Розглянуто технічні характеристики комплексного аналізатора якості води EZODO 7200 З ОВП-електродом, встановлено рекомендовані діапазони вимірювань гідрохімічних показників для поверхневих вод. Апробовано аналізатор у реальних умовах на природних поверхневих водах. Визначено основні параметри поверхневих штучних водойм для сільської місцевості в Рівненській області. Порівняно склад поверхневих водойм за гідрохімічними показниками якості води.

Title in English

DETERMINATION OF HYDROCHEMICAL INDICATORS OF WATER BODIES USING EZODO 7200 COMPLEX WATER QUALITY ANALYZERS

English abstract

The state of water resources and water supply of the population of Ukraine remains one of the major pressing threats to Ukraine’s national security in the environmental field and the issue of adaptation of water resources management in the face of climate change and the uneven distribution of moisture in the greater territory of our country. The technical characteristics of the complex water quality analyzer EZODO 7200 with ORP electrode are considered, the recommended ranges of measurements of hydrochemical parameters for surface waters are established. The analyzer was tested in real conditions on natural surface waters. The main parameters of surface artificial reservoirs for rural areas in Rivne region are determined. The composition of surface reservoirs is compared according to hydrochemical indicators of water quality. The formation of physico-chemical and bacteriological indicators, as well as quantitative (water levels, costs) indicators of water, surface sources are influenced by the nutrient conditions of the source, pound-geological characteristics of its valley, topographic conditions and associated flow rate, climatic, intensity of snowmelt, precipitation. In recent years, water performance has been affected by human activities: the construction of dams, the discharge of wastewater, the use of fertilizers and their partial washing away by rain and meltwater. The increased content of nitrates in water can also be of mineral origin due to the dissolution of soil salts, such as nitrate. The infiltration of saline solutions into the soil, in particular the topsoil, is the result of anthropogenic activity of the inhabitants of the territories located near these water bodies. The impact is also caused by the application of fertilizers on agricultural lands. In most cases, suspended solids, color, odors and tastes, organic impurities should be removed from the water.
