A new pilot process of wastewater treatment by using membrane method H -O scheme (hydrolysis- acidification-aerobic)has been carried out.Its main point is to improve the biological treatment system for the refinery wastewater which could not be denitrificated by the recirculated sludge,and the water quality of the ef- fluent is unsteady.The new operational mode runs in H -O -R process by changing the secondary semidenta- tion to submerged biosemidentation.The results show that the water quality of the effluent can meet the require- ments of the national and local water dischange standards such as DB44/56—1992.
