PL441679A1 - System for photocatalytic degradation and removal of antibiotics from wastewater - Google Patents

Abstract

The subject of the application is a system for photocatalytic degradation and removal of antibiotics from wastewater, including a dispenser (1) for reagents (a, b), a reaction chamber (2), UV-C lamps (3), a wastewater pump (4), a tank (5) for reagents (a , b) and a gas dispersant (6). It is characterized by the fact that the feeder (1) of reagents (a, b) is an injector feeder and its inlet is connected to the sewage system cleared of suspended solids through the sewage pump (4), and the supply of the feeder (1) of reagents (a, b) ) is connected to the tank (5) of reagents (a, b), which are an aqueous suspension of the photocatalytic substance and an aqueous solution of the oxidant. The outlet of the dispenser (1) of reagents (a, b) is connected to the reaction chamber (2) divided by the first overflow partition (2.1) into two parts. The walls of the reaction chamber (2) are made of a material that transmits UV-C radiation. UV-C radiators (3) are installed on the outer side of the walls of the reaction chamber (2). At the bottom of the first part of the reaction chamber (2) there is a gas dispersant (6), and inside the second part of the reaction chamber (2) there is an ultrasound generator (7). At the end of the second part of the reaction chamber (2) a second overflow baffle (2.2) is mounted. At the top of the reaction chamber (2) a gas extractor (8) is installed, which is connected to the gas disperser (6) through a gas pump (9). Behind the second overflow partition (2.2) of the reaction chamber (2), in the sewage flow path, there are successively the liquid pump (10) and the hydrocyclone (11), whose outlet is connected through the manifold (12) with the tank of the photocatalytic substance (13) and with tank (5) of reagents (a, b). The hydrocyclone overflow (11) is connected to the liquid filter (14).
