Abstract

The invention relates to a method for generating biogas through anaerobic fermentation by taking traditional Chinese medicine dregs as raw materials. Medicine dregs produced in a pharmaceutical factory of traditional Chinese medicine are used as fermentation raw materials, are united with waste water of the pharmaceutical factory for anaerobic fermentation, and are properly proportioned with biogas slurry and water for composting pretreatment, a proper amount of NaOH is added after the mixture enters a pool, the TS (total solid) concentration of the fermentation raw materials is 7-9%, 10-15% of biogas slurry is added as an inoculum so as to realize quick start, and the biogas production efficiency is high. Partial biogas slurry flows back after normal operation so as to ensure the concentration of microorganisms in an anaerobic tank. The traditional Chinese medicine dregs are taken as main raw materials for fermentation to produce the biogas, cow dung and other fermentation raw materials do not need to be added, the operation is simple, the gas production effect is good, the utilization ratio of the raw materials is high, the problem of environment pollution caused by the medicinedregs and the waste water can be solved, and simultaneously biogas energy sources can be recycled.

Description

technical field [0001] The invention relates to a method for producing biogas by anaerobic fermentation using traditional Chinese medicine dregs as raw materials, and belongs to the technical field of comprehensive utilization of organic waste. Background technique [0002] China is a major producer of traditional Chinese medicines. According to incomplete statistics, Chinese medicine companies in my country currently consume about 700,000 tons of herbal medicinal materials each year, and produce millions of tons of medicinal residues (including moisture). Because of the pollution to the environment in different degrees, it has been treated by landfill, which not only takes up a lot of land resources, pollutes the land and groundwater, but also causes a waste of resources. Therefore how to effectively process and utilize the dregs of traditional Chinese medicine has become an urgent problem for Chinese medicine manufacturers. Because the dregs of traditional Chinese medicin...
