WASTE WATER COLLECTION, TREATMENT AND TRANSPORTATION SYSTEM Russian patent published in 2021 - IPC E03F3/00 C02F1/50 

FIELD: water treatment.

SUBSTANCE: invention relates to the field of water treatment, namely to sewer pipeline hydraulic systems for collecting, cleaning and transporting industrial rainwater and household wastewater. The system contains a gas separation housing, a triethylene glycol regeneration housing, a water treatment complex and a domestic wastewater treatment plant connected to each other by means of pipelines for transporting wastewater. In the mentioned premises, four chemical reagent dosing units are installed, consisting of flow tanks (5) equipped with corrosion inhibitor input nodes (6) into protected pipelines for the transportation of household wastewater. Each of the input nodes (6) includes a manual control valve (7), a drain valve (8) connected by a chemical reagent input pipeline (9), and a detachable flange (10) with a supply tube (11) equipped with a spray nozzle (12). The first dosing unit is installed in the gas separation housing. The second dosing unit is installed in the triethylene glycol regeneration housing. The third dosing unit is installed in the water treatment complex. The fourth dosing unit is installed on the territory of the domestic wastewater treatment plant.

EFFECT: invention makes it possible to reduce the rate of corrosion processes occurring in the equipment of the wastewater collection, treatment and injection system into the absorbing reservoir.
