Description
Technical Field
The invention relates to the technical field of water quality analysis, in particular to a water quality detection and analysis system for sewage treatment.
Background
Water quality testing is a process of assessing various physical, chemical and biological properties in a body of water, with the aim of determining the applicability, safety and pollution level of the water. Water quality detection is an important measure for protecting public health and environment, and is widely applied to the fields of drinking water, underground water, surface water, rivers, lakes, oceans and sewage.
The water quality detection and analysis system for sewage treatment is an advanced technical solution for realizing real-time, continuous and automatic monitoring of water quality in the sewage treatment process. The system collects water quality parameter data in the sewage treatment process in real time through a sensor network arranged in a sewage treatment facility, wherein the water quality parameter data comprise pH value, dissolved oxygen concentration, suspended solid concentration, COD, BOD, ammonia nitrogen and total phosphorus.
Through the collected data, the system can perform water quality analysis and evaluation to help sewage treatment plants monitor and control water quality conditions. The system can analyze trends and anomalies in water quality data, discover potential water quality problems in advance, and support decision makers to take corresponding measures. In addition, the system can generate a water quality detection report, including sample information, analysis results and evaluation conclusions, and provides scientific basis for decision makers.
However, in practical use, there are still some drawbacks, such as, first, that the data collected in the prior art when evaluating the water quality level of a water body tend to be biased to a few water quality indicators, such as pH, dissolved oxygen, ammonia nitrogen. This single-index data collection method limits the overall assessment of water quality. To improve the comprehensiveness of the assessment, it is necessary to consider the collection of more water quality metrics, including physical, chemical and biological parameters such as total suspended matter, total phosphorus, biochemical oxygen demand, heavy metal content and algae metrics. Secondly, the prior art often ignores the influence of the environmental conditions of the water body and different depths on the index in the process of collecting the water quality index. Environmental conditions of the water body, such as water flow speed, temperature and characteristics of different depths of the water body, can influence the distribution and change of water quality indexes. Therefore, in the data acquisition process, the environmental factors are considered, and the data are acquired at different depths or sampling points, so that the overall water quality condition of the water body can be accurately known.
