(1) The technical field to which the design belongs;This paper is a device that purifies leather wastewater and high concentration organic wastewater by combining ultrasonic wave, ozone and ultraviolet ray in wastewater.;(2) Purpose of devising;Ultrasonic wave for the purification of high concentration hardly decomposed organic wastewater or leather wastewater. ozone. In order to improve the efficacy of the reaction, that is, decomposition oxidative power, a multi-stage cascade reactor is connected to the waste water so that the waste water is upstream, and the waste water is stirred at a high speed with a reflector of ultrasonic waves in order to avoid blind spots. In addition to improving the ozone effect, the ultraviolet light is refracted to cause light gathering to improve the efficacy.;(3) constitution;When the wastewater flows in, the lowest reaction tank causes the combined reaction by the irradiation of ozone and ultrasonic waves, and the continuous reaction occurs upstream to the reactor connected up one level continuously. At this time, an ultrasonic reflector is placed to remove the blind spot of the reaction. A lamp and agitator are installed to help the ozone bubbles to react smoothly. Also, the ultraviolet light is refracted to collect the light, and a filter tank is installed to completely remove the residual sludge.;(4) effect of design;Nitrogen in refractory organic wastewater or leather wastewater. sign. Heavy metals such as chromium are contained, so when it enters rivers or the sea, eutrophication occurs and green algae or red tide occur, causing fish to be killed.
