1. Site selection and planning.
Choose a suitable site as the base of the biogas digester, which should have convenient transportation, sufficient water sources, and stable geological structure. At the same time, according to the scale of the pig farm and the amount of waste generated, the area and layout of the biogas digester should be reasonably planned.
2. Infrastructure.
1.Excavation and construction of the digester: excavation of the earthworks of the digester according to the designed dimensions. Take care to maintain the moisture of the soil and avoid collapse.
2.Bedding laying: A layer of impermeable membrane is laid at the bottom of the digester to prevent waste leakage. At the same time, crushed stone and sand are laid on the membrane to enhance the load-bearing capacity.
3.Construction of drainage systems: Drainage ditches are placed around the digester to ensure that waste does not accumulate water.
3. Equipment installation.
1.Inlet: Install an inlet to dispose of the waste from the farm into the digester.
2.Fermenter: Select the appropriate fermentation tank material and specification according to the need, and install it in place.
3.Piping system: Connecting the biogas digester with purification equipment, combustion equipment, etc., to ensure the smooth conversion of waste.
Fourth, waste input.
Waste from pig farms (e.g. manure, feed residues, etc.) is put into the digester, taking care to control the amount and frequency of inputs so as not to affect the fermentation process.
5. Daily management.
1.Regular inspection: Regularly check the operation of the biogas digester, and deal with it in time if any abnormalities are found.
2.Maintenance: Regularly maintain the biogas digester to ensure its normal operation.
3.Waste monitoring: Monitor the fermentation of waste in the digester to ensure that it is achieving the desired results.
Sixth, environmental benefits.
The construction of the pig farm biogas digester can not only effectively reduce the pollution problem of waste, but also produce clean energy - biogas, which brings considerable environmental benefits to the pig farm. At the same time, biogas residue and biogas slurry are also good organic fertilizers, which help to improve the yield and quality of crops.
Summary: The construction method of the pig farm biogas digester is relatively simple, as long as the above steps are followed, good environmental protection results can be achieved. During the construction process, we need to pay attention to issues such as site selection and planning, infrastructure construction, equipment installation, waste input, and daily management. At the same time, we should also be aware of the environmental benefits brought by the biogas digester and contribute to our ecological environment. I hope that the introduction of this article can provide you with some useful references, so that you can pay more attention to environmental protection in the development of the aquaculture industry.
