In-situ bioremediation method for combined treatment of aeration zone and saturated zone

The embodiment of the invention provides an in-situ bioremediation method for combined treatment of an aeration zone and a saturated zone, which comprises the following steps of: after simultaneously injecting an aerobic biological agent and a nutritional additive into remediation wells of the aeration zone and the saturated zone, injecting mixed gas of aerobic gas and matrix gas required by microorganisms into the remediation wells of the saturated zone; and part of the injected mixed gas enters the aeration zone from the saturated zone, so that the mixed gas is utilized by the aerobic biological bacteria injected into the aeration zone. The injected aerobic biological agent can breed and grow by using matrix gas, has a good co-metabolism degradation effect on chlorohydrocarbon or benzene series and the like under an aerobic condition, and finally achieves the purpose of combined treatment and restoration of an aeration zone and a saturated zone. 本发明实施例提供了一种包气带和饱和带联合治理的原位生物修复方法，在包气带和饱和带的修复井中同时注入好氧生物菌剂和营养助剂后，
