Sustainable circulating system for livestock farm

Abstract

The invention discloses a sustainable circulating system for a livestock farm. The sustainable circulating system comprises an ecological breeding unit for livestock stocking and a waste colleting unit arranged in the ecological breeding unit. The waste collecting unit is connected with a waste separating unit, the sewage collecting unit is connected with a marsh gas unit and a vermiculture unit,and the marsh gas unit is connected with a household energy consumption unit, a marsh gas power generation unit, an orchard planting unit, a fungus planting unit, a young loach breeding unit, an aquaculture unit and an organic vegetable unit. The aquaculture unit is connected with the fungus planting unit, the fungus planting unit is connected with the vermiculture unit, the vermiculture unit is connected with a poultry free-ranging unit, and the poultry free-ranging unit is connected with the orchard planting unit. According to the sustainable circulating system, local recyclable reutilization of livestock farm waste is achieved, the waste treatment cost of the livestock farm is reduced, pollution of the waste of the surroundings is reduced, and the new economic growth point of the livestock farm is achieved.

Description

technical field [0001] The invention belongs to the technical field of livestock breeding, and in particular relates to a sustainable circulation system of a farm. Background technique [0002] The aquaculture industry not only provides more industrial raw materials, but also provides rich food such as meat, milk, eggs, etc. for people's daily life, and will eventually provide draft animals and manure for agriculture; therefore, the aquaculture industry is an indispensable pillar industry of the country. Due to the gradual scarcity of land resources, captive breeding is widely used in breeding, and sewage discharge has gradually become a difficult problem in the breeding industry. Especially for large and medium-sized livestock breeding such as cattle and sheep, the cost of discharging waste liquid such as feces and urine accounts for a large part of the breeding cost. larger proportions. For the treatment of excrement, etc., most of them use the treatment method of ferment...

AI Technical Summary

Problems solved by technology

As for the treatment of excrement, etc., most of them use the treatment method of fermenting excrement and using it as farmyard manure. During the whole process, it needs to be transported to a designated place for fermentation treatment, and after fermentation, it is transported to a designated farmland for use as farmyard manure; including The transportation and fermentation cycle is longer, the cost is higher, and it occupies a larger land area; in addition, the excrement is directly transported to some places for random stacking, which will also increase the transportation cost and occupy an area, and will affect the surrounding environment. create pollution

Especially for waste liquids such as urine and flushing fluid, the discharge and transportation of feces and urine are extremely inconvenient. If they are discharged on site, they will cause a wide range of environmental pollution, and because of their evaporative properties, direct discharge is often used. , causing extremely bad impact on the surrounding environment, and the impact range is large
