Example Embodiment

[0033] Hereinafter, the present invention will be described in detail through exemplary embodiments. However, it should be understood that without further description, the elements, structures, and features in one embodiment can also be beneficially combined into other embodiments.

[0034] In the description of the present invention, it should be noted that the terms "inner", "upper", "lower", "top", "bottom", "one side", etc. indicate the orientation or positional relationship based on the drawings. The positional relationship of is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the pointed device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating ...

Abstract

The invention relates to a water body transparency detection method and a detection device based on the same. The detection method adopts the combination of a camera and a liquid level sensor, wherein the camera is used for recording an image of a water level lowering process in real time so as to obtain a video image from which an identification mark engraved below the bottom of a test barrel can be clearly identified, and the liquid level sensor is used for recording a water level position of a to-be-tested water body in the test barrel in real time, so that the detection efficiency is greatly improved and the operation is convenient; according the obtained video image, result metering is performed by adopting an evaluation model, so that the detection accuracy is improved; and the detection of the transparency of a black and odorous water body can be achieved automatically, the water body is monitored in real time, and the automation degree is high. The detection device provided by the invention highly integrates a sample injection unit and a detection unit, so that an instrument can be miniaturized and can become portable easily, a test can be performed at any time, and the detection device is convenient to use.

Description

technical field [0001] The invention belongs to the technical field of water quality detection, and in particular relates to a water body transparency detection method and a detection device based on the method. Background technique [0002] At present, the state attaches great importance to the regulation of urban black and odorous water bodies. According to the guidelines for the regulation of urban black and odorous water bodies, by 2030, the control target of the overall elimination of black and odorous water bodies in urban built-up areas will be completed. Transparency is one of the indicators for grading and evaluating urban black and odorous water bodies. At present, there are generally two types of indicators for detecting transparency: the black and white plate method and the lead type method. [0003] The black-and-white disk method, namely the Sephardt disk method, is a method for measuring transparency in situ. In this method, the Sephardt disk is submerged in w...
