Abstract
The invention relates to a process for preparing bio-ceramsite with fly ashes. 80-98 per cent of fly ash (dry-mixed), 0-12.5 per cent of clayey gangue, 0-2.5 per cent of additive and 2-5 per cent of water are proportionally mixed and stirred, and then sintered and molded at the temperature of 900-950 DEG C, prepared into a filler for a biofilter by sintering technology. The process is used in the fields of urban drinking water, light pollution treatment in water source places, urban industry, domestic sewage treatment, oilfield oil-water separation and deep well water treatment. The bio-ceramsite with fly ashes complies with national energy conservation and emission reduction policy. The urban solid waste is used for preparing fillers to treat municipal sewage, thereby presenting apparent environmental effect, social effect and economic effect.
Description
One, technical field
The present invention relates to a kind of environmental protection filtrate that is used for urban water supply and sewerage, preparation bio-ceramsite with fly ashes method belongs to environmental protection technical field.
Two, background technology
At present filler is most important in the effect of aeration tank, since the OTV S.A. under French CGF company develops aeration and biological technology first, has promptly adopted a kind of novel circular particulate filler (being artificial porcelain granule).This material provides the place of microorganism growth on the one hand, can hold back SS and excess sludge in the sewage on the other hand.Thereby the quality of filler directly has influence on the good and bad of microbiological deterioration organism performance in the BAF and has influence on the processing cost of Sewage Plant, reduces wastewater treatment and biologic packing material back-flushing operation energy consumption.
The present invention makes full use of product advantage own, and be attached to Ji Li, the characteristic of traditional filter material, the research and development bio-ceramsite with fly ashes, leca and the float stone made compared with Nonrenewable resources, its surface micropore of bio-ceramsite with fly ashes that adopts sintering grow and make is many, specific surface area is bigger than clay haydite, is more suitable for all kinds of microbial growths, and stable, firm.Adopt special sintering curre, the surface does not form glaze, and can require to make the haydite of different stacking densities according to Sewage Plant.Ultimate compression strength big (〉=6Mpa), and leca is generally at 3～5Mpa; Surface abrasion resistance is wiped, and anti acid alkali performance is strong, physics, chemical stability height, thereby long service life.Owing to sinter ball-type into, the filtering layer space is evenly distributed, and is difficult for stopping up, hardening, so the aquifer yield height.
Three, Fa Ming content
Bio-ceramsite with fly ashes main raw material of the present invention adopts 80～98% flyash (doing level mixes), clay matter coal gangue 0～12.5%; Admixture 0～2.5%, water 2～5% preparations meet the biological filter filler by the sintering process preparation.
Concrete processing method is as follows;
(1) flyash, clay matter coal gangue, admixture are measured in proportion, after the mixing and stirring,, be stirred to specified requirement with 2～5% water;
(2) adopt pan-pelletizer according to certain angle, rotating speed and time nucleation, balling-up quality green-ball in accordance with regulations;
(3) the sinter molding temperature is 900～950 ℃, is made into haydite according to certain sintering curre and temperature sintering;
(4) detect according to the product company standard.
Four, Fa Ming effect
Bio-ceramsite with fly ashes has that unit weight is light, intensity is high, thermal conductivity is low, refractoriness is high, heat-preserving anti-freezing, anticorrosive, shock resistance, antidetonation, wear-resisting and porous, specific surface area big (be quartz sand filter media 6～8 times), porosity big (be quartz sand 1.7～2.2 times) is easy to microbial film and generates and filtrates such as instead of clay haydite, float stone, quartz sand.Be used for urban drinking water, waterhead area and gently pollute fields such as processing, urban industry, sanitary sewage disposal, oil field oil water separation, phreatic water processing.Adopting bio-ceramsite with fly ashes to meet national energy-saving and emission-reduction policy, is to utilize municipal solid wastes to make stuffing product, administers municipal effluent again.Have significant environmental benefit, social benefit and economic benefit.
Five, embodiment
1, with flyash be 93%, coal gangue is 5%, water is 2%, temperature is 920 ℃, bio-ceramsite with fly ashes particle diameter 3～8mm.
2, with flyash be 90%, coal gangue is 5%, admixture is 2%, water is 3 thing haydite grains, 3～8mm.
3, with flyash be 95%, coal gangue is 5%, admixture is 2%, water for ℃, bio-ceramsite with fly ashes particle diameter 3～8mm.
Claims (2)
1. a kind of processing method for preparing bio-ceramsite with fly ashes of the present invention, it is characterized in that: prescription is weight percentage: flyash is 80～98%, coal gangue is 0～17.5%, admixture is 0～2.5%, water is 2～5%, temperature is 900～950 ℃, bio-ceramsite with fly ashes particle diameter 3～8mm.
2. its technology of the processing method of preparation bio-ceramsite with fly ashes according to claim 1 is:
(1) flyash, clay matter coal gangue, admixture are measured in proportion, after the mixing and stirring,, be stirred to specified requirement with 2～5% water;
(2) adopt pan-pelletizer according to certain angle, rotating speed and time nucleation, balling-up quality green-ball in accordance with regulations;
(3) the sinter molding temperature is 900～950 ℃, makes according to certain sintering curre and temperature sintering;
(4) detect according to the product company standard.
