Abstract

This invention relates to the field of water quality testing technology and provides a water quality testing and analysis system, including a sample pretreatment unit, a digestion reaction unit, an integrated detection unit, and a data processing and control unit. The data processing and control unit is electrically connected to the sample pretreatment unit, the digestion reaction unit, and the integrated detection unit, respectively. The outlet of the sample pretreatment unit is connected to the inlet of the digestion reaction unit and the inlet of the integrated detection unit, respectively, to achieve parallel processing of water samples. The integrated detection unit includes a first detection module and a second detection module. Through the dual-path split design of the sample pretreatment unit, parallel and synchronous processing of total emission detection and qualitative and quantitative analysis of organic pollutants is achieved, reducing repetitive operations in sample pretreatment. At the same time, this invention adopts a stepwise dissolution-cooling mixing process for both total nitrogen oxidant and total phosphorus colorimetric catalyst, which reduces the damage of heat of dissolution to active components from a physical perspective.
