Description
Technical field
The present invention relates to purifying method of a kind of contaminated fluids and uses thereof, particularly relate to and a kind ofly utilize a plurality of block fiber assemblies that move with fixed form or along with this contaminated fluids to purify the method for this contaminated fluids, in addition, also relate to a kind of contaminated fluids purification system, be applicable to the preparation method of the bio-carrier of handling this contaminated fluids and by the prepared non-woven biological carrier of this preparation method.
Background technology
The treatment process of existing contaminated fluids (as waste water or waste gas) adopts chemistry or physical treatment mode to carry out mostly, for example utilize and filter or the interpolation chemical, and along with the lifting of biotechnology, except with the existing filter type treatment of contaminated fluids, have many methods of utilizing the microbiological degradation mode to come treat fluid.Because microbial numbers and survival time are difficult to control, when reality is used, a kind of environment that is beneficial to microorganism growth can be provided mostly, and for controlling microbial quantity more advantageously, at present the mode of normal employing for the bio-carrier that is suitable for microorganism growth (biomass carrier) is provided.
Can provide the bio-carrier of microorganism growth and decomposing pollutant can be divided into embedding formula and attached type (fixed-film) two big classes.Embedding formula bio-carrier, a kind of fixation of microbial cell that for example Chinese utility model patent CN2132750Y is disclosed and the membrane carrier of enzyme, this carrier is by the mesh fabric support layer and is attached to this fabric and is embedded with microorganism cells and two gel coats of enzyme are constituted, in addition, Chinese invention patent CN 1298018A has disclosed a kind of chip coating carrier of surperficial immobilization of biological substances, its making method is: select for use insoluble material as basic core earlier, again with basic core Drug coating dressing, at last with activator with the chip coating carrier surface active after, combine with wanting the fixed biological substance again, to make this chip coating carrier.But, when making embedding formula bio-carrier, must elder generation select to cultivate specific microorganism cells, just can further it be embedded in the bio-carrier according to the characteristic of the pollutent of desire processing, thereby allow whole manufacturing cost increase and to make flow process complicated, so present less use.
The attached type bio-carrier, for example European patent EP 0433139 discloses a kind of aerobic-type biological nitration method of utilizing the biological particles bed to carry out effluent.This biological particles bed be with the carbonic ether particle as loaded particle, and on this loaded particle, adhere to nitrated microorganism and make.But the shortcoming of this patent is: when utilizing the biological particles bed as bio-carrier, in the stage of releasing, its bio-carrier particle must or filter through precipitation, and then sends the bio-carrier particle back to biological tank, so treatment scheme is comparatively complicated.Canadian Patent CA 1217581 mentions with polyurethane sponge as bio-carrier, though having bigger area, polyurethane sponge can supply microorganic adhesion, but because the hole of polyurethane sponge does not communicate each other fully, so available hole is limited, and when reality is used, this polyurethane sponge is difficult for submerged, and must the experience long time is submerged slowly, so also can influence processing efficiency.
The Taiwan patent announcement has disclosed the preparation method that a kind of embedding has the polyvinyl alcohol copolymeric foam body of active carbon powder for No. 513449, this foam can be used as bio-carrier, but its preparation method must comprise preparation prepolymer (containing the polyvinyl alcohol of 15-20 weight %, chitosan and the polyisocyanates of 1-2 weight %) earlier, again the step that will foam to this prepolymer.The bio-carrier of this patent preparation process when practical application is too complicated, can increase cost of manufacture.
Also have, the Taiwan patent announcement has disclosed waste water/water treatment method that the microorganism on the porous carrier is fixed in a kind of use No. 593168, and this porous carrier comprises foam polymer precursor and is attached to the hole internal adsorption agent particulate of this foam.And in the specific embodiments of this patent, this foam polymer precursor is a urethane, and this sorbent particles is gac, diatomite or zeolite.Because the employed carrier of this patent is the foam form, so available porosity ranges is between 30%-100%, though it has more hole, but the easy phenomenon that generation can't submerged, therefore must in this porous carrier, must carry out hydrophilic treatment in addition, just can allow the smooth submerged of this carrier.Because the production method of this porous carrier is still too numerous and diverse, limit to its range of application easily.
Numerous and diverse and can't bring into play shortcoming such as purification efficiency at the making processes of existing bio-carrier, if can be used for fluid purification and system with possessing the bio-carrier of making simply and can bringing into play advantages such as purification efficiency, can effectively improve environmental pollution problems, and for present industry, still there is great demand.
