摘要
采用原位高铁酸氧化法处理页岩气采出水,考察反应初始p H、反应时间(t)、催化剂与氧化剂配比(Wi)、氧化剂浓度(Ci)及反应温度(T)对该废水处理效果的影响。结果表明:在反应初始p H为11、反应时间为30 min、催化剂与氧化剂配比为0.15、氧化剂为3.9 g/L、反应温度为20℃的条件下,COD的去除率为57.98%。通过响应曲面法对初始p H、反应时间、催化剂和氧化剂配比进行优化,优化后条件为:初始p H为10.5、反应时间为35min、催化剂和氧化剂配比为0.14时,COD去除率达到58.86%。
In-situ ferrate oxidation was used in the treatment of shale gas produced water.The effects of initial pH,reaction time,ratio of catalysts to oxidants,oxidant concentration and reaction temperature on the treatment result were explored.The experimental results showed that the removal rate of COD was 57.98%under the condition of initial pH 11,reaction time 30min;ratio of catalysts to oxidants 0.15,oxidant concentration 3.9g/L and reaction temperature 20℃.Response surface.methodology was used to optimize the reaction conditions including initial pH,reaction time,ratio of catalysts to oxidants.Under the optimized condition of initial pH 10.5, reaction time 35min,ratio of catalysts to oxidants 0.14,the removal rate of COD was 58.86%.
