In the utility model, principle of work of each equipment and uses thereof is:
1, grille well: sanitary sewage enters grille well through conduit, and grid is set in the grille well, tackles suspended substance larger in the sewage or floating matter such as wood chip, paper scrap, plastics etc., prevents follow-up equipment, line clogging.And play the energy-storage function of pulse water distributing device.
2, pulse water distributing device: the water inlet distribution system is vital to the good operation of sewage disposal device, and is low
The water level pulse water distributor, it partly is comprised of surge generator, water-distributing device etc., be characterized in the low situation of water inlet head, need not consuming extra power, storage hydraulic potential, moment draining, to the periodically large flow pulse water inlet of hydrolysis acidification pool, stir active sludge at the bottom of the pond make its with the pond in sewage constantly stir and mix, microorganism, facultative anaerobe etc. are fully contacted with organism in the sewage, improve significantly the processing efficiency of hydrolysis acidification pool.
3, hydrolysis acidification pool: hydrolysis acidification pool is formed the recurrent pulses water inlet through pulse water distributor water inlet distribution system, add spherical suspending filling material in the hydrolysis acidification pool, bed of packings and Sludge Bed that hydrolysis acidification pool forms, synergy by facultative anaerobes such as hydrolysis bacterium and acid-producing bacterias, the degraded partial organic substances, and insoluble organism is converted into soluble organism, and the macromolecular substance of difficult degradation is converted into the small-molecule substance of easy degraded, improved the biodegradability of sewage; Be provided with hydraulic potential in the described pulling flow type hydrolysis acidification pool and discharge water distributor, intake by the pulse water distributing device recurrent pulses, hydraulic potential is released into the vertically progressively extremely outlet of plug-flow that fluctuating flow is prolonging the pond, microorganism on the microbial film is mixed fully with organism in the sewage, fluctuating flow impacts bed of packings simultaneously, makes downright bad biofilm detachment on the filler, has created good condition for forming new microbial film.After the accumulation of mud through certain hour (about a year), excess sludge is cleared up, is transported outward in the pond.The hydrolysis acidification pool water outlet promotes (or flow by gravity) to the tower biological filter by sump pump.
4, tower biological filter: the biological filter is comprised of body of the tower, filler, water-distributing device, ventilation system, captation etc., and water outlet and the settling bowl of captation link.It is a kind of efficient biological treating equipment, can the amount of disposing of sewage be about about 10 times of packing volume every day.Its water purification ability is every cubic metre of filler 1 ~ 3kg biological oxygen demand every day, is 10 ~ 20 times of ordinary biofilter.The clearance of BOD5 can reach 60 ~ 80%.
Load light weight in the tower biological filter, large and the high filler of porosity of specific surface area, sewage is spread in filter material surface equably by water distributor, sewage relies on the action of gravity filler of flowing through from top to bottom to form water membrane, and the tower biological filter is provided with ventilation system, air passes through filler from bottom to top by the natural wind turning effect of tower body, air fully contacts with microbial film three-phase on being attached to filler, when sewage passes through the filter tank, filler has been held back the suspended substance in the sewage, while is adsorbed on the colloid in the sewage and dissolved matter on the surface of oneself, organism wherein makes the very fast breeding of microorganism get up to have formed microbial film, and these microorganisms have further been adsorbed again and have been suspension in the sewage, the organism of colloid or solubilised state.
The needed oxygen of microorganism growth is from the sewage, constantly replenish the dissolved oxygen that loses, mass transfer velocity and biomembranous renewal speed have been accelerated, improved the organic loading that the unit volume filler is born, thereby made sewage obtain desirable decontamination effect improving, simultaneously because the souring of sewage, aging microbial film constantly comes off, new microbial film is constantly growth again, and the microbial film that comes off flows out the filter tank with current, carries out moisture film to settling bowl and separates.
The characteristics of tower biological filter are that operation is simple, aerator that need not conventional biological contact oxidation filter tank, management, safeguard simple, working cost is low, it not only can move under High Load Rate, and the ability to bear that the influent quality water yield is changed is stronger, the microbial film that comes off is closely knit, is easier in settling bowl separated.
5, settling bowl: most of organism is removed in the sewage that process the tower biological filter, for further improving clearance, the nitrogen dephosphorization is particularly fallen, the biofiltration settling bowl is set, formed by settling region and bacteria bed, adopt flow lifting type Inlet and outlet water mode, filter bed filter material adopts light filler, light filler is comprised of spherical suspending filling material and lightweight biologic packing material, it integrates bio-oxidation and holds back suspended solids, and the tower biological filter water outlet is through the biofiltration settling bowl, and the microbial film that comes off in the water is removed, water pollutant is further degraded and is filtered final qualified discharge, and the bottom of settling bowl is used for sedimentation mud.
The above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
