Embodiment 1

[0039] A kind of multi-parameter water quality on-line monitoring integrated system of this embodiment, such as figure 1 As shown, it includes an external unit 1, which is a double-layer thermal insulation structure. A chemical reaction box 11, a reagent box 12, and an electrode box 13 are arranged in sequence from the bottom, and a pump valve integrated module 2, a multi-way valve integrated module 4 and a digestion integrated module 5 are installed in the chemical reaction box 11, and the multi-way valve The integrated module 4 is communicated with the integrated digestion module 5 through the injection tube 51; the pump valve integrated module 2 is communicated with the multi-way valve integrated module 4 through the reagent quantitative loop 3, and the reagent quantitative loop 3 is a ring structure, including The liquid port 31 and the liquid outlet 32, the internal capacity of the ring structure of the reagent quantitative loop 3 is 5mL, so as to accurately control the c...

Embodiment 2

[0042] A kind of multi-parameter water quality on-line monitoring integrated system of this embodiment, the basic structure is the same as embodiment 1, and the differences and improvements are as follows: figure 2 As shown, the multi-way valve integrated module 4 is a double-row multi-pipeline structure, on which air pipes 40, acid solution pipes 41, alkaline solution pipes 42, oxidant pipes 43, reducing agent pipes 44, and sampling water pipes are respectively installed. 47. Each pipeline is controlled by its own solenoid valve. By controlling the solenoid valves on each pipeline, acidic solution, alkaline solution, oxidant tube, reducing agent tube, and sample water are sequentially drawn from the reagent box 12 into the reagent quantitative loop. 3, then extract air through the air pipe 40 to discharge the liquid in each tube through the injection pipe 51 into the integrated digestion module 5 for mixing, so as to play the role of pumping and stirring;

[0043] In this em...

Embodiment 3

[0045] A kind of multi-parameter water quality on-line monitoring integrated system of this embodiment, the basic structure is the same as embodiment 2, and the differences and improvements are as follows: figure 2 As shown, the digestion integrated module 5 includes a digestion pipe 53, an upper high pressure valve 52 is provided at the upper end of the digestion pipe 53, a lower high pressure valve 54 is provided at the lower end of the digestion pipe 53, and a resistance wire is provided inside the digestion pipe 53. , a temperature sensor and a thermal fuse, so that the mixed liquid in the digestion tube 53 is heated, pressurized and kept under pressure to realize the digestion reaction, and the thermal fuse can play a protective role in the case of a temperature sensor failure; The lower high-pressure valve 54 is connected with an injection pipe 51, and the end of the injection pipe 51 away from the lower high-pressure valve 54 is connected to the multi-way valve integrat...

Abstract

The invention discloses a multi-parameter water quality online monitoring integrated system and a monitoring method thereof, and belongs to the technical field of water quality online monitoring. According to the multi-parameter water quality online monitoring integrated system and the monitoring method thereof, the multi-parameter water quality online monitoring integrated system comprises an outdoor unit, and an outdoor unit air-conditioner is installed outside the outdoor unit so as to keep the constant-temperature and constant-humidity environment inside the outdoor unit; the outdoor unitsequentially comprises a chemical reaction box, a reagent box and an electrode box from top to bottom, and a multi-way valve integration module is arranged in the chemical reaction box and is communicated with a pump valve integration module through a reagent quantifying ring, so that the detection efficiency and precision are improved; the multi-way valve integration module respectively forms integrated flow path channels, the channels are respectively introduced into various detection reagents in the reagent box, and various parameters in online monitoring water quality are measured througha chemical colorimetric method, so that the integration degree is higher, and intelligent automatic measurement can be realized.

Description

technical field [0001] The invention relates to the technical field of online water quality monitoring, and more specifically relates to a multi-parameter water quality online monitoring integrated system and a monitoring method thereof. Background technique [0002] At present, in response to serious problems such as the deterioration of the water environment and the degradation of river and lake functions, online monitoring of river water quality has been put on the agenda. Unlike the traditional online monitoring of water quality of pollution sources, which only measures a single parameter, online monitoring of river water quality requires monitoring There are generally more than nine parameters, and the monitoring indicators cover: five parameters of water quality (temperature, pH, dissolved oxygen, conductivity, turbidity), permanganate index, chemical oxygen demand (COD), ammonia nitrogen, total phosphorus, total Nitrogen, heavy metals, flow and other monitoring indica...
