| abstract |
The invention discloses a sewage treatment process based on a hollow fiber membrane, which belongs to the technical field of sewage treatment. + MBR pool, disinfection equipment, discharge; wherein, at least one membrane module is arranged in the MBR pool, and the hollow fiber membrane used in the membrane module contains polyvinylidene fluoride resin, copper peptide-modified nano-TiO 2 and porogen. The hollow fiber The membrane has good hydrophilicity, water flux, anti-fouling performance, anti-compaction performance, alkali resistance, mechanical performance, interception, good photocatalytic degradation of refractory organic pollutants, and good resistance to copper ions. Has better adsorption. Therefore, the sewage treatment process of the present invention can realize the effective treatment of sewage, and the effluent satisfies the discharge standard of surface V class specified in "Surface Water Environmental Quality Standard" GB3838-2002. |
