Farm stench treatment method and system

Abstract

The invention discloses a farm stench treatment system and method. The method comprises the following steps that a plurality of draught fans are installed on a wall body of a breeding house, the draught fans respectively convey stench into a reaction tank through a pipeline, a drought fan and a water pump are further arranged on the reaction tank, and carbon dioxide gases generated by the reactiontank are conveyed to a plant cultivation factory to serve as a gaseous fertilizer through a conveyance pipeline by the drought fan; the water pump is connected to a liquid storage tank through the pipeline, and the liquid storage tank is connected with a mixing tank through the water pump; a nutritional ingredient addition opening is formed in the mixing tank in which a nutrient solution is formed, and the nutrient solution is pumped to a nutrient solution conveyance pipeline by the water pump; the end of the nutrient solution conveyance pipeline is provided with an atomization head, and theabove nutrient solution is spayed by the nutrient solution conveyance pipeline to plant roots in the plant cultivation factory through the atomization head.

Description

technical field [0001] The invention belongs to a method and a system for treating odor of a farm. Background technique [0002] In modern intensive breeding, most of the livestock and poultry are in a relatively closed environment, the breeding density is high, and the air in the house is very pungent, which can easily cause panting disease and bronchial inflammation of livestock and poultry, which greatly affects the health and growth rate of livestock and poultry. cause serious economic losses. In addition, the odor of the farm is discharged into the air and affects the lives of residents. It is one of the sources of air pollution. At present, there is no economical and applicable method for the treatment of the odor of the farm. [0003] The odor components of farms are complex, mainly NH 3 ;CO 2 Although there is no odor, the high concentration of CO 2 Seriously affect the health of livestock and poultry, it is produced by the breathing of livestock and poultry an...

Problems solved by technology

Studies have shown that if the CO 2 When the concentration is increased from the atmospheric concentration (about 300PPM) to 1000PPM, the photosynthetic efficiency of plants can be more than doubled, and it can be used as a gas fertilizer in plant cultivation, while NH 3 Convert to NH 4 + After that, it can be used by plants as nitrogen fertilizer. It can be seen that the harmful substances used as farms are indeed the nutrients needed by plants, and the O released by plants 2 It is also lacking in livestock and poultry houses, but plants in traditional planting methods cannot directly use NH 3 and CO 2 The utilization rate is extremely low, and the purpose of improving the livestock and poultry houses and the atmospheric environment cannot be achieved. At the same time, a large area of ​​land is required, and it is difficult to implement in actual production.
