The results of a study to find a relationship between the chloroform content in drinking water and the parameters characterizing water quality over an eighteen-year period of the infiltration water intake operation are presented. To increase the reliability of the model, the annual cycle is divided into two periods: an extended flood, including four months (April - June) and a period of low water and permanent watercourse, including eight months (August - March). Three time series were formed from the initial data: from the monthly average values of the parameters for the entire observation period; as a result of averaging the parameter values corresponding to each year; average values characterizing the low-water period and permanent watercourse for the entire observation period. It was found that the period of low water and permanent watercourse can be described by regression equations characterized by a smaller value of the average approximation error and a large value of the correlation coefficient. It was revealed that April introduces a significant stochasticity in the annual period. It is shown that the results obtained can be used to assess the value of the chloroform content in drinking water.
A relationship was found between the chloroform content in drinking water and the parameters characterizing the water quality (turbidity, chromaticity, oxidizability) during the extended flood period (March - June), isolated from the eighteen-year period of the infiltration water intake operation. Two time series were formed, including the monthly average values of the parameters for the entire observation period (72 values) and the averaged values of the parameters corresponding to each year (18 values). Two time series were formed, including the monthly average values of the parameters for the entire observation period (72 values) and the averaged values of the parameters corresponding to each year (18 values). Correlation-regression analysis showed that none of the parameters have a decisive significance for the chloroform content. Multiple correlation-regression analysis revealed that the regression equation for the time series of the averaged values of the parameters corresponding to each year is statistically reliable, is characterized by an acceptable mean error (about 12%) and can be used to assess the chloroform content in drinking water.
Проведена попытка оценки влияния параметров качества воды водоисточника (мутность, цветность, окисляемость) в величины дозы хлора и содержания тригалогенметанов в питьевой воде в периоды годового цикла (весна, лето, осень, зима). Установлено, что использование системы линейных алгебраических уравнений показывает, что в периоды годового цикла происходит перераспределение вклада исследуемых параметров в величины дозы хлора и содержания тригалогенметанов. В отличие от мутности и цветности, вклады которых могут принимать как положительные, так и отрицательные значения, окисляемость во всех случаях повышает значения рассчитываемых параметров.
