新型气浮旋流水处理设备放大实验研究

针对常规水处理设备数量多、体积大、质量大,引起海上平台造价高的不足,发挥气浮和旋流协调作用,研制了新型紧凑式气浮旋流水处理设备,并进行了现场放大设备实验。研究结果表明,设备水力停留时间仅为210 s的情况下,当入口油的质量浓度在240～400 mg/L时,设备除油率可达85%以上。设备处理效果达到国外同类产品技术水平,可为下一步工业化应用奠定基础。

Experimental Study On the Scale-up of An Innovative Compact Flotation Unit for Produced Water Treatment

The conventional water treatment equipment is usually in large quantities, bulky and heavy, which causes the high cost of offshore platforms.In order to solve this situation, a new type of water treatment equipment(compact flotation unit, CFU) was developed. The CFU innovatively utilizes gas flotation and cyclone coordination to improve processing efficiency. The field test of the scale-up equipment was carried out. The results showed that when the equipment hydraulic retention time was only 210 s, the oil removal rate of the equipment could reach more than 85% when the oil mass concentration in the inlet was between 240~400 mg/L. The equipment treatment effect has reached the similar technical level of foreign products, which provide a foundation for further industrialized application.
