Abstract
The invention relates to a biological filter material by utilizing sugar mill mud and a method; solid waste sugar mill mud and waste ceramics are used as main raw materials, binder clay and pore-forming agents and the like are added to prepare the biological filter material; the raw materials forms finished products by crushing, batching, ball-milling, sieving, forming, drying, sintering and cooling and other procedures; sawdust, leaves, fiber and the like can be used as the pore-forming agents for preparing the biological filter material; after the pore-forming agents and the powdery raw materials are mixed and formed, the pore-forming agents are distributed in a blank body disorderly, so as to form holes which are run-through in a three-dimensional space after being sintered. The porous biological filter material produced by the invention has high intensity, large porosity, large specific surface area and good chemical stability and can be used for sewage treatment.
Description
Technical field
The present invention relates to a kind of manufacture method of the porous ceramic film material that is used to dispose of sewage, particularly biofilter material.
Background technology
The raising that water supply quality is required along with the mankind and the increase of service discharge, and to the improving constantly of sewage drainage standard, development research has gone out various water treatment filter materials, comprises quartz sand, hard coal, polystyrene spherolite etc.Because this class filtrate partly exists inherent defects such as cost height or specific surface area be little, impels the investigator to continually develop novel filtrate and replaces.Because the material of haydite is cheap and easy to get, and has advantages such as lightweight, porous, easy to be filmed and good biocompatibility, is the research emphasis of present biofilter material.The inner porous of ceramic grain filter, specific surface area is bigger, and chemistry and Heat stability is good have absorption property preferably, are easy to regeneration and are convenient to recycling.
Summary of the invention
The present invention is to be main raw material with industrial residue sugar filter mud, waste ceramic, is binding agent with the clay, adds pore former, produces biofilter material, and a kind of preparation method of above-mentioned biofilter material is provided.
The present invention for achieving the above object, the technical scheme that is adopted is: a kind of biofilter material is provided, and it contains following component,
Sugar filter mud: 30～35%
Waste ceramic: 15～20%
Clay: 40～45%
Pore former: 5～10%
Biofilter material one optimal technical scheme according to the sugared filter mud manufacturing of utilization of the present invention: the technology of preparation biofilter material is:
(1), sugared filter mud is carried out airing, waste ceramic is pulverized.
(2), prepare burden according to the above ratio, ball milling sieves, and makes it satisfy granularity requirements.
(3), through mould molding, drying is burnt till, the cooling.
Biofilter material one optimal technical scheme according to the sugared filter mud manufacturing of utilization of the present invention: preparation biofilter material technology, drying temperature is 105～110 ℃, and sintering temperature is 950～1050 ℃, and soaking time is 30-60 minute.
Beneficial effect of the present invention is:
1, its main crystalline phase of biofilter material constructed in accordance is lime feldspar and mullite, and the formation of lime feldspar and mullite has improved the intensity of biofilter material.
The pore size distribution of the biofiltration material that 2, burns till is at 1～5 μ m, and hole is many and connect mutually, and specific surface area is big, helps the adsorption of surface electrostatic effect and micropore, can be used as good biofiltration material.
