BIPHASE SEPARATING MEMBRANE, ITS PREPARING METHOD AND METHOD FOR TREATING HIGH CONCENTRATION AMMONIA NITROGEN WASTE WATER USING THE BIPHASE SEPARATING MEMBRANE

摘要

A biphase separating membrane, its preparing method and a method for treating high concentration ammonia nitrogen waste water using the biphase separating membrane are provided. The biphase separating membrane is prepared from 98-102 parts macromolecule polymeric materials, 0.001-5 parts titania fibre with 5-100 nm fibre length and 0.01-3.5 parts chemical fibre fabric according to the quality parts rate. The biphase separating membrane is prepared according to the following steps: mixing the macromolecule polymeric materials with the nano-titania fibre and the chemical fibre fabric; agitating the mixture under 160-240? and 500-3000 r/min for 0.5-8 h; drying and shaping to get the biphase separating membrane. The high concentration ammonia nitrogen waste water treatment method comprises: (1) the catalyst is added into the waste water which is then subjected to microwave irradiation; and (2) the waste water, after microwave irradiation, is flocculating settled and filtrated, and then the pH value of the waste water is adjusted to execute the biphase separation membranes treatment so as to obtain clear water.
