Abstract:	全球吹起環保節能風潮，除了可再生能源、風力發電、太陽能發電、水力發電外，廢棄的滷水也是未來在再生能源中所被關注的項目之一。在海水淡化解決淡水資源短缺的同時，大量的濃海水排放也帶來了環境問題。本研究利用海水淡化之廢棄物、曬鹽場製鹽所產生的高濃度滷水和家庭廢棄生廚餘堆肥製成之液肥作為電解液進行能源開發研究。首先，先取得滷水為電解液，利用電極集中、交叉、水體循環等變因，應用於第M421605號專利「可充放電電池」進行研究，研究結果指出單片碳與三鎂片能產生電壓1.75 V及電流2.3 mA效果最佳。集中式電壓為1.86 V及電流9.5 mA，交叉式電壓1.46 V及電流15.8 mA，循環利用流速以每分鐘1L速率，電壓可達1.85伏特，電流為12.6毫安培，發電時間可超過8小時。生廚餘液肥利用電極環繞式，有機酸pH值降低0.2電壓會增加0.8伏特，可得到最大輸出功率，電壓2.0V及電流1.7 mA亦可達到發電效果。本研究不僅可將廢棄物再利用更能發展新的替代能源，可取代一般電池藉此減低一次和二次電池等之使用量而達到節能減碳、維護環境、低污染、提升回收再利用和再生能源之價值以符合現今環保潮流。 Worldwide, environmental protection and energy conservation are topics of paramount importance nowadays. Aside from wind power, solar power and water power which are common renewable energies, waste brine could also be a subject worthy of study. Desalination could be a way of solving an emerging problem of shortage of freshwater supply. However, there is a significant environmental drawback associated with the desalination process, namely, the production and discharge of concentrated seawater back into the sea. Other than using waste water from the desalination process as electrolytes, highly concentrated brine from Salter and liquidized fertilizer made from domestic food waste could also be used by the Energy research and development. In this research, brine was used as electrolytes and applied to the patented rechargeable battery No.M421605 by connecting electrodes and circulating water. Observations have shown that a single piece of carbon and three magnesium ribbons obtained the best result, with a voltage of 1.75 V and a current of 2.3 mA, centralized voltage of 1.86 V and current of 9.5 mA, and the cross-voltage of 1.46 V and with current of 15.8 mA. By circulating the flow rate of brine at 1L per minute, the voltage could increase up to 1.85 volts and 12.6 mA of current, in this manner, power can be generated for more than 8 hours. The raw food waste utilizes the surrounding of electrode, which decreases the pH value of butyric by 0.2 and correspondingly increase the voltage by 0.8V, thus, maximizing the output effect. Furthermore, when the voltage is at 2.0V and the current at 1.7mA, it is already capable of generating power. The research not only proves that waste can be used for generating renewable energy, but can also be a replacement for normal cell batteries, thereby encourages in the reduction of the use of disposal cell batteries and secondary cells. This could achieve today’s trend in reducing energy consumption, lessening pollution, increasing the amount of recyclable materials and the value of renewable energy
