Description
Technical field
The utility model relates to sewage treatment area, and particularly a kind of bacteria filter device taking porous ceramic grain as filter packing, is mainly used in rapid diafiltration sewage treating system.
Background technology
Along with the high speed development of Chinese national economy, the quantity discharged of industrial sewage, sanitary sewage increases year by year, and meanwhile, the industry of Global Greenhouse Effect and high speed development, is reducing year by year water purification resource and be subject to pollution threat.Sewage disposal industry is faced with huge challenge and pressure, and the unique channel that solves this extremely urgent problem is exactly development of new, efficient, energy-conservation, the dirty water decontamination handles technology cheaply.
Rapid diafiltration sewage treating system (RI) is the one of polluted water land treatment technology.It selects the natural sand soil of good penetrability as oozing soon place, pond, and sewage cloth is being oozed on pond soon, and sewage, oozing soon the waterflooding and fall dryly of mutually hocketing in pond, produces complicated physics, chemistry and biological action sewage is purified by oozing soil layer under sewage.The advantage of RI system is: running expense is low, easy to operate, manageable, and effluent quality is better than conventional activated sludge process B-grade sewage treatment system.But RI also has, floor space is large, site condition requires the defects such as strict, hydraulic load is low, and ground promotion and application are only suitable for suiting measures to local conditions.
Summary of the invention
For solving many defects of RI system, the utility model provides that a kind of floor space is little, hydraulic load large, good filtration effect, cost are low, bacteria filter device taking porous ceramic grain as filter packing.
Concrete technical scheme is as follows:
A kind of porous ceramic grain biological filter is separated into the biofiltration chamber on upper strata and the collection filter chamber of lower floor with the flase floor that leaks in the body of antiseepage pond; The top in described biofiltration chamber is provided with water-in, is provided with porous ceramic grain filtering layer in biofiltration chamber; Described porous ceramic grain filtering layer is made up of porous ceramic grain that can suspend in water, the grand pore structure of surface arrangement; In described collection filter chamber, be provided with water outlet and mud discharging mouth.
Described porous ceramic grain is according to the described method preparation of formerly patent application " a kind of porous ceramic grain and preparation method thereof (number of patent application: 201310545843.5) ".Porous ceramic grain used is to utilize the solid waste such as ceramic polished waste residue, mud, coal gangue to fire to form, and lower cost for material, production technique are simple, greatly reduce material cost.Porous ceramic grain can bulk shipment, and working-yard integration packaging, reduces packaging, transport and construction cost greatly.
Sewage enters from water-in, and after the biofiltration of porous ceramic grain filtering layer, mud and filtered water flow to collection filter chamber through the flase floor that leaks, and filtered water is discharged from water outlet, and mud is discharged from mud discharging mouth.The vesicular structure on porous ceramic grain filtering layer surface has following effect: (1) can tackle suspended substance, makes the mud-water separation in sewage; (2) can be used as microorganism growth carrier, make microorganism growth in surface and absorb the organism in mud, reach biopurification; (3) porous ceramic grain filtering layer is lighter than water, and when pond body water level rises to a timing, just suspended dispersed is in water for porous ceramic grain, and the mud in filtering layer depart from the bottom of haydite sinks to pond, thereby reach the effect that haydite separates with mud.
Preferably, in this porous ceramic grain biological filter, also comprise washing unit, described washing unit comprises water pump, upper water distributor and lower water distributor; Described upper water distributor is all connected with water pump with lower water distributor; Described upper water distributor extends in biofiltration chamber, be placed in the top of porous ceramic grain filtering layer; Described lower water distributor extends in collection filter chamber; On described lower water distributor, be also provided with valve, prevent that filtered water from flowing backwards.Upper water distributor and lower water distributor are for forward and reverse flushing porous ceramic grain filtering layer.
Preferably, the bottom in described biofiltration chamber is also provided with blower fan; The effect of blower fan is in the time rinsing porous ceramic grain filtering layer, brings air into filter tank, stirs rinse water and washes away porous ceramic grain, makes the mud on the porous ceramic grain surface deposition that comes off; Another effect of blower fan air blast is for the aerobic biologic membrane of filter material surface provides oxygen, promotes the organic pollutant in aerobic biodegradation pond.
Preferably, described mud discharging mouth is positioned at the bottom of collection filter chamber, and the bottom of described collection filter chamber is also provided with for sedimentary clay being scraped to the Scraping device to mud discharging mouth.
Preferably, described water outlet has two, comprises pure water inlet and rinse water outlet, and two water outlets are all furnished with filter screen and valve.
Porous ceramic grain of the present utility model biological filter, adopts the porous ceramic grain of the grand pore structure of high-specific surface area to replace the filtrates such as ordinary ceramsite, quartz sand, gravel, improves widely filter tank absorption, filtration, the biomembranous function of load.Experimental result shows, the suspended substance in the adsorbable sewage of porous ceramic grain layer more than 90%, makes sewage obtain deep purifying, improves hydraulic load simultaneously, reduces the floor space in filter tank.
The vesicular structure of porous ceramic grain filtering layer, make it possess absorb polluted matter, interception solid particulate, the biomembranous function of load, also have that good physical strength, cost are low, lightweight simultaneously, easy cleaning, easily carrying, can be used for decontamination filler, bio-film colonization filler, water suction filler etc.Porous ceramic grain replaces traditional ordinary ceramsite, quartz sand, gravel, because cleaning water increases substantially, can and ooze soon pond by traditional rapid filter and unite two into one, and reduces executive cost, economizes the land resource.On the other hand, porous ceramic grain filtering layer possesses conservation benefits in flushing: due to the porous ceramic grain inside unicellular structure crisscross, that do not connect mutually that also distributes, make porous ceramic grain proportion lighter than water, in the time that volume of water reaches a certain amount of, porous ceramic grain suspend or floating water in, the impurity on top layer departs from haydite and sinks under water, thereby makes the easier cleaning and regeneration of filtering layer, and washing water quantity can significantly reduce.
