Description
Technical Field
The utility model belongs to the technical field of sewage treatment, in particular to super nanometer bubble circulation ozone sewage treatment plant.
Background
In the existing sewage treatment process technology, the anaerobic membrane bed is a high-efficiency sewage anaerobic treatment process, and has the advantages of fast start, difficult sludge loss, capability of selecting fillers made of different materials and the like. The aeration biological filter tank is also a high-efficiency sewage aerobic treatment process, and has the greatest advantage of integrating the functions of biological oxidation and suspended solid interception, thereby saving a secondary sedimentation tank. The method has the disadvantages that the sewage treatment reaction time in the anaerobic treatment process is longer, and a large-area treatment tank is needed, so that the problem that the system occupied area of the sewage tank adopting the treatment process is lower while the treatment capacity is achieved is caused; the aerobic treatment process has the defects of high requirement on the suspended matter concentration SS of inlet water, large head loss and need of periodic back washing. In addition, the COD level of the sewage in the two processes is easy to generate large fluctuation, so that the process and the result of sewage treatment become uncontrollable.

Obviously, the sewage treatment system adopting the process has the defects of an anaerobic treatment process and an aerobic treatment process at the same time. Namely, under the conditions of large building occupation area, lower treatment capacity and higher requirements on sewage pretreatment, various agents need to be added into the sewage for adjustment, so that the treatment period is prolonged, the operation cost is increased, and the sludge production is increased.
Therefore, how to adopt the two processes and overcome the defects of the two processes, how to improve the treatment efficiency of the system, reduce the operation cost, save the floor area of the building and make the sewage treatment process more stable and controllable becomes a technical problem which is generally required to be solved in the industry.
In addition, in the sewage treatment process in the prior art, nano bubbles and ozone water are applied. As is well known in the industry, the bursting of the nano bubbles can break the molecular chemical bonds of organic matters such as oil stains and the like, thereby realizing the degradation effect. And the smaller the bubbles, the more remarkable the effect. In addition, the nano bubbles also have a remarkable effect on removing colloids in sewage. Ozone is a substance with strong oxidizing property, and can effectively degrade organic matters in sewage through advanced oxidation reaction.
However, due to technical limitations, nanobubbles of smaller diameter are difficult to generate; ozone gas is difficult to directly apply to sewage treatment, ozone water is difficult to prepare, and the effective time is short (the ozone concentration in water is 6.25 x 10)-3mg/L, and the half-life period is 5-30 minutes). Leading to the difficulty of large-scale application of the two methods in the field of sewage treatment.
How to better apply the two technologies in sewage treatment, give play to the characteristics of the technologies, and innovate the existing sewage treatment process and system, becomes the focus of general attention in the field.

The super nano bubbles are generally used in the sewage pretreatment stage, the ozone water is generally used in the sewage advanced treatment, and in short, under the prior art condition, the two can not be used simultaneously.
(2) The ozone water used for treating sewage of the utility model is derived from sewage and acts on the sewage (the ozone water is prepared from the sewage and is unavailable under the prior art condition). The prior method is that firstly, an ozone generator is used for preparing ozone, the ozone is directly introduced into the sewage to be treated, or the ozone generator prepares ozone water from clear water and then the ozone water is added into the sewage to be treated; however, the process of preparing ozone in the prior art has high risk, high corresponding facility cost and very low efficiency. Compared with the prior method, the utility model is more convenient, safe and economical.
Compared with the prior art, the utility model has the advantages of it is following and beneficial effect:
1. the technical proposal of the utility model adopts the super nano bubble generator to generate the super nano bubble to cooperate with the ozone generation head to electrolyze and generate ozone water to efficiently degrade the sewage solution, thereby degrading the organic pollutant in the sewage solution into carbon dioxide (CO)2) And water (H)2O) and waste residue which is difficult to dissolve in water, wherein the waste residue is uniformly collected by a waste residue collector under the action of self weight.

Adopt the utility model discloses the device carries out super nanometer bubble circulation ozone sewage treatment's technology, compares with prior art, has following advantage and beneficial effect:
1. high-concentration ozone water is adopted to carry out advanced chemical reaction on organic matters in the sewage, and the stability of COD value can be maintained on the basis of reducing the COD value of the sewage.
2. Other chemical agents are not required to be added in the whole process, so that the sludge production is greatly reduced. In the traditional sewage treatment process, chemical agents such as caustic soda, polyaluminium chloride and the like are added in the coagulation air flotation process, and the chemical agents can finally become and increase the yield of sludge. The process does not need to additionally add the medicaments in the sewage treatment process, and the process generates less sludge, so that the sludge generation amount of the whole process is effectively controlled; meanwhile, the pollutants in the wastewater are strongly oxidized by the operation of the advanced oxidation system, so that the organic pollutants are fully oxidized into carbon dioxide (CO2) And water (H)2O), and simultaneously separating part of pollutants which are difficult to dissolve in water out of the water body through waste residues; thereby reducing the addition amount of chemical agents or not adding the chemical agents and reducing the output of the sludge.
3. Compared with the traditional sewage treatment process, the process has strong sewage treatment capacity and short sewage treatment time, and can replace a biochemical system consuming time and materials. The main process of the traditional sewage treatment process is to degrade organic pollutants by using anaerobic and aerobic biochemical reactions. The metabolism speed of the microorganisms and the metabolism of the microorganisms are easily influenced by the external environment, so that the sewage treatment capacity is limited and the treatment speed is low, and the treatment capacity of a sewage treatment system is indirectly limited and the treatment process is long in time consumption. In the process, the organic matters are degraded by adopting the super nano bubbles and the high-concentration ozone water, so that the degradation efficiency is high, the efficiency is not influenced by water conditions, and the superiority of the process in the aspects of treatment capacity and treatment time consumption is ensured.
4. The process has strong combinability with other sewage treatment processes, and equipment using the process and corresponding treatment capacity have strong expansibility, and the process can be used as a module to be conveniently combined with various sewage treatment equipment. In addition, the process equipment is suitable for treating various kinds of sewage, and can achieve the treatment effect by increasing the number of ozone generating heads or prolonging the treatment time aiming at the sewage with different water quality conditions.
5. The system applying the process has the advantages of flexibility in structure, adaptability to various space and environmental conditions, low design requirement on the system and land space saving, and is a high-efficiency and low-cost sewage treatment process.
6. In addition, the super nano bubbles adopted in the process generate the conductive nano diamond material on the plane by the bubbles, the super nano bubbles with the diameter less than 1 mu m can be prepared, and in the process of separating oil stains and colloidal pollutants by utilizing the super nano bubbles, the huge destructive power generated by the bursting of the bubbles can destroy molecular chemical bonds so as to decompose the super nano bubbles into other substances. Can efficiently remove oil stains, colloid pollutants and other organic pollutants in the sewage without adding other reagents. Because the use amount of reagents used for removing oil stains and colloids is reduced, the production amount of sludge in the process is greatly reduced, sewage with better water quality conditions is provided for the subsequent treatment process, and the treatment effect of the system is ensured.
7. Can replace a biochemical system and has the advantage of stabilizing the COD of the sewage. Microorganisms in the traditional biochemical system have certain requirements on the stability of COD, and the ecological system has the danger of collapse under the condition of unstable COD. The sewage treatment effect produced by the method can reach or even exceed that of a biochemical system. In addition, the stability of the system is improved, and the continuous sewage treatment capacity of the system is easier to maintain.
