Method and device used for detecting water body transparency

Abstract

The invention discloses a method and a device which are used for detecting water body transparency. According to the method, penetration of water boy by light sources is realized at three different positions of a water area to be detected, the light power at the three positions is detected, and water body transparency L is determined based on formula 1. The device comprises a sealed chamber, a data acquisition module, a data analysis module, a control module, and a power supply. Compared with the prior art, the method possesses following advantages: light intensity difference collected by a light intensity receiver is taken as the transparent degree L of the water body, the automatic degree is higher than that of transparent scale method, error caused by artificial measuring is avoided. Inthe method, differential method is adopted to measure water body transparency for the first time, and generation of external interference and accumulated error is eliminated from principles; the suitable range is wide; the device can be used at water areas impossible for artificial measuring such as high density and automatic collection at water towers or in the wild; measuring cost is reduced greatly; a large amount of data sample is obtained; and real-time detection is realized.

Description

technical field

[0001] The invention relates to the technical field of water body transparency detection, in particular to a water body transparency detection method and a water body transparency detection device. Background technique

[0002] As an important parameter to describe the visibility of water body optical properties, water transparency is an important index to measure the quality of water, evaluate the eutrophication of lakes and water pollution prevention and control, and it is also indispensable in the investigation of water quality of reservoirs, lakes and surface water. project. With the increasingly serious problem of water pollution, the monitoring of water transparency has become a major issue that must be solved for the sustainable development of society and economy. The water quality of lake water is closely related to national production and people's life. Therefore, fast and accurate monitoring of lake water transparency is particularly important. ...
