Nano carbon fiber is the result of a special process developed a water treatment tech ecological materials , due to their not only has a significant anisotropy , softness, high strength, durability , corrosion resistance , surface area , and low energy consumption, utilization high , easily washable and other characteristics, to adapt to a variety of complex environments such as sewage treatment . This topic will be applied to nano- carbon fiber SBR process for sewage treatment effect were studied and applied study investigated nano carbon fiber biofilm in SBR process is running in a stable condition as well as sewage treatment effects and shock load capacity . Was observed in the test surface nano- carbon fiber forming a large number of three-dimensional structure and rich floc biofilm , which can be long biofilms in water with the water flow and swing. Observed through biological examination of microbial biofilms variety, abundance , filamentous fungi and insects bell interconnected constitute a three-dimensional structure of the biofilm . Experiments show that strong biofilm adhesion easy to fall off , biofilm activity, stable and mature biofilms can resist the impact of different loads . Experimental study identified the nano carbon fiber SBR process operation mode , and its stable operation as well as by the impact loads were studied. Studies show that : nano carbon fiber SBR process the best operating conditions for the water 15 min- aeration 4 h- stirring 2 h- 1 h- water sedimentation 15 min- idle for 30 min. In this condition and stable operation , the influent COD concentration was 167.43 ~ 375.15mg / L, NH 3 -N was 16.2 ~ 31.8mg / L, TN is 19.8 ~ 39.1 mg / L, TP is 3.2 ~ 4.5mg / L, the effluent COD was 12.24 ~ 33.12 mg / L, NH 3 -N was 0.22 ~ 1.55mg / L, TN is 5.94 ~ 13.68 mg / L, TP 0.46 to 1.13 mg / L, visible carbon fiber nano- SBR process for COD, NH 3 -N, TN, TP removal efficiency is higher. In addition, the nano- carbon fiber SBR reactor shock load ability, to improve the influent COD 3 to 4 times the case , the removal rate remained at 86% ; impact load had little effect on the nitrogen , but for total phosphorus removal rate decreased greatly.
