- 摘要：堆制处理工艺是处理油污土壤的一种强化的生物处理工艺.通过实验室实验, 结果表明:原油降解菌剂投加量6×1012个(CFU)kg(土壤)、营养物投加量为使土壤中C∶N∶P=100∶2.5∶0.25、土壤含水量为饱和含水量的30%—70%、通风量14.0mL/s为适宜处理条件, 此时, 处理2个月, 油去除率在50%以上.在油污土壤中添加的降解菌和营养物种类、数量完全相同时, 堆制处理效率明显高于生物耕翻处理效率;在相同处理时间内, 堆制处理时油去除率可比生物耕翻处理时提高10%以上.在
- Abstract：Composting treatment technology is an enhanced biological treatment technology.By laboratory testing, the results show that the adding amount of crude oil degrading bacteria is 6mL/kg, of nutriment is making C∶N∶P=100∶2.5∶0.25 in the soil, water content is 30%—70% of saturation water content, and appropriate ventilation amount is 140mL/s, at this condition, oil removed rate is up to 50%. Adding totally identical nutriments and degrading bacteria either on kind or on amount, efficiency of composting treatment is obviously higher than one of tilling treatment; During the same treatment time, oil removed rate of composting treatment is higher over 10% than one of tilling treatment. During the treatment, most saturation hydrocarbon and aromatic hydrocarbon was degraded.
