Description
Technical field
The present invention relates to technical field of water purification, particularly, are related to a kind of preparation method of sewage water filtration composite sponge.
Background technology
In recent decades, China's industrial development is rapid.But in the past, the factory and enterprise in China does not focus on environmental protection,
Generally existing will not pass through the situation that purified sewage directly discharges.This year, with the continuous deterioration of environment, China's environment
Protection part has also carried out strict supervision to the discharge of sewage.All factories of enterprise, after sewage has to pass through purification, water quality symbol
After closing discharging standards, it could be discharged.
At present, the purification method of trade effluent is by including standing sedimentation, flocculation sediment and etc..Such as Authorization Notice No.
Chinese patent for 101928069 B of CN discloses a kind of purifying agent for polluted water, by polyhydroxyalkanoates, diatomite, humic acid,
Bioactivator, inorganic metal salt and other material compositions, the invention also discloses net using the sewage of the purifying agent for polluted water
Change method.The present invention, should due to the use of the slow-release material that completely biodegradable material polyhydroxyalkanoates is bioactivator
Completely biodegradable material is slowly degraded and release bioactive agent, realizes the long-term high-efficient purification function of bioactivator.
And combine water plant synergy to realize sewage phosphorus, nitrogen, polycyclic aromatic hydrocarbon, heavy metal purified treatment.
In addition to above-mentioned purifying agent for polluted water, also have currently on the market largely using activated carbon as the purifying agent for polluted water of main material,
Its principle is that water body is purified using the adsorptivity of activated carbon.
But above-mentioned water purification agent is limited to the clean-up effect of sewage, and it is poor to the adsorption effect of impurity, adsorption capacity is low, only
The change time is long, inefficiency.
The content of the invention
Present invention aims at a kind of preparation method of sewage water filtration composite sponge is provided, to solve sewage in the prior art
The technical issues of cleanser adsorption effect is poor, and adsorption capacity is low, and the clarification time is long, inefficiency.
To achieve the above object, a kind of preparation method of sewage water filtration composite sponge, comprises the following steps：
Step 1：By polyether polyol, isocyanates, neopelex, carboxymethyl cellulose, tin dilaurate two
Butyl tin and aluminium hydroxide 0.8-1.2 in mass ratio:1.2-1.6:0.01-0.03:0.04-0.06:0.01-0.03:0.1-0.3
It is uniformly mixed, foaming is stirred at 30-40 DEG C, uncooked foam material is made.
Step 2：By furfural, water soluble phenol resin, sepiolite powder, nanometer galapectite pipe, nano-crystal cellulose, polyethylene pyrrole
Pyrrolidone and water 3-5 in mass ratio:1:0.3-0.5:0.1-0.3:0.5-1.5:0.4-0.6:100 mixing, after stirring evenly
To mixed liquor A, the ammonium hydroxide that concentration is 1mol/L is added drop-wise in mixed liquor A under agitation until the pH value of mixed liquor A is
7-8；Then 16-48h is reacted at 55-65 DEG C, obtains colloidal sol.
Step 3：By foam material, colloidal sol, focus ratio 3-5 in mass ratio:1:0.2-0.3 is mixed, and at 130-150 DEG C
Under stir evenly, obtain mix-froth material；After mix-froth material is aged 12-24h, after being eluted with water, wet sponge is obtained.
Step 4：Wet sponge is dried using supercritical fluid, obtains sewage water filtration composite sponge.
In the inventive solutions, it is not changed to use using traditional flocculant or activated carbon as main component
Using polyurethane material and charcoal-aero gel as the composite foam sponge material of main base.Compared with activated carbon, composite foam sea
Continuous material possesses the duct of better adsorption capacity and sizes rank, the pore size in polyurethane foam sponge compared with
Greatly, the impurity of particulate species can effectively be adsorbed, the pore size in charcoal-aero gel is smaller, can be to heavy metal, pigment
Substances is waited to be adsorbed.Therefore it is stronger for the adsorptivity of the polluter of different size in water, species.In the preparation of foam material
In the process, neopelex plays foaming effect, and carboxymethyl cellulose can increase the degree of cross linking, di lauric dibutyl
Tin plays catalytic action, and aluminium hydroxide can be thermally decomposed at 130 DEG C or more, generates Alpha-alumina and vapor, vapor
After escape, play the role of pore.
And in traditional aeroge preparation process, during gel prepares aeroge by drying, by the inner
The intensity of the three-dimensional net structure in portion is not high, and original structure is easily caved in, and porosity and specific surface area is caused to reduce, and is molded
Material fragility is higher afterwards, and mechanical strength, toughness, poor water resistance have seriously affected practical application.The charcoal-aero gel material of the present invention
Material, using the composite material of charcoal-sepiolite-nanometer galapectite pipe-nano-crystal cellulose as matrix, wherein sepiolite has nano-scale
Hole, to the substances such as pigment, heavy metal ion have very strong adsorption capacity；Nanometer galapectite pipe is with hollow structure
Staple fiber tubulose has the duct of nano-scale, can greatly improve the intensity of material after charcoal-aero gel is made, and go back simultaneously
The toughness of carbon aerogel material can be improved, due to the presence of sepiolite, nanometer galapectite pipe, can be done in carbon aerogel material
It plays a supporting role during dry, the three-dimensional net structure in charcoal-aero gel is not easy to cave in, hole during so as to keep collosol state
Gap structure and specific surface area.Also, since sepiolite, nanometer galapectite pipe itself also possess nano pore, it may have strong to inhale
Attached property, therefore the hole lost by the space that sepiolite, nanometer galapectite pipe occupy can be made up.Nano-crystal cellulose not only from
Body can the heavy metal ion such as Adsorption of Lead, chromium, and the combination of each substance can be aided in when preparing colloidal sol；Polyvinylpyrrolidine
The duct of micron level can be made as pore-foaming agent in ketone, the pore size of sewage water filtration composite sponge is enriched, so as to right
Each pollutant is adsorbed.
Wherein during foam material, colloidal sol are mixed, added with focus ratio, focus ratio not only has viscous
Cooperation is used, and it can improve the water resistance of composite material, mechanical strength and resistance to shrinkage.Enable to sewage water filtration compound
Sponge operation in water for a long time.
Further, the preparation method of polyether polyol described in step 1 is as follows：By lignin and phenol 1- in mass ratio
2:15-25 is uniformly mixed, and 40-60min is stirred to react at 170-180 DEG C, and quality is at the uniform velocity added dropwise during reaction as 1.5 times of phenol
