应用常规的化学分析技术，测定了广西地区具有代表性的2个规模化猪场不同污水处理阶段的污染物含量，并与国家排放标准进行比较，研究每个处理环节污染指数的变化，从而为畜牧养殖业节能减排采取针对性的整改措施提供参考。污染物指标包括：悬浮物（SS）、氨氮（NH3-N）、五日生化需氧量（BOD5）和化学耗氧量（CODcr）。结果表明，2个规模化猪场排出的污水经过一定的污水处理工艺后，猪场1排放的污水不达标，猪场2排放的污水达标；植物塘对污水有明显的净化作用；沉淀调节池和二沉池环节都能有效降低悬浮物（SS）的指标。

Using the conventional chemical analysis technology, the contaminant content in wastewater from different treating stages in two representative large-scale pig farms in Guangxi was determined and they were compared with the national discharged standards. The changes of contamination indices in every treating link were investigated, so as to provide references for taking according measures for energy conservation and emission reduction in the livestock breeding. Contaminants indices included suspended solids (SS), ammonia nitrogen (NH3-N), BOD5 and chemical oxygen demand (CODcr). The results showed that the wastewater discharged from Farm 1 after applying wastewater treatment technology was substandard,but the wastewater discharged from Farm 2 reached standard. Wastewater could be purified by plants grew in the pond. And the suspended solids (SS)could be effectively reduced by the treatment in the settling tank and secondary sedimentation tank.
