Specifically, in the present embodiment,
(1) by field acquisition to water body example be placed in water sample collection device 80, bottle is specially preserved, by above-mentioned implementation De- 100 assembly and connection of solution collection device of solution gas is good in water body in example, connects each component power.(2) it when initial, needs pair Gas-liquid separation storehouse 10 is vacuumized;When baroceptor 50 detects that gas-liquid separation storehouse 10 is normal pressure, control system opens electricity Magnet valve 40, and start vacuum pump 30 and start to vacuumize gas-liquid separation storehouse 10, when air pressure reaches in gas-liquid separation storehouse 10 When to the first predetermined vacuum degree P1, vacuum pump 30, which stops being evacuated, simultaneously closes solenoid valve 40.(3) it is arranged and starts the pump housing, has Body is flow-rate adjustment pump, and sample water body enters hollow fiber conduit 11 by liquid line with certain flow velocity at this time;(4) work as water body When sample flows in hollow fiber conduit 11, since hollow fiber conduit 11 is in the gas-liquid separation storehouse 10 in negative pressure state, Between gas-liquid two-phase under the action of partial pressure gradient, using the characteristic of 11 film hydrophobic, air-permeability of hollow fiber conduit, the methane etc. that is dissolved in water Gas, which will be slow, to be discharged into the warehouse 12 of gas-liquid separation, increases 12 air pressure of warehouse slowly.When baroceptor 50 detects When 12 air pressure of warehouse is increased to the second predetermined vacuum degree P2, electromagnetic valve of gas circuit 40 is opened, the starting of vacuum pump 30 is evacuated, at this time Sample gas is entered in gas collector 70 by the exhaust outlet of vacuum pump 30;When baroceptor 50 detects gas-liquid point When being again lowered to preset value P1 from air pressure in storehouse 10, stops being evacuated and close solenoid valve 40.Therefore, in gas-liquid separation storehouse 10 Air pressure maintains between P1~P2 always, and the sucking rate of each vacuum outgas pump is also definite value.(5) sample water after degassing Body flows into waste liquid pool 90 by the liquid outlet 14 in gas-liquid separation storehouse 10.(6) it repeats above operation, until whole samples water body is de- Gas is completed.(7) the sample tolerance and water body amount of statistical collection, the sample gas of collection is with rubber stopper and a small amount of saturated salt solution Gas bottle be sealed, be used for further gas chromatographic analysis test and concentration calculation.
Under tentative standard state, it is V (mL) that solution is taken off from W (mL) sample water to obtain the volume of solution gas, and degassing efficiency is μ obtains CH in gas through gas chromatographic analysis4Concentration is c (ppm), then dissolves CH in raw sample water4Concentration ω (nmol/L) Calculation formula are as follows:
Since gas-liquid separation is the slowly varying process of an air pressure, the gas flow only isolated in gas-liquid separation storehouse 10 It reaches a certain level, reduces the intracavitary vacuum degree of gas-liquid separation box, control system just starts degassing pump work and extracts sample gas. So theoretically, the length of hollow fiber conduit 11 is longer, flow rate of liquid is slower, the vacuum degree in gas-liquid separation storehouse 10 is higher, even Continuous degassing and collection gas flow are bigger, better to the degasifying effect of environment water, and it is also closer to analyze the dissolution gas concentration measured True value.Therefore hollow fiber conduit 11 is arranged in the shape of a spiral in the warehouse 12 in the present embodiment.By by hollow fiber conduit The setting of 11 spirals, increases the length of the winding in warehouse 12 of hollow fiber conduit 11.
It will be apparent to those skilled in the art that can make various other according to the above description of the technical scheme and ideas Corresponding change and deformation, and all these changes and deformation all should belong to the protection of the utility model claims Within the scope of.
