Description
Technical Field
The utility model belongs to the water treatment field, in particular to a novel ozone oxidation's waste water treatment device.
Background
The advanced oxidation technology has incomparable advantages in the aspect of treating wastewater, such as biological methods, physical methods and the like, and has the advantages of high efficiency, deep treatment degree and the like. However, most advanced oxidation technologies have the disadvantages of large equipment investment, complex operation, high operation cost and the like, for example, a wet oxidation process needs to be operated under the conditions of high temperature and high pressure, and the equipment investment and the energy consumption are high; the fenton's reagent oxidation process is complex to operate and consumes large amounts of chemicals.
The ozone has strong oxidizing power in water treatment. It is known from the resonance structure of ozone molecules that the reason why ozone has strong electrophilicity is that 6 electrons exist around oxygen atoms located on both sides in the ozone resonance structure and the ozone exhibits positive electricity. Ozone, being extremely reactive, can cause it to self-decompose in water. When ozone oxidizes organic substances in water, unsaturated bonds in the organic substances are mainly oxidized. Because the product after ozone treatment only contains oxygen, ozone is widely applied to the field of wastewater treatment.
Although simple ozone oxidation can remove organic substances to a certain extent, ozone is difficult to further oxidize oxidized small molecular substances, so that simple ozone oxidation has a certain limitation on the mineralization degree of the organic substances. Currently known methods for increasing the efficiency of ozone oxidation are: adding catalyst and hydrogen peroxide, raising pH value, ultraviolet irradiation, etc. The process of promoting the ozone to be converted into hydroxyl radicals through specific conditions is catalytic ozone oxidation, and belongs to a high-grade oxidation process. Scientific research shows that: the capability of generating hydroxyl radicals and improving the capability of ozone for oxidizing organic matters can be obviously improved by adding a catalyst into an ozone system or cooperating with other processes.
The active carbon has a developed micropore structure and a huge specific surface area, and has strong adsorption capacity. In the water purification process, organic matters, inorganic matters, synthetic detergents, anionic surfactants and other active substances in water can be effectively removed. The activated carbon also has a catalytic effect, and the ozone is catalytically oxidized into hydroxyl radicals to finally generate oxygen, so that the concentration of dissolved oxygen in water is increased. The active carbon has many pores and large specific surface area, and can quickly adsorb soluble organic matters in water and enrich microorganisms in the water. The adsorption of the activated carbon to organic matters in water and the oxidative decomposition of microorganisms occur in succession, the oxidative decomposition of the microorganisms recovers the adsorption capacity of the activated carbon, and the adsorption of the activated carbon also enables the microorganisms to obtain rich nutrients and oxygen, which are mutually promoted to form a relatively stable state, so that a stable treatment effect is obtained, and the regeneration period of the activated carbon is greatly prolonged.
