Description
Technical field
The invention belongs to technical field of sewage, and in particular to a kind of aluminium manufacturer's sewage water treatment method.
Background technology
Aluminum i ndustry is the important foundation raw material industry of the national economic development.Since reform and opening-up, by decades
Effort, China has turned into world aluminum production, consumption big country, while also having evolved into the aluminium section bar production and processing of global maximum
State.However, as shown by data is held with industries such as transportation, construction industry, real estate, food packing industry, household electrical appliances and electronics
The development of continuous quick health, China's aluminium alloy extrusions market demand capacity is still very huge, and market prospects are very wide.
The development of aluminum i ndustry along with large amount of sewage generation, if its sewage without processing, arbitrarily discharge if, it is right
Environment causes great destruction, the safety of the drinking water of serious threat people.
The content of the invention
The purpose of the present invention is that there is provided a kind of aluminium manufacturer's sewage water treatment method the problem of being directed to existing.
The present invention is achieved by the following technical solutions：
A kind of aluminium manufacturer's sewage water treatment method, puts into sewage disposal ball, aluminium manufacturer's sewage per ton into aluminium manufacturer's sewage and puts into 5-10kg
Sewage disposal ball；
The sewage disposal ball is made up of three-decker, respectively sandwich layer, intermediate layer and outer layer, intermediate layer parcel sandwich layer, outer layer
Wrap up intermediate layer；
The sandwich layer presses 10-15 by activated sludge and fibert based active carbon:1 mass ratio is mixed；
The intermediate layer 3-5 is pressed by alga oligosaccharides, cyclodextrin, gelatin:6-8:4-6 mass ratios are mixed；
The outer layer adds ultra-fine carbon dust, sintering aid and binding agent, successively by 15-18 using diatomite as primary raw material:1-2：
3-6：0.5-0.8 mass ratio is mixed.
Further, the outer layer is hollow ball structure, and intermediate layer is hollow ball structure, the solid spherical structure in sandwich layer position.
Further, hazelnut shell is was crushed 120 mesh sieves by the fibert based active carbon preparation method, by overcritical
Carbon dioxide treatment, processing pressure is 6MPa, and processing time is 20-25min, and carbonization temperature is 380 DEG C, and carbonization time is 2 small
When, activation process is then carried out, temperature of living in is 620 DEG C, and soak time is 90min.
Further, the fibert based active carbon specific surface area is 2950m2/g, and micro pore volume is 0.34cm3/g.
Further, the sintering aid is bentonite.
Further, the binding agent is lac resin.
Further, the outer layer preparation method is：After diatomite is uniformly mixed with sintering aid, 250 mesh sieves are crossed, so
Calcined 2 hours at 500-540 DEG C afterwards, then naturally cool to 450 DEG C, add ultra-fine carbon dust, after uniform mixing, insulation
30min, then room temperature is naturally cooled to, then mixed with binding agent, outer layer is made.
The sewage disposal bulb diameter is 4cm, and the sandwich layer maximum gauge is 2cm, and intermediate layer maximum gauge is 3cm, outside
Layer maximum gauge is 4cm.
The present invention has advantages below compared with prior art：The present invention handles aluminium by using the sewage disposal ball of preparation
Factory's sewage, treatment effeciency is high, and high treating effect can handle 1 ton of aluminium manufacturer's sewage, energy every time using 5-10kg sewage disposal ball
Reach circular treatment 10-20 times；The sewage disposal ball prepared in the present invention is made of three layers of different structure, and sandwich layer is become silted up using activity
Mud is mixed with fibert based active carbon by certain mass ratio, by the association that fibert based active carbon is added in activated sludge
Same-action, can improve that simple activated sludge is poor to COD, ammonia nitrogen removal effect in sewage, and especially winter temperature is relatively low
In the case of, the drawbacks of effect is worse, by the way that activated sludge is wrapped in into sewage disposal core layer, can avoid activated sludge with
Water is washed dilution or reduces the situation of wastewater treatment efficiency because mud accumulation is fixed on bottom, by the way that sewage disposal is made
Ball, sewage disposal ball can pass through the diatom of the preparation on sewage disposal ball top layer with drainage flow without being destroyed by force by sewage
Soil, with fabulous adsorption function, can be adsorbed a large amount of suspension, silica in sewage well, in
Interbed can be acted synergistically with sandwich layer, and effective removal can be carried out to the COD in sewage, SS, ammonia nitrogen and other ions, be removed
Rate is good, and removal effect is thorough, efficiency high.
