Abstract

This paper describes efficiency improvement in wastewater treatment to separate SS component using anaerobic fermentation with fixable microorganisms and multihole glass separation films. Measurement of microorganism deposition on microporous PVF resin in a fermentation tank revealed that hydrophilic resins with smooth surface have better deposition, and the suitable carrier hole diameters were from 300[mu]m to 500[mu]m. Adding slightly-soluble carbonate when bacteria are fixed collectively is effective in preserving the entire methane fermentation reaction system and stabilizing the carriers. A composite film comprising SiO2-ZrO2-based porous glass made by using a sol-gel process and porous ceramics had the maximum desalination rate reaching 90%. The permeation rate at a film thickness of 2[mu]m was 46 times as much of that for 500-[mu]m single-layer porous glass. As a result of reforming the pore surface by introducing -Si(CH3)3, the film has turned affinitive to non-polar solvent, repelling water to permeate. In an experiment for fermentation liquid permeation of separation film composite bioreactor using digestive sludge, the higher the SS particle concentration, the more the initial clogging was difficult to occur. The film permeating flow velocity showed a maximum value at hole diameters of about 0.2[mu]m. 3 refs., 6 figs., 2 tabs.
