this example is as figure 1 , figure 2 and image 3 As shown, it is surrounded by an impermeable wall 1, and there is a top cover on the wall 1. The structure from the bottom to the upper part of the wall 1 is an anti-seepage layer, an adjustment layer 2 and a breeding layer 3; the permeability coefficient of the anti-seepage layer not more than 10 -6 cm / s; the adjustment layer 2 is a pebble layer, the thickness of the pebble layer is 500-800mm, and the particle size range of the pebble is 10-80mm. The bottom of the pebble layer is arranged along the longitudinal direction of the breeding bed with a perforated drainage pipe 6 and a perforated air distribution pipe 7. One end of the perforated drainage pipe 6 It is connected with the water collection well 8 outside the wall body 1, and is water-sealed, and the other end is connected with the fan 13. The perforated drain pipe 6 also has the function of transporting odor, an...

Embodiment 2

[0026] The multifunctional earthworm breeding bed of this example is the compacted soil layer 4 except that the bottom layer of the anti-seepage layer is an anti-seepage film 5 above the compacted soil layer, and the anti-seepage film 5 is a geomembrane plus a geotextile, and all the others are the same as in the first embodiment. .

[0027] The multifunctional earthworm breeding bed of this example is not only used as a breeding facility, but also as an odor treatment facility.

Embodiment 3

[0029] The multifunctional earthworm breeding bed of this example is except that the wall-through pipe head 10 is not provided with a plug, and all the other are with embodiment one.

[0030] The multifunctional earthworm breeding bed of this example is only used as a breeding facility, and the inside of the bed body communicates with the external atmosphere, while the drain pipe communicates with the external atmosphere without water sealing.

Abstract

The invention belongs to the field of earthworm breeding and provides a multifunctional earthworm breeding bed. The earthworm breeding bed is defined by a wall (1) which prevents water seepage. An impermeable layer, an adjusting layer (2) and a breeding layer (3) are arranged in the wall (1) from bottom to top in sequence. A perforated drain pipe (6) and perforated air distribution pipes (7) are arranged at the bottom of the adjusting layer (2). The perforated drain pipe (6) is communicated with a water-collecting well (8) located outside the wall (1). The perforated air distribution pipes (7) are connected with the perforated drain pipe (6). Through-wall pipe heads (10) are arranged on the wall (1). By the adoption of the multifunctional earthworm breeding bed, the defects that in the prior art, lower soil and underground water are polluted, industrialized breeding is difficult to achieve, and foul gas is not treated are overcome, the growth environment of earthworms is greatly improved, manual controllability is improved, the pollution of percolate to lower soil is effectively reduced, and the multifunctional earthworm breeding bed can also be used as foul gas treating facilities of a sludge treatment plant.

Description

technical field [0001] The invention belongs to the field of earthworm cultivation, and in particular relates to a multifunctional earthworm cultivation bed. Background technique [0002] The earthworm breeding bed is the sludge treatment place, the earthworm growth and breeding place, and the core structure of the earthworm breeding sludge treatment technology. However, the earthworm breeding bed currently used has many disadvantages. In the process of earthworm breeding, in order to ensure the best living environment for earthworms, temperature and humidity adjustment measures such as artificial water spraying are required. Therefore, some leachate will be produced at the bottom of the culture bed, and the leachate will contain certain toxic and harmful substances. Existing earthworm culture There is no bottom anti-seepage system in the beds, and the long-term use of the breeding beds may pollute the lower soil and groundwater; at the same time, the gas circulation in the ...
