Description

The invention relates to water supply, in particular, to systems for artificially replenishing the groundwater reserves of exploited aquifers.

The purpose of the invention is to increase the average per pool filter productivity.

FIG. 1 shows an infiltration basin when filled with water, a cross-section; in fig. 2 - the same, longitudinal section (arrows show the direction of water movement).

The infiltration basin includes pontoon devices 1, removable flexible shells 2, which are fastened to the bottom of the pool with cables 3 and anchors 4, and a water supply device 5 that fills the pool to the working

with ein reduces its performance to an acceptable value. Thereafter, the water supply to the pool is stopped and its emptying is performed. The Ilis-Tbiji sediment from the accumulation zones 9 is flushed into the catchment tray 12 and discharged into the sewage system or is discharged through the drainage system outside the basin. Removable flexible shells 2 and pontoon devices-1 are removed from the filtering surface and the filtering load 11 is regenerated, for example, using a scraper, a layer of silt is removed and a sloped load layer 11 is removed and replaced with clean ground. Then again at the bottom. pontoon devices 1 are installed on the basin and flexible shells 2 are placed on them, and after filling 6 waters, corridors 7 separated 20 by a pool of water to the working level from the upper tusk 8 of the pool where the pool 6 resumes operation.

an area of accumulation of silt sediment is located, the front part 10 of corridor 7 is open, allowing water to pass to the filtering load 11, and the catchment tray 12 ..

The pool works as follows.

At the bottom of the infiltration basin, pontoon devices 1, made, for example, of polyethylene film in the form of inflatable containers, are installed, removable flexible shells 2 are laid on them, with inlet, made of dense fabric or polyethylene film, which along the contour is attached to the bottom of the pool with the help of cables 3 and aiker 4. Through

devices 5 for water supply pool 40 construction of buildings

it is filled with water up to the working level 6. Due to the pushing force, the pontoon devices 1 float out of the flexible shells 2, forming corridors 7. The water in the upper floor of the bas 45 seina 8 is freed from the main amount of suspension falling onto the surface of the flexible shells 2, The resulting muddy sediment slides over their surface and accumulates in the sediment accumulation zone 9. The clarified water through the open end portion 10 of the corridors 7 enters them and is filtered through the filter charge 1 1 into the soil. As the filter charge clogs up and a baso sludge film forms on its surface

The Ilis-Tbiji sediment from the accumulation zones 9 is flushed into the catchment tray 12 and discharged into the sewage system or is discharged through the drainage system outside the basin.

The use of infiltration basins of the proposed design for the artificial replenishment of groundwater is especially effective in areas with difficult climatic conditions. For example, in areas with a prolonged freezing period, by increasing the duration of the filter cycle, it is close to the maximum pool capacity. With frequent rain floods, characterized by a sharp increase in water turbidity in

The filtration pools provide for preliminary purification of water and there is no need to switch off the pools for the period of floods or the unprepared preparation of water, which is used in the practice of water supply.

Formula Invention

An infiltration basin, including a rectangular trench with f | 4-loading load of sandy material and a device for water supply,

ZO is different because, in order to maintain the pool performance, average for the filter cycle, it is equipped with flexible removable shells with pontoon devices, which are located at the bottom of the pool, longitudinal corridors with an end part open on one side.
