Embodiment 1

[0028] see figure 1 , figure 2 and image 3 , the activation doser 3 is provided with a water injector 7, an activation reactor 8 and an activation mixer 11, the upper end of the activation reactor 8 communicates with the water injector 7, and the lower part of the activation reactor 8 communicates with the activation mixer 11 and is provided with Drainage pipe 9, activation mixer 11 is provided with chlorine dioxide aqueous solution feed pipe 12 and activator feed pipe 13, and chlorine dioxide aqueous solution feed pipe 12 and activator feed pipe 13 pass through first metering pump 2, activator feed pipe 13 respectively. The second metering pump 4 communicates with the chlorine dioxide aqueous solution storage tank 1 and the activator storage tank 5 , and the activation mixer 11 is provided with a blowdown pipe 10 .

[0029] see figure 1 , figure 2 and image 3 , the first metering pump 2 pumps the chlorine dioxide aqueous solution that is 2% by mass in the chlorine di...

Embodiment 2

[0031] Embodiment 2: bactericidal effect

[0032] A, the chlorine dioxide aqueous solution that is 5% by mass content and the hydrochloric acid that is 10% by mass content are added in the activator by 1: 1 volume ratio and mix and be mixed with;

[0033] B. The water injector adds the chlorine dioxide disinfectant solution formed by the chlorine dioxide aqueous solution under the action of hydrochloric acid into the flowing sewage.

[0034] To kill Staphylococcus aureus, add chlorine dioxide at a concentration of 1mg / L.

[0035] The disinfection time is 60 seconds, and the sterilization rate can reach 99.99%

[0036] Kill Escherichia coli, add chlorine dioxide concentration 0.15mg / L,

[0037] The disinfection time is 300 seconds, and the sterilization rate can reach 99.90%.

Embodiment 3

[0038] Embodiment 3: to the removal of manganese

[0039] This method can oxidize divalent manganese to tetravalent manganese, so that it can form manganese dioxide which is insoluble in water. The removal rate of manganese is 80-95%, and the dosage of chlorine dioxide is 5.0mg / L.

Abstract

The invention discloses a rapid purification and disinfection method for wastewater. The method comprises: A. adding 2-5 wt.% chlorine dioxide aqueous solution and 4-10 wt.% activator at a volume ratio of 1:1 into an activation device to obtain a mixture; B. adding the chlorine dioxide disinfection solution obtained from step A by water-jet into the flowing wastewater until 0.5-5 mg/L of chlorine dioxide in the wastewater, and maintaining no less than 15 minutes. The invention also discloses a device for the method. The method has high efficiency and good effect in rapid purification and disinfection of wastewater. The device has the advantages of simple structure, convenient manufacture and reliable performance.

Description

technical field [0001] The invention relates to a method for disinfecting sewage, and also relates to a device for realizing the method. Background technique [0002] All kinds of domestic sewage, industrial sewage, and medical sewage contain various bacteria and viruses, which need to remove odors, as well as reducing ions such as divalent iron ions, divalent manganese ions, and negative divalent sulfur ions, as well as mercaptans and phenols. Compounds, cyanides, organic sulfides, reduce COD, BOD value, bleaching and decolorization treatment is required for printing and dyeing wastewater. At present, there is a treatment method that uses chlorine dioxide disinfectant as a disinfection and purification agent, and adds it to the sewage for treatment. However, the chlorine dioxide produced by the current chlorine dioxide disinfectant generator is unstable, low in purity, low in sewage treatment efficiency, poor in effect, large in equipment size, many in failure, prone to ex...
