Description
Technical field
The present invention relates to a kind of preparation method of Vermiculitum/activated carbon base water treatment agent, belong to adsorption functional material and water treatment field.
Background technology
Semi-coke industry is one of Yulin City pillar industry, accounts for the 2/3 of national semi-coke production, is the important component part of Yulin City coal poly-generation and industrial economy.But, semi-coke will produce the semi-coke wastewater of high concentration, high COD, high ammonia nitrogen, difficult for biological degradation in retort process, semi-coke wastewater is the high-concentration waste water of high poison high pollution, and its major pollutant is similar to coking chemical waste water, is phenols, cyanide, heterocyclic aromatic hydrocarbon and ammonia nitrogen etc..Ammonia nitrogen pollutant is upright to be met outer row and can make algal bloom, the great minimizing of oxygen in water, leads to body eutrophication, and the too low blood that can also result in aquatic organism of oxygen in water combines oxygen ability and declines, if ammonia nitrogen concentration is excessive in water, aquatic organism can be directly resulted in dead.If heterocyclic material directly outer row also can consume oxygen in water so as to dissolved oxygen reduce, concentration very conference makes the microorganism in water be difficult to survive and so that water body is degenerated.Cyanide belongs to hypertoxicity material.Outer row may result in people, aquatic organism and vegetation to be poisoned to death.Therefore, semi-coke wastewater has very big hazardness to the mankind, water body and vegetation.
In recent years, adsorption technology is because being used for the features such as it is cheap, efficient and easily separated processing industrial wastewater.The principle of absorption method be using adsorbent adsorptivity by the Adsorption of Organic in waste water in its duct.When adsorption saturation, then adsorbent is desorbed, removes the Organic substance in duct, to recycle.The conventional active charcoal of adsorbent, resin, zeolite, sulfonated coal, bentonite etc. at present.Resin has the advantages that porosity is high, adsorption capacity is big, high mechanical strength, and it has stronger absorbability to phenols, therefore, domestic adopts resin adsorption method more.The advantage of absorption method is effect stability, process is simple, non-secondary pollution, but because adsorbent aperture is small, clogging easily, limits its industrial applications the shortcomings of regeneration cost is big.
Content of the invention
It is an object of the invention to provide a kind of adsorption capacity is big, the preparation method of the repeatable Vermiculitum/activated carbon base water treatment agent utilizing.
The present invention to implement process as follows：
A kind of preparation method of Vermiculitum/activated carbon base water treatment agent, Vermiculitum is pressed 1 with tar slag:1~5:1 mixing, first completely cuts off air in 500 ~ 800 DEG C of calcination processing, then processes through carbon dioxide activation at 500 ~ 1000 DEG C and obtain Vermiculitum/activated carbon base water treatment agent.
Above-mentioned Vermiculitum is expanded vermiculite；The above-mentioned calcination processing time is 0.5 ~ 2 hour, and carbon dioxide activation process time is 0.5 ~ 1 hour.
The Vermiculitum that above-mentioned preparation method prepares/activated carbon base water treatment agent can be applicable to process semi-coke wastewater, and when specifically used, after Vermiculitum/activated carbon base water treatment agent absorption waste water, drying, calcining, activation are circulated utilization again.
Advantages of the present invention and good effect：（1）Raw material is easy to get, preparation method is simple；（2）Reusable after prepared Vermiculitum/activated carbon base water treatment agent is activated, and effect is more excellent.
