The invention discloses a process and a system for preparing spirulina culture solution from low-concentration alkaline lake brine. The system comprises a waste saline-alkaline lake, a water pump, a carbonization tower, a gas compressor and a spirulina culture pond. The process comprises the following steps: (1) detecting the total alkaline concentration of the low-concentration alkaline lake brine; (2) pumping the alkaline lake brine into the carbonization tower and carbonizing; (3) detecting the carbonized alkaline lake brine; and (4) preparing the spirulina culture solution. The process and the system have the advantages that: culture cost of the spirulina is greatly reduced; market competitive capacity is enhanced; and waste gas containing carbon dioxide is used for carbonizing the brine, so the carbon dioxide concentration of the waste gas is reduced, the discharge amount of the carbon dioxide is reduced and environmental friendliness is facilitated. The process is advanced in technology, controllable in
