AUTOMATED SYSTEM FOR CLEANING MULTICOMPONENT INDUSTRIAL EFFLUENT Russian patent published in 2020 - IPC C02F1/463 

FIELD: chemistry.

SUBSTANCE: invention relates to industrial wastewater treatment systems by electrochemical treatment of water and can be used in enterprises of electronic, instrument-making industry, as well as in industries with galvanic shops and sections. Cleaning system comprises in-series connected receiving chamber with reagent dosing unit installed above it, static mixer, electric coagulator with electrodes and blade mixer, pH meter sensors, chamber with high-pressure pump, pressure sorption filter, receiving tank for wet residue, press filter, concentration meters of heavy metal impurities, pump for transfer of under-treated water, storage tank, pump for water supply for repeated cleaning cycle, control valves, microprocessor controllers, pump for transfer of under-purified water, accumulating tank, ultrasonic flow meter on inlet pipeline, corrector of reagent supply, adder, scaling and correcting amplifiers, setter of input flow, unit for comparing flows, frequency regulators and mixer agitation speed adjuster by blade mixer, purified water pressure sensor, washing water pressure sensor, scaling amplifier, pump drive starter for water supply to flushing, high-pressure pump drive starter, valves on water supply pipeline before and after flushing of pressure sorption filter, upper and lower pickups of sediment level in electric coagulator, sluice pump actuator.

EFFECT: technical result of the invention is improved quality of water treatment and efficiency of operation by means of introduction of sorption post-treatment, removal of galvanic sludge at the stage of its formation and control of parameters of plant operation depending on volume and chemical composition of effluents supplied for purification.
