Specific embodiment
Embodiment 1：The present embodiment constructs on-line continuous automatic filter and demonstrates its removal to turbidity in water sample.
Filter is made of four parts, is filter device, film rolling device, control device and water sample conveying device respectively, referring to Fig. 1
Filter device：By upper cover plate 1 (52mmx47mm), lower cover 3 (52mmx47mm), stepper motor 2 (for lifting and
Compress upper cover plate 1) and filter membrane 8 (nylon leaching film is rolled up, and 0.45 μm, wide 58mm, long 3m of aperture is rolled up on driven shaft) composition.Wherein,
Stepper motor 2 is set on the top of upper cover plate 1, and filter membrane 8 is arranged between upper and lower cover plates.
Upper groove 4 is equipped in the upper cover plate 1, diameter selectable range is 5-100mm, and the present embodiment takes 40mm, depth
Selectable range is 0.1-10mm, and the present embodiment takes 0.5mm, and upper groove side is equipped with a water inlet 5；The corresponding lower cover
Lower groove 6 is equipped in 3, recessed trench bottom is equipped with a water outlet 7；Lower groove 6 takes diameter 40mm, depth in the present embodiment
30mm, the upper cover plate 1 and 3 inner groovy of lower cover form a diameter 40mm, and depth is the cavity of 30mm, is filtered convenient for water sample.
Film rolling device：It is made of long 65mm, the active roller bearing 10 of diameter 5mm and driven roller bearing 9, stepper motor 11；Actively
Roller bearing 10 and driven roller bearing 9 are located at the two sides of upper and lower cover plates respectively；Active roller bearing 10 is connect with stepper motor 11, motor rotation
Active roller bearing 10 is driven to rotate, driven roller bearing 9 is then driven to rotate, the filter membrane section of contamination is rolled, pulls out clean filter membrane section.
Water sample conveying device：The connection of water inlet 5 one of upper groove 4 tilts water inlet pipe 14, the water outlet 7 of 4 stage of lower groove
Connect a vertically disposed outlet pipe 15.
Water inlet pipe 14 will be tilted to be placed in raw water, water-exit vertically pipe 15 is access to peristaltic pump, and during wriggling pump startup, raw water passes through
Water inlet pipe 14 enters filter device, is flowed out after filtering from outlet pipe 15, outlet pipe 15 can be access to water receiver or in-line analyzer.
Control device：Two stepper motors and a peristaltic pump are controlled using microcontroller, function is by C programmer reality
It is existing.The time that filter membrane section is replaced sets according to the muddy degree of water sample.During turbidity ＜ 40NTU, replacing construction 12min；It is turbid
When spending 40-75NTU, replacing construction 11min；During turbidity 75-150NTU, replacing construction 9min.
With the increase of filtering times, the diameter of filter membrane volume stain constantly increases, the filter membrane 8 licked under same time
Length is longer, and the filter membrane 8 for causing part clean is not using being licked.In order to solve the problems, such as this, employ one be commonly called as it is infrared
To the infrared sensor 13 of pipe.U-shaped infrared tube in the present embodiment includes transmitting terminal and receiving terminal, and transmitting terminal emits infrared
Line is received in the case where not being blocked by receiving terminal, and receiving terminal feeds back to one high ordinary mail number of microcontroller；Infrared ray is blocked
When, receiving terminal feeds back to one LOW signal of microcontroller.There are a series of spacing 45mm at 8 edge of filter membrane, and size 5mmx5mm's is small
8 edge of filter membrane is placed among the U-type groove of infrared tube by hole, and aperture faces the transmitting terminal and receiving terminal of infrared tube.It is to be filtered
Film 8 is stain to aperture when needing replacing, is detected to pipe, starts motor 11, and active roller bearing 10 rotates, and replaces filter membrane 8, until inspection
The appearance of next aperture is surveyed, stops motor 11.Ensure that the length for updating filter membrane section every time is consistent with this, improve making for filter membrane 8
With rate.
