Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] Please refer to the attached figure 1 , which is a flowchart of an embodiment of a liquid quantitative sampling method disclosed in the present invention, the method may include:

[0026] Step S101: Obtain adjustment parameters.

[0027] In practical applications, because a variety of liquids are sampled, and the degree of pollution and solid particle impurities contained in each liquid may be different, the amount of sampling required for different li...

Abstract

The embodiment of the invention discloses an online water quality monitoring method and instrument. The method comprises the following steps of: obtaining adjusting parameters; determining the depth of a suction tube inserted into a container according to the adjusting parameters, wherein the depth refers to the distance from the surface of a water body to be detected in the container to the port of the suction tube; extracting the water body to be detected, which is indicated by the depth, through the suction tube; and detecting the extracted water body to be detected. By utilizing the online water quality monitoring method and instrument disclosed by the embodiment of the invention, the water level of the container is descended when the water body in the container is extracted by the suction tube; when the water level is descended to the port of the suction tube, the suction tube cannot extract the liquid in the container, i.e., the aim of quantitatively sampling through utilizing a simple step of adjusting the depth of the suction tube in the container can be achieved, so that the quantitative sampling is more accurate. Furthermore, the water quality detection is more accurate.

Description

technical field [0001] The invention relates to the field of liquid detection, and more specifically relates to a water quality on-line monitoring method and an on-line monitor. Background technique [0002] With the development of industrial automation and the improvement of people's living standards, a large amount of industrial wastewater and liquid sewage are discharged into water bodies such as rivers, lakes and oceans, so the detection of pollutant components in liquid is imperative. [0003] The liquid detection technology includes a sampling step. The existing liquid detection sampling technology is a method of controlling the liquid level in the container, that is, the liquid is sampled into a container, and the height of the liquid level is controlled by a sensor to achieve the purpose of quantitative sampling. When the specified liquid level is reached, the flow rate of the inflow liquid should be reduced to gradually reach the specified liquid level. In this pro...
