Recently, in the laboratory of the Municipal Drainage Company, a special "Technology Guardian" has been carrying out its work in an orderly manner: flexibly lifting, rotating, and extending its robotic arm to accurately collect water samples, automatically identifying key data through built-in sensors, and analyzing water quality parameters in real time.
This "Technology Guardian" is the city's first national standard-compliant intelligent water quality analysis device recently deployed by the Municipal Drainage Co., Ltd. It can rapidly test various water quality indicators simultaneously in accordance with the national standard method. It is reported that the project has a total investment of 1.95 million yuan, covering the installation and subsequent operation and maintenance of equipment such as automated water quality testing devices, activated sludge settling instruments, and biological phase microscopes, etc. Currently, it is in the debugging phase and will soon officially "begin its duties".
Water quality monitoring and analysis is a complex process, with each step requiring the "handling" of professionals. However, the "Technology Guardian" can easily handle the entire workflow—from sample identification and precise sampling to reagent addition, heating digestion, detection analysis, and data transmission—all automatically.
The reporters learned that, unlike the tedious "bottle-shaking and droplet-dripping" process of manual testing, the device can quickly identify sample information through multi-module scanning technology, with its robotic arm performing sampling and liquid dispensing with millimeter-level precision. It integrates colorimetric analysis and electrochemical sensing technology, simultaneously using the national standard method to test four core water quality indicators of chemical oxygen demand, total phosphorus, total nitrogen, and ammonia nitrogen. The entire process requires no manual intervention and can automatically generate complete test reports, achieving dual improvements in both efficiency and accuracy.
Under the traditional manual testing mode, analyzing the four core indicators of a batch of sewage samples using the national standard method requires several laboratory technicians working together for several hours. Now, with the "Technology Guardian," up to 10 water samples can be tested in a single run, all using the national standard method rather than online rapid testing methods. The device can operate continuously 24/7, significantly improving testing efficiency.
"The device adopts a relatively enclosed operational process, isolating harmful reagents from sampling to analysis, significantly reducing the occupational health risks for laboratory personnel and shifting laboratory safety protection from 'passive response' to 'active prevention and control'," introduced a relevant person in charge from the Municipal Drainage Co., Ltd.
It is reported that since the beginning of this year, the Municipal Drainage Company has continued to promote intelligent upgrades, installing new intelligent water samplers at key points such as sewage outlets. This equipment can automatically perform timed sewage sampling 24/7 without interruption, providing more accurate original data for water quality analysis. Currently, the equipment debugging is in its final stages, and the company is simultaneously completing the acceptance of activated sludge settling instruments and biological phase microscopes to ensure the equipment is compliant and ready for use.
