Description
Technical field
The present invention relates to the exploitation of environment pollution control new technology, more particularly to a kind of preparation side of organic waste water treatment agent
Method and application.
Background technology
With industrial boom, the type and quantity of waste water rapidly increase, and the pollution to water body is also increasingly extensively and tight
Weight, threaten the health and safety of the mankind.Because the composition of industrial organic waste water is more complicated, some are also toxic, industrial organic waste
Water process is more difficult also more important than municipal sewage treatment.
In high concentrated organic wastewater caused by industry, acid, bases are numerous, often with strong acid or strong basicity.Mainly have with
Lower harm：First, aerobism endangers：Due to biodegradation, high concentrated organic wastewater can make receiving water body anoxic or even detest
Death so as to produce stench, is deteriorated water quality and environment by oxygen, most aquatic organisms.Second, sense organ contact scar：High concentrated organic wastewater
Water body is lost use value, more have a strong impact on the normal life of the nearby water bodies people.Third, causing toxicity harm：Superelevation is dense
Contain a large amount of toxic organic compounds in degree organic wastewater, can constantly accumulate, store in the natural environments such as water body, soil, it is most laggard
Enter human body, be detrimental to health.
The processing method used at present mainly has：(1) oxidation-absorption method：Carried out just with coal dust after high-concentration waste water dilution
Walk coagulation, adsorption treatment, then with Fenton reagent catalysis oxidation and it is acid condense, then with coal dust coagulation, absorption.(2) burn
Method：Burning method is applied to processing high concentrated organic wastewater.Pretreated waste water is pressurized, filters, is delivered to after metering on chimney arch
Side, burner hearth evaporation burning is sprayed into by pressure-air atomization special nozzle.The method, can be right under conditions of safe operation of the boiler is ensured
High concentrated organic wastewater is thoroughly handled, its advantage be initial cost save, operating cost it is low.The method is present in actual popularization and application
Shortcoming is：1. waste water water is limited by matching boiler；2. labor is answered to waste component, it is ensured that do not influence boiler body combustion
Burn；3. the method needs further to be furtherd investigate in theory.(3) absorption method：Absorption method is to use consolidating with very strong adsorption capacity
Body adsorbent, the method for making one or several kinds of components in waste water be enriched in the surface of solids.The active charcoal of conventional adsorbent and
Resin, regenerating active carbon and elution are difficult；Resin adsorption has that usage range is wide, and inorganic salts are not influenceed in by waste water, absorption
Effect is good, and elution and regeneration are easy, steady performance, thus in ultra-high concentration organic wastewater processing, the most frequently used suction
Attached dose is resin sorbent.Resin adsorption method can be used for processing containing phenol, aniline, organic acid, nitro compounds, agricultural chemicals, dyestuff intermediate
It is a kind of effective ways for handling organic wastewater Deng waste water.(4) SBR processing：SBR sewage treatment process is modern activated sludge
One type of method, it is to be provided with one in the reactor of aeration and agitating device, according to predetermined program, carry out water-filling,
The operation of the process such as biochemical reaction, precipitation, draining, idle.This method is to utilize microbial degradation organic matter, but most of high
The industrial organic waste water biodegradability of concentration is very poor, institute's application prospect in terms of high-concentration industrial organic waste water processing in this way
It is limited.
The A of CN 104609597 disclose a kind of supper-fast method for removing organic pollutants, and this method, step is such as
Under：First, reducing agent is added into pending water；2nd, by the range of pending water pH regulations to 3-7；3rd, to pending
Water in add oxidant.This method is reacted using bisulfite and potassium permanganate or manganese dioxide, by producing height rapidly
The oxidant Mn (III) (non-complexing state) of activity, realizes the supper-fast removal to organic pollutants, can be potassium permanganate
The speed that pollutant is removed with manganese dioxide improves 1,000 to 1,000,000 times.But this method belongs to homogeneous reaction, after processing
Waste water contain a large amount of manganese and sulfate radical and be difficult to remove, and do not utilize reuse.In addition, the reaction needs in acid condition
Carry out, have certain requirement to the pH value of waste water, cause undesirable waste water to need regulation pH just can further react,
Reaction will also adjust pH value again to neutrality after completing, and waste time and energy.
Hydrotalcite-based compound (LDHs) is the compound formed by interlayer anion and the accumulation of positively charged laminate.Neatly
Stone chemical structure of general formula is：[M2+ 1-xM3+x(OH)2]x+[(An-)x/n·mH2O], wherein M2+And M3+Respectively it is located at main layer board
On divalence and trivalent metal cation, such as Mg2+、Ni2+、Zn2+、Mn2+、Cu2+、Co2+、Pd2+、Fe2+Deng bivalent cation and Al3 +、Cr3+、Co3+、Fe3+Hydrotalcite can be formed Deng Tricationic；An–For interlayer anion, inorganic anion can be included,
Organic anion, complex anion, same more and heteropolyanion；X is M3+/(M2++M3+) molar ratio, about 4:1 arrives
2:1；M is the number of interlayer hydrone.Its structure is similar to shepardite Mg (OH)2, main body is formed by the shared seamed edge of octahedron
Laminate.Divalent metal M on laminate2+Can in certain proportion similar in ion half price trivalent gold
Belong to cation M3+Same order elements so that laminate is positively charged, the positive charge on anion and laminate that interlayer presence can exchange
Balance so that LDHs overall structure is in electroneutral.The anion of interlayer can be exchanged, by a series of modifications, neatly stone material
Material can obtain the material of many kinds of different properties.
The content of the invention
The purpose of the present invention is to overcome the shortcomings of that separation is difficult in the prior art, condition is harsh, there is provided a kind of organic waste
The preparation method of water treatment agent.
The technical solution adopted by the present invention is in turn include the following steps：
Using commercially available or homemade hydrotalcite, the hydrotalcite and the sodium hydrogensulfite and height of respective amount that 20~50 mesh sieves will be crossed
After potassium manganate mixing, spray into corresponding water and keep hydrotalcite to moisten, the corresponding 0.3~0.6mmol sodium hydrogensulfites of every gram of hydrotalcite,
0.4~0.8mmol potassium permanganate and 0.1-0.2mL water, ground 20~40 minutes under 300~700rpm rotating speeds with ball mill,
Obtain organic waste water treatment agent.
The embodiment of the present invention further provides for the treatment of Organic Wastewater prepared by above-mentioned organic waste water treatment agent preparation method
Application of the agent in treatment of Organic Wastewater.
It is an advantage of the invention that：
Sodium hydrogensulfite and potassium permanganate are exchanged into hydrotalcite layers by dry method, are prepared into the water process of safety and stability
Agent, the dissociation of sodium hydrogensulfite is not by the pKa of sulfurous acid1Control, during reaction, pollutant is adsorbed to neatly rock layers
Between, so, whole reaction is carried out in such a confinement region of hydrotalcite layers, and react is influenceed by the pH value of water body in itself
It is smaller.
