| dc.description.abstract | 溶氧在自然水體中為水質優劣的重要指標，簡易式微細氣泡產生裝置由市售硬質塑膠管材及抽水馬達組裝而成，利用柏努利(Bernoulli)定理，改變管內水流速度，進而將空氣導入水中，產生直徑小於600μm的微細氣泡，提升水體溶氧量以改善水質環境。
本研究先分析1/8馬力至1馬力四種動力規格，共76種模組之簡易式微細氣泡裝置的增氧效果，以測量氣泡直徑，判斷系統之曝氣能力。其次，探討裝置之增氧效率、影響範圍等水質改善能力，以明確量化裝置適用範圍與操作規範；並與市面上常見之增氧設備做經濟性比較，完成多規格的微細氣泡產生裝置之基本資料建立。 依裝置標準化試驗結果，標準氧氣轉換效率以1hp動力的效果最佳，在淡水中為14.3 kgO2/hr，在海水中為63.1 kgO2/hr，明顯得知利用在海水中之曝氣效果優於淡水，而總體氧氣質傳係數及吸氣量與動力成正比，標準曝氣效率及氣泡粒徑則與動力成反比。至於本裝置應用於深水域之效果較淡水域顯著，增氧擴散範圍與水深成正比，於5公尺深水域之增氧擴散範圍可達半徑30公尺。 | zh_TW |
| dc.description.abstract | Dissolved oxygen quantity serves as an indicator deterring the water quality stand or fall in water field. Simplified Microbubble Generated Device was assembled by a pump and PVC tubes, adopting Bernoulli's equation, accelerating the water velocity in the pipe to transfer air into the water. The microbubbles produced by this derive were smaller than 600 um in diameter, increasing dissolved oxygen in water to improve the water quality.
This research analyzed 4 degrees of power supply and 76 models of simplified microbubble generated devices. By measuring the diameters of microbubbles, we estimated the dispersive ability of each combination. Secondly, oxygen increasing efficiency and range were recorded as well for identifying applicable conditions and clarifying operation methods. Finally, with the comparison of other oxygen-increasing equipments, the basic data of different Simplified microbubble generated device was established. According to the results of the experiments, the standard oxygen transfer rate (SOTR) with 1hp power supply reached its top performance. The SOTR was 14.3 kg02/hr in freshwater better that 63.1 kg02/hr in sea water. The Overall oxygen transfer coefficient and the air inhalation were in direct ratio with power supply; the standard aerated efficiency and the diameters of bubbles were in inverse ratio with power supply. The devices showed outstanding effect in deep water since the oxygen diffused area expanded as the depth incrusted. The experiments showed that the oxygen diffused area can access to 30 meter in radius when the device was placed at 5 meter underwater | en |
