In the technological design of UV sterilizer, ideal situation is to make water body receive uniform ultraviolet dosage, can make the maximizing efficiency of UV sterilizer like this.Be under 100% the situation in the ultraviolet penetration coefficient of peripheral medium, the uitraviolet intensity relation that is square inverse that radially distributes reduces.For the second pond water outlet of general municipal wastewater treatment plant, the transmitance of sewage is generally 65% about every centimetre, and uitraviolet intensity can radially be the geometricprogression decay again.Under the effect of these two factors, the distribution in effective disinfection space of equipment of uitraviolet intensity is very inhomogeneous.And, in the process that quartz burner uses, near the filament of lamp tube ends uitraviolet intensity can sharply descend, and (horizontal configuration is because be arranged in parallel with water body, so it is little to the influence of water disinfecting that the intensity of two ends filament reduces, and the layout of vertical and tilting, the filament decay at two ends is very big to the influence of lamp body two ends water sterilization, and then influences whole sterilization effect).Therefore, improve the characteristic of current in the UV sterilizer, can improve sterilisation effect widely.
The variation of water level is very little to the distribution influence of disinfection by ultraviolet light dosage after the baffle plate setting of adopting aforesaid way, and the baffle plate setting of aforesaid way can allow the range of stage of channeltype ultraviolet equipment bigger.For rectilinear and tilting UV sterilizer, can also reduce widely in use because the influence of the sterilisation effect that near the rapid decay of the light intensity of tube filament causes, experimentation and conclusion are as follows:
Setting disinfection by ultraviolet light Module Design elevation of water surface is 100cm, and design disinfection by ultraviolet light dosage is 20mJ/cm
2, water level exceeds design water level 2.5cm (be that elevation of water surface is 102.5cm, surpassing the normal design water level is 2.5cm).As previously mentioned, the water of this 2.5cm (surpass normal design water level and flow 2.5%) (is lower than 5mJ/cm as calculated for low ultraviolet ray dosage district
2).In the microorganism emission standard of one-level A, require the content of colibacillus of excrement less than 1000/L, the colibacillus of excrement content of sewage can reach 10 in general SBR or the second pond water outlet (water inlet of sterilization equipment)
6-10
7When normal water level, disinfection by ultraviolet light 20mJ/cm
2Dosage can make the inactivation ratio of colibacillus of excrement arrive 4 more than the order of magnitude, the content that namely can satisfy the colibacillus of excrement of sterilization water outlet (is calculating in 500 of hypothesis/L) less than 1000/L.Yet the inactivation ratio in this water yield of 2.5% only has an order of magnitude, i.e. the content of water outlet reaches 10
5Individual/more than the L.The average content that can calculate the colibacillus of excrement in the water outlet now is as follows:
The average content of colibacillus of excrement=(100% * 500+2.5% * 100000)/102.5%=2927/L
Though only surpass the 2.5cm of ordinary water-level, this numerical value has substantially exceeded the emission standard of water outlet.Therefore, the effect of channeltype disinfection by ultraviolet light is very sensitive to the variation of water level.
If in apparatus for ultraviolet disinfection, adopt the method for above-mentioned increase baffle plate, make the water yield of this 2.5cm be in stagnant condition (improving hydraulic detention time widely) substantially or can flow through the zone of high ultra violet intensity fully, and then make the current of this part obtain 15mJ/cm
2More than the dosage, the average content that calculates the colibacillus of excrement of water outlet in this part according to the sterilization dynamics formula is 10000/L.The average content that can recomputate the colibacillus of excrement in the water outlet this moment is as follows:
The average content of colibacillus of excrement=(100% * 500+2.5% * 10000)/102.5%=731/L
Therefore, through increasing UV sterilizer behind the baffle plate when water outlet surpasses ordinary water-level (through the actual observation record, change of level can not surpass the design height of the upper fixed baffle plate of three kinds of mode of operation substantially in the channel), still can reach the requirement of one-level A water outlet.Described fixed dam is except above-mentioned effect, UV sterilizer at rectilinear and tilting arranges upper and lower fixed dam according to the aging situation that causes this zone uitraviolet intensity sharply to be decayed of lamp tube ends, make that also (quartz burner two ends) keep not flowing current substantially in the ageing equipment zone, when stablizing sterilisation effect, improve the equipment life cycle, saved cost.
The utility model provides a kind of apparatus for ultraviolet disinfection that possesses stable baffle arrangement, and this apparatus structure is simple, can solve channeltype ultraviolet equipment sterilisation effect stability problem, improves the efficient of disinfection by ultraviolet light.
Above-described only is preferred embodiment of the present utility model; institute is understood that; the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; and be not used in and limit protection domain of the present utility model; all any modifications of within thought of the present utility model and principle, making, be equal to replacement etc., all should be included within the protection domain of the present utility model.
