| titleOfInvention | Surface modification method of micron-sized inorganic basalt fiber carrier for sewage/wastewater treatment |
| abstract | The invention belongs to the technical field of sewage/wastewater treatment biomembrane carriers, relates to modification of micron-sized inorganic basalt fiber carriers, and particularly relates to a surface modification method of the micron-sized inorganic basalt fiber carriers for sewage/wastewater treatment. The method comprises the steps of removing a fibrinogen coating by a Soxhlet extraction method, etching by using a dilute alkali solution, soaking for 1-3 h for activation by using a 30% hydrogen peroxide solution, spraying or infiltrating by using a hydrophilic cationic solution at 20-60 ℃, and finally grafting and drying to obtain the cellulose/graphene composite material. The surface of the basalt fiber carrier is modified, so that the basalt fiber carrier material is hydrophilic and has weak positive potential, the interaction potential barrier between the carrier and microorganisms is reduced, the microorganisms are more easily attached to the surface of the carrier, the biocompatibility of the carrier is improved, the carrier is loaded with more biomass, more microorganisms are promoted to participate in the sewage/wastewater purification process, and the purification efficiency is improved. The method is simple and convenient to operate, easy to popularize, applicable to sewage/wastewater treatment and suitable for industrial production. |
