The system is mainly composed of odor collection and transportation system, microalgae absorption and utilization system, light auxiliary system, algal cell collection system, rainwater collection and transportation system, pig house washing wastewater collection and transportation system and oxygen transportation system. The odor generated in the pig house is collected by the odor collection and delivery system and transported to the microalgae absorption and utilization system, so as to be absorbed and utilized by the microalgae. Microalgae use a mixture of pig house washing wastewater and rainwater as a culture medium, rely on sunlight as a light source, and absorb odor and carbon dioxide in the air for self-proliferation and collection through an algal cell collection system. The collected algal cells can be used as pig feed. The oxygen released by the photosynthesis of microalgae can be transported to the pig house to further improve the air quality of the pig house. The invention has a simple structure and can effectively convert the odor of pig farms into microalgae biomass and oxygen, thereby realizing its recycling.

本发明通过臭气收集与输送系统将猪舍中产生的氨气和硫化氢等臭气收集并输送至微藻吸收利用系统，微藻吸收利用系统中的微藻利用猪舍冲洗废水和雨水混合物作为培养基，依靠太阳光作为光源（光照不足时可由光照辅助系统补光），同时吸收臭气和空气中二氧化碳进行自身增殖并通过藻细胞收集系统进行收集，收集后的藻细胞可作为猪饲料。微藻光合作用释放出的氧气通过氧气氧气输送管道可输送至猪舍进一步提高猪舍空气质量。本发明结构简单，能有效将猪场臭气转化成微藻生物质和氧气，从而实现其循环利用。The invention collects and transports odors such as ammonia and hydrogen sulfide generated in the pig house to the microalgae absorption and utilization system through the odor collection and transportation system, and the microalgae in the microalgae absorption and utilization system uses the pig house to wash the waste water and rainwater mixture As a culture medium, relying on sunlight as a light source (the light can be supplemented by a light auxiliary system when the light is insufficient), and at the same time absorbs odor and carbon dioxide in the air for self-proliferation and is collected by an algal cell collection system, and the collected algal cells can be used as pig feed . The oxygen released by the photosynthesis of microalgae can be transported to the pig house through the oxygen oxygen transmission pipeline to further improve the air quality of the pig house. The invention has a simple structure and can effectively convert the odor of pig farms into microalgae biomass and oxygen, thereby realizing its recycling.
上述实施例和图式并非限定本发明的产品形态和式样，任何所属技术领域的普通技术人员对其所做的适当变化或修饰，皆应视为不脱离本发明的专利范畴。The above-mentioned embodiments and drawings do not limit the product form and style of the present invention, and any appropriate changes or modifications made by those of ordinary skill in the art should be regarded as not departing from the scope of the present invention.
