Abstract： |
| In plant silage effluent, CODcr and NH4+-N are in high concentration, which has caused seriously pollution in some areas. Bio-zeolite system, removal of CODcr and NH4+-N, was selected to treat the corn silage effluent in dairy farm. The following results were obtained: beginning the biofilm,after 23th day, the removal efficiency of CODcr and NH4+-N was over 70% and 80%，which reveals the stable for the removal of CODcr and NH4+-N by bio-zeolite system after the biofilm maturation. When the gas to liquid ratio was 2:1, hydraulic retention time was 12h, the biofilm has the best of activation and the highest removal rate of organic pollutant. The removal rate of NH4+-N decreased to 32.7% when the concentration of CODcr increased to 280mg/L.The removal of NH4+-N was limited by organic load and the decrease of DO concentration, organic degradation, severely inhibited the growth of nitrifying bacteria. |
