INTRODUCTION (abstract of DSc thesis)
The purpose of the research is to
development of principles and methods for
improving the technology for disinfecting underground drinking water with ultraviolet
irradiation and the substantiation of an autonomous energy supply system for
ultraviolet radiation sources.
The object of research is
autonomous system for disinfection of underground
drinking water with energy supply from solar photovoltaic panels has been adopted.
The scientific novelty of the research is as follows:
-a technology has been developed for the disinfection of drinking water using
water treatment systems based on ultraviolet irradiation,
operating on autonomous
power sources from solar panels;
-the relative energy intensity of the treated water layer was determined using the
finite ratio method, which allows minimizing energy costs in the disinfection process;
-an in-depth model for calculating a solar photovoltaic installation has been
developed, taking into account the impact
of varying external factors, such as solar
radiation intensity, ambient temperature, wind speed and solar panel orientation, on its
energy characteristics;
-a scientific and methodological basis has been developed for the
electrotechnology of water disinfection using a solar photovoltaic installation, which
allows optimizing the power supply system taking into account local meteorological
conditions;
The results of research on the disinfection of underground
drinking water with
ultraviolet rays make it possible to substantiate the composition of an autonomous
disinfection station and evaluate its reliability based on simulation modeling of a solar
photovoltaic station.
Implementation of the research results.
Based on the results of studies to
substantiate the parameters and operating modes of an autonomous system for
disinfecting groundwater drinking water:
a patent was received for an invention from the Intellectual
Property Agency
under the Ministry of Justice for an autonomous installation for water purification
(“Autonomous installation for water purification” IAP 065371-2013). As a result, it
was possible to develop the design of a device that disinfects water using wasteful
energy;
implementation of a UV device control station in Namangan suv
taminoti LLC,
Namang region and Kushkapir tuman suv taminoti LLC, Kharezm region (certificate
of the Ministry of Ecology, Environmental Protection and Climate Change of the
Republic of Uzbekistan N03-03/3-3103 dated July 24. 2023). As a result of the
developed autonomous installations for the disinfection
of underground drinking
water by reducing the consumption of chlorine in volumes of 1 ton 460 kg and
electricity 221493 kW per year, the expected economic effect will be
215953000 soums.
