Description
Technical field
The present invention relates to a kind of static bed biomembrane reactor, particularly relate to a kind of complex carries static bed biomembrane reactor with biofilm carrier and antibacterial carrier.
Background technology
The process of highly difficult trade effluent proposes very large challenge to environmental protection industry (epi), and taking it by and large trade effluent has following feature: 1) differences between industries are very large; 2) COD value is higher, often crosses ten thousand; 3) one-tenth is grouped into very complicated, and some molecule is difficult to degraded, and toxicity is very large; 4) some waste water saltness is very high, and it is even higher that concentration reaches 50g/L; 5) impact load is very large, can reach peak value in the short period of time.
Meanwhile, the biochemistry of the nitrogenous substances of trade effluent is removed extremely important equally because nitrogenous too high be one of major reason causing body eutrophication, and causing toxicity very high to fish of Ammonia material, nitroso-group is carcinogenic substance in addition.Can carry out biochemical treatment to nitrogenous substances by nitrification and denitrification, but the cultivation of nitrifier and denitrifying bacteria is abnormal difficult, this is because: 1) reproduction speed of these mushrooms is very slow, and productive rate is very low, is easy to be taken out of from reaction tank by waste water; 2) very high to the susceptibility of potential of hydrogen, temperature and salinity; 3) organic and inorganic inhibitory substance is very large on the impact of nitration reaction, often causes nitration reaction unstable.
Effectively can remove all kinds of pollution substances of trade effluent by using biomembrane process.Carrier filler is the core of biomembrane process.Microorganism can on its huge surface flourish, rapidly form highly active microbial film.Microbial film utilizes C, N, P etc. in water to carry out metabolism, thus plays the effect of purifying waste water.The good processing power that why has biomembrane process should give the credit to fixing microbial film in the carrier, can obtain very high biomass by it.The advantage of high-biomass makes biomembrane process have the ability of good reply toxic pollutants load impact, and still can keep the stability of whole treating processes when influent quality fluctuation is larger.The performance quality of carrier, directly have influence on biomass in the complexity of biofilm, reactor number, reactor for treatment effect quality.
Along with the development of environmental protection industry, there is the structure formation of multiple biofilm reactor, to adapt to different wastewater treatment requirements, be mainly divided into fixed bed, fluidized-bed and moving-bed three major types.Static bed biomembrane reactor structure is simple, and carrier filler homogeneous reactor is placed in bed.The difference of it and fluidized bed bio membrane reactor and MBBR is that carrier remains static.The advantage that static bed biomembrane reactor possesses in Industrial Wastewater Treatment: 1) microorganic adhesion on fixing carrier so do not need sludge reflux; 2) floor space is little: under the condition of identical pollution load, and the pond that static bed biomembrane reactor accounts for standard biologic reactor 20-40% holds; 3) being suitable for the dilatation of industrial effluent treatment plant: in view of the reserved area of most of waste water treatment plant is less, when actual influent quality and the water yield change, meeting original design Effluent criteria when ensureing that original design pond holds constant; 4) upgrading of existing industrial effluent treatment plant is suitable for: static bed biomembrane reactor design and operation is simple flexibly, adapt to dissimilar pond type, and very strong with the compatibility of other technique, can with most of technique of built waste water treatment plant as A
2o, AO, SBR and oxidation ditch process etc. are combined.Therefore be suitable for the upgrading of existing waste water treatment plant, make it meet emission standard; 5) feature that static bed biomembrane reactor had both had other biological embrane method anti impulsion load, mud age is long, excess sludge is few, occur without sludge bulking phenomenon, has again the high efficiency of activated sludge process and going slick property.On the other hand, temperature variation will be far smaller than the impact on activated sludge process to the impact of static bed biomembrane technique, and when temperature, sewage composition change or sewage toxicity increases, the tolerance of static bed biomembrane reactor is very strong.
As can be seen here, static bed biomembrane reactor has development and apply prospect very much, simple and easy to operate because building, existing conventional sewage plants can be transformed under the condition not increasing reactor volume, make it to improve organic clearance and the object reaching denitrogenation dephosphorizing.
But although static bed biomembrane reactor is obtaining very large development in recent years, it is also having its distinctive defect, as constantly growth under long-time running microbes cloth full carrier between space, passing through of block air and current.This blocking can cause the effective volume of reactor to reduce, finally cause the distributivity of air and current very poor and make system process result degrades, thus traditional static bed biomembrane reactor needs periodically back flushing, cleaning carrier and changes the complex operations problems such as aerator.
Summary of the invention
The invention provides a kind of complex carries static bed biomembrane reactor, can overcome traditional static bed biomembrane reactor needs periodically back flushing, cleaning carrier and changes the complex operations problems such as aerator.
In order to reach above technique effect, technical scheme of the present invention is as follows:
A kind of complex carries static bed biomembrane reactor, comprising: reactor, has the first carrier and Second support in described reactor.
Described first carrier is used for the biofilm carrier of biofilm development.
Described Second support is the antibacterial carrier that outside surface scribbles anti-biotic material; Described Second support is distributed between described first carrier.
Described reactor is aerobic or one in anaerobic type reactor.
The material of described first carrier and Second support is amino formate filler.
Preferably, described amino formate filler is polyurethane foam.
Preferably, described antimicrobial nano particle is antibacterial metal nanoparticle.
Further, described antibacterial metal nanoparticle is the combination of any one or more in gold and silver, copper, zinc, titanium.
Further, described first carrier and Second support arrangement mode in reactor can be the one in following four kinds of modes:
(1) by the first carrier, Second support two kinds of carrier mixing placing response devices.
(2) the first carrier, Second support two kinds of fillers are put into reactor successively by horizontally-arranged, it puts in order, and to be that the first carrier is placed first horizontally-arranged, and Second support is placed second horizontally-arranged, and the first carrier is placed the 3rd horizontally-arranged, by that analogy.
(3) the first carrier, Second support two kinds of fillers are put into reactor successively by vertical setting of types, it puts in order is that the first carrier places the first vertical setting of types, and Second support places the second vertical setting of types, and the first carrier places the 3rd vertical setting of types, by that analogy.
(4), the first carrier, Second support two kinds of fillers are put into reactor successively by the mode replaced, it puts in order is the first carrier, Second support, first carrier, Second support, the first carrier, Second support are placed first horizontally-arranged, Second support, the first carrier, Second support, the first carrier, Second support, the first carrier are placed second horizontally-arranged, the first carrier, Second support, the first carrier, Second support, the placement the 3rd of first carrier, Second support is horizontally-arranged, by that analogy.
