Abstract

The invention discloses a preparation method of a multifunctional water treatment ceramisite filter material, and belongs to the field of environmental purification functional materials. The preparation method comprises the following technological steps: putting ceramisite into a hydrochloric acid solution with the concentration of 0.5 mol / L, carrying out constant temperature treatment on the solution and reaming ceramisites; preparing a titanium alkoxide and ceramisite mixture from ethanol, n-propanol, tetrabutyl titanate, glycerol and the ceramsites; adding a copper chloride aqueous solutionwith the solution of 0.3 mol / L into the titanium alkoxide and ceramisite mixture, stirring and filtering to obtain biofilm culturing ceramisites; drying the biofilm culturing ceramisites at 80 DEG Cfor 24 hours, calcining at the calcining temperature of 620 to 870 DEG C for 3 hours and naturally cooling to obtain the multifunctional water treatment ceramisite filter material. The filter materialcan utilize adsorption and biodegradation to purify sewage and also has self-cleaning ability under illumination, so that the multifunctional water treatment ceramisite filter material is suitable for water pollution treatment process with various forms.

Description

technical field [0001] The invention belongs to the field of environmental purification functional materials, and in particular relates to a preparation method of multifunctional water treatment ceramsite filter material. Background technique [0002] Ceramsite is a lightweight aggregate produced by foaming in a rotary kiln. It has a spherical shape, a smooth and hard surface, and a honeycomb-like interior. The density of ceramsite is small, the thermal conductivity is low, and the strength is high. The bulk density of ceramsite itself is generally 300-900kg / m 3 . The appearance of ceramsite is hard, and the interior is rich in micropores, which makes ceramsite light in weight. Because of these excellent properties, ceramsite has been widely used in environmental protection, building materials, gardening, food and beverage, refractory insulation materials, chemical industry, petroleum and other fields. Bio-ceramic filter material can be used as bio-film carrier of bio-fil...
