Experimental Study Of Microfiltration As The Core Process Sanjiadian Micro-polluted Water

In this paper, microfiltration, the core processes of treatment was studied, this two processes that studied: coagulation- microfiltration and pre-oxidation microfiltration, the result showed: in aspect of removing matter in suspension, organic matter, turbidity ,which reached the goal that we have expected. Compared with parallel filter and plumb filter, the result showed the fore enhanced remarkably in holding back film to be polluted and enhanced water outcome of film. In addition, in summer ,When algae reproduce a lot, the remarkable effect for removing algae was showed in the pre-oxidation microfiltration processes. Filter precision of the film has been proved by characterize of film, is 0.2 μ m. porosity is 40.53%.In addition, UV-Fenton reagent, Advanced Oxidation Processes, was studied in this paper, the result showed: Advanced Oxidation Processes have a capable of removing organic matter, when citric acid salt was added in reactor, the removal rate of COD was remarkably enhanced , which proved that citric acid salt and Fe3+ came into being light-sensitive matter, compared with Aops and Aops+active carbon, the result showed that the later have a merit of condensing react time, reducing oxidation reagent and charge of water -treated .
