FIELD: ecology.
SUBSTANCE: claimed group of inventions refers to the field of cleaning industrial and domestic contaminated water and is designed to prevent the formation of smells of foul smelling substances (WPV) in the transportation and treatment of wastewater, including to treatment facilities. This method of preventing the formation of smells of foul-smelling substances (WPV) in wastewater transportation and treatment systems includes the collection of effluents consisting of a liquid and a gas-air phase, and their feeding through the pressure pipeline to the physical and chemical treatment facilities. Before the discharge of effluents through the pressure pipeline, the liquid and gas-air phases of the effluents are co-processed in a device installed at a sewage pumping station, where before the liquid phase of the effluents is mixed with the gas-air phase, the liquid phase of the effluent is accelerated, giving it a helical movement, processing it with low-intensity cavitation and mixing with atmospheric air. In the process of mixing the aerated liquid phase of the effluent with the gas-air phase of the effluent due to further acceleration and turbulization of the formed stream, containing organic substances that cause odor of WPV, produce their oxidation and electrocoagulation. Preventing odor generation of the WPV apparatus comprises receiving tank 1, receiving chamber 2 of a sewage pumping station 3, gravity conduit 5, device 6 for intensifying the oxidizing ability of a low intensity cavitation, air supply device 7, intake 8, pump 10, device for activating the process 11, including an acceleration and formation chamber for the helical flow and an electrocoagulation chamber at its outlet.
EFFECT: invention prevents the appearance of odors of WPV in the system of transportation and treatment of wastewater to treatment facilities.
