Embodiment 1

[0022] Such as figure 1 , image 3 , Figure 4 As shown, the ozone air flotation cycle treatment device includes a flocculation reaction tank 1, an air flotation tank 2 connected to the flocculation reaction tank 1 in turn, and a clear water tank 3; the top of the air flotation tank 2 is connected with a slag scraper 4 and an exhaust gas collection cover 5 in sequence; The collection cover 5 is connected to an ozone generator and a gas-liquid mixing pump 6 in turn through pipelines; the gas-liquid mixing pump 6 has a liquid inlet and a gas-liquid outlet, the liquid inlet is connected to the clear water pool 3, and the gas-liquid outlet is connected to the air flotation pool 2; the air flotation pool The bottom of 2 is provided with a plurality of horizontal tubes 7 and a plurality of vertical tubes 8; a plurality of horizontal tubes 7 are arranged in sequence, and at least one vertical tube 8 is communicated between adjacent horizontal tubes 7; any horizontal tube 7 or any ve...

Embodiment 2

[0025] Figure 2-4 As shown, the difference between this embodiment and Example 1 is that the flocculation reaction pool 1 is connected with a grid pool 15, and the grid pool 15 is connected with the sewage pool to be treated; an adsorption pool is connected between the flocculation reaction pool 1 and the air flotation pool 2 14. The adsorption pool 14 is provided with any one or more of activated carbon, montmorillonite, and medical stone; the adsorption pool 14 may also be provided with other devices with adsorption functions.

[0026] Figure 2-4 As shown, when the embodiment 1 and the embodiment 2 are in use, the sewage enters the grid pool 15 from the sewage pool to be treated and enters the flocculation reaction pool 1 after preliminary filtration, and is flocculated by the flocculant dosing machine and the coagulant dosing machine. After adding medicine in the reaction tank 1 to make the suspended solids and small particles in the sewage settle quickly, it enters the ...

Abstract

The invention discloses an ozone gas floatation circular processing apparatus, and mainly solves the problems, such as ozone pollution or waste of ozone resource due to an ozone gas floatation device in the prior art, and low utilization rate of ozone. The ozone gas floatation circular processing apparatus comprises a flocculation reaction tank, a gas flotation tank and a clean water tank which communicate with the flocculation reaction tank in order; the top part of the gas floatation tank is connected with a sludge scraper and a tail gas collection cover in order; the tail gas collection cover communicates with an ozone generator and a gas-liquid mixing pump in order through pipelines; the gas-liquid mixing pump is provided with a liquid inlet and a gas-liquid outlet, the liquid inlet communicates with the clean water tank, and the gas-liquid outlet communicates with the gas floatation tank. The problems such as ozone pollution or waste of ozone resource and low utilization rate of ozone are solved, and the apparatus has a practical value and a promotional value.

Description

technical field [0001] The invention relates to a device for treating sewage by using ozone air flotation, in particular to an ozone air flotation circulation treatment device. Background technique [0002] The organic compounds in the wastewater produced by the coal chemical industry are very complex. The COD in the comprehensive wastewater is generally about 5000mg / l, and the ammonia nitrogen is 200-500mg / l. The organic pollutants in the wastewater include phenols, polycyclic aromatic compounds, and nitrogen and oxygen. , sulfur heterocyclic compounds, etc., is a typical industrial wastewater containing refractory organic compounds; hospital sewage contains a large number of pathogenic microorganisms, parasite eggs such as roundworm eggs and various viruses such as hepatitis virus, tuberculosis bacteria and dysentery bacteria, etc. In addition, it also contains a large number of pollutants, of which organic matter accounts for about 60% of the total amount of pollution, an...
