脆弱刚毛藻对水体中三种苯系物的去除效果

采用L934正交设计法,研究了脆弱刚毛藻Cladophora fracta (Dillw.) Kuetz.]对水体中3种苯系物苯、甲苯和二甲苯的去除作用.结果表明,脆弱刚毛藻对苯、甲苯和二甲苯的去除率分别为46.6写,13.6%和7.4 Yo.分析不同处理条件对脆弱刚毛藻对苯去除率的影响,各因素极差值大小依次为:温度>处理时间>藻体重量,温度是影响去除笨效果的主要因素.在刚毛藻去除甲苯的实验中,各因素R值大小依次为处理时间>藻体重量>温度,主要影响因素是处理时间.而对于二甲苯,藻体重量则是最主要的因素.

Removal Effect of Cl a dop hor a Fr act a on Benzene, Toluene and Xylene

Removal effect of Cl adophora fracta (Dillw. ) Kuetz. on benzene, toluene, and xylene is studied using L9 (34 ) orthogonal design. Results show that the removal rates of benzene, toluene, and xylene are 46.6 %, 13. 6 %, and 7. 4 %, respectively. The effect of the different processing conditions of C. fracta on benzene removal rate is analyzed. Analysis indicates that the temperature is the primary factor of the removing effect and the exposure time and algal weight take the second and third places. For the removal of the toluene, the main factor is the exposure time and the next is the algal weight and temperature. But for xylene,the algae weight is the most important factor .
