Embodiment Construction

[0029] In order to solve the technical problem in the prior art that when using Eupatoria adenophorum to ferment and produce biogas, it must first go through high cost, cumbersome process and complicated detoxification treatment. The invention provides a method with simple process, convenient operation and Inexpensive, suitable for widespread popularization, and suitable for producing biogas by fermenting Eupatorium adenophorum. The process method comprises the following steps,

[0030] a. Prepare fermented raw materials, harvest fresh Eupatorium adenophorum, remove leaves and roots, and make fermented raw materials;

[0031] B, stacking retting treatment, the fermented material prepared in step a is stacking retting under anaerobic environment for 2 to 4 days;

[0032] c. Fermentation treatment, extraction step b. Stack retting treatment qualified stacking retting raw materials are put into the raw liquid of the biogas digester at a material-liquid ratio of 320g / L-400g / L, an...

Abstract

The invention discloses a technological method for preparing methane by fermenting ageratina adenophora, belongs to the technical field of methane prepared from microorganisms, and provides the technological method for preparing methane by fermenting ageratina adenophora. The technological method, which is simple in process, convenient to operate, low in production cost, and suitable for wide application and popularization, comprises the following steps: a, preparing fermenting raw materials: harvesting fresh ageratina adenophora, and removing leaves and roots; b, performing stack retting treatment: performing the stack retting on the fermenting raw materials prepared from the step a in the anaerobic environment for 2-4 days; c, performing the fermenting treatment: extracting the qualified stack-retting raw materials from the fermenting raw materials subjected to stack retting in the step b, and feeding the qualified stack-retting raw materials in a stock solution in a methane tank according to the solid-liquid ratio of 320g / L-400 g / L, and fermenting at the temperature of 25-50 DEG C; d, collecting the gas yield, and leading out the methane generated through fermenting after the fermenting time is up to the set shortest time. Therefore, the technological processes of preparing the methane by fermenting ageratina adenophora not subjected to detoxification are finished.

Description

technical field [0001] The invention relates to a process method, in particular to a process method for producing biogas by fermenting Eupatorium adenophorum, and belongs to the technical field of biogas production by microorganisms. Background technique [0002] Eupatorium adenophorum belongs to dicotyledonous plant class, commonly known as aircraft grass, destruction grass and so on. It occurs widely in Sichuan, Yunnan, Guizhou, Tibet, and Taiwan. In 2010, the distribution area of ​​Eupatorium adenophorum in Liangshan Prefecture totaled 812,000 hm2. The windy, sunny and other natural climate factors in this area are suitable for its diffusion and reproduction, and it spreads eastward and northward with the southwest wind at a speed of about 60km per year. The State Environmental Protection Administration of my country listed the first batch of invasive alien species on the blacklist of 16 species. Eupatorium adenophorum has the characteristics of strong adaptability, inva...
