CONTROL METHOD AND DEVICE FOR LOCAL TREATMENT OF DRAINAGE WATER Russian patent published in 2024 - IPC C02F1/28 E02B11/00 B01D25/02 

FIELD: water treatment.

SUBSTANCE: invention relates to techniques for controlling purification of drainage runoff and can be used in land reclamation in irrigation systems and in water protection measures. The method includes dividing the collector drainage network of the irrigation system into areas, drainage from which enters the corresponding drainage wells built on the route of closed collectors, and then is discharged into the main collector canal. Organize periodic sampling of drainage runoff for chemical analysis from drainage wells. Based on the results of the analysis and data on metering waste flow, combinations and sets of removable cartridges with a sorbent made of ion exchange resins, anti-filtration material or without filler are selected. Devices for cleaning drainage are installed on the outlet connecting pipes of drainage wells. At the mouths of the closed collectors, drainage flow metering units are installed. The cleaning device contains an outlet pipe, two cylinders arranged in series, longitudinally divided into eight cells by common waterproof walls. On the side walls of the cylinders, there are inlet openings for removable cartridges filled with sorbent made of ion exchange resins, anti-filtration material, or without filler. The cartridges consist of flexible locking joints that are inserted into the grooves of the cylinders, a frame with a mesh stretched over it with holes of 0.1 mm in size, fixed by means of clamping strips, fastening rods and teeth.

EFFECT: simplifying the design of the treatment device and increasing the speed of treatment control by selecting a combination and sets of removable cartridges based on the results of sampling and drainage flow metering data.
