Description

TECHNICAL FIELD

[0001] The utility model relates to wastewater treatment technical field, concretely relates to a kind of ozone micro-bubble treatment high concentration wastewater equipment. BACKGROUND

[0002] With the continuous improvement of people's living standards and the acceleration of urbanization, the production of municipal solid waste is also increasing year by year, and the current municipal solid waste is growing at a rate of 9% to 10% per year, which brings the demand for supporting treatment of landfill leachate is also growing, landfill leachate and general sewage are different, for example, COD concentration is particularly high, ammonia concentration in landfill leachate is high, the proportion of microbial nutrients in landfill leachate is seriously imbalanced, water quantity and quality change greatly, such sewage is generally called high concentration organic wastewater, high concentration organic wastewater has always been a recognized technical problem in the field of wastewater treatment, so far, although processes such as leachate recharge, land treatment, physical and chemical treatment, reverse osmosis, evaporation treatment, advanced chemical oxidation and biological reactor landfill site have appeared, but there are few mature equipment and processes, there is no continuous production process, ozone dosage is large, utilization rate is low, process is complicated, cost is too high to popularize, and it is easy to overflow ozone to affect the working environment, occupies too much area and has low efficiency, takes too long time and the reaction is unstable.

[0003] Among the current many high concentration wastewater treatment methods, ozone micro-bubble treatment shows more obvious advantages, ozone is a strong oxidizing agent, its oxidation-reduction potential is quite high, second only to fluorine element, when applied to high concentration wastewater treatment, ozone can actively oxidize various organic matter in wastewater, in this process, macromolecular organic matter will be gradually decomposed and converted into small molecular organic matter, and in ideal conditions, it can even be directly mineralized into carbon dioxide and water, thereby greatly reducing the content and harm of organic matter in wastewater, realizing the purification treatment of wastewater, ozone micro-bubble treatment method mainly relies on ozone micro-nano bubble generator to generate ozone micro-bubbles in wastewater, the diameter of these micro-bubbles is usually in the range of tens of microns to hundreds of microns, because of its small diameter, micro-bubbles have large specific surface area, compared with ordinary bubbles, the contact area between it and wastewater has been greatly improved, which makes ozone in micro-bubble state can more fully contact and react with organic matter in wastewater, thereby improving the treatment effect.

[0004] However, the existing ozone micro-nano bubble generator has certain limitations in the wastewater treatment process. The position of the ozone micro-bubbles generated in the wastewater is often fixed, and in this case, the micro-bubbles will rise vertically in the wastewater, which results in a relatively single movement trajectory. During the rising process, the micro-bubbles are difficult to effectively contact with the water body at the edge position of the wastewater. The organic matter in the wastewater at the edge position cannot be effectively oxidized in time, which reduces the efficiency of the wastewater treatment and makes it difficult to achieve the ideal level of the final treatment effect, which is not conducive to the efficient development and target achievement of high-concentration wastewater treatment work.
