Providing a gas-liquid supply apparatus may be made without requiring additional equipment, and to improve the stirring efficiency, to reduce the micro-bubbling and homogenization of the gas-liquid mixed fluid. An orifice 3A of the semi-circular shape of the nozzle to the suction end of the positive-displacement pump 7 of electromagnetic pump or the like, to liquid flow management in any proportion, of a removable ≧ 4 (mm) thickness, the pump inlet portion of the downstream is provided with a gas suction communication passage 200, the pump outlet, is provided to the mixer 8 for the gas-liquid mixed. [Selection] Figure Figure 1追加設備を必要とすることなく、攪拌効率を向上して、気液混合流体の均質化やマイクロバブル化を図ることができる気液供給装置を提供する。電磁ポンプ等の容積型ポンプ7の吸入部に、任意の割合で液体流量管理する、着脱可能な厚さ≧4(mm)の半円ノズル形状のオリフィス3Aを設け、その下流のポンプ入口部に、気体吸入連通路200を設け、ポンプ出口部には、気液混在のためのミキサー8を設けた。【選択図】図1
