Spadework On Application Of SiO₂ Mesoporous And γ-Al₂O₃ Nanofiltration Membrane To Decontaminate Organic Wastewater

The mesoporous membrane of SiO₂ and Al₂O₃ were prepared using self-adjustable method. It proved that self-adjustable method can prevent the crack of the inorganic membrane effectively and intellectively, moreover, the pore distribution of the membrane can be controlled easily and the technics of the preparation is very simple. The mesoporous SiO₂ membrane can dispose the wastewater of antibiotic, it has been proved that it is not only the separate effect, but also the catalysis effect. And according to the result of the experiment, the effect of catalysis was different from pressure and the pH scale, when the pressure was 0.25-0.3 MPa and pH value was under 7, it can be best effect. The treatment effect of the y— Al₂O₃ membrane was increase with the pressure goes higher.Fouling is an important problem for inorganic membrane for its using on industry. There have been many empiristic formula, but there is no one can be used in every time and each circumstance, so we set up new math model in the basic of effective proportion, this model can describe the...
