| 中文摘要: |
| 研究不同季节及厌氧处理对奶牛场污水主要污染指标的影响，结果显示，不同季节和厌氧处理均对奶牛场污水中主要污染素产生显著影响。原场污水中春、夏季各污染素含量高于秋、冬季，经厌氧处理后的污水中冬、春季主要污染指标含量高于夏、秋季。经厌氧处理后，污水中的CODcr，NH4+-N、氮尧锌等主要污染指标含量均明显下降。 |
| 英文摘要: |
| The effects of different seasons and anaerobic treatment on the key pollution indicators in cattle farm sewage were studied. The result showed that different seasons and anaerobic treatment had significant influence on the main pollution factors of wastewater. The contents of polluted ingredient in spring and summer were higher than those in autumn and winter. However, after anaerobic treatment, the key pollution indicators in winter and spring were higher than those in summer and autumn. After anaerobic treatment, the key pollution indicators in sewage including CODcr, NH4+-N,nitrogen and zinc decreased significantly. |
