摘要
In this paper,the removal of trace carbon dioxide from closed spaces through membrane process and biotrans-formation are introduced in detail.These methods include the microalgae photobioreactor,membrane microalgae photobio-reactor,supported liquid membrane,membrane gas-liquid contactor,hydrogel membrane,and enzyme membrane biore-actor.The advantages and disadvantages of these methods are compared.It is found that higher CO_(2) removal efficiency can be obtained in biotransformation and membrane process.However,a large volume and high energy consumption are needed in biotransformation,while the low permeability and stability must be solved in the membrane process.
