Abstract
The present invention's purpose is to use photosynthetic bacterium to handle the waste water that contains the ultrahigh concentration organism.Its treatment process comprises the sorption of photosynthetic bacterium thalline so as to protecting it, can not prey on by the prey bacterium it in porous carrier, improves the settleability of secondary endophytic bacteria body simultaneously.
Description
The invention relates to food factories waste water, wool is cleaned waste water, and the waste water etc. that contains dung urine contains the organism wastewater treatment method.
About containing organism, promptly contain the wastewater treatment method of biological oxygen demand (BIOLOGICAL OXXGEN DEMAND is designated hereinafter simply as BOD) composition, adopted activated sludge process in the past always.This method mat constitutes the microorganism of active sludge and removes BOD composition contained in the waste water with decomposition.Yet, mostly be most about 1000ppm applicable to the BOD concentration of the waste water of above-mentioned activated sludge process, can't directly use for the waste water such as food factories waste water etc. contains high density BOD composition.In addition, the excess sludge of being discharged is also burnt after dehydrating the processing, there is no other and effectively utilize means.
Recent known a kind of method that replaces above-mentioned sludge treatment that has, that is utilize treatment process (for example, special public clear 45-12631 number of Japanese patent gazette, special public clear 45-28234 number of the organic waste water of photosynthetic bacterium, special public clear 46-18670 number, special public clear 50-27668 number).Get final product the high concentrated organic wastewater of treatments B OD concentration with this method up to thousands of ppm, and but the bacterial body mat coagulating sedimentation of the secondary life of institute in treating processes is separated, and can effectively be used in fertilizer and feed etc. (special public clear 45-14091 number, special public clear 47-16772 number).
In addition, also have and find to use photosynthetic bacterium, reach the mixture process organic waste water that the specific bacterial body of symbiotic relationship is arranged with this photosynthetic bacterium, can obtain the method (special public clear 53-19673 number) of high degree cleaning action.
Yet, in above-mentioned known method, cultivate photosynthetic bacterium and symbiotic bacterium if will be in advance in aerator tank, plant, and in order to make the aeration tank liquor become advantage group (Flora) behind the photosynthetic bacterium, need 30 days to 45 days incubation period, and its overhead charges are also very high.
Moreover, as mentioned above, in the treatment of Organic Wastewater of mat photosynthetic bacterium, can effectively utilize secondary endophytic bacteria thalline, but because the block (cake) that makes secondary endophytic bacteria separate time institute's sedimentation with coagulating sedimentation need separate, dehydration, drying, and when making it become fertilizer again, in order to prevent the Dan Mihua of soil, time-consuming processing of taking a lot of work such as also need to ferment.
In addition, at BOD greater than 10, in the processing of the ultra-high concentration organic wastewater of 000ppm, its coagulative precipitation is bad, especially contains xylogen (lignin), in the wastewater treatment of tannin hard-decomposed organics such as (tannin), be difficult to remove fully chemical oxygen demand (COD) (CHEMICAL OXXMAND is designated hereinafter simply as COD), its result, the method for processing organic wastewater of mat photosynthetic bacterium, existence can only be applicable to the problem of the organic waste water of the thousands of at most ppm of BOD concentration.
Moreover, because photosynthetic bacterium also can be preyed on by the prey bacterium, for making processing efficiency be maintained at the level of regulation, in processing, must replenish photosynthetic bacterium in treatment trough in the past.
The present invention provides a kind of and adds the method for processing organic wastewater that the porous carrier that is adsorbed with the photosynthetic bacterium thalline is inhaled the work thing to organic waste water in order to solve the problem that exists in the above-mentioned known problem.
Photosynthetic bacterium used in the present invention refers to the bacterium of being cultivated with photoautotrophy or light organotrophy with luminous energy, can use in the present invention and belong to rhodospirillum (Rhodospirillum), rhodopseudomonas rhodospirillums such as (Rhodopseudomonas), bacterium (Chromatium) stains, outflow rhodospirillum chromatiums such as (Ectothiorhodospira), green living bacterium (chlorobium), the prominent green bacterium of handle green living Pseudomonas such as (Prosthecochloris), Crow good fortune (chloroflex, trade(brand)name), any bacterium also can be used during Crow Buddhist nun horse chloroflex such as (chloronema, trade(brand)names) belonged to.Particular instantiation it, can enumerate capsula Rhodopseudomonas (the little worker of Rhodopseudomonas Capsulata grinds bacterium and posts No. 879), thank to Li Shi rhodopseudomonas (Rhodopseudomonas shherrides fermentation is ground strain No. 12203), Crimson rhodospirillum (the little worker of Rhodospirillum rubrum grinds bacterium and posts No. 878), the red sulphur bacterium of wine and women-sensual pursuits (the little worker of Chromatium Vinosum grinds bacterium No. 870) etc.
