Embodiment

[0020] A dissolved oxygen type water purification device, such as figure 1 shown. The water purification device is a multi-stage purification treatment device including a feeding part 101 , an air-water mixing part 102 , an ultrasonic mineralization reaction part 103 and an oxygen-enriched water collection tank 104 . The feeding part 101 is connected to the gas-water mixing part 102 through a pipeline. The gas-water mixing part 102 is connected with the ultrasonic mineralization reaction part 103 . The ultrasonic mineralization reaction part 103 is connected with the oxygen-enriched water collection tank 104 . The ultrasonic mineralization reaction unit 103 is connected to the dosing unit 104 .

[0021] The feeding part 101 is used for collecting sewage and oxygen of the water purification device. The air-water mixing unit 102 is used to realize coincidence and mixing of sewage to be treated and oxygen, so that the sewage to be treated can be saturated to supersaturated wi...

Abstract

The invention discloses a dissolved-oxygen type water purification device. The water purification device is a multilevel purification disposal device which includes a feeding part, a gas-water mixingpart, an ultrasonic mineralization reaction part and an oxygen-enriched water collecting box. Through arrangement of the structure of an air inlet in the device, air entering an air compression pipe has a high flow speed, and therefore a negative pressure phenomenon happens on both sides of a cylindrical cavity on the rear side of the air compression pipe. Through the negative pressure function, external air flows into the open cylindrical cavity formed between the air compression pipe and an air outlet, correspondingly the flow rate of the air entering the air outlet is further increased, andthat is to say that the air collection speed of an air pressure control box is increased. Meanwhile, because of an air spraying channel formed in a first ultrasound generator, molecular-scale or atomic-scale bubbles can be sprayed out, and sewage is pushed to rotate by means of gas dynamic at the same time, so that it is ensured that the granular bubbles can be uniformly distributed in the sewage, the oxygen dissolution rate of the sewage is further increased, and therefore the water disposal efficiency of the device is improved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a dissolved oxygen type water purification device. Background technique [0002] In the process of continuous expansion of urbanization scale and continuous improvement of industrialization in my country, a large amount of industrial sewage and domestic sewage that are difficult to treat will be produced. The main pollutants contained in sewage include organic pollutants, aerobic or anaerobic pollutants, and plant pollutants. Pollutants, toxic pollutants and radioactive pollutants, etc., the water quality is complicated, the toxicity is high, and the content of ammonia nitrogen and COD (chemical oxygen demand) is relatively high. Therefore, how to treat industrial sewage to meet the requirements of environmental protection is particularly important. important. Since the above-mentioned sewage usually contains a large amount of organic macromolecular substances, granular or dust-lik...
