Description
Technical Field
The utility model relates to a device for efficiently treating domestic sewage by using ozone.
Background
The treatment mode of domestic sewage generally combines three major technical means of biodegradation, chemistry and physical filtration. Among them, the use of ozone gas for the decolorization, deodorization, disinfection and decomposition of organic substances in domestic sewage is a well established conventional process. The ozone gas has the greatest benefit of environmental protection, because the ozone gas can be naturally decomposed into oxygen in the atmosphere, and meanwhile, the ozone gas has stronger oxidation activity than other common disinfection products, such as hydrogen peroxide, so that the ozone gas has excellent sewage purification conditions. However, since the artificially generated ozone gas needs to consume electric energy, and how to bring the ozone gas into domestic sewage and make ozone molecules, hydrogen and oxygen radicals generated by the ozone molecules and substances to be decomposed effectively contact with each other in time to achieve the decomposition purpose, the process has an efficiency problem because the ozone molecules, the hydrogen and the oxygen radicals in the water are in unstable states and are reduced into water and oxygen within a certain time, and if the ozone molecules, the hydrogen and the oxygen radicals are reduced before encountering organic substances (substances to be treated), the ozone generated only by consuming electric energy is wasted, which causes the problems of high energy consumption and slow treatment speed. The prior art ozone treatment domestic sewage device directly injects air containing ozone gas into a container containing sewage, so that the gas is contacted with organic matters in the sewage to generate decomposition of the organic matters. However, since the gas injected into the wastewater is always in the form of bubbles, the decomposition reaction can only occur on the surface of the bubbles, and the residence time of the bubbles in the wastewater container is very short, because the gas quickly floats on the liquid surface and then immediately breaks down, which causes the problems of low ozone gas utilization and high energy consumption. The vortex pump with the gas injection device can enable gas injected into liquid to appear in the form of bubbles with micron-sized diameters, and further effectively prolong the detention time of the gas in the liquid. This method has two disadvantages: 1. the equipment investment cost is high, and the energy consumption of the equipment is large. 2. The flow rate of gas injection and the diameter of the bubbles are in a proportional relationship, and when the diameter of the bubbles becomes smaller, the injection amount of the gas becomes smaller, so that when the total amount of the reaction substance becomes smaller, the reaction efficiency naturally decreases.
