The Application Of Carbon Fiber Biofilm In Acrylon Wastewater Treatment

Because of having excellent Biocompatibility, higher mechanicalcapability and corrosion resistance, carbon fiber can be a good carrier. Thisthesis aims at discussing the effects of surface characteristic and structure ofcarrier on the formation and metabolism of biofilm, the relationship with theeffect of wastewater treatment and the feasibility of using CF as new-stylebiofilm carrier through the study on chemical physical properties of biologicalcarbon fiber,the formation mechanism of biofilm and the capability of wipingoff N-NH₃., COD, SO₄^2-In this thesis, by means of contrast, surface functional groups and thewettability were measured, by using IR,, Scanning Electron Microscope,effects of surface property of carrier on immobilization. multiplication wassystematically studied.At the same time, in different processes,such asnitrify,anoxic- aerobic reaction and two phase anaerobic methods, thecapability of different carrier which wipe off N-NH₃., COD, SO₄^2- wasdiscussed. Results show that: the capability of fixing microorganism on CF isbetter than other materials. The surface acid functional groups, degree of moisture and adsorbability of carbon fiber is prone to multiplication ofmicroorganism and fixing microorganism on the surface of carrier. The surfacefunctional groups of material have an obvious effect up on the activity ofbiofilm. For the immobilization, carbon fiber is like catalyzer.Additionally, in different processes, by means of contrast the capability ofwiping off N-NH₃. COD, SO₄^2-. we consider that CF can be used as biofilmcarrier effectively, through comparing the expense and efficiency of differentbiofilm carrier. This thesis provides scientific ground and new thought for thedevelopment of the carrier.
