Description
Technical field
The present invention relates to haydite, be specifically related to a kind of gravel-shaped attapulgite active carbon ceramsite filter material.
Background technology
The active carbon specific area is large, and adsorption rate is fast, and degree of purification is high, is widely used in chemical industry, electronics, medicine, printing and dyeing, food and domestic water, water for industrial use, the removal of impurities of solution filter adsorption cleaning and decolouring.But the active carbon quality of supplying on the market is loose, hardness is lower, and under the effect of external force, micropore stops up easily, distortion and shedding, is difficult to maintain the original state, and the backwash water consumption that is used for water treatment is larger, and the price of active carbon is higher.
Mineral Resources in China 80% is intergrowth mineral, and a large amount of valuable resources retain among the mine tailing, and tailings impoundment need to take a large amount of soils.A lot of Tailings Dams exceed the time limit or excess load is used, even violation operation, make Tailings Dam have great potential safety hazard, and people's property and the life security of surrounding area caused serious threat.
Flyash is to receive the thin ash of catching the flue gas behind coal combustion, flyash also is the main solid waste that the coal-burning power plant discharges, be one of larger industrial residue of the current discharge capacity of China, along with the development of power industry, the flyash discharge capacity of coal-burning power plant increases year by year.A large amount of flyash does not add processing, will produce airborne dust, atmosphere pollution; Can cause the river to silt up if enter water system, and toxic chemical substance wherein also can work the mischief to human body and biology.
China Patent Publication No. CN 1065603A, in open day on October 28th, 1992, name is called " activated carbon haydite compounded filter material and manufacture method ", discloses a kind of activated carbon haydite compounded filter material and manufacture method.This filtrate and preparation method's characteristics are, add cork, hardwood flour or bone meal in the potter's clay that contains SiO2, Ai2O3, Fe2O3, CaO, MgO, are placed on that roasting increases the filtrate of making behind its hole again in the airtight container.Its effect is similar to active carbon.
Report according to inventor's result of the test: according to the production method of above-mentioned patent, in the potter's clay that contains SiO2, Ai2O3, Fe2O3, CaO, MgO, add cork, hardwood flour or bone meal, be placed in the airtight container roasting and can not make " activated carbon haydite compounded filter material ".The weak point of above-mentioned patent is: various batchings " adding water fully mixes thoroughly ", in airtight container through 800～1100 ℃ of roastings after 5～18 hours, because potter's clay and cork, hardwood flour and bone meal can not form an integral particle fully, potter's clay is a kind of sand shape, and cork, hardwood flour and bone meal have become ashes mostly, can't make " activated carbon haydite compounded filter material ".
