Among the present invention, the agent structure of septic tank 3, elevated tank 5, straight tube settling bath 6 and micro-aerated biological filter 8 can be with utilizing material manufacturings such as cement, brick, steel, glass reinforced plastic, engineering plastics, the height of elevated tank 5 is provided with higher, the water that makes 4 liftings of process water pump enter elevated tank 5 is passing through post precipitation, and the available height difference flows into straight tube settling bath 6 automatically and micro-aerated biological filter 8 is handled.
The biomass screen plate, biomass pipe and biological-material-tall are the stalks that adopts the rural area, for example: straw, cogongrass, wheat straw, kaoliang stalk, maize straw, cotton seed hulls, Exocarpium cocois (Cocos nucifera L), rice chaff, reed, leaf, bagasse etc., these biomass are obtained Mierocrystalline cellulose through gas explosion, hemicellulose, xylogen, add special linking agent and water wetted material 5%(polyvinyl alcohol etc.) and by compound at many levels, the useless amino coating that linking agent adopts paint industry to produce, through regeneration again, the urethane first component or the second component of adding 3-5%, stir through mechanical compaction, general compacting divides two road technologies, compacting is the biomass screen plates for the first time, the inside of biomass pipe or biological-material-tall, can be more closely, keep the aperture about 1-10 microns, second road is the outsourcing type, structure can compare pine a bit, generally be controlled at 30-50 microns, through being suppressed into the filtering biological degradable material of structure tight inside but loose outside, and hydrophilic coating adopts polyvinyl alcohol, according to the same xylogen of 5% the aqueous solution, useless coating mixes simultaneously, disposable compacting, biomass screen plate after the compacting, biomass pipe or biological-material-tall, be placed on the place 36 hours of circulation of air ratio, make it dry, perhaps be placed under the sunlight and be exposed to the sun 8 hours, make internal crosslinking agent, the hydrophilic group drying.60 millimeters of the diameters of biomass pipe, high 800 millimeters, the diameter of biological-material-tall is between 30～50 millimeters.Biomass screen plate, biomass pipe and biological-material-tall mainly come organism, ammonia nitrogen, SS in the degradation water etc. by microorganism when disposing of sewage, reach filtering purpose simultaneously.
Principle of work of the present invention and working process:
The present invention handles sanitary sewage, at first consider the various compositions that sanitary sewage contains, for example school, hotel, cooking, catering trade major ingredients are: ight soil, animal skin, spur, toilet paper, silt, vegetables, grain, really, shell, plastic paper, seasonings, karyomit(e), washing composition etc.; Mainly hair, washing composition, scurf etc. in the bathing pool.All living miscellaneous wastewater principal pollutant are that organism, ammonia nitrogen, phosphorus (washing composition) are main.Treating processes: sewage at first passes through coarse rack 1, enter fine fack 2 then, coarse rack 1 and fine fack 2 main solid matter and the hairs of removing greater than 15 microns, handle later sewage and enter septic tank 3, at settling bath 301 precipitation silt class solid particulates, in foam groove 302, remove the oil that suspends in oil removal, foam, said structure is equivalent to the septic tank in rural area, sewage is anaerobic treatment and sedimentary effect therein, then after biomass screen plate 305 filtrations through first filter vat 303 and second filter vat, 304 sidewalls, enter in second filter vat 304, sewage rises in the elevated tank 5 with water pump 4 then, utilize the drop pressure of elevated tank 5 to make sewage enter straight tube settling bath 6, straight tube filter core 7 in the straight tube settling bath 6 can with mao bamboon manage 701 and biomass pipe 702 form, fixing with wire netting 703 up and down, mao bamboon pipe 701 must be removed the peel, go joint inside and outside smooth, be convenient to the microorganism growth breeding, form bacterial mass, 50-60 millimeters of straight tube precipitation barrel diameters, 500-600 millimeters of length, sewage moves up from straight tube filter core 7 bottoms, produce frictional force, make small-particle rapid cohesion being transformed into macrobead be deposited to bottom of device rapidly and efflux oil, floating matters such as foam cohesion come-up also effluxes.
Sewage is gone into micro-aerated biological filter 8 through straight tube settling bath 6 is laggard, water progressively flow through first biomass groove 802, the second biomass groove 803 and the 3rd biomass groove 804, water each biomass groove of from bottom to top flowing through, and two pairs of little aeration heads 10 are all installed in each biomass groove bottom, are equivalent to that sewage has been carried out three little aeration and biological methods and handle.
The little aeration and biological method of micro-aerated biological filter 8 usefulness is handled sewage, and its hydrolysis process mechanism is as follows:
Biochemical processing method in the sewage treatment process is a main method of handling organic waste water, hydrolysis process is meant complicated organic molecule, in addition water molecules is decomposed into the reaction of simple compounds under lytic enzyme participates in, wherein the catalyzed reaction efficient of enzyme is higher 106～1013 times than corresponding no enzyme reaction, and above-mentioned reaction is carried out under anoxia condition.The difference of hydrolysis process and anaerobic technique: anaerobic reaction divides four-stage: hydrolysis, acidifying, acidifying decline and methanation, at hydrolysis stage, solid matter is converted into dissolved matter, macromolecular substance is degraded to small-molecule substance, and the difficult for biological degradation goods and materials are converted into easy degradable chemical, at souring stage, organic matter degradation is various organic acids, hydrolysis and product acid are carried out comparatively fast, and difficulty is separated them, and the major microorganisms that works is hydrolysis bacterium and sour bacterium.So-called hydrolysis process, preceding two sections of utilizing anaerobic technique exactly promptly are controlled at reaction before the subordinate phase, do not enter the phase III.Be the difference anaerobic technique, name and be hydrolysis process, in hydrolysis reactor, in fact finish " hydrolysis " and " acidifying " two processes.Abbreviate " hydrolysis " as.If microbial host aerobic-anaerobic microbe in the hydrolysis process system, they are more in occurring in nature quantity, reproduction speed is fast, and methane-producing bacteria then is strict obligatory anaerobic bacteria in the anaerobism, and they are for the variation of environment, as ph value, basicity, heavy metal ion, washing composition, ammonia, the variation of sulfide and temperature etc., than hydrolysis bacterium and sour bacterium sensitivity many, and vegetative period is very slow.
Micro-aerated biological filter is the sewage treatment technique that rises at the beginning of the 90's, and is widely popular in developed countries such as American-European and Japan.This technology has the effect of removing SS, COD, BOD, nitrated, denitrogenation, dephosphorization, removal AOX (objectionable impurities), be characterized in collecting bio-oxidation and hold back suspended solids and one, saved the post precipitation pond, its volumetric loading, hydraulic load are big, hydraulic detention time is short, and required initial cost is few, and effluent quality is good, operation energy consumption is low, economic operating cost.
Treatment effect:
Water inlet: COD600～800mg/L BOD300～500mg/L oil: 1800～3600mg/L
Water outlet: COD＜50mg/L BOD＜30mg/L oil:＜5mg/L
