Technical Field
The utility model belongs to the technical field of sewage treatment's technique and specifically relates to an add throwing ozone ultrafiltration system for improving membrane flux, in particular to system architecture.
Background
Under the current call for sustainable development strategy, the pollutants produced by industrial and agricultural production are highly valued. Among them, sewage is undoubtedly the most common pollutant. The hot process for treating sewage at present stage is a membrane treatment process. The membrane separation technology has the functions of separation, concentration, purification and refining, and has the characteristics of high efficiency, energy conservation, environmental protection, simple molecular level filtration and filtration process, easy control and the like, so the membrane separation technology is widely applied to various production activities. However, microorganisms are propagated on the membrane surface, which causes a decrease in membrane flux, and further causes various problems such as a decrease in membrane treatment efficiency and an increase in energy consumption. Therefore, in order to deal with the problem of microbial growth, it is necessary to establish a treatment method having an effect of removing microorganisms. The method of adding ozone and catalyzing the decomposition by ultraviolet light provides a good breakthrough for solving the problem, and obtains good effects in the application of inhibiting the growth of microorganisms and improving the membrane flux.

Detailed Description
The invention will be further described with reference to the accompanying drawings.
The utility model discloses an add throwing ozone ultrafiltration system for improving membrane flux, it lies in different from prior art: the nitrogen-gas separator comprises a nitrogen-gas separator 1, wherein a gas outlet of the nitrogen-gas separator 1 is connected with a gas inlet of an ozone generator 2 through a pipeline, a gas outlet of the ozone generator 2 is connected with a gas inlet of a mixing tank 3 through a pipeline, a plurality of ultraviolet lamps 4 are equidistantly and parallelly distributed on the tank wall of the mixing tank 3, a protective net cover is arranged on the outer cover of each ultraviolet lamp 4, a water outlet of a water inlet tank 5 is connected with a water inlet of the mixing tank 3 through a water inlet pipeline 6, and a water outlet of the mixing tank 3 is connected with a water inlet of a ceramic.
The nitrogen in the air is separated in a separator, the remaining majority of the gas is oxygen, after which the oxygen is converted to ozone by an ozone generator. The sewage is mixed with ozone, and the mixture is irradiated by ultraviolet light and then is introduced into the ceramic membrane. The purpose of adding ozone is to inhibit the growth of bacteria on the surface of the membrane, and ultraviolet irradiation is usedIs to promote O3Decompose into oxygen and oxygen ions, increase O3The sterilization effect can inhibit the growth of bacteria and increase the membrane flux. Thereby maintaining the processing efficiency and energy consumption of the system.
In specific implementation, a plurality of branch aeration pipes 8 are laid at the bottom of the mixing tank at equal intervals and distributed in parallel, a main air pipe 9 is laid at the bottom of the mixing tank, one end of each branch aeration pipe 8 is vertically connected and communicated with the main air pipe 9, the main air pipe 9 and the branch aeration pipes 8 are positioned on the same horizontal plane, exhaust holes are distributed on the upper surface of each branch aeration pipe 8 at equal intervals, and a hemispherical aeration head 10 is fixed at each exhaust hole.
When the ultraviolet lamp cleaning device is specifically implemented, a washing spray head 11 is hung right above each ultraviolet lamp 4, the washing spray head 11 is connected with a water purification pipeline, and a booster pump is arranged at the position of the water purification pipeline and used for cleaning the ultraviolet lamps 4.
The foregoing is a more detailed description of the invention, taken in conjunction with the accompanying preferred embodiments, and it is not intended that the invention be limited to the specific embodiments described above.
