Description
Technical field
The present invention relates to the technical field of sewage disposal, particularly relate to a kind of filler and preparation method thereof.
Background technology
BAF is the one in biomembrance process treatment process, and principle of work mainly loads filler in filter tank, take filler as carrier, the highly active microbial film of surface growth, the inner aeration in filter tank.Effluent stream through time, filling surface attached biological film, gives full play to the formation metabolism of microorganism, and the absorption of filler and crown_interception, processes sewage.In actual process, need specific surface area large, surface irregularity, is beneficial to microorganism growth, and quality is light, and density is little, the filler of stable chemical nature.
At present, the biologic packing material of high-specific surface area is generally class cylindricality or class ball-type, adopts the method manufacture of injection moulding.But this kind of biologic packing material smooth surface, load of microorganisms amount is low, is unfavorable for bio-film colonization and film growth, there is complex process, the caducous problem of use procedure simultaneously.
Therefore, be necessary to find that one has that specific surface area is high simultaneously, load of microorganisms amount is large, and production technique is simple, the filler that cost is low.
Summary of the invention
The present invention is directed to packing specific area in prior art little, load of microorganisms quantity not sufficient, complex manufacturing, high in cost of production shortcoming, provide one and have that specific surface area is high, load of microorganisms amount is large, and production technique is simple, the filler that cost is low
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
A kind of filler, it is the polyurethane foam containing activity charcoal powder, and wherein, activated carbon content is 3 ~ 7% of gross weight.
As preferably, the raw material of following mass percent is adopted to be processed into through foaming:
Polyethers is also called polyglycol ether; Suds-stabilizing agent is AK-8805 or B8433 or B8462 etc.; TDI is Toluene-2,4-diisocyanate, 4-vulcabond.Due to gac stable chemical nature, can not be out of shape in High Temperature High Pressure, one can be mixed after the product has been formed with filler, improve the porosity of filler, change independent activities charcoal in the past easily with the problem that waste water runs off, gac can long-term stability be fixed on plastic filler, the huge specific surface area had by gac and complicated pore texture, can by various microorganism, hard-degraded substance adsorbs lastingly, realize the degraded to hard-degraded substance, also the stop growth of difficult growth microorganism can be realized, thus filler can be made to have the stable function playing biochemical action.
A method for filler, comprises the steps:
Step (1): take polyethers, water, whiteruss, triethylamine, suds-stabilizing agent and methylene dichloride according to mass percent described in claim 2, get polyethers and water, whiteruss, triethylamine, the suds-stabilizing agent mix and blend of 0 ~ 20% part, adding methylene dichloride afterwards, stir, obtained A liquid;
Step (2): take TDI, gac and stannous octoate according to mass percent according to claim 2, mixes remaining polyethers in step (1) with TDI, gac and stannous octoate, obtained B liquid;
Step (3): by A liquid and the mixing of B liquid, after 8000 ~ 12000 revs/min of mix and blend 10 ~ 20s, pour foaming in foaming mould into.
Foaming working method is simple, and raw material is easy to get, and preparation cost is low, can be widely used in sewage treatment area.
As preferably, in step (2), in whipping process, control temperature is in 10 ~ 30 DEG C.
As preferably, after step (3), after foaming terminates, also need ageing 18 ~ 30h.
As preferably, ageing process control temperature is in 10 ~ 25 DEG C.
The present invention is owing to have employed above technical scheme, that produces has excellent gasdynamics performance containing gac urethane filler, volume density is little, specific surface area is large, adsorption efficiency is high, not easily run off in sewage treatment process, impel microbiologically stabilised flourish, thus ensure that filler has good biochemical degradation effect.
