今年初,在学习荆门炼厂等试用文丘里喷射器的基础上;我们将原“老三套”处理流程中的全加压溶气浮选改为文丘里喷射回流浮选。通过生产运行和标定,证明了在浮选中使用文丘里喷射器,可使含油污水处理取得较好的效果,因而解决了我厂浮选一直开不好的问题。使经过“老三套”处理的含油污水很快就达到了国家排放标准。 Earlier this year, based on the trial Venturi injectors such as the Jingmen refinery, we changed the full-pressure dissolved air flotation in the old “Third Pilot” process to venturi jet flotation. The production operation and calibration proved that the use of Venturi ejector in flotation can achieve better results in oily wastewater treatment, thus solving the problem that the flotation of our plant has been not good all the time. So that after the “third generation of” the treatment of oily wastewater quickly reached the national emission standards.
