Abstract
The present invention relates to a filtering material with micropores and films for treating water, which has the following main components by the weight percentage: 30% to 60% of clay, 30% to 60% of loess, 5% to 20% of kaolin and 5% to 10% of pore forming agent. The product of the present invention is spherical haydite, has the characteristics of high mechanical strength, scour resistance, wearing resistance, stable physical and chemical properties, etc., and meanwhile, has the advantages of rich micropores, rough surfaces, big specific areas, long service life, corrosion resistance, favorable adsorbability, and less hardeness and loss amount, so the present invention has strong dirt catching capability and high filming efficiency, is favorable for growth and propagation of micro organisms and effectively removes organisms, suspended substances, nitrogen, phosphorus, etc., in water.
Description
Technical field
The present invention relates to the micropore filming filter material that a kind of water treatment is used.
Background technology
Present water treatment filter material mainly is to use irregular quartz sand to make filtrate, and it is big that quartz sand filter media has a resistance to water-flow, causes that easily air-water backwash filter stops up, backwash difficulty, easily shortcoming such as fragmentation.
Summary of the invention
Purpose of the present invention just provides a kind of micropore filming filter material, and it has the mechanical strength height, and retaining power is strong, and biofilm efficient height can effectively remove the middle organic matter that anhydrates, outstanding dirt and nitrogen phosphorus etc.
The present invention is achieved like this, and its key component is clay, loess, kaolin, pore creating material, and the percentage by weight of component is: clay 30-60%, loess 30-60%, kaolin 5-20%, pore creating material 5-10%, pore creating material adopts the bamboo powder.Production technology of the present invention is: the clay that will dry and pulverize; loess; kaolin (granularity 100-200 order) joins in the mixing kettle by formula ratio with pore creating material (granularity 100-200 order); mixed 20-30 minute; the material that will mix joins in the tumbling disk granulator then; add entry again and carry out granulation (granularity is controlled between the Ф 0.5-8mm); the mean residence time of material in comminutor is 20-30 minute; pellet is put in the baking room dries; join again after the drying and carry out sintering in the high temperature calcining kiln; temperature is controlled to be 1050-1250 ℃; time is 1-3 hour; produced thus micropore filming filter material shape is spherosome; the many micropores in surface, bulk density is 720-1150kg/m
3, density is 1230-2050kg/m
3
Product of the present invention is spherical haydite, characteristics such as having the mechanical strength height, anti-ly wash away, resistance to wear, physicochemical property is stable, simultaneously big, the long service life of abundant, the rough surface of its micropore, specific area, corrosion-resistant, absorption property good, be difficult for hardening, number of dropouts is little, therefore retaining power is strong, biofilm efficient height, be beneficial to growth of microorganism, breeding, can effectively remove the middle organic matter that anhydrates, suspension and nitrogen phosphorus etc.
The specific embodiment
Implementation method one takes by weighing clay 50kg, loess 35kg, kaolin 10kg, bamboo powder 5kg by prescription; kaolin oven dry was also pulverized 100 mesh sieves and 100 purpose bamboo powder are put in the mixing kettle; mixed 30 minutes; then mixed material is joined in the tumbling disk granulator; add suitable quantity of water again and carry out granulation; material stopped in comminutor 30 minutes; be put in the baking room then and dry; join again after the drying and carry out sintering in the high temperature kiln; temperature is controlled at 1200 ℃; 2 hours time, obtain spherical haydite thus.
Implementation method two takes by weighing clay 35kg, loess 50kg, kaolin 10kg, bamboo powder 5kg by prescription; clay, kaolin, loess oven dry are crushed to 200 orders; put in the mixing kettle with 200 purpose bamboo powder; mixed 20 minutes; then mixed material is joined in the tumbling disk granulator; add suitable quantity of water again and carry out granulation; material stopped in comminutor 20 minutes; be put in the baking room then and dry; join again after the drying and carry out sintering in the high temperature kiln; temperature is controlled at 1200 ℃, 2 hours time, obtains spherical haydite thus.
