Description
Technical field
The present invention relates to the filtration of water treatment field and administer material, is that a kind of novel inorganic filter material is flyash film and filler, relates in particular to the flyash agglomerated material for water treatment.
Background technology
At present, the total utilization of PCA approach is concluded and is mainly contained following 7 kinds both at home and abroad:
1. powder ash air-entrained concrete.Powder ash air-entrained concrete is the materials for wall novel, that light thermal-insulation is energy-conservation.Main raw material is flyash, accounts for about 70%, and other is lime, cement, gypsum, foaming agent etc., and these raw materials are made through processing the operations such as multiviscosisty, cutting, steam press maintenance of preparing burden, stir, pour into a mould, get angry.Can be used as roof heat insulation, safeguard wall, partition wall, also can do uppermost storey and be five layers bearing wall, use the exterior wall and the seismic region that are specially adapted to Highrise buildings infilled wall, cold district, it is heavy to alleviate wall, increases usable floor area.
2. flyash concrete holllow building block.In recent years, flyash concrete holllow building block development is very fast, and its main raw material is flyash, gather materials, cement etc., and raw material is made through operations such as batching, stirring, moulding, maintenances.In normal concrete building block and light aggregate concrete building block, also can mix flyash, but add as adulterant.And in coal ash concrete blocks, flyash be adulterant be again fine aggregate, volume is higher.
3. cement, flyash expanded perlite concrete insulation blocks.Its technical process is similar to the flyash concrete holllow building block basically.The perlite building block has in light weight, good heat insulating, and characteristics such as certain intensity are arranged, and the factor that influences density and intensity has: perlitic volume, the ratio of flyash and cement and the control of technical process.Also can add an amount of admixture, to improve block strength.
4. flyash concrete pavior brick.The flyash concrete pavior brick is that the epoxy glue ramming material is equipped with coarse aggregate etc. again with cement and flyash, raw material is made through metering stirring, moulding, maintenance, the change forming mould can be made into square brick, chain pavior brick, brick modelled after an antique, the pavior brick of greening kind of careless brick, curb piece and other shape etc.
5. flyash brick.Be main raw material with flyash, lime, admixture proper amount of gypsum and aggregate are through blank preparation, compression moulding, the flyash brick that high pressure or atmospheric steam curing form.
6. lytag and concrete product.Haydite is a kind of artificial lightweight aggregate.Lytag is main raw material with flyash, through the processing balling-up, and the lytag that is called that sintering or burning expand and form.The title non-sintering powdered coal ash light-weight aggregate that forms through normal temperature or vapor cure.Lytag can be used for novel wall materials such as large-scale Side fascia and concrete segment.
7. flyash concrete light cellular partition board.Mainly be on the basis of slight wallboard, add the slight partition plate of part flyash production during batching, or with the slight wallboard of cement fly ash foam concrete production.
8. in addition, flyash also can be used for synthetic fertilizer, as waste water, and purposes such as the flocculation agent of waste gas
And for a long time, utilization of coal ash only limits to construction industry, and the chemical ingredients that takes full advantage of flyash self is carried out commercialization and produced seldom, therefore causes it to utilize shortcoming economy, reasonableness, and utilization ratio is low, and range of application is narrow.Though have utilization of fly ash research and development achievement to consider the characteristics of flyash self chemical constitution, utilize wherein SiO
2, as resource, produce with SiO
2Be main product, but owing to need high temperature to add alkaline sintering, its production technology process complex operations has certain difficulty, power consumption and wastewater flow rate are big; And Fe, Al component fail effectively to utilize in the flyash, make its The Application of Technology be subjected to restriction to a certain degree.
Above-mentioned utilization also only is small portion, and most of flyash needs landfill to dispose, and brings serial problems such as the land occupation area is big, environmental pollution thereupon.For a long time, though China's total utilization of PCA is subjected to the attention of country always, and obtain certain research and development achievement.But it is mainly used in materials for wall, Cement industry and road-making material aspect, and range of application is narrower, and especially the product of researching and developing from the flyash chemical composition that utilizes achievement very less and develop is single.As producing white carbon black with the sodium carbonate roasting method because its power consumption is bigger, product single, the chemical composition of failing to take full advantage of in the flyash makes its application be subjected to certain restriction.Therefore how economical, rationally, take full advantage of flyash self chemical constitution characteristics, and it is developed, utilizes as resource, it is transformed into has many kinds, and have the product of higher economic worth, just seem very important and significant; It simultaneously also is the key point that solves the existing problem of flyash.Propose in National Development and Reform Committee's issue " Eleventh Five-Year Plan comprehensive utilization of resources instruction ", reach 75% to total utilization of PCA rate in 2010.The present invention carries out research and utilization from the chemical ingredients of flyash, for the comprehensive utilization of flyash is opened up a new road.
Al, Fe and SiO in the flyash
2Accounting for 85%～90% of full component, is the big characteristics that flyash is formed; Can take full advantage of these characteristics, adopting advanced person and effective production technology to be converted into practical economical product, is the key of total utilization of PCA. patent 201010117032.1 usefulness flyash are produced hydrated SiO 2 and ferro-aluminum is water conditioner. utilized to contain Al, Fe and SiO in the flyash
2With other trace metal, but Production Flow Chart is long, and product is single. do not take full advantage of.
Ceramic membrane (ceramic membrane) is a kind of in the mineral membrane, and ceramic membrane also claims the CT film, is a kind of of solid film, and company of Dai Nippon Printing and the Toyo Ink company by Japan introduces market exploitation in 1996 the earliest.Mainly by Al
2O
3, ZrO
2, TiO
2And SiO
2Etc. the porous-film of inorganic materials preparation, its aperture is 1-50nm.It is good to have chemical stability, acidproof, alkaline-resisting, the organic solvent-resistant of energy: physical strength is big, but counterflush: anti-microbe ability is strong: high temperature resistant: pore size distribution is narrow, characteristics such as separation efficiency height, in foodstuffs industry, biotechnology, environmental engineering, chemical industry, petrochemical complex, control field such as metal working industry and obtained using widely, its market sales revenue is developing with 35% annual growth.Ceramic membrane is compared with similar plastics, involve great expense, but have many advantages, it is hard, holding capacity is strong, durable, the difficult obstruction, to having chemical invasive liquid and high-temperature cleaning liquid stronger resistivity is arranged, its main drawback is exactly expensive complicate fabrication process, is applied in special occasions, is difficult to big area and promotes.
In the existing sewage disposal, often in the anaerobic and aerobic technology use various fillers, plastics are arranged, inorganic, all carry additionally microbial film as a kind of carrier, itself does not participate in its reaction process.
The technical scheme that the application proposes is to utilize the porousness of flyash, adsorptivity, and contain the chemical property of multiple compound, and adding an amount of additive, catalyzer etc. utilize known sintering technology and activating technology manufacturing.
