A kind of copolymerization floating sink and water purification method

Abstract

The copolymerization floating-settling tank of the present invention includes a multi-channel folded-plate copolymerization flocculation tank for realizing coagulation and copolymerization of flocs and micro-bubbles; Separation, sedimentation of sedimentary flocs that cannot be air-floated; and a dissolved air system connected to the water outlet of the floating and sinking tank. The flocculation tank and the floating sink tank provide backflow high-pressure dissolved air water. The copolymerization floating-sinking tank will add backflow high-pressure dissolved air water three times, and organically combine it with the flocculation process to create a copolymerization environment for micro-bubbles and flocs. Problems such as low adhesion efficiency, unsatisfactory capture effect, and unstable adhesion of foam flocs make the coagulation, air flotation, and sedimentation processes organically combined and integrated to deal with high algae, low turbidity, and sudden high turbidity in reservoir water quality Has outstanding advantages.

Description

technical field [0001] The invention relates to a copolymerization floating sink and a water purification method, belonging to the technical field of water treatment. Background technique [0002] At present, the problem of reservoir water pollution is becoming more and more prominent, among which algae pollution is particularly serious. At present, the reservoir water tends to have the characteristics of high algae in summer, low temperature and low turbidity in winter, and high turbidity in summer rainy season. As the degree of eutrophication of water sources increases year by year, algal blooms are becoming more and more serious, especially in spring and autumn when the temperature changes greatly, algae outbreaks occur from time to time, posing a certain threat to the operation of water plants and water supply safety. The density of algae is small, and it is difficult to effectively remove it by traditional coagulation, sedimentation, and filtration processes, which bri...

Problems solved by technology

[0006] In order to overcome the deficiencies of the above technologies, the present invention provides a copolymerization floating-sinking tank and a water purification method. In the copolymerizing floating-sinking tank, the reflux high-pressure dissolved air water is added three times, and the flocculation process is organically combined to create micro-bubbles and flocs. environment, the microbubbles adhere to the middle of the flocs, and the microbubbles participate in the coagulation process to play a coagulation effect. For problems such as low particle adhesion efficiency, unsatisfactory capture effect, and unstable adhesion of foam and floc, the coagulation, air flotation, and sedimentation processes are organically combined and integrated to deal with high algae, low turbidity, and sudden high turbidity. Reservoir water quality has outstanding advantages
