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 a nutritional-type dunaliella salina culture fluid, as well as a preparation method and an application thereof. The culture fluid is red turbid liquid algae-laden water of which the quantity of dunaliella salina is 300000-400000 / ml and the content of carotenoid is 10g / m<3>. On the one hand, the culture fluid can absorb carbon dioxide in air and release oxygen at the same time, has controllability, and provides safety guarantee for industries such as petroleum drilling, and coal mining, and on the other hand, the culture liquid can be used as a daily condiment instead of salt. The contained dunaliella salina contains abundant nutritional ingredients, so that health protection can be easily achieved in daily life; nourishement does not need to be supplied in addition; the nutritional-type dunaliella salina culture fluid is simple in preparation method, is produced by a purely physical method, does not contain chemical pollutants, and is produced without fresh water. Therefore, the fresh water resources are saved. Meanwhile, concentrated brine which has no use in other production is recycled, thus, recycling of limited resources is achieved, and the preparation method is suitable for the requirement of large-scale industrial production.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a nutrient-type Dunaliella salina culture solution 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 conta...
