Problems solved by technology

[0005] At the same time, the traditional dissolved air flotation process only introduces air to produce ordinary air microbubbles. Although it has achieved some good results in the treatment of low-temperature, low-turbidity, and high-algae water bodies, compared with water bodies with high organic matter However, the treatment effect is not very obvious, especially when dealing with some difficult-to-degrade organic matter and dissolved organic matter, with little effect

Embodiment 1

[0055] A biochar circulation type copolymerization air flotation tank water purification system is an integrated structure, including three-stage mechanical stirring copolymerization flocculation tank, ozone-biological activated carbon contact tank, bubble floc separation area, inclined plate sedimentation tank, sand filter, etc. Pool 13 and clear water pool 16, and ozonated dissolved air flotation device and release device, backwash device, powdered biological activated carbon recovery device and circulation system;

[0056] The three-stage mechanical stirring copolymerization flocculation tank, ozone-biological activated carbon contact tank, foam and floc separation zone, inclined plate sedimentation tank, sand filter tank, and clear water tank are connected horizontally in sequence, and the internal water flow is controlled through the tank walls between adjacent tank bodies; The ozonation dissolved air flotation device and release device are installed in parallel outside th...

Embodiment 2

[0067] A kind of method that adopts embodiment 1 biochar circulation type copolymerized air flotation tank water purification system to process common reservoir water, specifically comprises the following steps:

[0068] 1) The raw water enters the three-stage mechanical agitation copolymerization flocculation tank from the upper end of the coagulation 1 chamber 3 through the water inlet pipe 1, and at the same time, the coagulant is added with the raw water through the dosing pipe 2, and the water flows through the three coagulation chambers of the copolymerization mechanical flocculation tank in turn. , fully coagulate under the action of the mechanical shaft 6, and pass through the pool wall between the coagulation chambers to prevent the short flow of incoming water and ensure that the raw water and the coagulant are fully mixed. 3. Ozone-dissolved air water is released in room 5, and the water flow is ozonated while forming micro-nano bubbles, which plays a role in coagula...

Abstract

The invention relates to a charcoal circulation type co-coagulation flotation tank water purification system and method. Mechanical flocculation, dissolved air flotation and an inclined plate settling basin are organically combined so as to form copolymerization dissolved air flotation, and mechanical flocculation and dissolved air flotation are organically combined through a copolymerization dissolved air flotation process, so that the stability of bubble floc is improved. Ozone oxidation and biological activated carbon are organically combined, so that the decomposition ability of powder biological activated carbon on organic matters is greatly improved. Air flotation and ozone oxidation are organically combined, so that an ozone oxidation effect is greatly improved. Mechanical flocculation, copolymerization air flotation, the biological activated carbon and inclined plate settling are organically combined, so that under the conditions of effectively controlling the rotate speed, reducing the hydraulic loss and the like, an aquatic organic matter is removed, and the stable bubble floc is formed. The system provided by the invention is flexible in process and operation manner, can be beneficial for effectively reducing the operation cost, has the advantages of high adaptability to water quality change, high efficiency, convenience in operation and the like, and has a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of air flotation water treatment, and relates to a biochar circulation type copolymerization air flotation pool water purification system and method, in particular to a biochar circulation type copolymerization air flotation pool water purification system and method. Background technique [0002] In recent years, the problem of reservoir water pollution has become increasingly serious, and problems such as algae pollution and high organic matter content in water need to be solved urgently. At present, the water source of the reservoir presents the characteristics of high algae and high organic matter in summer and low temperature and low turbidity in winter. In recent years, as the degree of eutrophication in water bodies has increased year by year, the rate of algae proliferation has been increasing. Especially in spring and autumn when the temperature changes greatly, algae outbreaks have occurred from tim...
