A kind of improved biological aerated filter with a pipe out side of the filter , where the waste water would be aerated to treat urban waste water, is researched during three months.

曝气生物滤池简称BAF，是20世纪80～90年代在普通生物滤池基础上，借鉴给水滤池工艺原理而开发出的污水处理新工艺。

The supply strategy of dissolved oxygen and its concentrations, distributions in filter bed influence the biological performance of aerobic filter dramatically.

溶解氧是影响好气滤池生物作用的一个关键因素，溶解氧的供给方式和滤床内溶解氧浓度分布及大小均对滤池的生物作用产生较大影响。

The experiment is very hard to remove phosphor. The best backwash cycle is 6 hours and use air water backwashing. The treatment efficiency could come back to 70% after 12 hours behind the backwash.(5)The removal rate of double-layer medium BAF is better.

5与单一炉渣填料的生物滤池的处理效果相比，本试验的双层填料曝气生物滤池显著提高了出水水质，尤其提高了滤池对NH_3-N的处理效果：滤池对COD_的去除率平均提高了10％，对NH_3-N的去除率平均提高了将近30％。

Within the operating range in this study, the oxygen transfer coefficient using enriched oxygen aeration is 1.3 times higher than that in conventional oxygenic aeration.

采用富氧膜法制备O2体积浓度为28.8%的富氧气作为曝气源，研究了富氧气在水中的传质特性，考察了富氧气曝气对有机物降解的效果，研究了污水浓度、曝气量等因素对生物反应器效能的影响。

In the later transformationand evolution, some were oxidided and biodegraded, some were mixed up with the gas with the same source and dif-ferent maturity.

在后期的改造和演化中，有些煤型气遭受细菌的氧化和降解，形成生物降解气；有些则与同源不同成熟期的天然气发生混合作用。

Similarly, those for biodegrading ethanol are temperature of 25~30℃,pH of 5, flux of 0.06m3/h, and the maximal elimination capacity of 712.9g/m3 reactor/h . Moreover, the reactor for degrading ethyl acetate or ethanol is also stable in the long operation.

One can easily find that from the experimental results: the course, in which ethyl acetate or ethanol degraded in bioreactor, is "reaction limited". The optimal conditions for biodegrading ethyl acetate are temperature of 25~30℃,pH of 7, flux of 0.05m3/h, and the maximal elimination capacity of 472.23g/m3 reactor/h .

气升式环流生物反应器降解乙酸乙酯的优化条件为：反应器内温度25~30℃，pH=7，进气流量为0.05m3/h，处理能力最大为472.23g/m3/h，且连续长时间的操作反应器的稳定性一直很好。

By oil-source correlation, it is clear that the Qinggao oil fields main oil-source comes from source rock of S4 section of BoXing sag; The geochemical index of hydrocarbon gas inflects it has the character of petroliferous gas and has suffered from different extent of biology degradation.

通过油源对比，说明高青油田油源主要来自博兴洼陷沙四段烃源岩；烃类气的地化指标反映为油型气，且都不同程度遭受生物降解。
