摘要

The obfuscating stripping module for on-site removing volatile solute substances from groundwater streams, comprises three vacuum-pressure-resistant obfuscation columns in water flow direction connected in series free from solid installations and packing body and with a column head (12) and a column bottom (13), where column water pumps are provided to the column bottom and a vacuum pump is parallely connected to a carrier gas flow through the obfuscation columns. A carrier gas obfuscating module (8) is provided with carrier gas column dosage units. The obfuscating stripping module for on-site removing volatile solute substances from groundwater streams, comprises three vacuum-pressure-resistant obfuscation columns in water flow direction connected in series free from solid installations and packing body and with a column head (12) and a column bottom (13), where column water pumps are provided to the column bottom and a vacuum pump is parallely connected to a carrier gas flow through the obfuscation columns. A carrier gas obfuscating module (8) is provided with carrier gas column dosage units assigned at the column head of the obfuscation columns in which the ground water is obscured with the carrier gas guided into a circulation. Multistage carrier gas purification modules (6) and a carrier gas quantitative restriction unit are provided into a carrier gas circulation. A water flow circulation control unit (5) is provided with three water flow control valves in the associated water pipes of the water pipeline system for the differential- or interval operation for distributing water flow between the water discharge pipe and a water circulation pipe. The carrier gas obfuscating module consists of a respective water jet pump, a diffuser-outflow pipe and an obfuscation nozzle downstream to the gas-water flow. A heat exchanger of the operating water circulation of the vacuum pump is contained in the water circulation line of the obfuscation columns. The water pipeline system is provided, and consists of water feed pipe, the water discharge pipe and water circulation line. A dosing device for reactive liquids is provided with static mixer module at a ground-water outlet for the effluent water flow. A closed vacuum carrier gas pipeline system is provided with a vacuum pump. A fresh carrier gas dosing device is provided with the static mixer module and gas supply unit and/or a carrier gas outlet below the gas purification system. An independent claim is included for a method for removing volatile solute substances from groundwater streams.