The porous carrier that is used is zeolite in the present invention, perlite (pearlite), diatomite, ceramic sintered bodies etc., but from inhaling outstanding ability, be good with gac, and among gac, be good with the peat (peat moss) with complicated difference structure.
Make photosynthetic bacterium inhale work to be, porous carrier is scattered in the liquid of the photosynthetic bacterium that contains pure cultivation and gets final product in the method for porous carrier.In addition, also can in the organic waste water of process object, directly add photosynthetic bacterium and porous carrier.The blending ratio of photosynthetic bacterium and porous carrier, general volume ratio are about 1: 1 to 3: 1.
Be applicable to that waste water of the present invention is, food factories waste water, wool is cleaned waste water, contain the waste water of dung urine, organic synthesis plant effluent, oil-containing waste water etc. contain all organic waste water, applicable to the BOD composition is 10, the ultra-high concentration organic wastewater about 000ppm.
The wastewater treatment that the porous carrier of above-mentioned photosynthetic bacterial thallus is write in suction is, usually add the 0.005-0.015 volume % that the bacterial body total amount is a Total Water to above-mentioned waste water, porous carrier is about 0.002-0.008 volume %, but the addition of this porous carrier will determine according to the BOD concentration of waste water certainly.In above-mentioned wastewater treatment, can make milk-acid bacteria, yeast, yeast, (Saccharomyces), the white bacterium of thin,tough silk (Candida), aspergillus tubigensis (Aspergillus), rhizopus (Rhizopus) etc. with the photosynthetic bacterium symbiosis, also can coexist with the bacterium that can improve cleaning action in addition.
Be added with inhale the work above-mentioned photosynthetic bacterium body porous carrier waste water in the open or the dark place under the condition of good gas, handle it.Then, after processing with this porous carrier with bacterial body, to filter, methods such as centrifugation are captured, the words that need are dehydrated etc. again.Above-mentioned gleanings is to soil improvement agent, and fertilizer etc. are especially effective.
Make the photosynthetic bacterium body inhale work when porous carrier, this bacterial body promptly enters in the hole of this porous carrier.For example, the interstitial hole of peat (Peat moss) for having gross porosity (macro), becoming by the gross porosity difference, and by interstitial hole again difference be the hole of the complicated apparatus derivatorius of micropore (micro), but the size of this bacterial body is the 0.1-1 micron, therefore can enter in the peat below 20 microns within the hole depth place.Because the size of the predator bacteria of predation photosynthetic bacterium is the 20-200 micron; therefore can't enter the photosynthetic bacterium body state below 20 microns on existing within the hole depth place; therefore; this bacterial body is protected and is not subjected to the predation of predator bacteria, is inhaled the organism that work enters in the hole by porous carrier and then effectively and promptly is decomposed.
Again, broken away from rapid the decomposition by this bacterial body as mentioned above owing to inhaling the organism of work in porous carrier, therefore, but the suction of this porous carrier work ability long term maintenance.Moreover, can have decolorization simultaneously with gac as porous carrier, be not only the BOD composition, the COD composition also can reduce simultaneously.
In addition,, the molten amount of oxygen of depositing in the treatment liq can be improved, therefore, aeration rate can be cut down treatment liq because the hole of porous carrier contains air (gac is about 20%).
Moreover, because the core when porous carrier becomes coagulative precipitation, thereby can quicken settling velocity, at BOD 10, also can carry out settlement separate in the ultra-high concentration organic wastewater more than the 000ppm smoothly, and can reduce the volume of coagulative precipitation groove, can cut down simultaneously the addition (in the past 1/3) of flocculation agent in a large number.As a result, big with viscosity, become lonely property and make known capture thing that bacterial body dies relatively, the viscosity of the capture thing among the present invention is extremely low and be gas, thereby bacterial body is real state in the hole of porous support.
Therefore, when using this kind capture thing as soil improvement agent and fertilizer, because porous carrier can encourage the crumb structure of soil, therefore, have the raising air permeability, water conservation branch property is protected the fertilizer ability, reaches advantages such as shock absorption.Then, the digestion of the hydrogen sulfide of mat photosynthetic bacterium can stop the farmland aging.And contained volume protein in the bacterial body, amino acid, nucleic acid, red and green pigment etc. then becomes nutrition source or the growth factor of plant.
