Soil Infiltration Experimental Study On Polluted River Water

In recent years, with the urban construction and development, the industrialization process of Zhengzhou City have speeded up to promote social progress and imp-roving people's living level. A lot of sewage form township are discharged to river as economic development. As in the Huang-Huai River region in the province of regional economy is relatively underdeveloped, so the control of river water pollution caused great pressure on local governments, cities and small towns of the wave-scale sewage treatment, but in dealing with the issue of river water pollution problems still exist. Therefore, the study on sewage treatment problems in the river,, carried out experimental research and problems.Soil infiltration experimental deals with Jaluhe River sewage as an example.Treatment of soil leaching method using river water were studied by a single fill and soil-filler combination, the soil percolation test to determine the law of small reaction zone from the soil-Haydite composite structure, taking into account the removal of rates and socio-economic factors, to determine the soil percolation test follow-up method in the reaction zone by the soil-ceramics and soil-zeolite compositions. Dynamic adsorption tests that:(1) Soil filtration assay medium for total phosphorus and soil removal effect of COD was significantly higher than the single filler removal, for removal of ammonia, zeolite, Haydite slightly better than the soil The soil was significantly higher than the other two fillers. (2) Soil filtration assay for the experimental data show that a single medium:Haydite for ammonia nitrogen, total phosphorus, and the average removal rates of CODCr 79.84%,45.45%, 37.6%, the overall removal efficiency was significantly better than the other three types of packing; Zeolite on the ammonia removal efficiency of 81.70% on average, but the average removal of total phosphorus below 30%. Experimental studies have shown that small scale:soil infiltration system is stable, the ammonia effluent concentrations were less than 50mg/L, to meet national standards for sewage discharge an A; average effluent total phosphorus concentration of 0.61mg/L, the average removal Rate of 92.21%. The total effluent concentration of less than 1m g/L, which meet the national standards for sewage discharge level B; CODCr average effluent concentration of 38.33mg/L, the average removal rate was 88.53%, and the effluent can meet the national standards for sewage discharge level B.
