| dc.description.abstract | In recent years, with climate change, disaster prevention and rescue has become one of the peacetime tasks of the Taiwan military, and the use of Taiwanese military-style water purification equipment to cooperate with the Central Disaster Response Center to assist in water purification operations has also become normal. The motivation of this study is how to provide water in a timely and timely manner and quickly, and comply with the ＂Drinking Water Quality Standards＂ formulated by the Environmental Protection Department of the Executive Yuan, so as to provide sufficient and safe drinking water to maintain people′s basic survival and living needs, and reduce the impact of unexpected disasters.
In this study, three water areas including Shimen Reservoir in Taoyuan City, Guanyin Beach and Gongliao Yan in New Taipei City were mainly used as water intake sources, and the influence of RO film fouling and blockage on water production efficiency was discussed by sampling different water quality, using equipped filtration equipment, and measuring water quality indicators for the inlet water taken and the filtered outflow water, and then discussing the effect of RO film fouling and blockage on water production efficiency through the difference in inlet and outlet water quality parameters and the influence of different water quality parameters on filtration efficiency. Through relevant data and statistical analysis, the correlation and significance between water quality parameters and RO membrane occlusion were discussed.
Based on the comprehensive results, it can be seen that the changes of raw water and clean water quality parameters after filtration in different regions affected the formation of RO film fouling and blockage, and the water quality of Shimen Reservoir was highly correlated and significantly affected by the turbidity value of water and RO membrane obstruction in the 16th hour of continuous operation of the system container. The water quality of Guanyin Beach was highly correlated and significantly affected by the turbidity value of the water and RO membrane occlusion in the 8th hour of continuous operation of the system container. However, the water quality of Gongliaoyan was highly correlated and significantly affected by the TDS value and RO membrane blockage in the 24th hour of continuous operation of the system container, and it can be determined that with different water sources, the parameter values of different water quality (such as turbidity value and TDS value) change, resulting in easy fouling and blockage on the surface of RO membrane, which in turn affects the filtration efficiency and water production efficiency.
By making suggestions on the three aspects of policy, implementation and hardware facilities, in terms of policy, using Taiwan′s defense department to allocate water purification equipment, the areas that can be used for water supply can be listed as a support list in advance, so as to facilitate the rapid and timely completion of water supply tasks in the event of disasters, and in water source sampling, general fresh water is more suitable than seawater, because seawater contains high salinity, high concentration of inorganic substances and microorganisms can easily cause RO membrane blockage and affect filtration and water production efficiency. In terms of policy, in view of the limited water quality extraction environment, although the water bodies of these three sites are different, the water samples obtained are still relatively limited, it is recommended that more locations can be used as water intake points for comparison, so as to break away from the restrictions of the water quality intake framework, so that the data collected by the Institute can be more diversified and meet the needs of the current situation; In terms of hardware facilities, the filtering equipment and distribution measuring instruments are not diversified enough to be updated according to time to improve the filtration efficiency and detect more accurately. Whether it is in terms of policy, implementation or hardware facilities, if it can be greatly improved and enhanced, it is believed that the accuracy and performance of the follow-up relevant research data can be greatly improved, the values can be closer to the current situation, and the maximum effectiveness of the equipment can be brought into play. | en_US |
