The invention particularly relates to a novel ultrasonic atomization microbubble generation and coagulation air floatation integrated sewage purification device. The device is characterized by consisting of a water inlet coagulation module, an ultrasonic microbubble generation module, an air floatation module and a control module, wherein the inlet water coagulation module is used for forming flocs through coagulation reaction of pretreated inlet water and a flocculating agent so as to meet the air floatation requirement; the ultrasonic micro-bubble generating module generates ultrasonic atomized micro-bubbles after pressure gas and water are introduced into the ultrasonic atomizing nozzle, the air floatation module enables micro-bubbles to be adhered to flocs to form dross to be removed,so that the water becomes clear, and the operation condition of the whole device is integrally controlled by the control module. Compared with a traditional test device, the ultrasonic atomizing nozzle technology is applied to the technical field of air floatation for the first time, uniform and sufficient microbubbles can be continuously provided under the condition of low energy consumption through the air pressure and water pressure adjusting device, and the device has the advantages of being high in microbubble generation efficiency, small in bubble, good in suspended matter removal effect, large in treatment capacity, convenient, safe, economical, efficient and the like.
Description
technical field [0001] The invention relates to a sewage treatment device, in particular to a novel ultrasonic atomization microbubble generation and coagulation air flotation integrated sewage purification device, which belongs to the technical field of sewage treatment air flotation. Background technique [0002] Air flotation is an efficient solid-liquid separation method. The principle is to generate a large number of microbubbles in the water, the bubbles are adsorbed on the suspended particles, and the solid particles are suspended to the water surface by buoyancy, thereby realizing solid-liquid separation. Air flotation can be used in sewage treatment, mineral separation and other fields. [0003] The size and density of microbubbles determine the efficiency of the air flotation method. Therefore, the generation of microbubbles is the core and key of the air flotation method. The generation methods of microbubbles required by air flotation generally include electrol...
