Description
Technical field
The invention belongs to technical field of sewage more particularly to a kind of wastewater treatment adsorbent material and preparation method thereof.
Background technique
Include a large amount of organic pollutants and contents of many kinds of heavy metal ion in the sewage being discharged in industrial production, and most has
Machine pollutant is existed in the form of water-soluble sodium salt.Due to its stable chemical structure, not with light, water and many chemical substances
It decomposes reaction, therefore, pollutant is once released in water body environment, just extremely difficult to be removed, it is necessary to be put into receiving stream
It is adsorbed before.Meanwhile the heavy metal ion in sewage and the haemocyanin in humans and animals blood plasma interact, and will affect
The metabolism of the glucose, fat, protein of organism.Therefore, the adsorption effect for improving adsorbent material is except in decontaminated water
One of organic pollutant and the effective way of contents of many kinds of heavy metal ion.
The heavy metal-polluted method for treating water of tradition, which only passes through, reduces heavy metals concentration, and calcium hydroxide and flocculant is added certainly
So sedimentation, is finally discharged, and this method has the shortcomings that time-consuming, solid slag can not be handled, processing cost is high, processing is incomplete.
To in the processing of pollutant, absorption method due to its easy, efficient, economic, renewable, without secondary pollution the features such as increasingly by
The attention of people.The common active charcoal of adsorbent, silica gel, activated alumina, molecular sieve etc., wherein silica gel, molecular sieve price
Higher, activated alumina treatment effeciency is insufficient, although active carbon adsorption effect is good, it can be difficult to recycling and reusing, at the same time,
The absorption object of single adsorbent is excessively single, has been unable to meet treatment of Organic Wastewater demand at this stage, and it is efficient, honest and clean to be badly in need of research and development
Valence, environmental protection, good novel waste water adsorbent material.
Summary of the invention
The object of the invention is to remedy the disadvantages of known techniques, provides a kind of wastewater treatment adsorbent material and its preparation
Method.
In order to achieve the above purpose, the present invention the following technical schemes are provided:

Native 26 parts, 15 parts of bentonite, 11 parts of calcium hydroxide, 7 parts of active carbon, 18 parts of adsorbent, 2 parts of binder, 1 part of promotor.
The charcoal the preparation method comprises the following steps: crushed after straw is dried, be sent into the high temperature furnace of sealing, with nitrogen
It as reaction gas, is pyrolyzed 3-6 hours at 400-600 DEG C, is collected after cooling and obtain charcoal.
The preparation method of the adsorbent the following steps are included:
(1) it takes ferrous sulfate and manganese sulfate mixed dissolution in ethylene glycol, hexadecane is added thereto again after mixing evenly
Base trimethylammonium bromide, until being uniformly dispersed；
(2) above-mentioned mixed liquor is kept the temperature 18-24 hours at 200-240 DEG C, be cooled to room temperature later, dried after cleaning
To adsorbent.
It is 2:1, cetyl three that wherein ferrous sulfate and manganese sulfate, which control iron ion and the molar ratio of manganese ion, after mixing
The additional amount of methyl bromide ammonium is 3-4 times of ferrous sulfate quality.
Any one or a few any ratio of the binder in hypromellose, sodium metasilicate, oxidized starch
The combination of example.
The promotor is stannous octoate and dibutyl tin dilaurate 1:(3-4 in mass ratio) it mixes.
The preparation method of above-mentioned wastewater treatment adsorbent material, comprising the following steps:
(1) charcoal, diatomite, bentonite are sent into pulverizer jointly, crushed 60-100 mesh, obtains mixed powder
It is spare；
(2) above-mentioned mixed powder and calcium hydroxide, active carbon, adsorbent are sent into high mixer jointly and are stirred and evenly mixed；
(3) by step 2 gained mixture investment double-screw extruding pelletizing machine hopper in, then thereto be added binder and
Promotor obtains adsorbent material of the present invention after extruding pelletization.
For the control of twin-screw extrusion temperature at 190-220 DEG C, screw speed is 250-300 revs/min in preparation method.
The invention has the advantages that
Waste water adsorbent material of the present invention is directed to its hole using natural materials such as charcoal, diatomite as absorption main body
The problem that diameter is more single, adsorption capacity is limited additionally adds adsorbent, uses solvent-thermal method in adsorbent preparation, reacts item
Part is mild, and process is simple, and using ferrous sulfate and manganese sulfate synthesizing magnetic metal oxide, shaggy structure is absorption
Material supplements more active adsorption sites, while can occur to move with the effect of externally-applied magnetic field and reunite, this spy
Property enables this adsorbent material be easy to recycle again in the treatment of waste water by magnetic separation technique, thus obtained adsorption material
Material can be good at the purification for being adapted to water body, especially for heavy metal pollution therein, be formed by absorption, recycling, regeneration
Using chain, water body purification cost is greatly reduced, there is considerable prospect of the application in the field of pollution control.
