The purifying treatment that the biological bed technique of wandering about as a refugee is applied to sanitary sewage, trade effluent has the efficient height, does not produce the advantage of mud.On the biological bed of wandering about as a refugee, load the ball filler of wandering about as a refugee, the process that effluent stream is purified through wandering about as a refugee ball can point two stages: the fs is to use the technology of wandering about as a refugee, organism and ss suspended solid in the sewage are enriched in the ball filler of wandering about as a refugee, and realization water separates with organism, suspended substance; Subordinate phase is to wander about as a refugee the microorganism cultivating in the ball filler and bacterium under the aeration effect, the anaerobic-aerobic process that hockets repeatedly, thus mud such as organism and suspended substance can be decomposed into carbonic acid gas, water and solvability inorganic salt.Making flows through, and the wander about as a refugee sewage of ball is purified and does not produce mud, does not also just need second pond, concentration basin, digester etc.

At present, the ball filler of wandering about as a refugee that the technology of wandering about as a refugee is required has only Japanese AOUATECH company to produce, and these balls of wandering about as a refugee are to adopt Resins, epoxy that rubble is cohered into the porous ball and make.The manufacturing cost height of ball but this is wandered about as a refugee, import price is about 7000 yuans/cubic metre, and easily broken loosing in the use, influence the flow field of effluent stream through the ball of wandering about as a refugee, influence biofilm and distribute water and air performance, influence the stop over effect that space produced of effluent stream inside and outside the ball of wandering about as a refugee, weaken biochemical reaction, also just influence wastewater purifying efficiency.

The purpose of this utility model is a kind of ball filler of wandering about as a refugee of design, and it can reduce manufacturing cost significantly, and the interior rubble of ball that guarantees simultaneously to wander about as a refugee can not break diffusing, thereby improves water treatment effect.

In order to achieve the above object, the utility model is realized by following scheme.It is made up of the gravelly ball of wandering about as a refugee that is filled with in plastics spherical shell that has mesh and the plastics spherical shell through chemical treatment.When effluent stream is wandered about as a refugee during the ball filler through of the present utility model, on the one hand mud such as organism and suspended substance are stopped over through chemically treated rubble, automatically the microorganism and the bacterium of growth on the rubble on the other hand, under aeration condition, through alternative anaerobic-aerobic effect repeatedly, mud under stopping over is decomposed into carbonic acid gas, and water and solvability inorganic salt have reached the purpose of no mud discharging in the scavenging process.

Above-mentioned plastics spherical shell is bited into one by the shrinkage pool and the boss of two hemispherical Shells by mutual coupling.Rubble is a cun sub-stone, and promptly the rubble diameter is 2.5-3.5cm.Mesh can be circular, rhombohedral or polygonal.

The utlity model has following advantage:

1. because the utility model is made up of through the chemically treated gravelly ball of wandering about as a refugee filling in the plastics spherical shell that has mesh,, only be the 1/4-1/6 of the price of the Japanese ball of wandering about as a refugee that produces so the utility model is simple in structure, easy to make, and is with low cost.Because of can not be loose need not maintaining and replacing, reach and once invest life-time service.

2. it is effective to have adopted the utility model to handle purification of waste water, and specific activity mud method and biomembrance process COD clearance are high by 10%.And operation running cost is also low: because mud such as organism in the waste water of the present utility model of flowing through and suspended substance can be stopped over effectively, fully with the ball filler of wandering about as a refugee on microorganism biochemical action takes place, the mud branch is taken off, removed from the operation operation of removing mud.

3. do not produce mud when having adopted the ball filler of wandering about as a refugee of the present utility model to dispose of sewage, so save loaded down with trivial details sludge treatment facilities such as second pond, concentration basin, digester, further reduced the equipment investment cost of purification of waste water, the 1/2-1/3 that can reduce investment outlay compares with the facility investment of traditional sewage work.
