（2）Weigh cocoanut shell be put into pulverizer crush 2~3h after obtain pulverized particles, by pulverized particles and above-mentioned enzymolysis filtrate
It is fitted into fermentation tank as fermentation substrate after mixing, then bed-silt is added into fermentation tank, stirred evenly with stirring rod rear close
Sealed cans mouth is sealed by fermentation；
（3）Wait for it is above-mentioned be separated by filtration to obtain fermentation filter residue after fermentation, the nitric acid for being 30% by ferment filter residue and mass fraction
Ferrous solution mixes, and is put into the reaction of sonic oscillation instrument sonic oscillation, filters after reaction, isolated reaction filter cake；
（4）Above-mentioned reaction filter cake is put into retort, carbonization reaction is kept the temperature under nitrogen protection state, is gone out after charing
Material, obtains from preparing active carbon, will be mixed to get pre-reaction from preparing active carbon and potassium rhodanate and amino trimethyl phosphonic acids and water
Object；
（5）Above-mentioned pre-reaction object is fitted into autoclave, high-temperature high-voltage reaction, takes out reaction product mistake after reaction
Filter, isolated filter cake are from regenerated carbon；
（6）Count in parts by weight, weigh 15~20 parts of polyethylene, 50~60 parts it is above-mentioned from regenerated carbon be mixed 30~
Mixed material after stirring is placed in mold, and moves into baking furnace by 40min, forms by a firing and comes out of the stove, is cooled to 40~60
DEG C demoulding is to get from regeneration activity filtration core.
Step（1）Described in agrocybe, soybean and pineapple mass ratio be 5:2:7, mixed powder minces and protease
And the mass ratio of water is 10:1:100, the temperature of enzymolysis is 25~28 DEG C, and enzymolysis time is 6~8h.
Step（2）Described in pulverized particles and enzymolysis filtrate mass ratio be 1:3, the addition of bed-silt is fermentation
The temperature of the 5% of substrate quality, sealing and fermenting is 30~40 DEG C, and the time of sealing and fermenting is 3~5 days.
Step（3）Described in fermentation filter residue and mass fraction be 30% the mass ratio of iron nitrate solution be 1:10, ultrasound
The frequency of oscillating reactions is 25~30kHz, and the time of sonic oscillation reaction is 1~2h.
Step（4）Described in heat preservation carbonization reaction temperature be 300~400 DEG C, keep the temperature carbonization reaction time be 2~
3h is 10 from preparing active carbon and potassium rhodanate and the mass ratio of amino trimethyl phosphonic acids and water:1:1:5.
Step（5）Described in the pressure of high-temperature high-voltage reaction be 2.3~2.5MPa, the temperature of high-temperature high-voltage reaction is
200~220 DEG C, the time of high-temperature high-voltage reaction is 8~10h.
Step（6）Described in the temperature formed by a firing be 200~250 DEG C, the time formed by a firing be 1~2h.
The beneficial effects of the invention are as follows：
The present invention digests first using the biomass rich in amino acid as raw material after co-grinding, then will enzymolysis filtrate and coconut shell flour
Mince blending fermentation, will fermentation filter residue and iron nitrate solution mix carry out sonic oscillation reaction, then will reaction filter cake charing after and
It is reacted under high-temperature and high-pressure conditions after potassium rhodanate and the mixing of amino trimethyl phosphonic acids, note film is burnt after the mixing of final and polyethylene
System is obtained from regeneration activity filtration core, and the present invention obtains the enzymolysis liquid rich in amino acid by enzymolysis first, by enzymolysis liquid and powder
Porous cocoanut shell particle after broken is mixed and is sealed by fermentation in the case where being acted on rich in the bed-silt of microorganism and humic acid, is passed through
Amino acid and humic acid degradation are generated a large amount of pendant carboxylic groups and amino and other active groups by microorganism, and in microorganism
These pendant carboxylic groups and amino and other active groups are introduced into pore interior and the surface of cocoanut shell particle under effect,
Then by the cocoanut shell containing carboxyl and amino and iron salt solutions hybrid reaction, the metal ion chela of pendant carboxylic group and amino is utilized
Iron ion chelating is anchored at internal void and the surface of cocoanut shell particle by conjunction property, and the introducing of other active groups increases coconut palm
Activated adoption bit number of points in shell particle, then through high temperature carbonization, the activated carbon containing metal ion is obtained, it will then contain metal
The activated carbon of ion is blended with potassium rhodanate and amino trimethyl phosphonic acids, under conditions of high temperature and pressure so that in activated carbon
Part metals ion removes, and generates metal cavity in activated carbon internal void and surface, the generation in these holes makes this hair
Bright activated carbon oxidation obtained greatly improves, and after active carbon filter core use, organic impurities reaches absorption in the water of absorption
After saturation, activated carbon and the water reaction being in contact with it generate the extremely strong hydroxyl radical free radical OH of oxidisability, it can be with activated carbon
The organic matter adsorbed in filter core generates organic free radical and is allowed to structure destruction, and oxygenolysis is finally reached voluntarily regenerated purpose,
So that active carbon filter core absorption property produced by the present invention is lasting, effluent quality is lasting, without often replacing, has wide
Application prospect.
