摘　　要： 从活性污泥中筛选到1株絮凝活性很高的菌株MY-88。研究结果表明，MY-88的初始培养pH为6．5～7．0，最适温度为25～35℃，最适碳源为葡萄糖；在摇床速度为180r／min时，其絮凝率达100％。Na^＋、K^＋、Ca^2＋、Fe^3＋均有较好的促絮凝作用，其中Ca^2＋尤为显著，使絮凝率这99．6％。MY-88在较大的pH、温度、摇床速度、搅拌速度、水样pH等范围内均具有较高的絮凝活性，显示出良好的应用前景。 A strain MY-88 possessing very high flocculation was screened from activated sludge. The study showed that the initial culture of MY-88 was pH 6.5-7.0, and optimum temperature was 25-35℃, and the best carbon source was glucose, when it was cultured in shaker at 180 rpm, the flocculation rate was 100%. Na^＋、K^＋、Ca^2＋ and Fe^3＋ facilitate the flocculation, especially Ca^2 ＋ , and it alone made the flocculation rate at 99.6 %. MY-88 has fairly high flocculation activity at relatively wide range of pH, temperature, shaker＇s rpm, mixing speed, and pH of water sample, demonstrating good application prospects.
