Description
Technical Field
The invention belongs to the technical field of municipal drainage, and particularly relates to a photocatalytic reaction system for reducing pollutants in a drainage pipe network.
Background
The drainage pipeline is an engineering facility for collecting and conveying urban domestic sewage, industrial wastewater and rainwater. In recent years, with the acceleration of the urbanization process of China, the number and scale of the construction of drainage pipelines are increased year by year. Such as: in the thirteen-five period, the offshore city has the matched drainage pipeline of about 100km in the central urban area and the newly-built drainage pipeline of about 310km in the suburban area on the basis of the drainage pipeline with the total built length of about 9530 km. Increasingly perfect drainage pipeline systems provide convenience for conveying various sewage and rainwater in cities and towns, however, along with the gradual bulkiness of the drainage pipeline systems, the problems of water pollution, secondary disasters and the like of drainage pipelines are gradually obvious. Taking a split-flow rainwater pipeline as an example, under the background of repeated prohibition of rainwater and sewage mixing, random discharge of carwash gear sewage and large amount of initial rainwater surface source pollution, the rainwater pipeline becomes a collection place of a plurality of sewages, so that the black and odorous problems of rivers and lakes are frequently caused.
The advanced oxidation technology is an electrochemical water purification technology which is environment-friendly, free of secondary pollution and extremely high in reaction efficiency, has various forms and various types, has the advantages of easiness in implementation, simplicity and convenience in operation, remarkable effect and the like, and is widely applied to the field of water treatment. The photocatalytic oxidation technology effectively stimulates the generation of active free radicals (reaction 1) such as hydroxyl free radical (OH) and the like in water through the catalysis of ultraviolet rays cooperating with a semiconductor photocatalytic material (generally an oxide of metal titanium (Ti)), and then degrades macromolecular organic matters into micromolecular substances through the addition, substitution, electron transfer, bond breaking and the like of the free radicals and organic compounds, even directly degrades the macromolecular organic matters into carbon dioxide (CO)2) And water (H)2O), mineralization is completed (reaction 2-4).
H2O+hν→·OH+·H(1)
R+·OH→ROH (2)
R+·OH→·R+H2O (3)
Rn+·OH→Rn-1+OH-(4)
It is worth mentioning that the light source used in photocatalytic oxidation technology is typically an ultraviolet lamp, which is capable of emitting ultraviolet light of a relatively short wavelength (λ < 400 nm). The ultraviolet ray can not only quickly denature protein so as to effectively kill almost all bacteria and pathogens in the sewage, but also generate direct photolysis effect on organic matters in the water body when the wavelength is short and the dosage is large (reaction 5-8).
R+hν(λ＜185nm)→R*(5)
R*→·R1+·CH2CH3(6)
·R1+hν(λ＜185nm)→·Ii(i＝1，2，…，n) (7)
·Ii+·Ii→P (8)
However, most of the existing photocatalytic oxidation technologies only focus on the synergistic effect of ultraviolet rays and photocatalytic materials, and there are few studies or cases that the disinfection and sterilization of ultraviolet lamps and the direct photolysis are considered in the process. The existing photocatalytic oxidation system is mostly limited to single photocatalytic oxidation, but neglects the direct photolysis and disinfection of ultraviolet. Therefore, if a novel photocatalytic system with multifunctional switching and combination of photocatalytic oxidation, ultraviolet direct photolysis and ultraviolet disinfection and sterilization can be developed and applied to the in-situ purification of the drainage pipeline, the pollution discharge load at the tail end of the drainage pipeline must be reduced, and the water pollution control capability and the water environment treatment level are improved.
