Embodiment
1. the acquisition and analysis of sample
All valves are first shut off, filter 5 is placed in the underwater among river, opens water pump 3, flushing line 4 and water Pump 3, then turns on valve I 6, and 3 are switched off the pump when 10 liquid level of liquid storage bottle is more than body 2/3, records the reading of electronic balance 9;
Swivel tee piston 14 makes filter 12 be connected to peristaltic pump 15, and then adjusting valve 16 makes peristaltic pump 15 and exhausted bath box 8 Connection, opens the water flushing line that peristaltic pump 15 extracts liquid storage bottle 10, and then adjusting valve II 16 makes peristaltic pump 15 and conductance cell Measuring system pipeline is rinsed in 18 connections;Washing time, the higher washing time of water transparency are determined according to the muddy degree of water body It is longer, then record pH, conductivity and temperature in multiparameter water quality analyzer 20;
Adjusting valve II 16 again makes peristaltic pump 15 be connected to sampling bottle 17, collects water sample;
Water sample first adjusts valve II 16 peristaltic pump 15 is made to be connected to conductance cell 19 after collecting, then adjusts stop,threeway 14 and make deionization Water holding bottle 13 is connected to peristaltic pump 16, and peristaltic pump 16 extracts deionized water flushing line, when multiparameter water quality analyzer 20 Conductance reading stops flushing line when constant, reads again the reading of electronic balance 9, removes the filter membrane in filter 12, cleans Filter 12 loads onto new filter membrane.
The calibration of 2.pH meters 23
It is pH meter calibration liquid respectively in correcting fluid bottle I 25, correcting fluid bottle II 26 and correcting fluid bottle III 27, adjusts stop,threeway first 14 and valve II 16 so that deionized water holding bottle 13 is connected to peristaltic pump 15.Peristaltic pump 15 is connected to conductance cell 18, is opened and is wriggled 15 flushing lines are pumped, when the electric conductivity value that multiparameter water quality analyzer 20 is shown is constant, pH is 7, close peristaltic pump 15;Then it beats Valve opening door III 28 makes calibration liquid in correcting fluid bottle I 25 enter pH measuring appliances 22, demarcates pH meter 23, valve III is closed after the completion of calibration 28, it then turns on peristaltic pump 15 and rinses pH measuring appliances 22, pH meter 23 is demarcated followed in turn by other calibration liquid.
3. the calculating of insoluble microparticle concentration in water sample:
By electronic balance 9, the decrement of water sample in liquid storage bottle 10 can be calculated, by filter membrane in weighing filter 12 in mistake With filtered dry sample before filter, the weight of insoluble microparticle in filtered water body can be obtained.Insoluble microparticle weight divided by storage The decrement of water sample in liquid bottle 10, so that it may to obtain insoluble microparticle concentration in water sample.
