anaerobic system with straw treatment
1. Introduction
PUXIN Household Household biogas digester system for waste treatmentis composed of a 6 or 10 m3 PUXIN biogas plant, pipe routes, gas purify devices and gas appliances or small power biogas generator.
PUXIN Household biogas digester system for waste treatmentismainly applied to farmhouse or domestic house to treat livestock waste, straw, human sewage and food waste.
2. Contrast between fixed dome and Puxin biogas plant
Contrast of the technical requirements for the builders
Items | The traditional fixed dome hydraulic biogas plant | The Puxin Biogas plant |
Airtight craft | Highly required | Not required |
Ability to understand blueprint | Highly required | Not required |
Ability to build the arch | Highly required (build by hand) | Not required (cast by mould) |
To judge and deal with gas leaking | Highly required | Required |
To judge and deal with water leaking | Highly required | Required |
Training period | About 3 month | About one week |
Period to become a proficient builder | 1-2 years | About one month |
Requirement of the people to be trained | Medium educated, strong ability to master skills | Not Educated, medium ability to master skills |
Success rate | Not 100% guaranteed | 100% guaranteed |
Contrast of the maintenance
Items | The traditional fixed dome hydraulic biogas plant | The Puxin Biogas plant |
To mend the gas leak of gas-holder | Dangerous and difficult The job is done inside the biogas digester, there is a possibility of poisoning. The leak can not be found. | Safe and easy The job is done on ground, there is no possibility of poisoning. The leak can be seen, and can be mended directly. |
To mend the water leak of the digester | Dangerous The digester’ outlet is too small that the air circulation in the digester is bad. So, there is a possibility of poisoning. | Safe The digester’s outlet is large enough that the air circulation in the digester is good. So, there is no possibility of poisoning. |
