Pig farm biogas tank and septic tank are two different facilities, and their differences and functions are as follows:
1. Differences: 1Structure & Function: A biogas digester is a specially designed fermentation unit that converts organic waste into biogas (methane) and biogas slurry through anaerobic fermentation technology. The septic tank is a relatively simple sedimentation and treatment facility, which is mainly used for sedimentation and preliminary treatment of fecal wastewater.
2.Treatment capacity: The digester has a higher processing capacity and is able to process more organic waste, and the biogas produced can be used for energy use, reducing dependence on fossil fuels. The treatment capacity of septic tanks is relatively small, and it is mainly used for the preliminary treatment of fecal sewage.
3.Mode of operation: The digester needs to be fed continuously and maintained at a certain temperature and pH to maintain the fermentation process. Septic tanks are relatively simple and only need to be cleaned and drained regularly.
Second, the role: 1Environmental protection: The biogas digester can reduce the impact of harmful substances in fecal sewage on the environment and reduce the pollution of soil and water bodies. Septic tanks can reduce the environmental impact of fecal wastewater, but they need to be treated later to meet discharge standards.
2.Energy utilization: The biogas produced by the biogas digester can be used for power generation, heating and other energy utilization to improve the energy self-sufficiency rate. The biogas produced by septic tanks can also be used for small energy uses such as cooking.
3.Agricultural waste utilization: The biogas digester can treat agricultural waste, such as crop straw, livestock and poultry manure, etc., and promote the resource utilization of waste. Septic tanks, on the other hand, do not have the capacity to process agricultural waste.
In summary, there are significant differences in structure and function between pig farm biogas tank and septic tank, and the biogas tank has greater advantages in terms of treatment capacity and environmental protection and energy utilization. In practice, the right facility can be selected depending on the size and processing needs of the pig farm.
