| 中文摘要 |
| 采用板框式超滤装置对钢管厂冷却用乳化油废液进行处理试验,结果表明,板框式超滤器在压力低于0.40MPa,运行温度40-45℃条件下,配用PSF超滤膜,可将乳化油废液一次连续浓缩,含油量由2%增至40%-50%,体积浓缩20倍,超滤平均通量15-20L·(m2·h)-1;渗透液中含油量降至100mgL-1以下,油分截留率大于99%,COD截留率大于90%. |
| 英文摘要 |
| The emulsified oily wastewater from steel tube factory was tested by the plate and frame ultrafiltration device.It was found that plate and frame ultrafiltration device with polysulfone ultrafiltration membrane can concentrate emulsified oily wastewater effectively when operation pressure is less than 0.4MPa and operation temperature is 40-45℃,the oil concentration increases from 2% to 40%-50%,the average flux rate is 15-20L·(m2·h)-1,the oil concentration of the treated effluent through this process is reduced below 100 mg·L-1,rejection rates of oil and COD are more than 99% and more than 90%,respectively. |
