Description
Technical field
The invention belongs to technical field of waste water processing, particularly a kind of Cheap highly effective is removed the wastewater treatment sorbent material and the filler of body eutrophication pollutent such as phosphorus in the waste water.
Background technology
Along with the industrial and agricultural production urbanization that develops rapidly and live, the sanitary wastewater, trade effluent and the farmland rainwash that contain nutritive substances such as higher concentration nitrogen, phosphorus import lake, reservoir and river, and in water body, accumulate, stimulate algal bloom in the water body, cause in the fresh water water body that promptly common alleged body eutrophication takes place " red tide " in " wawter bloom " and seawater.The standard that American National Environmental Protection Agency (EPA) divides body eutrophication is exactly that total phosphorus concentration is greater than 0.02mg/L.The ground water environment quality standard of China's regulation is that total phosphorus concentration is less than 0.1mg/L (GB3838-88).Therefore remove in the water body pollutent particularly the phosphorus in the waste water have great importance to preventing body eutrophication.
Usually the method for removing phosphorus in the water body has biological process, chemical method and absorption method.Biological phosphate-eliminating is meant that generally the dephosphorization bacterial that utilizes in the active sludge can this process of huge uptake phosphorus in aerobic environment.But in case be in anaerobic state, dephosphorization bacterial will discharge the excessive phosphorus in the cell, so the dephosphorization instability, and exists the phosphorus containing sludge disposal concerns.Chemical dephosphorization is meant by adding chemical agents such as calcium salt, molysite or aluminium salt and forms the insoluble phosphate precipitation, by solid-liquid separation the phosphorus in the waste water removed then.There is also the working cost height, control condition complexity, operation shortcoming such as loaded down with trivial details.
Sorbent material can be divided into three types to the absorption of phosphorus: physical adsorption, chemical precipitation and physical and chemical adsorption.Physical adsorption is meant: phosphoric acid salt is a kind of more difficult dissociated compound, might be subjected to the absorption of solid surface energy, and relatively concentrate on the interface of solid-liquid phase.This absorption generally is reversible, and free energy is lower, discharges than being easier to.Chemical precipitation is: positively charged ions such as calcium, magnesium, iron, aluminium can produce the very little compound of solubleness with phosphoric acid salt.Therefore, phosphate anion easily produces chemisorption and is fixed.The chemisorption reversibility is little, is adsorbed to form the very difficult release in back.Physical and chemical adsorption is: since solid phase surface with negatively charged ion, make the phosphate radical anion in the solution be attracted to solid phase surface by ion-exchange.The energy variation of this absorption is between physical adsorption and chemisorption.The phosphate ion of absorption can be other ion and replaces out.
The sorbent material of iron content, aluminum compound to the absorption of phosphorus and fixing mainly be chemical precipitation, physical adsorption and machinery close and hold.Ferric oxide, aluminium mineral can also adsorb phosphoric acid from the teeth outwards except by precipitation and exchange absorption and the phosphorus effect.It is when ironic hydroxide or alumine hydroxide colloid cohesion that machinery closes the effect of holding, and the phosphoric acid in the solution is closed hold in gelinite, or be wrapped in calcium phosphate precipitation or other phosphorous solid surface, reduces its solubleness.Three kinds of modes that iron, aluminum oxide adsorb phosphorus, simultaneous often.
Adopt absorption method to phosphorus adsorb remove have simple to operate, with low cost, be convenient to reclaim advantages such as useful resources, sorbent material can be recycled.The general phosphorus adsorbent that uses mainly comprises activated alumina, natural materials (as red soil, flying dust etc.) and synthetic sorbent material (as gac).A common weak point of the sorbent material of known natural and simple modification is that adsorptive capacity is all on the low side, though and the high-performance water treatment absorbent loading capacity height of synthetic exploitation, cost costliness, and can not being applied directly in the composite waste of high density.
Filler has a wide range of applications in the wastewater treatment, bio membrane processes such as the biological contact oxidation process during trade effluent, sanitary wastewater are handled, biological fluidized bed, BAF, it is a kind of high-efficiency wastewater treatment, and filler is the core of this technology, no matter be that filler all plays an important role in aerobic, double oxygen or the anaerobic process.Along with increasing the weight of day by day of pollution of waterhead, in the biological pre-treatment process of feedwater micro-polluted raw, filler has also been brought into play important performance.
Trade effluent, sanitary wastewater are handled in the biomembrance process wastewater treatment, and filler plays fixed biomembranous effect, is the core of membrane process craft, and the success or failure of technology have direct relation with the filler of selecting for use.When generally selecting filler for use, take all factors into consideration following some: 1. surface irregularity, the hole prosperity, suitable microorganism grows within it; 2. microorganism colonization is fast, the aging microbial film stability that easily comes off 3., require filler can be antiacid, alkali resistant, resistance to oxidation, readily biodegradable is difficult for aging etc.; 4. installation and maintenance are convenient; 5. light weight, physical strength is big; 6. low price, wide material sources etc.Select appropriate filler, can shorten the reaction times of technology, improve operating performance and operation stability etc.Filler commonly used in these technologies has, as biological ceramic particle, gac, zeolite, diatom scholar, quartz sand, oyster shell and some artificial synthetic inorganic light weight carriers, the characteristics of these fillers are need not the installation work of above-mentioned filler, only need be positioned in the treatment unit during application and get final product, easy to use, and change simple, therefore having reduced installation and operation management workload, is the development trend of filler from now on.This filler of many uses in the biomembrance process waste water treatment process, but these fillers generally do not have the function of absorb polluted matter in wastewater treatment, minority has the filler of outstanding absorption property, as gac, and but price very high (as 1000～3000 yuan/ton of gacs); To the well behaved zeolite of ammonia nitrogen absorption in the waste water (but it is to phosphorus weak effect), price is also wanted 400～600 yuan/ton.
Summary of the invention
One of purpose of the present invention provides a kind of phosphorus adsorbent that is used for wastewater treatment.
