Embodiment Construction

[0016] Now in conjunction with the accompanying drawings the specific embodiment of the present invention is further described as follows:

[0017] From figure 1 and image 3 It can be seen that the present invention is a black-membrane biogas digester, which mainly includes: 1 soil pit 2 HDPE anti-seepage membrane 3 water inlet 4 water outlet 5 slag pumping pipe 6 biogas collection pipe 7 fermentation liquid level 8 biogas, 3 water inlets in the figure 4 water outlet 5 slag pumping pipe 6 biogas collecting pipe 7 fermentation liquid level 8 biogas, these are the same features shared by biogas digesters in my country, so they will not be described in detail. The earth pit 1 is an ordinary earth pit dug by an excavator according to requirements, and is built below the ground level or semi-underground, and the depth is determined according to the geological conditions of each place. Lay a layer of HDPE anti-seepage film 2 in the excavated earth pit, cover the upper mouth of the...

Abstract

The invention relates to a black methane biogas digester. The black methane biogas digester is an anaerobic fermentation pool. The seepage and leakage resistance of an HDPE membrane is used, an HDPE impermeable membrane is laid in a dug earth pit, a water outlet, a residue pumping pipe and a biogas collecting pipe are arranged in the pool according to anaerobic fermentation process requirements, the upper mouth of the earth pit is covered with the HDPE impervious membrane in order to seal the earth pit, and peripheral anchoring trenches are fixed to form an integral anaerobic fermentation space. Pretreated aquaculture wastewater enters the sealed space and is fermented to produce biogas, so the original high construction cost problem of the biogas digester is solved.

Description

[0001] The black-membrane biogas digester involved in the present invention is an anaerobic fermentation pond in biogas engineering. It utilizes the advantages of HDPE membrane material for anti-seepage and anti-leakage, and lays a layer of HDPE anti-seepage membrane in the dug earth pit. The oxygen fermentation process requires the installation of water inlet and outlet, slag pumping pipe and biogas collection pipe in the pool, and the upper opening of the earth pit pool is sealed with HDPE anti-seepage film, and the surrounding anchorage ditch is fixed to form an overall anaerobic fermentation space. After pre-treatment, the aquaculture sewage enters the sealed space for fermentation to produce biogas. Background technique [0002] At present, there are various kinds of biogas digesters in the construction of sewage treatment projects in my country's breeding enterprises, and the materials are not the same, all of which have the problem of high cost. Through the combination ...
