【摘要】 为将只具有提水功能的扬水筒改进成为具有混合和充氧功能的扬水曝气器,先通过小试证明了该扬水曝气器的可行性和有效性,继而研究了影响气弹形成的因素,最后得出了计算最小气室体积的经验公式,并对扬水曝气器的结构进行了优化。更多还原

【Abstract】 The water-lifting barrel was renovated into the water-lifting aerator with the functions of mixing and aeration. Its feasibility and effectiveness were verified by bench-scale test. The factors affecting the formation of gas piston and their effect were studied. The empirical formula was derived for calculation of minimum volume of air chamber, and the structure of water-lifting aerator was optimized.更多还原
