摘要
人工湿地处理污水系统植物床内各监测点的上、下层 C O Dcr值虽有一定的差别,但经过成对平均数比较分析发现这种差别并未形成明显的趋势。污水在植物床基质中流动时,随着迁移距离的延长,其中的 C O Dcr的降解速率呈现先快后慢的趋势,根据形成的动态变化曲线,建立了 C O Dcr在植物床内沿程动态变化模型: C L= Coexp(4629×10- 5 L2- 001567 L,0≤ L≤100)。经验证,模型预测值与实际监测值呈非常显著相关(df= 4,r≥09946> r00005(4),r00005(4)= 09741)。
Based on the dynamic experiment of variation of water quality in constructed wetland system the laws of COD cr removal from wastewater in the system,we have set up a model below:C L=C oexp(4 629×10 -5L 2-0 01567L),0≤L≤100 Using this model we can forecast the concentrations of COD cr in the system,and there exists a good relativity between forecasted values and monitored values(df=4,r≥0 9946>r 0 0005(4) ,r 0 0005(4) =0 9741) l
