Abstract

The invention relates to a preparation method of a polydopamine modified basalt fiber carrier and belongs to the technical field of inorganic fiber material modification and the field of wastewater treatment. The preparation method specifically includes the steps of 1), alkali etch, namely immersing a basalt fiber bundle washed with an acetone solution in a NaOH solution for etching, washing the basalt fiber bundle with deionized water for multiple times after removal, and drying the basalt fiber bundle for standby use; 2), preparation of a Tris-HCl buffer solution, namely adjusting the pH value to 8.0-8.5; 3), preparation of a dopamine modified solution, namely dissolving the dopamine modified solution and ammonium peroxydisulfate in the Tris-HCl buffer solution to obtain 2-4mg / mL of the dopamine modified solution; 4), immersing etched and dried basalt fibers in the dopamine modified solution and placing the basalt fibers on a vibrating table at room temperature, and taking out the basalt fibers for drying after vibration. The preparation method has the advantages of simple process, convenient operation and green environmental friendliness; abundant surface functional groups and good biocompatibility and hydrophilicity are achieved, the adhesive of microorganisms on the surface is promoted, the amount of film hanging is increased, and the efficiency of sewage / wastewater treatment is improved.

Description

[0001] Field [0002] The invention relates to the technical field of modification of inorganic fiber materials and the field of waste water treatment, in particular to a preparation method of polydopamine-modified basalt fiber. Background technique [0003] The biofilm method has been widely used in urban sewage / wastewater treatment. It mainly grows by microorganisms attaching to the surface of the carrier filler, the sewage is in full contact with the microorganisms, and the metabolism of the microorganisms is used to complete the removal of pollutants in the membrane. thereby purifying the sewage. [0004] In the biofilm method, the carrier filler is the habitat for microorganisms, so the performance of the carrier is the key to this treatment method, which directly affects the water purification effect. The general requirements for carrier fillers are: easy to attach microorganisms, large specific surface area, good chemical stability, no secondary pollution, cheap and ea...
