Description

Technical Field

[0001] This utility model relates to the technical field of wastewater testing devices, specifically to a wastewater testing test chamber. Background Technology

[0002] Industrial wastewater contains various pollutants such as COD, ammonia nitrogen, and heavy metals (e.g., chromium, copper, lead). The detection of different pollutants relies on specific chemical reaction principles. For example, COD detection requires the potassium dichromate oxidation method, ammonia nitrogen detection requires Nessler's reagent, and heavy metal detection requires a composite system of chelating agents and colorimetric reagents. According to the Ministry of Ecology and Environment's "Technical Guidelines for Self-Monitoring by Pollutant Discharge Units," enterprises are required to regularly conduct on-site testing of multiple indicators and record the data. This places higher demands on the reagent compatibility and ease of operation of testing equipment. Furthermore, rapid on-site detection of sudden pollution incidents, such as pipeline leaks or illegal discharges, often requires simultaneous qualitative and quantitative analysis of multiple indicators.

[0003] Traditional laboratory testing methods, due to their bulky equipment, cannot meet the needs of real-time testing under complex conditions. Existing portable wastewater testing equipment mostly adopts a design that separates the testing unit from consumables, requiring on-site assembly of test tubes, colorimetric cards, and other components during operation. This not only poses risks of component loss and reagent exposure but also makes it easy for reagents for different testing indicators to be confused. Therefore, this application proposes a wastewater testing chamber. Utility Model Content

[0004] To overcome the problems in the background technology, this utility model provides a wastewater testing chamber, which solves the problems that traditional laboratory testing methods cannot meet the needs of real-time testing due to the large size of the equipment, and that existing portable wastewater testing equipment has the problem of the separation of the testing body and consumables, resulting in the risk of component loss, exposure, and reagent confusion.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A wastewater testing chamber includes a chamber body, a lid, and test tubes. The chamber body is provided with an experimental tank and a testing tank. Limiting plates are provided in the experimental tank and the testing tank. The wall panel of the testing tank is a transparent wall panel with a colorimetric card slot. The test tubes are placed in the chamber body through the limiting plates. The lid and the chamber body are detachable.

[0007] Furthermore, the test tube includes a tube shell, a pipette, a sealing sleeve, and a reagent reservoir. The reagent reservoir is installed on the top of the sealing sleeve, the pipette is installed on the bottom of the sealing sleeve and connected to the reagent reservoir, the sealing sleeve is threaded to the top of the tube shell, and a sealing block is provided at the bottom of the tube shell to abut against the bottom end of the pipette.

[0008] Furthermore, a sample injection area is provided at the top of the sealing sleeve.

[0009] Furthermore, the box cover is provided with a fixing plate that abuts against the injection area of ​​the sealing sleeve.

[0010] Furthermore, a tool compartment is provided at the bottom of the box.

[0011] The beneficial effects of this utility model are:

[0012] This application integrates detection, storage, and protection functions through a unified cabinet structure. Test tubes pre-package reagents within the tubes to avoid confusion and reduce operational steps. Transparent detection slots and colorimetric card slots enable rapid readings. The cabinet is clearly divided into sections, and tools and consumables are centrally stored, making it suitable for on-site testing. This solves the problems of traditional laboratory testing methods being too bulky to meet immediate testing needs, and existing portable wastewater testing equipment having separate testing components and consumables, leading to risks of component loss, exposure, and reagent confusion.