The filter membrane 8 can also be filter paper；The upper and lower cover plates material is plastics or metal.
Embodiment 2：Under lab, this filter is used continuously to filter water sample of the original turbidity for 148NTU, will be discharged
Pipe 15 is connect with the sample feeding pipe of online turbidimetry, and the turbidity of the rear water sample of acquisition is as shown in Figure 2.Turbidity maintain 1NTU with
Under level, illustrate that filter effect is excellent.
Embodiment 3：Filter in embodiment 1 and nitrous blood urea/nitrogen analyzer are combined, in Xiamen University of Fujian Province Xiang peace school
Water sample turbidity after nitrous nitrogen concentration and filtering in the METHOD FOR CONTINUOUS DETERMINATION water sample of area lotus lake.Water after filter sample flows into one by outlet pipe
5mL test tubes are ensured the real-time update of water sample in the form of overflow and bubble are avoided to enter analyzer.Nitrous blood urea/nitrogen analyzer into
Water pipe is also inserted into test tube, and the water sample after filtering continuously enters Instrument measuring absorbance, is converted through nitrite nitrogen standard working curve
Obtain the concentration that nitrite nitrogen changes over time in water sample, water sample turbidity after turbidity standard working curve converts to filter.It behaves in this lake
Work lake is the system of a closing, and the water flows gently, and mobility is low, is nowhere polluted, and therefore, nutrient concentration is relatively low, changes model
It encloses smaller.The turbidity of live METHOD FOR CONTINUOUS DETERMINATION water after filter sample is in 1NTU hereinafter, in-line analyzer can be directly entered.
Embodiment 4：This filter is carried out row boating type application by the present embodiment in Fujian Province's Jiulongjiang Estuarine, to filter
Filter effect carry out on-site verification.Device and step are as described in embodiment 1 and 3, on-line continuous analysis water after filter sample turbidity.
In addition, acquiring raw water sample every 30min, determined off-line original turbidity of sea water behind laboratory is taken back.Former turbidity of sea water and scene are online
The Comparative result of turbidity of sea water is shown in Fig. 4 after the filter of measure, after live METHOD FOR CONTINUOUS DETERMINATION filtering the turbidity of seawater in 1NTU hereinafter, table
Bright automatic filter has good filter effect to the water sample of different turbidity, available for turbidity variation range is big, live ring
The on-line continuous automatic fitration of the more severe practical water body in border.
Embodiment 5：The present embodiment navigates to effect associated with filter and nitrous blood urea/nitrogen analyzer into walking in Jiulongjiang Estuarine
Formula application verification.When walking aerial survey fixed period during high tide.Device and step are continuous to survey as described in embodiment 1 and 3
Determine the nitrous nitrogen concentration in water, while every 10min with YSI Instrument measuring water salinities.The variation of salinity and nitrous nitrogen concentration
Trend is shown in Fig. 5.As shown in Figure 5, the concentration of nitrite nitrogen is inversely proportional with salinity height in the surface seawater of observation area, meets objective rule
Rule.In Jiulongjiang Estuarine, at ebb tide due to the input of river, salinity decrease, nitrous nitrogen concentration is higher；Open seawater is defeated at the incoming tide
Enter, salinity increases, and the relatively low open seawater of nitrous nitrogen content dilutes the higher river water mouth of content, in water body nitrite nitrogen content with
Decline.The regularity of distribution of nitrite nitrogen and salinity and Lin Kunning et al. in the Jiulongjiang Estuarine that this research obtains[5]Contemporaneity exists
The observed result of Jiulongjiang Estuarine is consistent.Walk boat application the result shows that, the set combination equipment can apply to water body on-line filtration and
The on-line checking of nutritive salt such as nitrite nitrogen.
The above, only the utility model preferred embodiment, therefore the utility model implementation cannot be limited according to this
It is new all should still to belong to this practicality for range, i.e., the equivalent changes and modifications made according to the utility model patent range and description
In the range of type covers.
