Problems solved by technology

The mud deposited at the bottom of the tank will be carried to the water outlet with the water flow, reducing the removal efficiency of organic matter and suspended matter in the effluent, and affecting the normal operation of the ozone air flotation device
Limited by the existing dissolved gas technology, the ozone generated by the ozone generator is wasted to a large extent
At the same time, in order to ensure its air flotation effect, the vertical flow ozone flotation device makes its height too high, which causes a lot of inconvenience to processing, installation and debugging

Abstract

The invention discloses a combined ozonization-air flotation integrated device. The device comprises a coaxial cylinder, a middle cylinder and a central cylinder. The cylinder and the central cylinder share the bottom. The cylinder and the middle cylinder share the top. The middle cylinder is arranged on support channel steel between the cylinder and the central cylinder. The top of the central cylinder is located in the middle cylinder. The top of the central cylinder is open. The upper part of the cylinder is provided with a drainage pipe. The top of the cylinder is provided with an inner cylinder exhaust pipe and a slag discharging pipe. The upper part of the middle cylinder is provided with an outer cylinder exhaust pipe. The lower part of the central cylinder is connected to a water inlet pipe, a gas-containing water inlet pipe and a connection inner cylinder emptying dredge pipe. An annular aeration pipe with an aeration inner thread head is arranged in the lower part between the cylinder and the middle cylinder. The annular aeration pipe is connected to an air inlet pipe. The lower part of the cylinder is connected to a connection outer cylinder emptying dredge pipe. The device has a three layer structure, realizes partitioning ozonation, air floatation separation and automatic slagging and has the advantages of fast installation, simple operation and high treatment efficiency.

Description

technical field [0001] The invention belongs to the technical field of sewage / wastewater, relates to the advanced treatment of sewage / wastewater, and in particular relates to a composite ozone air flotation integrated device. Background technique [0002] Ozone is a lively small molecule with strong oxidizing properties, and its redox potential is 2.07V, second only to fluorine. Ozone is widely used in water treatment and sewage treatment of slightly polluted source water. Air flotation has the characteristics of efficient separation of suspended solids in water, simple operation and low operating cost. The combination of the two and the synergistic use of the ozone oxidation characteristics and the air flotation separation characteristics create the ozone air flotation technology. In the actual application process, because the equipment has various pipelines such as water inlet, chemical inlet, ozone air inlet, drainage, exhaust, and slag discharge, and has multiple funct...
