| Water is the fountain of life, drinking water safety is related to the broad masses of people living and life and health a top priority, In Chinese vast rural areas, need high-quality drinking water, improve water quality and increase water supply in rural areas is an essential safety infrastructure in the village’s daily life and agricultural activities plays an extremely important role.Water treatment disinfection has been the core issue is to ensure microbiological safety of drinking water, and important cell technology, water supply security has become the focus of world attention. A ideal drinking water disinfectant should be safe, efficient, response to the human body non-toxic, non-irritating, and storable, easy to transport, while the use of disinfection operation should be simple, easy to spread. Disinfection of rural water supply and urban water supply are quite different, due to the construction and management of different conditions, to take disinfection methods and equipment are also different. As Chinese rural areas lack of systematic in-depth research, these are different levels of disinfection technology security and usability defects, coupled with disinfectant dosing is not standardized, most of the towns water supply project reach disinfection. Therefore, it is necessary to study the different towns water supply projects of different sizes suitable for use in disinfection technology.In this paper, suitable for village water disinfection technology research: disinfection of existing businesses and products to conduct research, collect information on the advanced disinfection technologies; investigation and analysis of various disinfection methods on scientific research findings. A clear research objectives, based on the development of appropriate survey program, find out the basic situation of water supply project three villages, towns and villages of the therr water disinfection measured, analyzed three towns water supply project construction and disinfection problems in the management of its recommendations. Disinfection of rural water supply project for the status quo, the development of new towns water supply suitable for the disinfection of equipment---UV disinfection equipment, and do indoor tests. Main results are as follows:1.The advantages of business cooperation with research institutions, through laboratory testing and field trials of the combination of filtering integrated automatic monitoring, automatic metering technology, combined with a variety of disinfection technology research, choose a different quality, different sizes of water supply projects, the kinds of disinfection performance and regularity of indicators, research and development and improvement of sterilization equipment, the final selection of pilot projects on the development of field test equipment evaluation, and ultimately determine the appropriate town water disinfection technology and disinfection equipment.2.Through the three villages of the research work and found that the poor condition of rural drinking water, long pipe network, the majority of water far exceeded the total number of E. coli and bacteria; have some water quality testing equipment, but idle, resulting in waste; water and no regular testing of its finished water, the existing problems of these recommendations:We recommend a small concentration of a single village water supply project selection combined with ozone or ultraviolet disinfection, because the actual use of disinfection equipment in the process without considering the purchase of pharmaceutical issues, more convenient, and can ensure the sterilization rate and the microbiological safety of the pipe network. Chlorine disinfection is sodium hypochlorite as a disinfectant, is an efficient, broad-spectrum, safe strong sterilization, kill the virus agent, and its easy to purchase cheaper, disinfection with chlorine has the same effect, suitable for small water supply projects in rural areas promotion.3.Through investigation and analysis of research trials and interior, developed a family of UV disinfection equipment, and has applied for patents in the laboratory test was carried out verification, obtained appropriate technical parameters of the device; we also study the effects of different radiation time under the UV disinfection equipment for the inactivation of E. coli. Confirmed the UV inactivation of E. coli have a good effect. |
