Problems solved by technology

However, the current level of technology only stays at ventilation, fish farming, flowering, electrolyzed water, humidifiers, negative ion air purification technology, etc. These technologies can purify the air to a certain extent while adding new toxic substances. Emissions or energy loss, on the other hand, cannot effectively reduce the accumulation of indoor carbon dioxide, let alone directly reduce indoor carbon dioxide and replace it with fresh oxygen

Abstract

The invention provides an oxygen supply type dunaliella salina cultivating fluid and a preparation method and applications thereof. The cultivating fluid is green and troubled liquor containing dunaliella salina. On one hand, the culturing fluid can absorb carbon dioxide in air and release oxygen, and can realize the oxygen supply demand by lighting of a light source even under the dark closed space, and has controllability, thereby providing security guarantee for industries of petroleum drilling, coal mining and the like; and on the other hand, the culturing fluid can be used as daily seasoning for replacing salt, and can conduct easy health care in daily life without additional supplement of nutritional products as contained dunaliella salina is rich in abundant nutritional ingredients. The preparation method is simple, the oxygen supply type dunaliella salina cultivating fluid is produced by using a purely physical method, has no chemical pollutant, and production does not use fresh water, thereby saving the fresh water resource; and the thick brine having no use to other production can be recycled, thereby realizing reutilization of limited resources, and being suitable for demand of large-scale industrial production.

Description

technical field [0001] The invention relates to the field of air purification, in particular to an oxygen-supply type Dunaliella salina culture liquid and its preparation method and application. Background technique [0002] Air purification refers to the control of indoor air pollution, which can improve indoor air quality, improve living and office conditions, and improve physical and mental health. [0003] When people breathe, they need to inhale air, and the oxygen in the alveoli is taken in, and then the high concentration of carbon dioxide and other toxic and harmful gases are discharged. Studies have found that human lungs can discharge more than 20 kinds of toxic substances, of which more than 10 kinds contain volatile poisons. Therefore, people often feel dizzy and have difficulty breathing in crowded and poorly ventilated rooms. In severe cases, symptoms such as chest tightness, sweating, and nausea may occur. In addition, the sputum produced by coughing often c...
