| Abstract: | A biological contact oxidation process was used to treat the low pollution concentration wastewater in a petroleum refinery on a pilot scale. The influences of hydraulic residence time and the flow ratio of gas to water on the treatment effect were then investigated. In the treatment process, biological membrane with high activity was observed. With the sand filter being improved, the removal efficiency of suspended substance increases. The result shows that by using the proposed process, with the conditions of 100min of hydraulic residence time, 3:1 of gas/water flow ratio and 12h of backwashing time for the sand filter, a steady treatment result can be obtained and the effluent can be reused. |
