摘要：
The present invention provides a joint method of cultivating microalgae combined with denitrating an industrial waste gas and a system useful for the same. The joint method comprises the steps of: (1) a step of cultivating microalgae; (2) a separation step of separating a microalgae suspension obtained from step (1) into a wet microalgae (microalgae biomass) and a residual cultivation solution; (3) a NOx absorbing/immobilizing step of denitrating an industrial waste gas with the residual cultivation solution obtained from step (2); wherein the nutrient stream absorbed with NOx obtained from step (3) is used to provide nitrogen source to the microalgae cultivation of step (1). During the microalgae cultivation, EM bacteria is added into the microalgae suspension. The microalgae is preferably Chlorella sp., Scenedesmus sp., Monoraphidium sp. or Spirulina sp.
