Definitions
- the invention relates to the field of environmental monitoring, in particular to a method for monitoring water quality indicators in real time.
- the ultraviolet spectroscopy method for monitoring water quality COD indicators invented in the 1960s has attracted increasing attention, especially the COD measurement technology that uses multiple wavelengths and even the entire ultraviolet-visible spectrum has developed rapidly in recent years.
- This method has the advantage of fast analysis speed, generally only takes ten seconds; and does not require any toxic chemical reagents, such as potassium dichromate, mercury sulfate, silver sulfate, etc., to avoid the environmental risk of secondary pollution.
- This provides a promising alternative method for the widely used COD chemical analysis method, and its economic and environmental benefits are very attractive.
- the COD monitoring technology of UV-visible spectroscopy is to obtain the UV-visible absorption spectrum of the water sample by passing the light beam through the water sample to be measured.
- the COD index of the water sample is obtained by a regression algorithm using the known COD indicators and UV-visible absorption spectrum data of multiple water samples.
- the invention patent with patent number 201710183620.7 uses water sample type identification and remote water sample database to realize the front-to-back interaction of monitoring data through the Internet of Things, which greatly improves the spectral COD measurement method for different water quality types.
- Adaptability Although other indicators of existing water quality, such as permanganate index, nitrate index and turbidity, can be monitored in the same way, multiple water quality index monitors need to be used to detect them separately. This indicator corresponds to a water quality indicator monitor.
- the purpose of the present invention is to overcome the shortcomings of the current spectroscopic method for monitoring the water quality COD index, and the current ultraviolet-visible spectrum cannot simultaneously measure the water quality ammonia nitrogen, total phosphorus and total nitrogen simultaneously, and provide a method for constructing a water quality index prediction model and a water quality index Monitoring methods.
- the present invention solves its technical problems, and adopts a technical solution that is a method for constructing a water quality index prediction model, which is characterized by including the following steps:
- Step 1 Collect several water samples of various water quality types and various water quality index concentrations as the sample water samples, and obtain the required water quality indexes of each sample water sample respectively, and the required water quality indexes are at least one;
- Step 2 For each sample water sample, measure its corresponding spectrum to obtain the original spectrum and obtain its physical parameters;
- Step 3 Perform at least two digestions on the sample water sample, and measure the corresponding spectrum for each digestion to obtain each digestion spectrum, and obtain the digestion parameters of each digestion and the physical parameters of the sample water sample after each digestion ;
- Step 4 According to the original spectrum of each sample water sample, each digestion parameter, each corresponding physical parameter, each corresponding digestion spectrum and the required water quality index of the corresponding sample water sample, construct each water quality index forecast for each required water quality index model.
- the required water quality indicators preferably include COD and/or AN and/or TP and/or TN;
- the prediction models of each water quality index are a water quality COD prediction model and/or a water quality AN prediction model and/or a water quality TP prediction model and/or a water quality TN prediction model.
- step 2 and step 3 the corresponding spectra are ultraviolet-visible absorption spectrum and near infrared absorption spectrum. This is the most commonly used absorption spectrum in the field of monitoring, which can save system development costs.
- the digestion is wet digestion or electrochemical digestion or ultraviolet digestion or microwave digestion. This is an existing digestion method that can save system development costs.
- the digestion parameters include the selected reagent, digestion time and pressure;
- the digestion parameters include pH value, electrode area, voltage value, current value and digestion time.
- step 3 in the at least two digestions, the digestion rate for the target pollutants in each digestion is less than 100%. This is because if the digestion rate reaches 100%, the target pollutants disappear, and the data is no longer meaningful.
- the sample water sample is placed in the optical measurement cell for measurement during measurement;
- step 3 during the digestion, the sample water sample is placed in the digestion tank for digestion.
- the purpose is to keep every measurement of each sample water sample in the same environment.
- the physical parameters include pH, temperature, turbidity, conductivity, and dissolved oxygen.
- the corresponding spectrum in order to improve the monitoring accuracy, the corresponding spectrum, the method used for digestion, the choice of digestion parameter types, the choice of physical parameter types, and the environment during measurement and digestion correspond to the construction of prediction models for various water quality indicators.
- the beneficial effect of the present invention is that the above water quality index prediction model construction method and water quality index monitoring method, due to the use of digestion, can make the water samples (including sample water samples and water samples to be measured) not directly measurable (here, measurement Refers to the substance represented by the spectrum) becomes measurable, thereby fundamentally reducing the measurement error, and multiple water quality index prediction models can be established at the same time, so that they can be measured separately according to a set of measurement data during actual measurement Various required water quality indicators save the number of water quality indicator monitors and the monitoring steps.
- the method for constructing a water quality index prediction model according to the present invention includes the following steps:
- Step 1 Collect several water samples of various water quality types and various water quality index concentrations as the sample water samples, and obtain the required water quality indexes of each sample water sample respectively, and the required water quality indexes are at least one;
- Step 2 For each sample water sample, measure its corresponding spectrum to obtain the original spectrum and obtain its physical parameters;
- Step 3 Perform at least two digestions on the sample water sample, and measure the corresponding spectrum for each digestion to obtain each digestion spectrum, and obtain the digestion parameters of each digestion and the physical parameters of the sample water sample after each digestion ;

- each water quality index prediction model is a water quality COD prediction model and/or a water quality AN prediction model and/or a water quality TP prediction model and/or a water quality TN prediction model.
- the water quality indicators can also be water quality indicators such as water quality permanganate index, nitrate nitrogen and nitrite nitrogen, biochemical oxygen demand, total organic carbon, dissolved organic matter, turbidity, and color.
- the corresponding spectra are preferably ultraviolet-visible absorption spectra and near infrared absorption spectra. This is the most commonly used absorption spectrum in the field of monitoring, which can save system development costs.
