Abstract

The invention provides a miniature multifunctional water quality analysis device. The device comprises a shell and a flow cell arranged in the shell, a light hole, a reference hole and a detection hole are formed in the shell, the light hole is rotationally connected with an LED lamp set, the reference hole is rotationally connected with a reference diode set, the detection hole is rotationally connected with a detection diode set, and a sample inlet and a sample outlet are further formed in the shell; the light transmitting hole, a light path channel of the flow cell and the detection hole are coaxially arranged, a sample inlet pipe connected with the sample inlet is arranged at the lower end of the flow cell, a sample outlet pipe connected with the sample outlet is arranged at the upper end of the flow cell, a temperature sensor is arranged in the flow cell, a resistance wire is arranged on the outer surface of the flow cell, and an ultraviolet lamp is sleeved outside the flow cell. And the ultraviolet lamp can do reciprocating rectilinear motion along the light path direction of the flow cell. The device integrates various analysis functions of high-temperature digestion, ultraviolet reduction, optical detection and the like, and is compact in structure, small in size, small in reagent consumption, high in analysis speed and convenient to use, and miniaturization is realized.

Description

technical field [0001] The invention relates to the technical field of water quality monitoring, in particular to a miniature multifunctional water quality analysis device. Background technique [0002] Wet chemical system online monitoring equipment is the main means of obtaining freshwater and seawater ecological environment data on site. It can monitor and measure the types of nutrients and pollutants in water, the concentration and change trend of various nutrients and pollutants, and evaluate the health level of water. It can provide technical support and decision-making basis for water quality environmental pollution monitoring and prevention. At the same time, it can also provide services for aquatic resource conservation and fishery activities, and realize early warning and forecasting of natural disasters such as algal blooms. [0003] However, the detection of wet chemical parameters is still mostly performed by laboratory manual methods. On the one hand, since t...
