The exploration and application of a new dry fermentation biogas-pool.

A new dry fermentation biogas-pool(DFBP) was explored for family using in the countryside of Leting, Hebei province, China. The results showed that the biogas can be produced in a short time, and the methane percentage was over 40% on the second day by co-digestion of cornstalk and garden leaves. This kind of biogas was already suitable for the ignition. The daily biogas production was nearby 1 m3 with the methane percentage around 54% which can satisfy the needs of daily biogas using by family of three people. The biogas residue can be reused as fertilizer to return to field. The construction of DFBP can solve the problem of living garbage disposal and realize recycling utilization of the energy which is helpful to the environmental improvement in the countryside.
