Abstract
The invention discloses a microbe magnetic carrier to dispose water, which is composed of pumice and magnetic material in the plastic case with hole on the surface, wherein the plastic case contains two semi-cases to connect through their connecting buttons; the diameter of plastic case is between 20mm and 150mm; the pumice is flow liner pumiceor basalt pumice or their composition; the grain size of pumice is 2mm-20mm, which is natural pumice particle. The invention is beneficial to attach and grow microbe, which provides excellent aerobic-anaerobic-aerobic environment to purify water.
Description
Technical field
The present invention relates to a kind of microbe carrier that sewage (waste water) is handled that is used for, relate in particular to a kind of microbe carrier of wandering about as a refugee of the biological bed technique that is used for wandering about as a refugee.
Background technology
When the biological bed technique of wandering about as a refugee is used for the sewage and waste water purifying treatment, have advantages such as processing efficiency height, the mud generation is few, floor space is little, the biological bed of the biological bed technique of wandering about as a refugee partly is made up of pond body, wander about as a refugee microbe carrier and aeration tube etc.Wander about as a refugee microbe carrier because surface-area is big, and provide huge biology to perch the space, make a large amount of microorganisms be able to apposition growth, be particularly conducive to the growth of autotrophic bacterias such as slower microorganism of some growths such as nitrobacteria, microbe carrier makes the residence time and the long-pending increase of gas-liquid surface in contact of bubble to the effect that bubble plays cutting, stops and adsorbs, and accelerates the transfer rate of oxygen, improved mass transfer effect and, reduced aeration rate the oxygen absorption ability.As seen, microbe carrier plays a part very crucial in the biological bed technique of wandering about as a refugee.
Water inlet is passed through between the ball from wandering about as a refugee, the ball internal resistance is big, flow velocity is slow, relative velocity is fast between ball, solid particulate, and is assembled to slow inner the moving of the ball of wandering about as a refugee of flow velocity therein by the fast place of flow velocity in the water, in the flow process through repeatedly moving and assembling, realized separating of solid particulate and water, this effect is called the effect of wandering about as a refugee.Genetic horizon flow phenomenon when effluent stream is crossed the microbe carrier surface, organism in the water and suspended substance are split on the carrier, and realization water separates with organism and suspended substance.The wander about as a refugee bottom of ball is equipped with aeration tube discontinuously and carries out aeration, forms aerobic-anaerobic environment, sewage through constantly aerobic-anaerobic treatment after and be purified, organism and suspended substance obtain more fully decomposing in the treating processes.
The ball of wandering about as a refugee is the earliest produced by Japanese AQUATECH company, adopts Resins, epoxy that rubble is bonded to the porous ball.The patent No. is the ball filler of wandering about as a refugee that 00218362.5 a kind of novel water treatment is used, think easily broken loosing in the manufacturing cost height of the ball of wandering about as a refugee that Japanese AQUATECH company produces and the use, influence wastewater purifying efficiency, propose to constitute the ball of wandering about as a refugee by the plastics spherical shell that has mesh and through chemically treated green stone rubble.The patent No. is 03277701.9 the macropore carrier that the is used for sewage disposal ball of wandering about as a refugee, think and use rubble following shortcoming to be arranged: the ability of load microorganism as the ball filler of wandering about as a refugee of microbe carrier, the microbe population that makes it possible to bring into play Decomposition is few, causes the decomposition efficiency of organism in the water and impurity low.In view of the above; this patent proposes the modification sponge as microbe carrier; place the hollow duroplasts ball of surperficial perforate to form filling ball the modification sponge, constitute the ball of wandering about as a refugee with netted hollow ball (interconnecting) by the wire that has plastic protective sleeve by some filling balls.Although this ball of wandering about as a refugee has the big characteristics of the microbe population of curing, the manufacture craft more complicated, cost is higher.
Summary of the invention
The present invention provides the microbe carrier of wandering about as a refugee that is used for water treatment that a kind of biofilm is fast, biomass concentration is big, treatment effect is good, sludge yield is few, making is simple, with low cost in order to overcome the deficiency that above prior art exists.
Purpose of the present invention realizes by following technical scheme: a kind of microbe carrier of wandering about as a refugee that is used for water treatment is characterized in that: be placed with float stone in the surface has the plastic casing of through hole.
Different shapes such as that the shape of described plastic casing can be is cylindrical, box-shaped.As preferred version, described plastic casing is spherical, is made up of two hemispherical Shells, and two hemispherical Shells connect by connector link.
The diameter of described baton round housing is between 20mm～150mm.
Described float stone is flow liner matter float stone or Black Warrior matter float stone or its mixture.
Described float stone is the natural pumice particle of particle diameter between 2mm～20mm.
When above-mentioned flow liner matter float stone is magmatic exhalation, owing to sharply reducing of pressure, the mineral that internal gas is overflowed rapidly and expanded and form, its inside has been full of steam bubble, with light weight, porousness is characteristics, has good water-retentivity and air permeability, and particle unit weight is 0.5～0.8g/cm
3, porosity is 69.5～71.8%, and water-intake rate is 50～60%, and outward appearance is a canescence.
Above-mentioned Black Warrior matter float stone is that the volcanics that has been full of bubble forms when solidifying, and lines is thicker, and the space is bigger, and particle unit weight 0.89～1g/cm3, water-intake rate are 10～20%, and outward appearance is sorrel or black.
The present invention has following advantage with respect to prior art:
(1) with the float stone particle be the main carrier of microorganism, wander about as a refugee ball relatively with existing, the roughness of carrier, porosity and avidity all more help adhering to of microorganism and grow, and biomass increases greatly, and biological activity is higher, and the water treatment decontamination effect improving is better;
(2) carrier has the environment of using aerobic-anoxia-aerobic, help the growth of different types of microorganisms, thereby set up the biological degradation environment that the mixing microorganisms flora is formed, sewage and waste water is through alternately aerobic-anaerobic treatment repeatedly, the removal efficient of water pollutant is improved greatly, and have the few advantage of excess sludge generation;
(3) float stone can adsorb the pollutent in the sewage and waste water, has improved the clearance of pollutent effectively;
(4) this carrier is formed with the baton round housing of natural pumice particle and surperficial perforate, makes simple, with low cost.
