Description
Technical field
The present invention relates to a kind of preparation method of Fructus Citri grandiss scytoblastema low-concentration chromate waste water adsorbent, belongs to adsorbent and prepares skill
Art field.
Background technology
Chromium is a kind of main pollutant in environment, and its important sources are exactly electroplating wastewater.With science and technology
Development, the scale of electroplating industry is increasing, and the chromate waste water amount of discharge is consequently increased, if effectively do not processed,
Greatly harm will be caused to environment.Valence state of the chromium in water environment is more, mainly based on trivalent chromium and Cr VI.Cr VI
Toxicity it is stronger, be generally acknowledged carcinogen, have high risks to human body.Trivalent chromium toxicity is weaker, is that a kind of humans and animals are required
Trace element.
The processing method of traditional chromate waste water mainly have chemical precipitation method, electrolysis, ion exchange, membrane separation process,
The physico-chemical processes such as active carbon adsorption, electrodeposition process, hyperfiltration.When in water, chromium concn is relatively low, these processing methods
Removal effect is bad, and economically also uneconomical.Biosorption process is a kind of emerging water technology, and microorganism is to each
Pollutant has relatively strong, adaptability faster.Biosorption technology is applied to into water treatment field and particularly processes heavy metal
Have broad prospects in terms of waste water and recovery precious metal.Prior art process high concentration heavy metal pollution when show compared with
High removal efficiency, but under low concentration and near-neutral sulfite deinking, removal efficiency is decreased obviously.From being applied at heavy metal wastewater thereby at present
The research of reason sees that the organism with biological activity and inactive biomass are respectively provided with stronger biological adsorption performance.Cell
The change that the structure of cell wall occurs after thirsting is conducive to Adsorption of Heavy Metal Ions, loses the organism counterweight of biological activity
The accumulation ability of metal is poor unlike active organisms, or even is higher than living body biological.This shows that agricultural-forestry biomass is used for a huge sum of money
Category wastewater treatment has Potential feasibility and advantage.
Biosorption technology is had the characteristics that compared with other common technologies：Biosorption process have process at low concentrations
Heavy metal effect is good, adsorption capacity is big, speed is fast, adsorption plant is simple, it is easy to operate the features such as, it is important that biological adsorption agent
Raw material sources are extensive, low price, have many to be industry, agricultural, the garbage of forestry.The process for using it for sewage can reach
The purpose of the treatment of wastes with processes of wastes against one another, while being conducive to reclaiming valuable heavy metal.
The content of the invention
Present invention mainly solves technical problem：Processing high for the materialization class method of current common processing waste water containing chrome
Higher removal efficiency is shown during concentration chromate waste water, but under low concentration and near-neutral sulfite deinking, removal efficiency is decreased obviously, located
Reason effect on driving birds is not good, is also easy to produce the defect of secondary pollution, there is provided a kind of to utilize Herba Spinaciae and Radix Betae enzymatic hydrolysis and fermentation to obtain fermentation liquid, then
Will the flesh of fish and vegetable mixing boil after boil in a covered pot over a slow fire and stew, centrifugation obtains hydrophilic pregnant solution, then by fermentation liquid and hydrophilic pregnant solution and pomelo peel
Flesh mixes, and adds coupling agent, the method that lyophilization is obtained adsorbent after stirring reaction, of the invention first with Herba Spinaciae and sweet
Hexavalent chrome reduction in waste water is trivalent chromium, is dropped by the oxalic acid with reproducibility, vitamin and organic acid in dish enzymatic hydrolysis and fermentation liquid
Low wastewater toxicity, the aminoacid that the organic carboxyl acid and the flesh of fish in recycling fermentation liquid is boiled in a covered pot over a slow fire in the centrifugal liquid after stewing have hydrophilic carboxylic
The principle of base, amino, by the Water Molecular Adsorption around chromium ion in waste water, makes chromium ion exposed out, finally with huge ratio
Chromium ion adsorption and enrichment is improve adsorption efficiency by the pomelo peel-flesh of surface area, is finally reached the purpose of processing waste water containing chrome.This
Obtained in invention, compound adsorbent handling process is simple, and raw material is easy to get, and high to the removal efficiency of low-concentration chromate waste water, reduction
Ability is strong, combines the advantage of physics and bioanalysises, and dosage is little, and processing cost is cheap, has broad application prospects.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is：
（1）It is 1 in mass ratio:1 is sequentially placed into Herba Spinaciae and Radix Betae in tissue pulverizer, and 20～30min of co-grinding obtains powder

3～5h of insulation enzymolysis at DEG C；
（2）After above-mentioned enzymolysis terminates, then the enterobacter cloacae of enzymatic hydrolysate quality 5% is added in ceramic pot, after sealing tank mouth
Fermentation tank is moved in greenhouse, heat-preservation fermentation 10～14 days at 35～40 DEG C are filtrated to get fermentation liquid after the completion of fermentation, will be sent out
Zymotic fluid is obtaining sterilization fermentation liquid after 10～15min of sterilizing at 120 DEG C in moving into high temperature sterilize tank, standby；
（3）Take after Ctenopharyngodon idellus are cleaned and gill, then artificial knife cuts the taking-up flesh of fish and fishbone, leaves complete fish skin, by what is taken out
The flesh of fish, fishbone and Lentinus Edodess, Horse hoof are 10 in mass ratio:1:2:Mince after 3 mixing, obtain fish young pilose antler, then fish young pilose antler is beaten into 200 repeatedly
Glue is played until fish is fine and soft, then is got back into the fish young pilose antler after glue is played in complete fish skin again for～250 times, fish skin is sutured with cotton thread, most
It is 1 afterwards in mass ratio:20 by after the fish after suture and water mixing, and the stewing stewed 10～12h of slow fire is collected by filtration filtrate, is put into centrifugation
Machine makes hydrophilic pregnant solution by oneself with 3000～4000r/min rotating speed 10～15min of centrifugal treating, isolated upper liquid, standby
With；
（4）The wax coat that pomelo peel knife cuts outer surface is taken, the white skin flesh of plumpness is left, skin flesh charcoal fire is fire-cureed into 3 first
Wash 3～5 times after～5min, dry, then the skin flesh after drying is put in jet mill that to be ground into particle diameter be 1～2cm's
Granule, obtains pretreatment pomelo peel-flesh granule；
（5）By pretreatment pomelo peel-flesh granule obtained above and step（2）Standby sterilization fermentation liquid and step（3）It is standby
The hydrophilic pregnant solution of self-control in mass ratio be 1:3:Load in reactor after 5 mixing, then in kettle, add pomelo peel-flesh granule total
The isopropyl three of quality 0.5%（Dioctylphyrophosphoric acid acyloxy）Titanate esters, at 40～50 DEG C, insulated and stirred reacts 5～8h, treats
Reaction discharges after terminating, and pomelo peel base low-concentration chromate waste water adsorbent is obtained after lyophilization.
The present invention concrete application method be：By Fructus Citri grandiss scytoblastema low-concentration chromate waste water adsorbent obtained in the present invention by throwing
Dosage is that 100～150mg/L puts into Cr6+During concentration is the chromate waste water of 150～180mg/L, start aerator aeration 20～
30min makes after adsorbent and waste water mix homogeneously recovery pond bottom mud after 1～2h of standing adsorption, process water can qualified discharge,
After testing, Cr in the low-concentration chromate waste water after being processed using the present invention6+Concentration is reduced to by 150 original～180mg/L
Below 5mg/L, clearance reach more than 96.6%, with splendid treatment effect.
