Embodiment 1

[0048] A columnar processor with a UV lamp in the center, with a structure such as figure 1 As shown, a cylindrical reactor 1 is included, the bottom of the cylindrical reactor 1 is provided with a microporous aeration head 3, the aeration head 3 is connected with an external ozone generator, and the upper part of the reactor is provided with a water outlet and an air outlet 5 , the lower part is provided with a water inlet (not shown in the figure), and a UV lamp 2 is provided at the center of the reactor.

[0049] One UV lamp 2 is set at the center of the reactor at a 360° radiation angle, and the distance between the bottom of the UV lamp 2 and the aeration head 3 is 7 cm. The bottom end of the reactor is provided with a base, and the center of the base is provided with a circular hole that penetrates up and down. The aerator head is fixed on the upper part of the circular hole. The ozone inlet pipe 4 of the ozone generator penetrates into the circular hole and communicate...

Embodiment 2

[0051] A UV / O 3 The method for joint treatment of high-salt high-concentration active emerald blue textile wastewater, the method adopts the processor described in embodiment 1 to carry out, and the steps are as follows:

[0052] Adjust the pH of the active Cuilan K-GL textile wastewater to 10, pass ozone into the active Cuilan K-GL textile wastewater, and control the ventilation rate of ozone at 500mL min -1 , Turn on the UV lamp to preheat for 5 minutes, the wavelength of UV light is 254nm, use the UV lamp to irradiate the wastewater, and use ozone and UV to treat the active Cuilan K-GL textile wastewater for 56 minutes at the same time to achieve efficient degradation of organic pollutants.

experiment example 1

[0056] Change the amount of ozone in the treatment method of Example 2, and the effect of different ozone amounts on the ozone oxidation degradation activity Cuilan K-GL textile wastewater is as follows: figure 2 shown.

Abstract

The invention relates to a method for treating high-salt and high-concentration active emerald blue textile wastewater through combination of UV / O3. The method comprises the following steps: introducing ozone into active emerald blue K-GL textile wastewater by adopting a treater with a UV lamp arranged in the center, controlling the introduction amount of the ozone to be 0.5-3L.min<-1>, turning on the UV lamp, irradiating the wastewater by adopting UV, and conducting preheating for 4-6 minutes. The active emerald blue K-GL textile wastewater is treated for 32-56 min through ozone and UV at the same time, efficient degradation of organic pollutants is achieved, the ozone (O3) and ultraviolet lamp (UV) combined technology is adopted, the removal effect of the active emerald blue K-GL can be greatly improved by combining the UV with ozone at the UV power of 40 W, ozone is excited to generate multiple active substances, and organic matter is oxidized and degraded.

Description

Technical field: [0001] The present invention relates to a kind of UV / O 3 The invention discloses a method for combined treatment of high-salt and high-concentration active emerald green textile wastewater, which belongs to the field of advanced oxidation treatment of textile wastewater. Background technique: [0002] The textile printing and dyeing industry is one of the industrial sectors that consume a lot of water and discharge a lot of wastewater. According to statistics, my country's textile enterprises discharge 3 to 4 million tons of wastewater every day. Textile wastewater mainly has the following characteristics: (1) large amount of water: the pollution of wastewater is mainly organic pollution; (2) high concentration of pollutants: the pollutants in wastewater are mainly the second type of harmful substances; (3) most of them are Alkaline, high chroma; (4) The water quality changes greatly, and it is difficult for general wastewater treatment facilities to meet ...
