采用于湿交替方法，用5层倾斜土槽装置填充蜂窝煤渣和砂壤土等附着材料，探讨3种不同挡水板高度（90mm、60mm和30mm）处理对模拟生活污水污染指标去除率的影响。结果表明：3种处理对污水中BOD5、COD、TP的去除率均在87％～95％以上、TN的去除率在69％～80％之间，对COD、TP平均去除率的影响不显著，但对BOD，和TN有显著影响，其平均去除率的顺序为：去除率90mm≈去除率6m〉去除率30mm本试验条件下采用60mm为最适合水板高度，以满足装置一定污水流量的处理负荷。

Through alternation of wetting and drying method, the effect of 3 kinds of different baffle board heights （ 90mm, 60mm and 30mm） on removal rates of contaminant indexes of simulative domestic wastewater are studied by using five layers Slant- ed - Soil - Chamber devices with honeycomb cinder and sandy loam soil and so on as adsorbing materials. The results indicate that the removal rates of BOD5, COD and TP are above 87% - 95%, of TN is between 69% and 80% of the wastewater in the 3 kinds of treatments. The differences of average removal rates（ARR） of COD, TP are not remarkable, but that of BODs, TN are remarkable. The order of their ARR is as follow ： at 90mm ≈ at 60mm 〉 at 30mm. Therefore, 60mm is the optimal baffle board height under this experiment condition and meet a certain discharge wastewater treatment load.
