PLANT FOR PURIFYING WASTE WATER FROM OIL PRODUCTS USING PRESSURE FLOTATION, SORBENT FILTER AND TWO-SECTION TANK Russian patent published in 2022 - IPC C02F1/40 C02F9/00 

FIELD: chemistry.

SUBSTANCE: invention relates to waste water treatment devices. Described is a waste water treatment plant from oil products using pressure flotation, a sorbent filter and a two-section tank, which includes a settling filter, reservoirs for collection of sewage, pure water and oil products, electric pump units, pipelines, gate valves, inspection device, heating element, wherein the settling filter is equipped with a heating element, a drain pipeline for oil products and a vibration level indicator, which is connected by a communication line to a relay connected to an electromagnetic valve and an audio signal, waste water collection tank is equipped with a collector, a drain pipeline for suspended substances and a vibration level indicator, which is connected by a communication line to a relay connected to an electric pump unit, an electromagnetic valve and an audio signal, tank for receiving oil products and suspended substances is made in two sections, wherein the first section is intended for receiving oil products with an upper layer of waste water, and the second section for receiving suspended substances with an upper layer of waste water, and wherein drain pipelines for oil products and suspended substances are installed below the level of vibration signalling devices at distances of 5–10 cm, oil products and suspended substances with an upper layer of waste water are drained into a tank for collecting oil products and suspended substances by gravity, without using electric pump units, and on the process pipeline connecting the settling filter with the waste water tank, an electric pump unit with an ejector, an electromagnetic valve and a thermometer are installed.

EFFECT: higher efficiency of waste water treatment.
