During the production process, sometimes equipment may detect fluctuations or rapid increases in data, and manual analysis is obviously too slow. So with quick detection test strips and reagent kits, it is possible to quickly strengthen the judgment, although the specific values are not known, at least the general direction will not be wrong. Of course, we can also use it when inspecting the pipeline network. 1、 PH test paper
PH value is a key indicator reflecting the acidity and alkalinity of wastewater. The accuracy of common pH test strips is usually between 0.5-1 pH unit. When in use, immerse the test strip fully in the water sample to be tested, let it sit for a while, and then take it out. Compare it with the standard color chart to quickly determine the pH value of the water sample, which is generally between 1-14. The pH of the influent in sewage treatment plants should usually be controlled between 6-9, and the pH of the effluent should also be stable within this range to meet discharge standards. 2、 Residual chlorine test paper
Used for rapid determination of residual chlorine content in water. The residual chlorine level is directly related to the disinfection effect. The detection range of common residual chlorine test strips is between 0.05-10 mg/L. In the disinfection process of sewage treatment plants, the residual chlorine content in the effluent generally needs to be maintained at 0.1-0.5 mg/L to ensure effective disinfection and prevent the discharge of pathogenic microorganisms. 3、 Ammonia nitrogen reagent kit
Ammonia nitrogen is one of the important parameters for evaluating sewage quality. The reagent kit is based on the principle of colorimetric reaction and can detect ammonia nitrogen concentration in a short period of time. The common detection range is 0.1-50 mg/L. According to different regions and emission standards, the ammonia nitrogen concentration in the effluent of sewage treatment plants is usually required to be lower than 1.5-5 mg/L. 4、 Chemical Oxygen Demand (COD) reagent kit
COD can reflect the total amount of organic matter in water. The rapid COD reagent kit can usually provide results within 15-30 minutes, with a detection range of approximately 10-1500 mg/L. The COD discharge standard for effluent from sewage treatment plants is generally below 50 mg/L. 5、 Total phosphorus reagent kit
The detection of total phosphorus is of great significance in determining the risk of eutrophication in water bodies. The reagent kit is developed by chemical reaction, and the detection range is usually between 0.01-5 mg/L. The total phosphorus concentration in the effluent of sewage treatment plants is generally required to be below 0.5 mg/L. 6、 Nitrate Nitrogen Reagent Kit
Used to determine the content of nitrate nitrogen in water. The detection range is generally between 0.1-50 mg/L. In sewage treatment, the content of nitrate nitrogen should be controlled within a reasonable range to avoid adverse effects on the environment. 7、 Nitrite nitrogen reagent kit
It can quickly detect the concentration of nitrite nitrogen in water samples, with a detection range of 0.01-1 mg/L. Its content is also one of the important indicators for evaluating water quality. 8 Dissolved oxygen (DO) detection uses a portable dissolved oxygen meter, immersing the probe into the sewage sample and directly reading the DO value.
Data interpretation: During aerobic biological treatment, the DO value should generally be maintained at 2-4 mg/L. A low DO value may lead to a decrease in microbial activity, while a high value may indicate excessive aeration, resulting in energy waste. When using these rapid testing strips or reagent kits, it is essential to strictly follow the operating instructions to ensure the suitability of the testing environment and the standardization of the operation. At the same time, it is important to ensure that the storage environment does not become ineffective. As for where these things can be purchased, online shopping is a good thing.
