COMPLEX FOR CLEANING GROUNDWATER CONTAMINATED WITH DISSOLVED PETROLEUM PRODUCTS AND A METHOD FOR CLEANING GROUNDWATER CONTAMINATED WITH DISSOLVED PETROLEUM PRODUCTS

摘要

FIELD: environment protection. ;SUBSTANCE: invention relates to environmental protection. The invention relates to a groundwater treatment complex contaminated with dissolved petroleum products, which includes the following blocks sequentially interconnected by cable or radio lines and pipeline systems, gas pipelines with shut-off valves: processing and monitoring unit 1, containing the front of cased scavenger wells 7-16, before and after which observation wells 27-29 are located, result processing and sensor control unit 2, suspension depth control unit of metering devices 3, aeration station 4, laboratory complex 5 and a container for introducing bacterial culture biomass of native oil-oxidizing microorganisms and mineral components 6, while the output of the processing and monitoring unit 1 is connected by a cable line to the input of the result processing and sensor control unit 2, the output of which is connected by a cable line to the input of the suspension depth control unit of metering devices 3, the output of the suspension depth control unit of metering devices is connected to the 1st input of the processing and monitoring unit 1, the second input of which is connected by pipelines to the input of the aeration station unit 4, and the 3rd entrance is connected via pipelines to a container block for introducing biomass of bacterial culture of native oil-oxidizing microorganisms and mineral components 6, and the tank entrance is connected by pipelines to the output of the laboratory complex 5. The invention also concerns a method for cleaning groundwater contaminated with dissolved petroleum products used in the complex. ;EFFECT: reducing the harmful impact on the environment by decreasing the exposure time and improving the quality of groundwater purification from dissolved oil pollution. ;10 cl, 3 dwg, 1 tbl
