Method for in-situ remediation of petroleum hydrocarbon polluted underground water by taking tourmaline as additive medium

The present invention relates to a method for in situ remediation tourmaline added as a petroleum hydrocarbon medium contaminated groundwater. First pretreatment peat, followed by expansion of functional bacteria culture, the culture will be expanded on the cured functional bacteria like wet peat, peat and then the load function bacteria, tourmaline, grit prepared according to the volume ratio of uniformly mixed 4:1:15 the reaction medium into the wall support, then charged the reaction medium permeable wall support wall reaction. PH can be adjusted tourmaline oil contaminated groundwater remediation process, increasing DO water, the reaction water 9h dissolved oxygen concentration increased from 5.60mg / L to 6.11mg / L; After addition of tourmaline dehydrogenase activity without tourmaline 2 times; cluster structure of water molecules is reduced, thereby enhancing the permeability of water molecules, and can improve the microbial degradation of petroleum dehydrogenase activity more conducive ground biodegradation of petroleum hydrocarbons. Tourmaline cluster structure of water molecules is reduced, clogging problems can largely alleviate PRB.
