Description
Technical field
The invention belongs to environment functional materials and water process new technical field, and in particular to one kind is administered based on black and odorous water
Paper mulberry biology carbon adsorbent and preparation method thereof.
Background technology
Phosphorus is the important element for leading to body eutrophication, excessive with the excessive emissions of agricultural, life and industrial wastewater
Phosphorus the phenomenon that being discharged into water body, water body is caused to show eutrophication, eutrophication can destroy the ecosystem, cause aquatic
The amount reproduction of plant, dissolved oxygen content declines in water body, and the toxin of Activities of Some Plants secretion can endanger aquatic animal, cause water body
Lose original balance.Secondly eutrophication can deteriorate water source, and transparency reduces and water body is muddy, generally in sepia
Or green.Excessive eutrophication leads to black and odorous water, and black and odorous water is serious water pollution phenomenon, and water body is made to completely lose use
Function influences landscape and human lives.Therefore a kind of method for being badly in need of looking for lower price high efficiency reduces the content of phosphorus in water body.One
As in removal water body the method for phosphorus have chemical precipitation method, bioanalysis, ion-exchange, membrane separating method, absorption method etc..It is wherein raw
Object carbon adsorption has many advantages, such as that floor space is small, simple for process, easy to operate, non-secondary pollution, finds high adsorption capacity, efficiently
The novel sorbents of rate and low price cost are the key points of the new dephosphorization process of exploitation.
Paper mulberry has the characteristics that fast-growing, adaptable, distribution is wide, easily breeding, heat height, the period of felling in turn is short.Lateral root is distributed very
Extensively, the speed of growth is fast, and rudiment power is vigorous, and resistance to trimming has stronger stain resistance.It is distributed in the torrid zone of China and temperate zone,
No matter there is distribution growth well in Plain, hills or mountainous region.Large stretch of paper mulberry is grown in Manganese Ore District, paper mulberry can Enriching soil
In manganese element.Using feed with paper-mulberry leaf powder, in high temperature and under conditions of being continually fed into nitrogen, make paper mulberry powder that high anneal crack occur
Solution generates concrete dynamic modulus, the paper mulberry charcoal with high specific surface area, and paper mulberry charcoal has the phosphorus in water body to be inhaled well
Attached effect, so as to effectively reduce the phosphorus concentration in water body.And the temperature for firing charcoal is different, hole, specific surface area and
Adsorption effect also can difference.
Invention content
The technical problems to be solved by the invention are：In view of the problems of the existing technology, a kind of of low cost, ratio of exploitation
Surface area is big, the efficient charcoal available for phosphorus in adsorbed water body.
The present invention proposes a kind of preparation method of paper mulberry charcoal, is that feed with paper-mulberry leaf is polished into powder, and powder is placed on and is continued
It is passed through under the hot conditions of nitrogen, it is made to be cracked into charcoal, concrete operation step is as follows：
（1）Feed with paper-mulberry leaf is picked, the feed with paper-mulberry leaf distilled water flushing picked is clean, it is placed at dry and ventilated and dries, then will
The feed with paper-mulberry leaf dried, which is placed on, to be dried to feed with paper-mulberry leaf in 30~80 DEG C of baking oven and is dehydrated completely, and the feed with paper-mulberry leaf being dehydrated completely is put into powder
Broken machine is polished into powder, finally screens paper mulberry powder by sieve, and pack is spare；
（2）By step（1）The paper mulberry powder screened is dispensed into the slot position of tube furnace, opens nitrogen valve, is continued
Nitrogen is passed through in toward tube furnace, treats that the air in tube furnace thoroughly empties, interior add will be managed with 5~8 DEG C per minute of warming temperature
To 200~1000 DEG C, 1~10 h of heated at constant temperature starts to cool down later heat, and temperature in pipe is made to be down to 20~80 DEG C, takes out and burns
The paper mulberry charcoal of system, pack obtain paper mulberry biology carbon adsorbent.
In above-mentioned preparation method, the sequence of preparation is the pretreatment for being first cleaned and dried and being crushed to feed with paper-mulberry leaf, then into
Row Pintsch process charcoal processing obtains the product.
It is applied to go the method for phosphorus in water removal, the method the present invention also provides a kind of above-mentioned paper mulberry biology carbon adsorbent
Include the following steps：A certain amount of phosphorus-containing wastewater is taken, it is 4~11 to adjust pH, and a certain amount of paper mulberry biology carbon adsorbent is added
Into waste water, the additive amount in every liter of waste water is calculated as 0.5~40 g with paper mulberry charcoal weight, is 100~300 rpm in rotating speed
Under conditions of rock 2~6 h of reaction, and controlling reaction temperature is 10~40 DEG C, filtered after the completion of reaction, by paper mulberry charcoal
Adsorbent and waste liquid separation, complete the removal to phosphorus in waste liquid.
Compared with prior art, the advantage of the invention is that：
1. extensive and cheap using raw material, primary raw material paper mulberry is widely present in nature；
2. the preparation process of paper mulberry biology carbon adsorbent of the present invention and easy to operate, prepare quick, with short production cycle, product returns
