Description
Technical field
The present invention relates to sewage treatment area, more particularly to a kind of sewage oil removing granular preparation and preparation method thereof and should
With.
Background technology
At present, produce during processing, refinement, storage, transport and the use of oil large scale mining and oil product
Reveal and various oils garbages cause greatly destruction to water ecological environment, the oil spilling, oil stain in water not only reduces water ring
The quality in border, affects the circulation of food chain, destroys ecological balance, also threatens the health of the mankind.
Absorption method is a kind of method commonly used in sewage oil removal treatment, and wherein activated carbon is conventional in absorption method oil removing again
A kind of adsorbent.Activated carbon has strong affinity to oils and fatss, but the micropore size of activated carbon is extremely small, the emulsifying in sewage
Oil droplet easily gets lodged in the import of activated carbon capillary passage so that the micro channel is blocked, so that the internal surface area of micro channel
Lose absorbability.When all of micro channel is all blocked, then activated carbon is macroscopically showing oil suction saturation, but actually
Inner surface oil removing one kind " inanition " saturation of activated carbon, i.e., a kind of illusion saturation so greatly reduce activity
Adsorption capacity of the charcoal to oils and fatss, and then greatly reduce its deoiling effect.
The content of the invention
First technical problem to be solved by this invention is to provide a kind of deoiling effect good dirt for prior art
Water oil removing granular preparation.
Second technical problem to be solved by this invention is to provide a kind of above-mentioned sewage oil removing for prior art
The preparation method of grain preparation.
3rd technical problem to be solved by this invention is to provide a kind of simple structure, oil removing effect for prior art
Really good waste-oil scavenger.
The present invention solve technical scheme that above-mentioned first technical problem adopted for：A kind of sewage oil removing granular preparation,
Characterized in that, which is prepared from by the raw material of following mass fraction：2～5 parts of flyash powder, 2～5 parts of meerschaum powder,
2～5 parts of 1～2 part of binding agent, 1～2 part of porogen and surfactant.
Preferably, described adhesive be sesbania powder, polyacrylamide, at least one in Ludox.
Preferably, the porogen is Magnesium sulfate heptahydrate (MgSO4·7H2O), at least in sodium lauryl sulphate
Kind.
Preferably, the surfactant is PDDA, Jing after the surfactant is processed,
Oil removing granular preparation surface forms organic faciess, and its hydrophilic is transformed into lipophile, enhances its energy of adsorption to oil pollutant
Power.
Preferably, the particle diameter of the flyash powder is 200～225 μm, the particle diameter of the meerschaum powder is 10～
16 μm, match somebody with somebody so as to flyash powder and meerschaum powder can be made to form good level, be conducive to the shape inside oil removing granular preparation
Into micro channel, further increase the oil absorption inside oil removing granular preparation.
The present invention solve technical scheme that above-mentioned second technical problem adopted for：A kind of above-mentioned sewage removes oil particles system
The preparation method of agent, it is characterised in that including following preparation process：
(1) be modified absorption powder：Flyash powder is added with mass ratio as 1:4～5 be added to concentration for 0.4～
In 0.5molL-1 dilute sulfuric acids, after 24～36h of stirring, pull out, wash, dry, crush, obtain modified coal ash powder；
(2) batch mixing：By above-mentioned mass fraction, a certain amount of meerschaum powder, above-mentioned modified coal ash powder, binding agent are taken
And porogen, first porogen is put in the distilled water of 80～100mL, heating for dissolving at a temperature of 35～40 DEG C treats porogen
After being completely dissolved, binding agent is slowly added to, is stirring evenly and then adding into meerschaum powder and modified coal ash powder, be again stirring for
It is even to obtain mixture；
(3) pelletize：Obtained mixture is put in comminutor and is extruded into strips, cut into a diameter of 2 after drying～
3mm, length are the granular preparation of 2～3mm；
(4) activated particle preparation：Granular preparation obtained above is put in Muffle furnace carries out roasting, and sintering temperature is
250～300 DEG C, roasting time is 2～3h, obtains activated particle preparation.Different types of water during 3 are usually contained in meerschaum：
Absorption water (H2O), among being present in duct；Water of crystallization (OH-H), also known as water of coordination, is connected with magnesium ion coordination；Constitution water
(OH), link together with magnesium ion in octahedron.Above-mentioned three kinds of water removing under high temperature, so as to increase the fibre of meerschaum
The specific surface area between dimension and duct.It can be seen that, impact of the sintering temperature to the performance of meerschaum is larger, and temperature is too low, and the time is too short,
Active phase can not be formed；Temperature is too high, overlong time, may cause the aggregation of active phase and the transformation of crystal formation again, and the present invention is logical
Crossing above-mentioned roasting further improves the oil absorbency of meerschaum.
(5) sewage oil removing granular preparation：A small amount of distilled water, stir-activating, then by upper are added to the activated particle preparation
The surfactant solution that mass fraction adds concentration to be 0.5～0.75mmolL-1 is stated, constant temperature oscillation reaction at 40～50 DEG C
36～48h, after reaction terminates, centrifugation is washed to surfactant-free and is remained, and is dried, is crushed to 20～60 mesh and obtains sewage
Oil removing granular preparation.Jing after surfactant process, oil removing granular preparation surface forms organic faciess, and its hydrophilic is transformed into oleophylic
Property, enhance its absorbability to oil pollutant.
The present invention solve technical scheme that the 3rd technical problem adopted for：It is a kind of to remove oil particles system using above-mentioned sewage
The waste-oil scavenger of agent, including the housing with water inlet and outlet, it is characterised in that be additionally provided with the housing for adding
