Description
Technical field
The present invention relates to a kind of functional biomembrane carrier and preparation method and purposes.
Background technology
Along with the continuous increase of the high speed development and the population of modern industry, water pollution problems is more and more serious is threatening existent environment of people, is restricting society and economic further developing.Therefore, the protection water resources is avoided polluting has become the problem of attracting attention in the whole world.In the present wastewater processing technology that develops, biological effluent treatment has become countries in the world and has handled the main means that waste water control water pollutes.
To be waste water contact with microbial film on anchoring at carrier in the biomembrance process wastewater treatment, carries out the exchange of substance of solid, liquid phase, utilizes in the film microorganism that contaminant degradation is purified liquid waste, simultaneously, and constantly growth and breeding of microorganism in the microbial film.Therefore, biofilm carrier is the core that guarantees the efficient and economical operation of biofilm reactor, it not only provides the place of microorganic adhesion, and affect biomembranous growth, come off, form and space structure, the operating performance and the energy consumption of device had crucial influence.The size of solid support material, shape, porousness and specific surface area have very big influence to biomembranous set, formation and maturation.
The carrier of biomembrance process wastewater treatment should have good one's own rerum natura, and chemical stability, carrier surface is coarse, specific surface area is big, pore size distribution is reasonable, can strengthen diffusion and mass transfer process.Till biofilm carrier is used in the wastewater treatment now the earliest, biofilm carrier has passed through the development of eight more than ten years, has developed, developed mineral-type and organic class carrier of all kinds, various materials, has obtained the progress that attracts people's attention.At present, the biofilm carrier material of broad research and application roughly can be divided into two classes, i.e. mineral-type carrier and organic class carrier.The mineral-type carrier, major part is a bead-type substrate, as quartz sand, glass pellet, slag, gac, haydite etc., have that physical strength is big, good biocompatibility, be difficult for, thereby be the important solid support material of a class by microbiological degradation, acid and alkali-resistance, characteristic such as cost is low, the life-span is long.Inorganic carrier has vesicular structure mostly, utilizes adsorption and electrocharge effect that microorganism is fixed when contacting with microorganism.There is bigger porosity inorganic carrier inside, can hold the microorganism of continuous propagation, makes carrier inner cell concentration increase.Organic class carrier mainly can be divided into two big classes: a class is the chemosynthesis macromolecular material, as polymer plastics such as polyethylene, polystyrene, polypropylene, thermovyl, polyurethane foams; Another kind of is natural macromolecular material, and this type of material is generally good to biological nontoxic, mass-transfer performance, but physical strength is lower, and easily by microbiological degradation, the life-span is short.Common examples of such carriers has agar, carrageenin, Na-alginate etc.
Make a general survey of the research of biological treatment carrier and use present situation, the special emphasis of carrier exploitation at present mainly concentrates on the physicals aspect of carrier, the biofilm carrier of current widespread use has exposed a lot of deficiencies at aspects such as biocompatibility, stability, mechanical property, biofilm speed and manipulation of regeneration, has restricted the development of biomembrance process water technology.The biofilm carrier of using in view of present broad research mostly is a bio-inert material, and the good environment of microorganism growth can not initiatively be provided, and biofilm speed is slow; Therefore research and development have the grow functional biomembrane carrier of required microenvironment of regulating and controlling microbial initiatively and have represented the new direction of bio-carrier development, for the biofilm speed that improves carrier and the efficient of reactor, develop efficient, practical water conditioning facility and have great significance.
Summary of the invention
The purpose of this invention is to provide a kind of functional biomembrane carrier and preparation method and purposes.
