Embodiment 1

[0071] A double internal circulation water processor combining photocatalysis and aerobic organisms, including a reaction cylinder 1, a three-phase separator 2 and a stripping cylinder 3 are arranged at the axial position of the reaction cylinder from top to bottom, and at the top of the reaction cylinder 1 An air outlet pipe 4 is provided to be connected to the three-phase separator 2, a water outlet 5 is provided on the upper wall of the reaction cylinder 1, and a water inlet pipe 6 and the bottom end of the stripping cylinder 3 are arranged at the bottom of the reaction cylinder 1 In contrast, an aeration disc 7 is arranged around the bottom of the stripping cylinder 3, and the aeration disc 7 has micropores for the sewage to flow down. The aeration disc 7 divides the reaction cylinder 1 into a settling zone 1-1 and a reflux zone 1- 2. Two parts; an ultraviolet light source 8 and titanium dioxide light particles 9 are arranged in the airlift cylinder 3; aerobic activated slu...

Embodiment 2

[0075] A kind of waste water method that utilizes water processor as described in embodiment 1 to process certain textile factory in Shandong area, comprises steps as follows:

[0076] (1) Turn on the ultraviolet light source 8, and pump the sewage into the airlift cylinder 3 along the water inlet pipe;

[0077] (2) The sewage is uniformly mixed with the light titanium dioxide particles 9 in the airlift drum 3, and under the irradiation of the ultraviolet light source and the catalysis of titanium dioxide, the refractory organic matter in the sewage is degraded into a biodegradable compound; the sewage rises To the three-phase separator: the gas is discharged along the gas outlet pipe; the light particles of titanium dioxide are blocked back into the stripper 3 by the three-phase separator; the sewage is returned to the settling zone 1-1 of the reaction cylinder;

Abstract

The invention relates to a double-internal circulating water treatment device capable of combining photocatalysis and aerobe, which comprises a reaction tube, wherein a three-phase separator and a stripping tube are arranged along the axial direction of the reaction tube from top to bottom; the top of the reaction tube is provided with an air outlet pipe which is connected with the three-phase separator; the tube wall at the upper part of the reaction tube is provided with a water outlet; the bottom of the reaction tube is provided with a water inlet pipe opposite to the bottom end of the stripping tube; the bottom of the stripping tube is provided with an aeration disc in a surrounding way; the aeration disc is provided with a micropore, and sewage can flow down through the micropore; the reaction tube is divided into a depression area and a recirculation area by the aeration disc; the stripping tube is internally provided with an ultraviolet light source and titanium dioxide light particles; and aerobic active sludge is filled in the depression area of the reaction tube. The invention also relates to a method for treating the sewage by using the water treatment device. According to the invention, a photocatalysis technology and a double-internal circulating structure are adopted, thus not only improving the water treatment effect, but also achieving the aims of saving resource and reducing the maintenance cost.

Description

technical field [0001] The invention relates to a dual internal circulation water processor combined with photocatalysis and aerobic organisms and a working method thereof, belonging to the technical field of sewage and wastewater treatment equipment. Background technique [0002] In sewage and wastewater treatment, treatment equipment and technology are very important. The quality of treatment equipment and treatment technology directly affect the effect of sewage and wastewater treatment. The various water treatment equipment and technologies currently used are all for specific For sewage and wastewater, its treatment effect can basically meet the discharge requirements, but these water treatment equipment have certain limitations in the use process, and they must be greatly improved if they need to be popularized. Moreover, the use of existing water processors to treat complex and difficult-to-biodegradable sewage and wastewater requires the deployment of various chemical...
