I.The characterization of
biogas digesterÂ
1. The  biogas digester of double diaphragms is made of
high-strengthened, high-elastic synthetic engineering diaphragm and
of perfect anti-acid and anti-corrosion ability. Its capacity of
absorbing the ambient heat and storing it is *0 % higher than that
of other material.
2. The biogas digester is made by adopting a technology of
combining internal digester and external protector. In this way, it
not only minimizes the possibility of doing damage to the internal
digester, prolong its life span, and also create a complete
oxygen-free room for anaerobic microorganisms to do fermentation,
which in return increases the biogas output ratio.
3. Compared with the cement biogas tank, it has the advantages as
follows:
Airproof performance
Sealant is unnecessary, for it is of excellent airproof performance
to guarantee an anaerobic fermenting situation, and is very easy to
check for leakage.
No crust
Crust is not prone to be formed,
circulating automatically under the influence of pressure and fall
to stir the fermenting material
Feed inlet and outlet
It is easy to add
material. Open the ball valve to discharge the waste.
Technicians required
It is easy to build pits. The skill of building pits is easy to
master, so there is no need to train the workers.
Maintenance
It is convenient to maintain and replace the equipments. If it is
broken, you can maintain immediately by yourself.
Safety
It is equipped with the reducer and the fire-resistant device to
keep it from exploding and free of backfire, and people won’t fall
into it.
Cost
It is about 1/3 of that of building a concrete or cement
biogas digester.
Life Span: more that ten years

III.Process flow of the biogas digester
III.Explanation for Process flow of the biogas digester
1. The daily dung-dirt through the Dung-dirt introductory manger flows into the Preparatory acidification pond that can get rid of the large grained  suspended substance, while adjust the volume& quality ,PH value, temperature of the dirty water, as well as to aeration previously which can transpire some poisonous substance by atmosphere transpiration , as to reduce volumetric organic loading rate.
2. The processed dung-dirt will enter into the Soft horizontal anaerobic reactor to anaerobic ferment. This project designed HRT namely that the time of the dung-dirt stay in the reactor is *0 days.
3. The Biogas dregs-liquid after anaerobic fermenting enter into the Biogas dregs-liquid pond, meanwhile fractional biogas liquid return to Preparatory acidification pond to periodic duty. The remnant biogas dregs-liquid processed by the biogas dregs-liquid pond’s aerobic action are used for farmland.
4. Biogas protector is used to relieve pressure of the biogas reactor bearing when the biogas production is more, as well as to prevent backfire.
5. The biogas will get rid of the in-water by the dehydration device, and then enter into the desulphurization device to wipe off the poisonous gas**-H2S in biogas. At last, it enters into the biogas storage; the biogas storage is mainly used for hold biogas to keep continuously and smoothly using.
6. The biogas voltage increased by the pump is used for various depletion systems such as: Biogas rice cooker Biogas cooker Biogas water heaterBiogas light etc.
