首先，以嘉南藥理科技大學水療館之藥浴池、龜丹溫泉水、關子嶺溫泉水，分別進行電解水及次氯酸鈉之消毒，結果顯示，兩者消毒後，自由餘氯濃度相同，總菌落數電解水與次氯酸鈉相差為10 CFU/ml至20 CFU/ml，兩者並無太大的區別，但次氯酸鈉會造成水質色度下降，電解水則不會有此反應。
本研究利用電解消毒技術，於游泳池及香精池進行消毒研究，首先於台中微風廣場東峰游泳池香精池進行研究，結果顯示，自由餘氯濃度控制在0.6 mg/L，方可將總菌落數抑制在法規標準之下，並以問卷方式，詢問遊客兩種消毒藥劑使用後之看法，發現次氯酸鈉會造成遊客皮膚有乾癢的症狀，而電解消毒液則不會有此症狀；接下來於嘉南藥理科技大學水療館之藥浴池進行評估，實驗結果顯示，自由餘氯控制在0.5 mg/L時，即可將總菌落數抑制在法規標準內。在加藥成本方面，若以符合微生物管制之考量前提下，針對本研究利用電解消毒技術在嘉南藥理科技大學水療館藥浴池進行消毒，每噸水處理費用為2.79 NT的加藥成本。
The purpose of this study was to explore the water qualities of hot springs and swimming pools. A very traditional way of disinfection is the addition of chlorine. However, chlorine may pose risks in the process of storage and transportation. In this study, we focused on the application of electrolysis technology to the water disinfection of hot springs and swimming pools and analyzed the disinfection effects and costs of electrolyzed water and sodium hypochlorite in waters of different qualities. To explore a more extensive use of electrolyzed water, electrolyzed water was used to wash fruits and vegetables for the observation of residues.
First, electrolysis disinfection and sodium hypochlorite disinfection were respectively conducted in the dipping vat of the spa in Chia Nan University of Pharmacy and Science and the hot spring waters from GueiDan Hot Spring and KuanTzuLin Hot Spring. The results showed that after disinfection, the concentrations of free residual chlorine were the same, and the difference in total bacterial counts between water disinfected with electrolysis and sodium hypochlorite was only between 10 CFU/ml and 20 CFU/ml, which was a very small difference. However, sodium hypochlorite would worsen the water color, while electrolysis disinfection wouldn’t.
In this study, electrolysis disinfection technology was applied to a swimming pool and an essence pool of DongFen Swimming Pool of Breeze Center in Taichung, for which permission was first obtained from the operator. The results showed that only when the concentration of free residual chlorine was kept at 0.6mg/L, could total bacterial count be suppressed under legally allowable level. Questionnaire survey was conducted, asking pool visitors about their feelings of two different disinfection methods. It was found that respondents complained of dry and itchy skin caused by sodium hypochlorite, compared with electrolysis disinfection which didn’t have this kind of problem. After that, the same experiment was conducted in the dipping vat of the spa in Chia Nan University of Pharmacy and Science. The results showed that when the concentration of free residual chlorine was controlled at 0.5mg/L, the total bacterial count could be suppressed under legally permissible level. In terms of cost, when the microbial control regulations were taken into account, the cost of electrolysis disinfection for each ton of water was NT2.79.
