地下水封石洞库裂隙水处理工艺设计

Process Design of Fissure Water Treatment in Underground Water-Sealed Caverns

针对地下水封石洞库裂隙水主要污染物为悬浮物、微生物及所储存介质(油或气)且裂隙水水量大、水温低,处理回用存在一定难度的情况,对地下水封原油洞库裂隙水采用斜板除油、气浮、二级过滤处理工艺,对地下水封丙烷洞库采用解脱气、曝气生物滤池、二级过滤、超滤处理工艺。实际运行结果表明,两地下水封洞库裂隙水处理均达到了相应污水回用指标,裂隙水回用率均达到了70%以上,节约了水资源。

Aimed at the main pollutants in the fissure water of the underground water-sealed caverns are suspended solids, microorganisms and stored media(oil or gas) and the fissure water has a large amount of water and low temperature, it is difficult to treat and reuse. The fissure water in the underground water-sealed crude oil cavern was treated by CPI separator, air flotation and secondary filtration, while the underground water-sealed propane cavern was treated by degassing, biological aerated filter, secondary filtration and ultrafiltration. The actual operation results showed that the fissure water of the underground water-sealed cavern in the two places had reached the requirements for wastewater reuse index, and the fissure water reuse rate had reached more than 70%, which saved water resources.
