Embodiment 1

[0043] The microalga cultivation system of closed track pool according to the present invention is the cultivation system of circular track pool (see Figure 8 ). The cultivation area 1, the carbon replenishment area 2 and the deoxygenation area 3 form a circular runway, and the length and width of the above components can be set according to the actual situation. The cultivation area 1 and the carbon replenishment area 3 are fully enclosed with a water sealing system and an anti-fog film, and the deoxygenation area 3 is enclosed separately. The circulating stirring device 7 is located at the connecting part of the carbon replenishing area and the cultivating area, and the gas in the upper part of the cultivating area 1 and the deoxygenating area 3 is connected to the external filtration and sterilization circulation ventilation system through pipelines. Set up a sampling channel in culture area 1 and carbon replenishment area 2, and install monitoring equipment such as onlin...

Embodiment 2

[0045] The microalga cultivation system of closed raceway pond of the present invention can be combined into more complicated cultivation system according to specific conditions (see Figure 9 ). The device can be composed of a plurality of cultivation areas 1, carbon replenishing areas 2 and deoxygenation areas 3, and the specific number can be set according to actual needs. The cultivation zone 1 and the carbon replenishment zone are sealed with a water seal system, and the deoxygenation zone 3 is sealed separately. Due to the lengthened runway, therefore, increased CO 2 The utilization efficiency, but at the same time need to increase the algae liquid circulation stirring device. Both the upper gas in the cultivation area and the deoxygenation area are connected to the external filtration and sterilization cycle ventilation system through pipelines, which ensures that the upper gas can be circulated and replaced at any time. Sampling channels are set up in culture area 1...

Abstract

The invention provides a closed raceway pond microalgae culture system, which consists of a carbon supply area, a culture area and an oxygen removal area and is closed by adopting an anti-fog film and a water seal mode. The bottom part of the culture area is provided with a heat exchange pipeline; the head space of the culture area is provided with a circulating ventilation system; and an online monitoring device for physiological, biochemical and nutrient elements is arranged in the culture area to realize the online monitoring and control for microalgae culture. The carbon supply area is provided with an enhanced carbon dioxide carbon supply device and an algae fluid circulating stirring device. The oxygen removal area has the functions of oxygen removal and a nutrient element charging pond, and the bottom of the oxygen removal area is provided with an air-blowing oxygen removal system. The carbon supply area and the culture area are communicated with each other; the oxygen removal area is closed singly; and culture fluid is communicated with the carbon supply area and the culture area through a downtank. The culture system has the advantages of less investment, easily amplifiedscale, good carbon supply effect, small biological pollution and the like, and can be used for sewage treatment, carbon dioxide gathering and residual heat utilization, thereby having remarkable economic benefit and excellent environmental benefit.

Description

technical field [0001] The invention relates to a microalgae cultivation system, in particular to a closed track pool microalgae cultivation system. Background technique [0002] Using biomass energy as energy is one of the main ways to alleviate the current energy crisis and environmental pollution. Microalgae can use solar energy and water to absorb carbon dioxide (CO 2 ), through photosynthesis, synthesize oil, starch, carbohydrates, cellulose and other biomass, and the growth cycle of microalgae is short, and the biomass accumulation is far greater than that of terrestrial plants. Therefore, research on microalgae has become a hotspot in current biomass research. However, how to cultivate microalgae and improve the biomass production capacity of microalgae has become a difficult point in the current research on the utilization of microalgae. [0003] The existing microalgae cultivation is mainly carried out in photobioreactors. So far, a wide variety of photobioreacto...
