Abstract
The present invention relates to a kind of filler that is used for effluent treatment plant, be widely used in sewage treatment area.This filler is a main raw material with coal gangue or flyash, adds a small amount of forming agent, swelling agent, and through mixing, granulation, dry and high temperature sintering forms.Raw materials cost is low, technology is simple, result of use is good.Can be widely used in BAF, in the quick-decomposing biological bed apparatus of quick-decomposing biological treatment system and processing micro-polluted water.
Description
Technical field
The present invention relates to a kind of filler that is used for effluent treatment plant, be widely used in sewage treatment area.
Background technology
Along with the continuous progress of society, city size enlarges and human pay attention to day by day to living environment, and sewage purification has become one of vital task of social environment protection.The particularly use of BAF sewage water treatment method has improved the sewage water filtration ability greatly.The selection of its bio-carrier and filtrate, also only limit to materials such as haydite, zeolite, medical stone, coke, slag at present, its out-of-shape, though there is the plastics of use net to be bonded into spheroid as carrier or a plurality of particle, but all coarse at physical strength, specific surface area, erosion resistance, surface electrical behavior and wetting ability, porosity and area in various degree, density or material cost height, defectives such as transportation inconvenience.
Goal of the invention
The object of the invention is exactly the filler that a kind of a kind of effluent treatment plant that the cost of material is low, technology is simple, result of use is good will be provided.
Summary of the invention
It is a main raw material with coal gangue or flyash, adds a small amount of forming agent, and swelling agent is through mixing granulation, the filler that is used for effluent treatment plant that dry combustion method and high temperature sintering form.
Distinguishing feature
Of the present invention selecting materials is to turn waste into wealth, and coal gangue is the waste rock that gives off in the progress of coal mining, is a kind of large industrial solid castoff, the development and use coal gangue, and it is significant to make it form high value added product.
Complete processing is simple, and convenient transportation can process different sizes, different specific weight, difform biochemistry ball according to different demands.This filler can be applicable to BAF, substitutes the haydite of using at present, also can adopt the plastics guard to be directly formed to Ball-type packing, is applied in the quick-decomposing biological bed apparatus of quick-decomposing biological treatment system or processing micro-polluted water.
Embodiment
It is raw material machine-shaping that filler of the present invention is selected coal gangue or flyash for use, choosing main material accounts for more than 60%, proportion difference according to required biochemistry ball, adjust auxiliary material (swelling agent and clay) proportion, temperature of charge is controlled between 10～20 ℃, the humidity of adjusting material is between 8～15%, utilize mechanical-moulded machine, be pressed into the sphere of required diameter, ellipse garden or Polygons particle, particle diameter Φ 2mm～Φ 100mm (proportion is between 0.5～2.5), entering the freezing of a furnace that flashes back then, is sintering between 500～1500 ℃ in temperature, and lowering the temperature naturally by air combines with the cooling of forced-ventilated wind again, the control rate of temperature fall, through cooling, stack moulding, can obtain required sewage purification filler.
With coal gangue or flyash is raw material, getting 80% coal gangue utilizes ball mill to be ground into powder or the flyash of particle less than Φ 0.5mm, 15% clay, an amount of ratio raising agent and water mix, proportion (proportion is between 0.5～2.5) according to required biochemistry ball, adjust auxiliary material (swelling agent and clay) proportion, temperature of charge is controlled between 10～20 ℃, humidity is controlled between 8～15%, utilize roller briquetting machine, be pressed into Φ 20mm～Φ 40mm spheroidal particle, enter high temperature rotary kiln, in temperature is sintering between 500～1500 ℃, naturally lowering the temperature by air combines with the cooling of forced-ventilated wind again, and the control rate of temperature fall is through cooling, naturally stack moulding, can obtain required sewage purification filler.
Claims (1)
1, a kind of filler of effluent treatment plant is characterized in that it is a main raw material with coal gangue or flyash, adds a small amount of forming agent, swelling agent, and through mixing, granulation, dry and high temperature sintering forms.
