example 1

[0044] implement figure 1 An embodiment of the invention is shown to purify CO 2 polluted air. The reactor is a plate reactor with a single partition. The capacity of the reactor is 4L. The reactor works indoors. The initial concentration of Chlorella sp in the modified BBM was 1,200,000 microalgal cells / ml matrix. The temperature of the reactor tank was 30°C. The continuous light intensity of the LED device is 400μmol / m 2 the s -1 .The working cycle is two weeks. Inlet CO 2 The concentration is 490ppm, and the flow rate is 1000ml / min. After 24 hours, the CO at the outlet 2 The concentration was measured at 146ppm, consuming 70% of the CO 2 . The reactor can maintain more than 70% CO over a two-week duty cycle 2 consumption. Figure 4 The graph in shows the CO over a two-week working period 2 consumption performance.

example 2

[0046] implement figure 2 The embodiment of the invention shown to purify CO 2 polluted air. The reactor is a tubular reactor with a capacity of 1000ml. The ratio of diameter to height of the reactor is 1:10. The reactor works indoors. The initial concentration of Chlorella in the modified BBM was 1,200,000 microalgal cells / ml matrix. The temperature of the reaction tank was 30°C. The continuous light intensity of the LED device is 400μmol / m 2 the s -1 . CO at the inlet 2 The concentration is 450ppm, and the flow rate is 1000ml / min. After 24 hours, the gas outlet CO 2 Concentration measured at 90ppm, consumes more than 80% of CO 2 . The reactor can maintain more than 80% CO during 250 hours of operation 2 consumption. Figure 5 The curve in shows the CO over a two-week working period 2 consumption performance.

example 3

[0048] implement image 3 The embodiment of the invention shown to purify CO 2 polluted air. The reactor is a tubular reactor with a capacity of 100 L. The diameter and height ratio of the reactor is 1:5. Six reactors are placed in a row. The reactor was placed to work outdoors. The initial concentration of Chlorella in the modified BBM was 1,200,000 microalgal cells / ml matrix. Sunlight provides natural light to the medium. Inlet CO 2 The concentration is 400ppm, and the flow rate is 10L / min. After 72 hours, the CO at the outlet 2 Concentration measured at 45ppm, over 80% CO consumed 2 . The reactor can maintain more than 80% CO over an operating period of 18 days 2 Consumption, during a 30-day working period, can maintain 40% CO 2 consumption. Figure 6 The curve in shows the CO over a month of work 2 consumption performance.
