Electrolytic flotation device for wastewater treatment

Abstract

The invention relates to an electrolysis flotation device for wastewater treatment. The device comprises a pool, a first motor, a disc, a cathode, an anode, a moving mechanism and a cleaning mechanism, wherein the moving mechanism comprises a translation plate, a second motor and two moving assemblies. The cleaning mechanism comprises a lifting assembly, a lifting table and two circular rings. Themoving assembly comprises a rotating shaft, a gear, a rack and a limiting unit; an inner ring, a plurality of cleaning brushes and a plurality of telescopic units are arranged on the inner side of the circular ring, According to the electrolysis flotation equipment for wastewater treatment, the cathode is driven to rotate through the first motor; the cathode is moved through the moving mechanism,so that the moving range of the hydrogen bubbles is enlarged, the purification range of the equipment is expanded, dirt on the surfaces of the cathode and the anode is removed through the cleaning mechanism, the cathode and the anode can be in full contact with wastewater, the electrolytic reaction rate is guaranteed, and the practicability of the equipment is improved.

Description

technical field [0001] The invention relates to the field of water purification equipment, in particular to an electrolytic air flotation equipment used for wastewater treatment. Background technique [0002] Electrolytic air flotation refers to the introduction of direct current into the sewage, and a large number of tiny hydrogen bubbles with a diameter between 18 and 90 microns are generated on the surface of the cathode in the sewage. The hydrogen bubbles adhere to the small suspended particles in the wastewater, forming an overall density smaller than water. The "bubble particle" complex, the suspended particles float to the water surface together with the air bubbles, forming foam scum, so that the suspended solids in the water can be separated, a water treatment method, because the electrolytic air flotation has simple equipment, convenient management, and resource saving , good effect, etc., the electrolytic air flotation device is an ideal substitute for the traditi...

AI Technical Summary

Problems solved by technology

[0003] However, during the operation of the existing electrolytic air flotation device, since the position of the electrode remains unchanged, and the hydrogen bubbles are mainly generated near the cathode, the activity and action range of the hydrogen bubbles are limited, and the bubbles mainly act on the sewage around the cathode. , and for the sewage in other locations, due to the long distance, the purification range is limited. Not only that, in the process of electrolysis, the surface of the electrode is easy to scale, which affects the contact between the electrode and the sewage, which not only increases the power consumption, but also reduces The generation of air bubbles around the electrodes reduces the practicability of existing electrolytic air flotation devices
