SYSTEM AND METHOD OF DRAINAGE AND TREATMENT OF STORM AND MELT WATER INTO THE GROUND Russian patent published in 2021 - IPC E03F1/00 

FIELD:

SUBSTANCE: invention relates to systems and methods for collecting, cleaning from suspensions, metal salts, residues of oil products and surfactants and drainage (infiltration) into the ground of storm and melt water in the absence of centralized storm sewers using drainage (infiltration) wells. The method of collecting, cleaning and discharging storm and melt water into the ground is that surface runoff enters the storm water inlet, after settling from heavy suspensions in the storm water inlet, they are directed through the pipeline to the inside of the filter element, through a drain pipe with holes in the wall, the water flow passes through the sorbent and already purified enters the space between the filtering element and the inner walls of the housing, after filling to a certain level, it enters the drainage wells through the pipeline for further drainage of the treated water flows into the ground. The system for drainage and treatment of storm water and melt water into the ground consists of a storm water inlet, a filter element and drainage wells, interconnected by a pipeline. The storm water inlet consists of a concrete base with a bottom, above which there is a concrete block without a bottom, on which a cast-iron block with slots-holes on the side is fixed for receiving drains, an inspection hatch is located on the cast-iron block. The filter element is made in the form of a cartridge as a single non-separable structure, with water-permeable upper and lower ends and a permeable side wall filled with zeolite and activated carbon, while the zeolite and activated carbon are located in the annular space along the entire length of the structure. Drainage wells are made of corrugated pipe and have perforations along the entire plane to drain surface wastewater, while stiffeners are mounted inside the well, which also have perforations.

EFFECT: provides a simplification of the design of local treatment facilities through the use of division of areas and their transfer directly to the places of formation of storm water, as well as an increase in the efficiency of cleaning storm and melt water.
