英文摘要	Regarding the iron filing as PRB padding media, this experiment researched the repair effect of iron filing to the groundwater polluted by Cr+6 on condition that different initial concentration of Cr6+ and different flow velocity, and then with the help of the data regression analysis software SPSS, 1stOpt, Excel etc, it studied the regression analysis of Cr6+ removal rate with binary linear and binary nonlinear of the initial concentration and the flow velocity. The results indicated that: the change process of Cr6+ removal rate with initial concentration and flow velocity can adopt regression model analysis of binary linear and binary nonlinear, and in this test, the decision coefficient of the regression model of binary linear(0.825) was smaller than the decision coefficient R-2 of binary nonlinear(0.955), which illustrated, comparing with the regression model of binary linear, the one of binary nonlinear z=(p 1+p3*x+p5*Ln(y)+p7*x<<^>>2+p9*(Ln(y))<<^>>2+p11*x *Ln(y))/(1+p2*x+p4*Ln(y)+p6*x<<^>>2+p8*(Ln(y))<<^>>2+p10*x*Ln(y)) can simulate the change trend of Cr6+ removal rate with initial concentration and flow velocity better.
