Description

Portable water quality sampling instrument

Technical Field

The utility model relates to a water sampling field especially relates to portable water sampling appearance.

Background

Collecting a water sample of the polluted water body, and analyzing and determining to obtain basic data of water body pollution. The water sample for analysis should be representative and can reflect the chemical composition and characteristics of the water body. The sampling method, position, time, frequency and the like are determined according to the characteristics of the water body and the analysis purpose. A water sample for analyzing the chemical components of natural water of a river is generally collected 0.2-0.5 m below the surface of a hong body in a flow measuring section of a hydrological station, and a sampling point is added when the section is wide. The shoreside sampling point is required to be arranged at the position where water flow is smooth. Samples can also be taken in layers at different depths if desired. The sampling times are uniformly distributed in different periods and different flow rates according to the water regime change. The test should be carried out in the full water period, the normal water period and the dry water period. The flood runoff accounts for rivers with high annual runoff proportion, and sampling in the flood period should be increased. And the small flood peak takes a water sample at the peak top, and the large flood peak takes a water sample of rising water, the peak top and falling water. When the field investigation of river water quality is carried out, sampling is carried out at the main stream position of a straight river channel. Otherwise, the sampling is carried out at a place with a large flow rate by keeping the distance from the shore as far as possible. A water sample for analyzing chemical components of sewage is collected by the above method. When researching the water pollution law and the characteristics thereof, a sampling section is additionally arranged, and a contrast section, a pollution section and a purification section are respectively arranged at the upstream and the downstream of a riverway near important pollution sources (a large city, an industrial area and the like) and at the downstream far away from the pollution sources, so as to know the water quality conditions of an uncontaminated river reach and a polluted river reach and the water quality purification trend. The polluted cross section of the large river is provided with three sampling vertical lines of a left bank, a river center and a right bank; the reference section, the purification section and the pollution section of the small river can be only provided with a center vertical line. A surface water sample is generally collected by each vertical line; the vertical line of the river center can also be sampled in layers or in a mixed manner.

The existing water quality sampling equipment is simple in structure and poor in sampling effect, and more domestic garbage or aquatic organisms enter the device during sampling, so that the device is extremely easy to be interfered by adverse factors, and the acquisition of water samples is influenced and needs to be improved.
