Abstract
The utility model discloses an integrated combined packing biofilter, which relates to the field of the sewage advanced treatment, and in particular to the effective improvement of the prior sand filtering process. On the premise that the removal effect on suspended substances and total phosphorous is guaranteed, the integrated combined packing biofilter can reduce the back washing resistance, eliminate the influence of the back washing on a bio-membrane, improve the removal effect of the ammonian and the total phosphorous and can realize the uniform water distribution of the sand filter. Quartz sand homogenous filter materials are uniformly filled inside straight-tube honeycomb packing which is vertically arranged inside the filter, semi-flexible packing is vertically suspended on the upper part of the straight-tube honeycomb packing through a bracket, an adhesive bio-membrane is cultured on the surface of the semi-flexible packing, and an automation control system controls the bracket to elevate freely. The integrated combined packing biofilter improves the removal effect of the ammonian and the total phosphorous, improves the quality of the water which is discharged from the filter, saves the addition quantity of a flocculating agent and the water and air consumption for back washing, has simple modification and improves the economic benefit.
Description
Technical field
The utility model relates to the advanced treatment of wastewater field, is the effective improvement to existing sand filtration technology, specifically is a kind of biological filter of adopting integrated combined stuffing.
Background technology
In sand filtration technology, but for guaranteeing that effluent quality, improvement filtering layer contain dirty ability and give full play to gas, water backwashing system effect, generally adopting with homogeneous quartz sand is the filter tank of filtrate.Find that in the actual moving process of filter tank the quartz sand homogeneous filtering material is good to suspended substance (SS), total phosphorus (TP) removal effect, but to ammonia nitrogen (NH
4-N) and total nitrogen (TN) remove limited in one's ability, thereby influenced effluent quality.
Warp is discovered prior art, in order to improve the removal effect of ammonia nitrogen and total nitrogen, can adopt biological sand filtration technology, promptly cultivates attached biological film on quartz sand homogeneous filtering material surface.But this research still is in experimental stage and not practical application as yet, because existing biological sand filtration back flushing is bigger to the microbial film influence, the microbial film that adheres to simultaneously can influence the removal effect of suspended substance, total phosphorus.
The while filter tank is in actual moving process, because the unhomogeneity of filtrate and the complicacy of coming the water water yield, water quality make existing sand filter exist water distribution inhomogeneous in the process of filtration and back flushing, thereby seriously reduce filtration efficiency.
Summary of the invention
The utility model adopts a kind of integrated combined stuffing biological filter at existing sand filtration technology deficiency.The utility model can reduce the back flushing resistance under the prerequisite of assurance to the removal effect of suspended substance, total phosphorus, eliminate back flushing to biomembranous influence, improves the removal effect of ammonia nitrogen and total nitrogen, and realizes the sand filter water distribution uniformity.
The technical scheme that its technical problem that solves the utility model adopts is: be arranged vertically straight tube honeycomb filler in sand filter, the quartz sand homogeneous filtering material evenly is packed in the straight tube honeycomb filler, it is 50% of straight tube honeycomb packed height that the quartz sand homogeneous filtering material is filled the degree of depth, support vertical hanging semi soft packing is used in the back on straight tube honeycomb filler top, it is 40% of straight tube honeycomb packed height that semi soft packing hangs the degree of depth, cultivates attached biological film on the semi soft packing surface.Come water after water distribution, evenly enter straight tube honeycomb filler inside, solved the uneven problem of water distribution, water is after the microbial film effect simultaneously, ammonia nitrogen and total nitrogen are by removal of microorganisms, and under the filteration of quartz sand homogeneous filtering material, suspended substance, total phosphorus are further removed subsequently.Automation control system control bracket free lifting, when back flushing begins, automation control system upwards promotes support, lift height is 40% of a straight tube honeycomb packed height, back flushing finishes, support is got back to former height, has eliminated back flushing and has impacted for microbial film, has saved the dosage of flocculation agent and back flushing water loss, tolerance.
The beneficial effects of the utility model are, improve ammonia nitrogen and total nitrogen removal effect, improve the filter tank effluent quality, save the dosage of flocculation agent and back flushing water loss, tolerance, transform simply, increase economic efficiency.
Description of drawings
Further specify this use is novel below in conjunction with accompanying drawing.
Fig. 1 is the sectional view of the integrated combined stuffing of the utility model biological filter.
Fig. 2 is the A-A sectional view of Fig. 1.
Among the figure: 1. straight tube honeycomb filler; 2. semi soft packing; 3. support; 4. quartz sand homogeneous filtering material; 5. supporting layer.
Embodiment
In Fig. 1, Fig. 2, be arranged vertically straight tube honeycomb filler (1) in the sand filter, quartz sand homogeneous filtering material (4) evenly is packed in the straight tube honeycomb filler (1), relatively independent honeycomb can be divided into sand filter independently small-sized separately filter tank.With support (3) vertical hanging semi soft packing (2), attached biological film is cultivated on semi soft packing (2) surface on straight tube honeycomb filler (1) top in the back, and each support (3) is parallel to each other, and support (3) is controlled by automation control system.
In Fig. 2, straight tube honeycomb filler (1) is arranged vertically on supporting layer (5), it is 50% of straight tube honeycomb filler (1) height that quartz sand homogeneous filtering material (4) is filled the degree of depth, it is 40% of straight tube honeycomb filler (1) height that semi soft packing (2) hangs the degree of depth, automation control system control bracket (3) free lifting.
In embodiment illustrated in fig. 2: in filtration procedure, automation control system control bracket (3) descends, it is 40% of straight tube honeycomb packed height that semi soft packing hangs the degree of depth, come water after water distribution, evenly enter straight tube honeycomb filler (1) inside, by the microbial film effect, filter through quartz sand homogeneous filtering material (4) again, will filter clear water at last and import discharge channel.In backwash process, automation control system control bracket (3) rises, lift height is 40% of a straight tube honeycomb packed height, utilize the souring of upstream, the impurity that is attached to filter material surface in each small-sized filter tank is washed away and suspend in water, under the effect of backwashing water, last impurity is discharged with discharge channel.
