Embodiment Construction

[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0040] Such as Figures 1 to 3 As shown, a paddy field mixed fermentation biogas production system includes a paddy field fermentation area 1, and straw and farmyard manure are laid on the paddy field fermentation area 1. It is connected with the gas collection bin 4 through the connecting pipe 3 . In this example, the weight ratio of straw to farmyard manure is 1:1, and the types of farmyard manure can be adjusted according to local conditions. The preferred order is pig manure, biogas slurry, cow manure, and sheep manure.

[0041] Preferably, an annular ditch 5 is opened around the paddy field fermentation area 1 , and the bottom of the side wall of the fermentation bin 2 is set in the annular ditch 5 .

[0042] Preferably, the fermentation chamber 2 is a hollow cuboid structure with open top and bottom, the top of the fermentatio...

Abstract

The invention discloses a methane production system with mixed fermentation for a paddy field and a method thereof. The system part comprises a paddy field fermentation area, wherein straws and farmyard manure are spread on the paddy field fermentation area; the upper side of the paddy field fermentation area is covered through a fermentation bin; and an air outlet of the fermentation bin is connected with a gas collection bin through a connecting pipeline. Furthermore, the invention further discloses a corresponding method. According to the method, straws and farmyard manure are mixed and fermented with sludge in the paddy field to form a whole set of paddy field methane production and collection system. The paddy field methane is resourced, the problem of disposing agricultural waste canbe solved to facilitate carbon emission on the one hand, and on the other hand, rural energy supply can be increased.

Description

technical field [0001] The invention relates to the technical field of biogas production, in particular to a paddy field mixed fermentation biogas production system and a method thereof. Background technique [0002] The gas and particulate matter produced by rice straw burning are extremely harmful to the atmosphere, and are also one of the important sources of carbon emissions. They have not only become the bottleneck of rural environmental protection, but even become the chief culprit of the urban environment. From a domestic point of view, direct return of straw to the field affects crop growth, incineration pollutes the atmospheric environment, and comprehensive development and utilization face the dilemma of immature technology, relatively large investment, and relatively poor results. The rational use of straw has always been a hot topic in agricultural production and environmental protection. With the development of agriculture and animal husbandry in recent years, ...
