目的研究油田采油废水生物处理试验最佳试验条件及最佳试验条件下处理效果.方法生物处理试验分为厌氧试验和好氧试验两部分,分别通过单因素试验确定最佳试验条件,并且确定COD和NH＋4-N的去除率.结果在厌氧生物处理阶段最佳试验条件：进水p H 7.4~7.6,温度37℃,水力停留时间（HRT）20 h,COD去除率平均为25.7%,NH＋4-N质量浓度平均增长率为18.4%,聚丙烯酰胺（PAM）的平均去除率为10.3%,油的平均去除率为21.0%;在好氧生物处理阶段,最佳试验条件：进水p H 8.0~8.2,温度34~35℃,HRT 18 h,COD去除率平均值为51.3%,NH＋4-N平均去除率为93.5%左右,PAM的平均去除率为30.9%,油的平均去除率为58.0%;结论生物处理油田采油废水较化学处理不仅成本低、操作简便,可以取得良好的处理效果,而且能够有效减少化学处理方式造成的污染,达到环境保护的目的.
To explore the influence of rainwater quality on rain utilization projects the rainwater of building roofs community runoff and municipal outlets which were taken from Hunnan New District of Shenyang was detected and analyzed for one year. The results show that the main pollutants affecting the quality of the rainwater are chemical oxygen demand COD and suspended solids SS which is especially obvious at the beginning of rainfall. With the duration of the rainfall water quality improves.The contents of COD and SS in municipal outlets are the highest which are 167 to 249 mg/L and 119 to 332 mg/L respectively. The contents of COD and SS are 27 to 85 and 106 to 269 mg/L in community runoff 15 to 80 and 50 to 153 mg/L in the rainwater of building roofs.NH4＋-N concentrations of the three sampling sites are 1.7 to 5.2 3.7 to 18.2 and 5.2 to 25.6 mg/L.
