Description
Technical field
The present invention relates to a kind of wastewater treatment material, and in particular in a kind of removal waste water the material for water treatment of particulate matter and
It is applied, and belongs to field of Environment Protection.
Background technology
Pollutant effluents is one of larger pollution sources in the current whole world.Such as electroplating wastewater, especially integrative electroplating waste have
The characteristics of having many pollutant kinds, complicated component, toxicity big and endanger serious, its major pollutants be various heavy from
Son, cyanide, spent acid and salkali waste etc..Plating, the waste water and waste liquid of printworks discharge, such as plating piece washings, useless tank liquor, equipment
Cooling water and flushing surface water etc., its water quality is different because of production technology, often contains gas chromatography, and waste water is poisonous, and harm is big.
As cyanogen can cause people and animals' acute poisoning, lethal, low concentration long term can also cause slow poisoning.Cadmium can make kidney occur disease
Become, and itai-itai can be caused.Cr VI can cause lung cancer, stomach tract disease and anaemia, and can be in bone, the dirty interior accumulation of spleen and liver.
Therefore, organic wastewater must be controlled strictly, be dealt carefully with.
The processing method of the existing waste water containing organic matter is:Directly sewage treatment plant is discharged to by sewage network to carry out
The processing of ammonia nitrogen and organic matter.Specific water treatment technology is a lot, including resins exchange, electrolysis, chemical method and air supporting etc..It is existing
Method of wastewater treatment have the following disadvantages：Electrolysis high energy consumption, power consumption and iron loss are high, high-concentration chromium-containing wastewater are produced dirty
Mud amount is too many, is not suitable with, while undesirable to cyanide wastewater processing；Chemical agent and Bubble-floating Method use chemicals redox
Neutralize, mud-water separation is carried out with air supporting floating method, a variety of organic additives, reality are contained because sludge is than great, and in waste water
Dissolved air flotation is not thorough when border is used, and operational management inconvenience；Chemical agent and precipitation are the methods applied earliest, are also most
Come in effective handling process, but after actual separation of solid and liquid long operational time, sedimentation basin, which has sludge, to be rolled up, and water outlet is difficult to protect
Demonstrate,prove stably reaching standard.And organic wastewater is that randomness is discharged into sewage network, the construction plan to sewage treatment plant brings pole
Big inconvenience；Sewage transport can give out dense stink into the way of sewage treatment plant, grow mosquitos and flies, be difficult to at stink
Reason, is unfavorable for environmental sanitation.So, in order to realize real effective processing of organic wastewater, it is necessary to research and develop at a kind of new water
Agent is managed, it can be used in the efficient process of waste water.
The content of the invention
It it is an object of the invention to provide a kind of sewage treating material, can be used for wastewater treatment, waste water can be greatly reduced
In content of organics.
To achieve the above object of the invention, the technical solution adopted by the present invention is：
A kind of preparation method of sewage treating material, comprises the following steps：
Silica-gel sphere is added in the dioxysulfate water aqueous solution, back flow reaction 45 minutes；Then suction filtration reaction solution, filter cake is washed
In the mixture that hexadecyltrimethylammonium chloride and propyl alcohol are added after washing, stir 15 minutes, add water, stir 5 minutes, then
Add NIPA；Then filter, added after filter cake drying in aqueous sodium acrylate solution, stirring after stirring 1 hour
20 minutes；Acrylic acid, urea and 2- acrylamide-2-methylpro panesulfonic acids are added, 75 DEG C are reacted 6 hours, continue to react
20 minutes；Last dry reaction liquid obtains solid, i.e. water treatment agent.
In the present invention, the mass ratio of the silica-gel sphere and the dioxysulfate water aqueous solution is 1: 2；The particle diameter of silica-gel sphere is 260
~400nm；In the dioxysulfate water aqueous solution, the concentration of sulfuric acid is 1mol/L, and the concentration of hydrogen peroxide is 0.5mol/L.
It is preferred that, the particle diameter of the silica-gel sphere is 300~320nm.
In the present invention, the silica-gel sphere, hexadecyltrimethylammonium chloride, propyl alcohol, the quality of NIPA
Than for 1: (23~25): 100: 10.
It is preferred that, the silica-gel sphere, hexadecyltrimethylammonium chloride, propyl alcohol, the mass ratio of NIPA
For 1: 24: 100: 10.
In invention, the filter cake, PAA, acrylic acid, the matter of urea and 2- acrylamide-2-methylpro panesulfonic acids
Amount is than being 100: 20: 19: (5~8): (12~17).
It is preferred that, the filter cake, PAA, acrylic acid, the matter of urea and 2- acrylamide-2-methylpro panesulfonic acids
Amount is than being 100: 20: 19: 6: 15.
The invention also discloses sewage treating material prepared by above-mentioned preparation method.
The invention also discloses the application of above-mentioned sewage treating material in the treatment of waste water.
In the present invention, Washing of Filter Cake mode is that filter cake is sequentially passed through into deionized water, ethanol, deionized water to wash.Going
Ethanol washing is added in the middle of ion water washing, the removal of silica-gel sphere surface impurity can be accelerated, be conducive to cetyl trimethyl
The attachment of ammonium chloride.
The present invention is using hexadecyltrimethylammonium chloride with NIPA to surface-treated silica-gel sphere
Progress is organically-modified, and during acroleic acid polymerization, silica-gel sphere can be well dispersed in polymer network；Simultaneously in urea
In the presence of, acrylate copolymer extent of polymerization is high, adds the stability of polymer, improves the activity of silica-gel sphere, be beneficial to
The interface stability of polymer and silica-gel sphere, so that there is provided the stable water treatment agent of excellent performance, it is good to be that wastewater treatment is laid
Good basis.
Adsorption technology is to trap the purpose that the nuisance being discharged into environment reaches processing by sorbing material, can be avoided to ring
The destruction in border, its core is sorbing material, and the traditional sorbing material and related adsorption technology by representative of activated carbon are being inhaled
The defect existed in terms of attached effect and technological operation, it is impossible to reach that industrialized administer requires that especially granular active carbon is used
When wastewater through organic matter contamination accident is disposed, the clearing and retrieving to floating on water toxic organic pollutant can not be realized at all, this
Graft (co) polymers effectively solve waste water as wastewater through organic matter inorganic agent outside the silica-gel sphere that invention is crossed by the use of HCl treatment first
In organic pollution, turn avoid existing chemical treatment, the side effect that brings of bioremediation.
