Description
Technical field
The utility model is related to monitoring water environment fields, refer to specifically that a kind of Full-automatic water quality divides sampling device.
Background technology
2002, State Environmental Protection Administration and State Administration for Quality Supervision and Inspection and Quarantine, which combine, to issue《Earth's surface water ring
Border quality standard》(GB 3838-2002), instead of《Environmental Quality Standard of Surface Water》(GB 3838-88) and《Surface water environment
Quality standard》(GBZB 1-1999).?《Water environment quality standard》In (GB 3838-2002), it is desirable that after water sampling
After natural subsidence 30min, the non-settlement section in upper layer is taken to be analyzed by prescriptive procedure.
Specifically divide the statement of sample process substantially similar in different sampling specifications, specially：
(1)《Surface water and sewage monitoring technical specification》(HJ/T 91-2002) 4.2.3.2 section regulations：" (9) are if water sample
In (such as silt) containing settleable solids, then should be separated off.Separation method is：Cylinder glass is poured into after institute's water sampling is shaken up
Container (such as 1~2L graduated cylinders) stands 30min, and the water sample without settleable solids but containing suspended solid is moved into and contains sample appearance
Simultaneously preservative agent is added in device ", " when (10) measure the COD of lake and reservoir water, permanganate index, chlorophyll α, total nitrogen, total phosphorus, water sample is quiet
After setting 30min, water sample is pipetted once or several times with suction pipe, the sharp mouth of suction pipe water inlet should be inserted to the positions water sample surface layer 50mm or less, then
Preservative agent is added to preserve ".
(2)《Monitoring water environment specification》(SL 219-2013) 3.2.8 section regulations：" 1 contains settleable solids (such as silt
Deng) water sample, pour into cylinder glass container (such as graduated cylinder) after institute's water sampling should being shaken up, stand 30min；In water sample surface layer 50mm
Following position adds preservative agent after water sample is moved into sample container with suction pipe；The water sample for measuring total suspended matter and oils removes
Outside ".
Actual sampling, divide sample during, it is possible that following several uncertain factors, to seriously affect detection
As a result so that error occurs in testing result：
(1) from solid (suspended matter) standing sedimentation 30min in dividing sample container can be settled in hydromechanical angle, sample
Process, belong to quiet sedimentation, the rate of settling and suspended matter grain size, composition, content and the Water Environmental Chemistry of Suspended Substance in Water Sample
Etc. features it is closely related, while be also subject to by different types of suspended particle physics, chemistry, biological effect Different Effects its
Flocculation ability causes its rate of settling different.But it to sum up, after sample stands 30min in dividing sample container, suspends in water sample
Object can form a continuous sedimentation band from water meter to container bottom in dividing sample container, and upper layer concentration of suspension is low, more down
Concentration of suspension is higher.Therefore during dividing sample, suction pipe is dense in the sample suspended matter contained therein that different depth pipettes
Degree is inconsistent.And suspension content and the close phase such as permanganate index, COD, metal element content in water sample
It closes.It is this inconsistent, testing result will be made error occur.
(2) what different experiments room may use divides sample drum ladle inconsistent (mainly different vessels diameter is inconsistent),
Point take when same volume sample that (Δ h) is inconsistent for the required depth for pipetting sample；
(3) sample volume that different detection parameters need is different, leads to may have different samples realities during point sample
Border needs point sample volume taken different, i.e., in the case of drum ladle identical (diameter), is moved required for different detection parameters
(Δ h) is inconsistent for the sample depth taken.
(4) different sample managing personnel or sample collector, during point taking sample, because sampling body without strictly control
Product, the sample volume that is pipetted is different and causes point to take inhomogeneities existing for sample room.
(5) because dividing sample process overall process to be manual operation at present, sample is caused to settle the bad stringent control of this time of 30min
System, causes a point sample process to influence testing result.
(6) full manual operation labor intensity is larger, especially notable for this movable weakness of large-scale sample collection.
Therefore providing a kind of Full-automatic water quality divides sampling device to be very necessary.
