| 摘 要： | 应用辐射流动室（Ｒａｄｉｃａｌ Ｆｌｏｗ Ｃｈａｍｂｅｒ，ＲＦＣ）技术宣地研究水力剪切力对硝化细菌在聚苯乙烯（ＰＳ）载体表面固定的。发现水力剪切力直接影响硝化细菌的固定。当作用于ＰＳ表面的水力剪切力大于８．０Ｎ／ｍ＾２时，硝化细菌基本不能在ＰＳ表面险境着；水力剪切力小于８．０Ｎ／ｍ＾２时，硝化细菌的固定程度随剪切力的减小而加强，直至达到最大，实验表明辐射液动室技术为定量研究生物膜形成及控制与水力剪

| Abstract: | This paper quantitatively studied the effect of hydraulic shear stress on adhesion of nitrifying bacteria on PS surface using Radical Flow Chamber.It was found that hydraulic shear stress closely affected adhesion of nitrifying bacteria.As the hydraulic shear stress was greater than 8.0N/m 2,nitrifying bacteria were not able to adhere to PS surface.When the hydraulic shear stress exerted on PS surface was less than 8.0N/m 2,adhesion of nitrifying bacteria was increased up to its maximum with decreasing the hydraulic shear stress.Experiments show that Radical Flow Chamber technique provides a mean for study of quantitative relation between bacteria adhesion and hydraulic shear stress in a flowing system. |
