Embodiment 1

[0058] Such as figure 1 As shown, a water quality monitor includes a casing 1 in which a sampling device 6, a reaction device 7, a detection device 8 for detecting the absorbance of a sample and a control terminal are arranged in the casing 1. There is a mounting plate 2 on which the sampling device 6 , the reaction device 7 and the detection device 8 are all installed. A display screen 3 is arranged on the outer wall of the casing 1, and the display screen 3 is electrically connected to the control terminal. A reagent placement platform 4 is arranged below the sampling device 6 in the casing 1, and several cylindrical placement grooves 5 are provided on the placement platform 4, and the reaction reagents are placed in the placement grooves 5 during use. A refrigeration device 28 for storing chemical reagents is arranged in the casing 1 , and the refrigeration device 28 is located below the placement table 4 and is fixed with the casing 1 by bolts.

Embodiment 2

[0085] The difference with Embodiment 1 is that, if figure 1 , Figure 5 As shown, a water quality on-line monitor also includes two solenoid valves 33, the two solenoid valves 33 are respectively located at the two ends of the installation shell 71 and are communicated with the reaction bottle 72 through a conduit, and the solenoid valve 33 plays a sealing role to prevent the During the heating process of the bottle 72, steam escaped, causing the pressure of the reactor to change after returning to normal temperature, which affected the measurement results.

[0086] Because there are corrosive reagents in the reagents for detecting the content of total phosphorus, the rotating disc 614, fixed disc 615, valve body seat 611 and valve seat cover 612 of the ten-way valve 61 are all made of corrosion-resistant materials to prolong the service life of the ten-way valve 61 .

[0087] Working process of the present invention is as follows:

Abstract

The invention provides a water quality monitor, and relates to the technical field of water quality monitoring equipment. The water quality monitor comprises a shell; a sample introduction device, a reaction device, a detection device and a control terminal are arranged in the shell; the sample introduction device comprises a ten-way valve, a metering bottle and a peristaltic pump; a main branch of the ten-way valve communicates with the metering pump through a conduit; the peristaltic pump communicates with the metering bottle through a conduit; the reaction device comprises a reaction bottle; a heating wire is wound on the peripheral side of the reaction bottle; a temperature sensor is arranged in the reaction bottle; and the detection device comprises a light source emitter and a primary light sensor. The water quality monitor has the advantages of high measurement precision, simple operation and reasonable structure.

Description

technical field [0001] The invention relates to the technical field of water quality monitoring equipment, in particular to a water quality monitoring instrument. Background technique [0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in the water body, the concentration and change trend of various pollutants, and evaluating the water quality status. The scope of monitoring is very wide, including unpolluted and polluted natural water (river, river, lake, sea and groundwater) and various industrial drainage. The main monitoring items can be divided into two categories: one is comprehensive indicators reflecting water quality, such as temperature, color, conductivity, BOD, COD, ammonia nitrogen, total phosphorus, total nitrogen, turbidity, PH, dissolved oxygen and other items ; The other is some toxic substances, such as phenol, cyanide, arsenic, lead, chromium, cadmium, mercury and organic pesticides. In order to objectivel...
