Description
Technical field
It is vertical flow filter bed that the utility model relates to a kind of aeration reinforcing type that is used to dispose of sewage, and belongs to environment-friendly engineering and water-treatment technology field.
Background technology
Main at present source of pollution control and the ecological restoring method of adopting administered sewage, and artificial filter bed is one of important scientific method.Artificial filter bed is a kind of sewage disposal technology of continuous evolution, ultimate principle is: the specific plant of plantation on certain filler, when effluent stream is crossed artificial filter bed, filter through sandstone, soil, by the multiple microbial activities of aerobic one by one in the matrix fill layer of sand, anaerobic reaction micro unit and plant rhizosphere, the biochemical degradation precipitation reduces Pollutant levels, water quality is purified, until qualified discharge.Treating processes comprises biochemical reaction, as decomposition and anabolism, plant absorbing; Physical-chemical reaction is as precipitating absorption etc.
Utilize artificial filter bed that artificial filter bed of free-water level or the artificial filter bed of undercurrent type are adopted in the sewerage ecological reparation usually.The artificial filter bed of undercurrent type according to sewage thereon mobile direction difference more refinement be divided into horizontal flow filter bed and vertical flow filter bed two kinds.The artificial filter bed hydraulic load of free-water level is low, and sewage treating efficiency is not high, needs a large amount of waters and soil with the assurance decontamination effect improving, and in a single day the pollution of area source input is arranged, and its decontamination effect improving is very not obvious.The horizontal flow filter bed is compared with the artificial filter bed of free-water level, and hydraulic load and pollution load are big, and is good to organism such as BOD, COD and heavy metal removal effect.But the horizontal flow filter bed is compared with vertical flow filter bed, its shortcoming be denitrogenation, dephosphorization effect a little less than.
Vertical filter bed refer to sewage from the intermittent water distribution of settling tank to the filter bed surface, vertical flow by gravity downwards is a kind of high efficient technology in the artificial filter bed then, effectively handles all kinds of sewage in conjunction with physical filtering and biochemical reaction.Matrix fill in the filter bed provides a very adapt circumstance for microbial bacterial, organonitrogen is an ammonia nitrogen through the ammonification mineralising, under aerobic condition, ammonia nitrogen changes nitrate and nitrite into through nitrification, then under the condition of anaerobism and organic carbon source, partly be reduced to nitrogen through denitrification, discharge into the atmosphere.P contained compound mainly is reaction in matrix fill, enrichment, precipitation, thereby removes from sewage.In the sewage infitration process, by aerobic, the anaerobic reaction micro unit in the filler layer of sand, the biochemical degradation precipitation, Pollutant levels reduce.
The existing vertical flow filter bed square structure that is, existence assembling inconvenience, water distribution are inadequately evenly, filter bed corner water distribution is insufficient, the inner dissolved oxygen content of filter bed is low, active low, the deficiencies such as filter bed stops up easily, building structure is stable inadequately, floor area of building waste of aerobic microbiological.
The utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, provide a kind of aeration reinforcing type vertical flow filter bed, be intended to effectively solve the problem of vertical flow filter bed inconvenience assembling and have that the dead angle causes that processing is perfect inadequately, the inner dissolved oxygen content of filter bed is low, active low, the wetland of aerobic microbiological problem such as obstruction easily.
The purpose of this utility model is achieved through the following technical solutions:
The aeration reinforcing type is vertical flow filter bed, characteristics are: described filter bed is the circular configuration that two semicircles constitute, the filter bed bottom is equipped with anti seepage membrane, be covered with header on the described anti seepage membrane, described header two ends connect ventpipe, in the described header micropore aeration pipe are installed, and micropore aeration pipe is connected to aeration and is responsible for, aeration is responsible for and is connected to gas blower, and tail-hood is installed in the header left and right sides; The inner filling substrate of described filter bed, filter bed surface serike; Two semicircle upper edge filter bed diametric(al)s at filter bed are distributed with the water distribution person in charge respectively, are responsible for the water distribution branch pipe that is connected with water distribution and are arranged to external irradiation by the filter bed center with semicircle shape.
Further, above-mentioned aeration reinforcing type is vertical flow filter bed, and described matrix is made of ecological filler processing layer, transition layer and layer of displacement, and described ecological filler processing layer is the upper strata, and described transition layer is the middle layer, and described layer of displacement is a lower floor.
Further, above-mentioned aeration reinforcing type is vertical flow filter bed, is disposed with gravel bed and lime compacting bed course between described filter bed bottom and the anti seepage membrane.
Again further, above-mentioned aeration reinforcing type is vertical flow filter bed, and described header is arranged to external irradiation with the filter bed center, and header connects ventpipe near filter bed body of wall one end.
Technical solutions of the utility model substantive distinguishing features and progressive being mainly reflected in:
The circular vertical flow filter bed structure of the vertical flow filter bed employing of the utility model aeration reinforcing type, micropore aeration pipe is set up in header inside, increase the conveying of the inner oxygen of filter bed, purpose is airborne oxygen is dissolved in the water, perhaps unwanted gas and volatile matter in the water are banished in the air, thereby the active and biochemical reaction intensity of aerobic microbiological improves the clearance of organic pollutant and nitrogen in the enhancing filter bed, and prevents that effectively filter bed from stopping up.The used hypothallus filtrate of artificial swamp is determined by two step experimental techniques of Glan spy (Grant) filtrate permeability test and size analysis, selects to satisfy the filtrate of specific graduation curve, guarantees artificial swamp operation steady in a long-term, the denitrogenation dephosphorizing effect stability.This facility is applicable to the processing of domestic sewage in rural areas by using, urban landscape water and lake sewage etc., has that processing efficiency height, landscape effect are good, resources conservation, flexible operation, characteristics such as applied widely.
