Preparation of a recyclable demulsifier for the treatment of emulsified oil wastewater by chitosan modification and sodium oleate grafting Fe3O4

The Sequencing Inclined Dynamic Membrane Biological Reactor (SIDMBR) was investigated on a pilot scale for 60 days of emulsified oil wastewater treatment at zero excess sludge discharge. Results indicate that at hydraulic retention time of 24 h, the average removals of chemical oxygen demand (COD), ammonia nitrogen and oil are 66.83, 64.2 and 70.8% in 1~60 days, respectively. The membrane flux, biofilm quantity, and extracellular polymeric substances (EPS) content begin to change after 20th, which indicate that membrane fouling has occurred.

In order to improve the steady permeate fluxes during the emulsified oil wastewater treatment using precoated dynamic membrane, a coupling process of precoating dynamic membrane with ultraviolet photocatalysis was studied. Impacts of the ultraviolet light power, pH values and the oil concentrations on improvement of the steady permeate fluxes were investigated. The results showed that the ultraviolet photocatalysis effectively improved the steady permeate fluxes and reduced the membrane fouling resistances during the emulsified oil wastewater treatment. The dynamic membrane steady membrane fluxes increased with the rise of ultraviolet light power and decrease in liquid pH values and oil concentrations. Impact of the ultraviolet photocatalysis on the oil retention ratio of precoating dynamic membrane was not obvious.
