Abstract
The technology of treating sewage with ecologically active filler belongs to the field of improved biofiltering technology. The present invention includes underground reinforced concrete structure, ecological greening, and natural active filler of shell and other solid waste capable of attaching microbes and stimulating the activity of microbes to eliminate organic matter from sewage. The biofilter with both aerobic region and anaerobic region has the functions nitrating, denitrifying and dephosphorizing to eliminate pollutant from sewage effectively, and is suitable for treating city sewage, river sewage and industrial effluent.
Description
Technical field
The invention belongs to technical field of sewage, being specifically related to a kind of is the natural, ecological dirty water living creature processing technique of active filler with oyster shell, pearl shell.
Background technology
The bacteria bed technology is used for the purifying treatment of municipal effluent, river course combined sewage and industrial sewage, is a kind of common and effective sewage disposal technology.And the key of bacteria bed technology is exactly a filler selection.Currently used filler mainly contains natural process material and synthetic materials such as polyethylene, acrylic plastering such as quartz sand, rubble, cobble, hard coal, coke, gac, haydite.The natural process material source is extensive, but poor, the unfavorable microbial growth of biofilm is therefore not obvious for wastewater purifying efficiency.And synthetic material has generally added biological promotor, is beneficial to the apposition growth of microorganism, but can produce secondary pollution in its production process, and because its price height is difficult to scale operation, therefore is difficult for promoting.
Summary of the invention
The present invention system is to the improvement of bacteria bed technology, main innovation is utilization of waste material, introduced the filler of a kind of novel natural, ecological material as bacteria bed, this filler is made up of oyster shell and pearl shell, and bacteria bed is placed underground, surface coverage plantation plant reaches pollution treatment and greening dual purpose.The technology of the present invention is mainly used in the cross biopurification of sewage and industrial sewage of municipal effluent, river course combined sewage, the river mouth degree of saltiness and handles.
Main gordian technique of the present invention is with the microbial film of oyster shell, the pearl shell surface attachment treatment media as sewage, both abundant metabolism of microorganism, to the removal of degrading of the organism in the sewage, and owing to exist aerobic and anoxic zones in the filter bed, can realize nitrated, denitrification and phosphorus removal functional synchronously, when sewage by suspended thing, colloidal are filtered, adsorb, reach effect to organic removal and denitrogenation dephosphorizing.Shell particle after employing is pulverized can further improve the effluent quality standard as filtrate.
Principal feature of the present invention is presented as " nature ", " ecology ", " efficiently ".
" nature ": oyster shell, pearl shell originally are the solid waste in city, if can not timely and effectively carry out treatment and disposal to it, will produce very big influence to the The Surroundings in Cities health.The present invention can be the disposal of shell refuses such as oyster shell, pearl shell and finds an effective outlet;
" ecology ": in the technology of the present invention, the bacteria bed surface is covered by soil property, and plants and go up all kinds of plants, both can reduce the negative impact to surrounding enviroment, can reach good ecoscape effect again;
" efficiently ": the oyster shell, pearl shell is former is the medium of biological growth, contain abundant chitosan, microorganism there are very strong crystallized ability and avidity, it is a kind of natural radioactivity filler, after the certain processing of direct or do, biological promotor be need not add, microbial growth implantation and stimulating organism activity but are easy to, its surface biological film has powerful metabolism, thus the organism effectively in the degradation of sewage; Oyster shell, pearl shell are to form in the ocean, are fit to the apposition growth of halophilism microorganism, therefore, cross in the river mouth degree of saltiness in the salt environment such as sewage, saline sewage, also can effectively bring into play microbial film to organic degradation function; Oyster shell, pearl shell surface irregularity porous form different aerobic and anoxic zones easily in filter bed, help the nitrification and denitrification of sewage, and the main component of housing itself is calcium, magnesium salts, helps dephosphorization.
In addition, the dirty water living creature processing technique of natural way of the present invention on filler selection, than the filler that generally adopts at present, has wide material sources, the little advantage of investment, more helps demonstration and promotes.
Embodiment
The present invention system is to the improvement of bacteria bed technology, so the pre-treatment of sewage, the design of filter bed, the back flushing in filter tank and the design of follow-up structures belong to known technology.
Concrete embodiment:
To certain river sewage, adopt treatment technology of the present invention, processing power is 1000m
3/ d, processing technological flow is " sewage → grid → lifting → natural, ecological treatment system → discharging ", recommended flowsheet is " sewage → thick, fine fack → lifting → natural, ecological treatment system (or adding filtration) → discharging; can effectively reduce all contaminations in the sewage, water outlet reaches " integrated wastewater discharge standard " one-level B or one-level A standard.Simultaneously can effectively reduce whole construction costs and working cost.
