WO1998002600A1 - Method for cleaning capillary and porous media - Google Patents

Abstract

The present invention pertains to the field of electro-osmotic technology and may be used for cleaning objects in the environment which have a capillary and porous structure (i.e., soil, rocks, etc.) and have been contaminated by crude oil or petroleum products. This device includes electrodes and more precisely an anode and a cathode connected to a direct current power supply. The device also comprises a vessel for the cleaning liquid, said vessel having a distribution system penetrating into the zone of the capillary and porous medium to be cleaned. The device eventually comprises a manifold for collecting the liquid separated at the cathode, said manifold being connected by a duct to the distribution system. The vessel for the cleaning fluid contains a solution of micro-organisms capable of oxidising the crude oil. This device may be used for the effective cleaning of capillary and porous media which have been contaminated by heavy metals as well as by intermediate and light crude oil fractions.

PRESENT LEVEL OF TECHNOLOGY

It is known that, for the sake of purely good faith, which is included in the ground and is justified, there is only one excluded (170)

The device is equipped with a wash basin, made in the form of a pool, limited by earthen rollers in the area of a cleaned area.

It is easy to ensure that there is a connected part of the contaminants (heavy metals, a loss of income) in clay, and anion is associated with exchange of potassium and gives rise to

It only saves them from migration and reduces the concentration of heavy metals and radionuclides in the zone of non-occupancy. Есο eat. contaminations are not removed at all. and is disbursed in a related form from soil to 2 subordinate layer.

It is known for the calculation of a capillary-pure medium, including those included in the cleaned medium - anodes and cathodes, which are excluded; the device is clean for the cleaning liquid with a distributive system in the form of a pipe, which are immediately withdrawn to the account of the payment of an empty medium; the anodes are made in the form of a transformed; there is a collector for the discharge of liquid emitted from the process fluid, made in the form of a container that is connected with the use of the finished product, which is supplied by the consumer

With the help of the devices, they can be removed to one degree or another to the extent that the free-lying ones that are not part of the structure of the group are heavy. Contaminants are collected in the collector and then removed together with the processed fluid.

However, this device does not allow the removal of light, medium and heavy oil fractions from the cleaned medium. included in the group. With this, the cleaning fluid after it is collected in the collector is mixed with contaminants. The direct use of it by the use of this device is not suitable. If, as a cleaning liquid, the reagent is used, it affects the reagents. 3 soil contaminants in the process of calculating it, this means that the process is ineffective for these reagents.

BEST MODE FOR CARRYING OUT THE INVENTION

The device in a commercial embodiment includes anode 1, made in the form of a pipe with an internal diameter of 50 mm, introduced into the cleaned medium, in particular. to the ground to a depth of 1 m. Part of the soil above part of the soil part of the anode 1 was performed 6 good, shipped to the ground - equipped with refrigeration. Step 2 is also made in the form of a pipe, loaded into the ground to a depth of 1 m and equipped with a deepening in the buried part. Internal diameter of cathode 2 - 80 mm.

Station 7 is connected to main 8, and includes a central pump 9 and center 10, which is connected to the distribution system 6.

A capacity of 5 contains a solution of 1 1 non-oxidizing microorganisms.

Β Variants of the device for fig. 2 anode 1 and stage 2 are performed 7 in the form of hi-tech distributed plates mixed in a well-functioning overclocking box 12. Unit 1 is overloaded from below. The distance between the housing 2 and the bottom of the housing 12 is 150 mm. Part 7 in this case is located between step 2 and the bottom of building 12. This option of the device is intended for the calculation of loads with an external structure. The cleaned group is located between the anode 1 and the cathode 2, and above the anode 1. The distance between the anode and the cassette is 1, 2 m. It is necessary to do so. From a capacity of 5, a discontinuity of 1 1 with non-depleting microorganisms arises through a distributive system of 6, which, in part, is partially irrelevant. Κ anode 1 and step 2 turn on the source 3 of the constant electric current. An electric field is created with a weight of 200 Β / m.

For soil contaminated with oil, there are immiscible liquids - water and oil. On the border of the section “particles of the group - water”, “water - oil”, double electric layers are formed. The movement of ions of double electric layers is subject to the movement of the territory of the division of two liquids. Ions moving in water cause the movement of fresh moisture in soil, a waste of 1 1 with non-oxidizing microorganisms, and also often partial. In this way, a well-organized electrical movement of the device 1 1 with microorganisms and without anode is generated. First, in unit 2, moisture is accumulated. Then

8 There is a separation of the whole amount of cleanup 11 with non-oxidizing microorganisms. Hygiene companies dispose of carbohydrates in carbon dioxide and water. snοva ποdayuτsya in ρasπρedeliτelnuyu sisτemu 6.
