MODULAR SYSTEM FOR RECULTIVATION PROCESSING OF CONTAMINATED UNDERGROUND LAYER AND CORRESPONDING METHOD Russian patent published in 2021 - IPC B09C1/00 

FIELD: recultivation.

SUBSTANCE: present invention relates to system (10) for recultivation processing in-situ of a contaminated underground layer within a given space-limited section and to a corresponding method. System (10) contains a certain number of modular units (11a, 11b, 11c, 11d, 11e, 11f, 11g, 11h, 11i) connected to each other, wherein each of the specified modular units is a separate independent device made with the possibility of implementation of a characteristic given function related to recultivation processing of the contaminated underground layer. A possibility is provided of regulating a number and an order of arrangement of the specified modular units in system (10). The method for recultivation processing of the contaminated underground layer within recultivation section (41) consists in that system (10) is connected to a certain number of wells (22, 22a) located within recultivation section (41) by means of pipeline network (21, 21a); nutrients, reducing agents and washing liquids (23a) are supplied from system (10) to the underground layer through a certain number of injection wells (22a); fluid medium (42) containing contaminants is received from the underground layer to system (10) through a certain number of pumping wells (22); contaminants present in fluid medium (42) are removed due to passing specified fluid medium (42) through a certain number of above-mentioned modular units (11a, 11b, 11c, 11d, 11e, 11f, 11g, 11h, 11i) connected to each other in system (10) to obtain fluid medium (23) that essentially does not contain contaminants. The use of system (10) is carried out within recultivation section (41), wherein the underground layer is any of the following: soil, subsoil water and underground accumulations of gas medium.

EFFECT: exceptional flexibility is provided in terms of implementation of various existent recultivation technologies, in particular in-situ recultivation technologies, directly at the place of works and by means of a single device/system; besides, the invention allows implementation of specialized recultivation strategies in a reliable and cost-effective method with minimum time spent.
