复氧改性土壤对污水处理效果的实验研究

Experimental Study on Effect of Re-oxidizing Soil on Wastewater Treatment

以生活污水为研究对象,按照一定比例充分混合土壤颗粒、砂石、凹凸棒土、锯末粉等基质构成改性土壤,填充到有机玻璃柱中进行污水入渗,土壤溶液采样器原位采集不同层位的土壤水样品,收集土柱底部出流水样品,对水样进行COD、TN、NH_3-N、TP参数测定。实验结果表示土壤的质地得到了改善,对生活污水的N、P处理效果较好,具有很大的发展潜力。

The soil samples, sand and gravel, attapulgite and sawdust were modified soil, filled with organic glass column for sewage infiltration, soil sample the COD, TN, NH3-N and TP parameters of the water samples were measured. texture was improved, the domestic sewage N, P treatment was better with great mixed with a certain proportion to form a sampler in situ collection of different and Experimental results showed that the soil potential for development.
