Detection device and water quality online detection system with the detection device

Abstract

The invention discloses a detection device and an online water quality detection system provided with the detection device. The detection device comprises a detection tank which is provided with a reagent inlet, a water sample inlet, an air inlet, an overflow hole and a liquid discharge hole, wherein the detection tank is also provided with a mixing hole; the mixing hole is connected with a mixing pump used for mixing the mixed liquid in the detection tank; the mixing pump is connected with a controller used for controlling the work of the mixing pump; the detection tank is also provided with a heating device and a temperature sensor used for detecting the temperature of the wall body of the detection tank; the controller is used for receiving signals of the temperature sensor and controlling the work of the heating device. According to the detection device, the design with multiple functions of reaction, heating, temperature control, mixing, detection, overflowing and the like can be realized, the space occupation area is reduced, installation parts are saved, and the consumption of a water sample and a reagent can be greatly reduced; furthermore, long optical path design is adopted, so that the detection sensitivity is high.

Description

technical field [0001] The invention relates to the field of online detection of water quality, in particular to a detection device. In addition, the present invention also relates to an online water quality detection system comprising the above detection device. Background technique [0002] At present, the working process of the online water quality analysis instrument is to first inject the water sample to be tested into the detection pool, and then through the control system, the reagents are sequentially injected into the detection pool quantitatively, a chemical reaction occurs, and the chromogenic solution after the reaction passes through the optical detection system. Measurement is carried out in order to measure various parameters of the tested water sample. The current online water quality analyzers use negative pressure devices to transport water samples and reagents to the detection pool. At present, the most widely used negative pressure devices include perist...
