Description

Multipurpose structure

Technical Field

The utility model relates to a water quality testing field specifically is a multi-purpose structure.

Background

A water quality detector is a chemical analysis instrument for detecting the concentration of different substances in a water body.

Measuring parameters: including total phosphorus, total nitrogen, total mercury, total lead, COD, chlorophyll, turbidity, blue-green algae, pH, and various substances including seawater nutrient salts (such as phosphate, nitrate, nitrite, silicate, ammonium salt, etc.), the measurement parameter range is wide.

The measuring method comprises the following steps: different measuring methods are adopted for different substances, and common measuring methods comprise a spectrophotometer method, a fluorescence method, an electrode method and the like.

Application scenarios: measuring the content of various trace elements in the drinking water; detecting whether the factory discharge of various seriously polluted water bodies reaches the standard or not; the treatment effect of a sewage treatment plant; pollution in fresh water such as rivers, lakes, etc.; distribution and change of various nutrient salt components in seawater, and the like.

The application mode is as follows: according to the closeness degree of the connection between the detected water body and the instrument, the water quality detection instrument can be divided into an off-line type and an on-line type. The off-line type means that the water to be detected needs to be sampled and stored by a third-party tool and then sent into an instrument for detection, the distance between the water to be detected and the detection instrument is long, the timeliness is poor, and the control requirement on chemical reagents is low. The online mode means that the detected water body directly enters an instrument for detection without sampling by a third-party tool, the timeliness is good, but the control requirement on chemical reagents is higher.
