An experimental study of rice straw biological pretreatment to produce biogas

摘要

Straw is the main source of biomass energy. And Straw resources are very rich in our country. In order to achieve the energy efficiency of straw and promote the technology of using rice straw to produce biogas over large areas, a method of using biological pretreatment on anaerobic digestion to produce biogas is put forward. A set of experimental device is designed to study the technology of making biogas by anaerobic digestion on the base of biological pretreatment. Study the impact of rice straw length, biological pretreatment time and anaerobic digestion temperature on gas production when rice straw is biological pretreated. And then determine the optimal anaerobic digestion conditions to improve the biogas production.
