Description

Anerobic hydrolysis and high-performance biological filter as water treating system
Anerobic hydrolysis and high-performance biological filter as water treating system is a kind of sanitary sewage disposal and organic sewage treating system of relating to.
Anaerobic hydrolysis is that the acidication bacterium that produces in the anaerobic biological treatment anaerobic fixed film reactor is resolved into higher lipid acid, glycerine, amino acid, monose, alcohols, carbonic acid gas, ammonia, hydrogen etc. with solvability larger molecular organics in the sewage, thereby simultaneously insoluble organism is resolved into the solubility small organic molecule and make the biodegradability of improving sewage when disposing of sewage, handling for follow-up aerobe provides condition of water quality preferably.The acidication process is the fs of anaerobe water treatment procedure, and the microorganism growth breeding that participates in the acidication process is very fast, to envrionment conditions as: the requirement of temperature, pH value is also lower, is easy to realize under normal condition.But existing hydrolytic tank generally all is that employing is anaerobic mud bed, and in carrying out water treatment procedure, mud floats easily, runs off, and causes the effect instability of water treatment.
The high-performance biological filter as water treating system mainly is by the filler rate of load condensate in the biological filter in the raising system, improves the ability to sewage disposal.This water treatment system compares with active sludge water treatment system commonly used that to have energy consumption low, operational management and operation are fairly simple, system be difficult for to take place stops up and multiplies grey fly and cause the advantage of secondary pollution, so use abroad more, normally by grid, aerated grit chamber, preliminary sedimentation tank, the high-rate filter, second pond and sewage backflow pipeline and mud return line road and reflux pump are formed, and hydraulic load filter rate is generally at 10~20m 3/ m 2D.This system is under the high loading working condition, raising along with the filter rate, sewage shortened in the biological filter residence time, and the corresponding decline of treated effluent quality meeting, therefore just the recirculation water device need be set in system, utilize the water-in of the treated effluent recycling of part, with 1~2 times of water-reducible method of the backflow to sewage quantity to the high loading biological filter, reduce concentration of wastewater on the one hand, improve the hydraulic load of biological filter to improve effluent quality on the one hand.This system generally adopts oblique ripple filler or the plastic hoop or the honeycomb padding of price comparison costliness, need to be provided with preliminary sedimentation tank and reflux again, make that the cost of erection and the working cost of system are higher, though adopt the effect that guarantees water treatment by the method that refluxes, but, when environment is in low temperature (as winter), the efficient of sewage disposal still can reduce, and influences the effect of water treatment.
In order further to improve efficient to sanitary sewage and organic sewage processing, the invention provides and do not establish preliminary sedimentation tank and reflux in a kind of water treatment system, adopt the multiple-hearth anaerobic fixed film reactor, sewage is carried out acidication processing back cloth people earlier in anaerobic fixed film reactor adopt specific surface area big, the voidage height, handle in the biological filter that inexpensive spandex fiber filler is filled, discharge through second pond, water treatment process and management are simple, systematic running cost, the anaerobism that energy consumption and fabrication cost are all low-hydrolysis high-performance biological filter as water treating system.
Water treatment system of the present invention is by grid, aerated grit chamber, and anaerobic fixed film reactor, water-distributing device and elastic filler biological filter and second pond are formed.Sanitary sewage or organic sewage are through grid, entering anaerobic fixed film reactor behind the aerated grit chamber stopped 3~4 hours, in anaerobic fixed film reactor the acidication of sewage being handled the solvability larger molecular organics that makes in the sewage decomposes, insoluble organism is resolved into the solubility small organic molecule, improve the biodegradability of sewage.Be distributed into the elastic filler biological filter by water-distributing device then and handle, the filter tank water outlet is discharged through behind the second pond.The bottom of anaerobic fixed film reactor is provided with the anaerobic sludge layer, lays resilient filler layer at an upper portion thereof, becomes the combined anaerobic bed.The top of elastic filler biological filter is as resilient filler layer, and the bottom is as ventilating and water-yielding stratum.Elastic filler is square by polypropylene or polyethylene rope with section, the polypropylene spandex fiber silk of surface indentation is integral and becomes the elastic filler of column hairbrush shape through wringing, be laid on the interior anaerobic sludge of anaerobic fixed film reactor and in the biological filter, the laying of elastic filler highly is higher than design height in the biological filter, make elastic filler in secular operational process, still can reach the requirement of design height after sinking because of the load-bearing generation is a small amount of.
The advantage of water treatment system of the present invention is clearly, compares with the conventional activated sludge process water treatment system, builds water treatment system dissimilar and that require, and its construction cost only is 75%~85%, and energy consumption is 40%~60%.The fiber yarn of elastic filler adopts the square-section, fiber yarn surface indentation, be beneficial to adhering to and growing of microorganism, and has a good performance of anti-blockage, the fiber yarn of elastic filler intermeshes together, spill the sewage of cloth by water-distributing device, be distributed to each place in the biological filter equably, have good secondary distribution performance by fiber yarn to packing layer.Elastic filler is arranged on the interior anaerobic sludge layer of anaerobic fixed film reactor, can effectively stop the loss of mud, make the water treatment effect have satisfactory stability again, through having improved the biodegradability of sewage behind the acidication, again through elastic filler biological filter and second pond treat effluent, the total clearance of SS reaches>and 90%, BOD 5Clearance reaches 90%~95%.The whole water treatment procedure of system of the present invention is simple, manages more convenient.
Accompanying drawing is a water treatment system embodiment synoptic diagram of the present invention, wherein:
Fig. 1. be water treatment system synoptic diagram of the present invention,
Fig. 2. be anaerobic fixed film reactor structural representation of the present invention.
Now in conjunction with the accompanying drawings the present invention is further described.
Water treatment system of the present invention is by grid, aerated grit chamber, and anaerobic fixed film reactor, elastic filler biological filter and second pond are formed.Bottom in the anaerobic fixed film reactor is anaerobic mud bed 2, elastic filler bed 1 is set on anaerobic mud bed 2 constitutes the composite anaerobic bed.Upper strata in the elastic filler biological filter is a packing layer, and lower floor is the ventilation water-yielding stratum, is provided with water-distributing device on top, packing layer top.Column hairbrush shape filler is adopted in elastic filler, and the diameter of section of filler is 100mm.Sewage enters anaerobic fixed film reactor and handles through grid behind the aerated grit chamber, be distributed into the elastic filler biological filter by water distribution pipe then and handle, and the hydraulic load in the filter tank reaches 30m 3/ m 2D.The water outlet of biological filter is discharged behind second pond.The BOD of whole water treatment system 5Total clearance reaches more than 90%, clearance>90% that SS is total.
