Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a novel ozone oxidation sewage treatment equipment, which belongs to the field of environmental protection. Background technique [0002] my country is a country with relatively poor water resources, and water resources have become one of the main factors restricting social and economic development. However, with the rapid development of my country's social economy and the acceleration of urbanization, a large amount of industrial and domestic sewage has been produced. If these sewage can be treated and recycled, not only can the environmental pollution caused by sewage discharge be avoided, but also for the alleviation of The problem of urban water shortage is of great significance. [0003] Among many sewage treatment technologies, ozone oxidation was first applied in Dutch waterworks in 1893. This technology uses the oxidative properties of ozone to degrade easily oxidizable subst...

Problems solved by technology

Wherein: Chinese patent (ZL96242062.X) discloses a kind of tubular sewage treatment device, and the pipe body of this processor has helicoid, and there is ultraviolet emission tube between helical piece and helical piece, when sewage flows through pipe body, passes through helical piece Stirring is mixed with ozone, and sewage treatment is realized under the action of ultraviolet rays emitted by the ultraviolet emitting tube. The disadvantage is that the axial mixing of ozone and sewage in the tube body is not uniform, so the quality of sewage treatment will be unstable. Turbulent kinetic energy will damage the ultraviolet emission tube and affect the continuous operation of the processor; another Chinese patent (ZL96242065.4) discloses a tray type sewage processor, although the oxidation efficiency of ozone in this patent has been improved compared with the absorption tower However, the mixing uniformity of ozone and sewage is still limited. The arrangement of multi-layer trays in the processor makes the sewage and ozone flow through each layer of trays and will lose a lot of energy under the action of resistance, resulting in higher operating costs. In addition, the relatively complex tray structure is not conducive to the manufacture and maintenance of the equipment; Chinese patent (ZL01263386.0) also discloses a gas-water mixing device in ozone sewage treatment, which consists of a jet mixing chamber and a vortex mixing chamber. The water and sewage are mixed in the jet mixing chamber and the vortex mixing chamber successively, and redox reactions occur to achieve the purpose of sewage purification. The disadvantage is that the structures of the jet mixing chamber and the vortex mixing chamber are relatively complicated, especially in the jet holes of the jet mixing chamber. The rifling structure similar to that in the rifle chamber is processed, which makes the manufacturing cost of the equipment high and is not suitable for large-scale sewage treatment industry applications
