Description
Technical field
The invention belongs to water-treatment technology field, particularly relate to a kind of water eutrophication ion attapulgite adsorbent.
Background technology
Body eutrophication refer to due to the elements such as substantial amounts of nitrogen, phosphorus, potassium be drained into flow velocity slowly, the ground of update cycle length
Table water body, makes the aquatiles such as algae growth and breeding in large quantities, makes the speed that Organic substance produces considerably beyond depletion rate, water body
Middle Organic substance is put aside, and destroys the process of aquatic ecological balance.
Eutrophication can affect the water quality of water body, the transparency of water can be caused to reduce so that sunlight is difficult to penetrate water layer, from
And affect the photosynthesis of aquatic plant, it is likely to result in the hypersaturated state of dissolved oxygen.In the supersaturation of dissolved oxygen and water molten
Solution oxygen is few, is all harmful to aquatic animal, causes Fish mortality.Meanwhile, because body eutrophication, water surface grows
A large amount of algaes with cyanophyceae, chlorella as sociales, form one layer " green scum silica frost ", cause the organic substance that bottom is piled up in anaerobism
Condition decomposes the biotoxin of the harmful gas produced and the generation of some planktons also can injure Fish.Because of in eutrophic water
Containing NO3-N and NO2-N, these content of material of people and animals' long-term drink exceed the water of certain standard, also can be poisoned pathogenic.
Process at present this kind of poisonous, adsorption treatment method that bio-refractory waste water technique mainly has physics, traditional suction
Attached dose of main active charcoal, adsorbance is big, processes the cycle short, and selectivity is little, but price is high, and the required energy consumption of regeneration is big, it is difficult to
Regeneration cycle uses；Adsorb the activated carbon treatment effeciency of eutrophy ion in water body low, it is difficult to regeneration cycle uses, produce two
Secondary pollution.
Summary of the invention
It is an object of the invention to provide a kind of water eutrophication ion attapulgite adsorbent, by using attapulgite to glue
Soil and meerschaum are primary raw material, and its preparation method has a function of catalyzing oxidized regeneration adsorbent, not only at high temperature gas flow and
Under air, the degradation rate to hazard biological hardly degraded organic substance is higher, and repetitive cycling uses, owing to catalytic action also reduces
With temperature and time required when decreasing oxidizing process, save energy consumption, reduce cost, solve existing adsorbent and produce
Cost is high, can not regeneration cycle uses and adsorbent self does not possess catalytic capability problem.
For solving above-mentioned technical problem, the present invention is achieved by the following technical solutions:
The present invention is a kind of water eutrophication ion attapulgite adsorbent, and described attapulgite adsorbent includes following weight ratio
The raw material of example: attapulgite clay 40%～70%, meerschaum 30%～60%；
This attapulgite adsorbent is prepared by following steps:
(1) attapulgite clay and meerschaum are carried out high temperature modified；
(2) attapulgite clay after high temperature modified and meerschaum are joined the mixed solution of cobalt nitrate and ferric nitrate
In, the pH value of regulation mixed solution is 1～2, and then 12h is put in leaching；
(3) attapulgite clay and meerschaum are repeatedly rinsed after end is put in leaching with distilled water colourless to solution；
(4) will calcine in Muffle furnace more than 1 hour through the attapulgite clay after step (3) processes and meerschaum,
Take out cooling, i.e. prepare adsorbent finished product.
Further, described attapulgite adsorbent includes the raw material of following part by weight: attapulgite clay 55%, Hai Pao
Stone 45%.
Further, described cobalt nitrate and ferric nitrate mol ratio are 2: 1.
Further, the pH value of described regulation mixed solution is 2.
Further, described in Muffle furnace at 500 DEG C～600 DEG C calcine 3h.
The method have the advantages that
Preparation technology of the present invention is simple, low cost；Repetitive cycling uses, and abandons, after reducing adsorbent, the secondary caused
Pollute, save energy consumption, reduce cost.Simultaneously because used carrier attapulgite clay and meerschaum itself have good rheology
Property, the excellent properties such as heat stability, dispersibility and mechanical strength, provide new for processing of hazard biological organic wastewater with difficult degradation thereby
Environment-friendly materials.
Certainly, the arbitrary product implementing the present invention it is not absolutely required to reach all the above advantage simultaneously.
