Abstract
The invention relates to a wastewater processing absorbent and a preparation method thereof. The absorbent comprises 30-50% of cement hydrate, 30-40% of palygorskite, and balance of bentonite. The preparation method comprises steps that: powdery materials are uniformly mixed into a wet and moldable form; the obtained material is extruded into a blank by using a mold; and the blank is subject to heat treatment for half an hour under a temperature of 100-250 DEG C. The raw materials provided by the invention have low prices and wide sources. The cement hydrate has an excellent phosphorous-absorbing characteristic. Bentonite and palygorskite have unique porous structures, such that the absorbing characteristics of bentonite and palygorskite are substantial. Because the material has a wet-state molding capacity, processing absorbents with different shapes can be prepared according to different requirements. The absorbent obtained after heat treatment has relatively high strength, and is easy to recycle.
Description
Technical field
The present invention relates to a kind of wastewater treatment adsorbent and preparation method thereof, belong to water treatment field.
Background technology
In the modern industry life, inevitably produce a lot of waste water and gas, human also increasingly high to environment requirement, the research topic that is treated as a hot topic of waste water.Contain a large amount of phosphorus, organic dyestuff, heavy metal etc. in the waste water.
Summary of the invention
The present invention is directed to prior art, provide a kind of with low cost, the significant wastewater treatment adsorbent of adsorption effect.
The present invention realizes through following technical scheme:
A kind of wastewater treatment adsorbent comprises cement-hydrate 30-50%, and palygorskite 30-40% surplus is a bentonite.
Said wastewater treatment adsorbent, said cement-hydrate 40%, palygorskite 35% surplus is a bentonite.
Said wastewater treatment adsorbent, said cement-hydrate is concrete, screening, obtains the particle of 1-25mm.
Said preparation of adsorbent method, it is plastic that powder evenly is mixed to hygrometric state; Be squeezed into blank with mould then; Again with blank 100-250 ℃ of heat treatment half an hour.
Beneficial effect of the present invention is: the prices of raw and semifnished materials of the present invention are cheap, and the source is abundant, and cement compound has excellent characterization of adsorption to phosphorus; Bentonite and palygorskite have unique pore structure, and characterization of adsorption is remarkable, because it has the hygrometric state forming ability, can prepare difform processing adsorbent according to demand; Adsorbent after the heat treatment has higher intensity, is easy to recycle.
The specific embodiment
Non-limiting example is implemented as follows.
Embodiment 1: cement-hydrate 30%, palygorskite 30% surplus is a bentonite.It is plastic that powder evenly is mixed to hygrometric state; Be squeezed into blank with mould then; Again with blank 100-250 ℃ of heat treatment half an hour.
Embodiment 2: mud hyrate 40% palygorskite 40% surplus is a bentonite.It is plastic that powder evenly is mixed to hygrometric state; Be squeezed into blank with mould then; Again with blank 100-250 ℃ of heat treatment half an hour.
Embodiment 3: mud hyrate 50%, palygorskite 35 surpluses are bentonite.It is plastic that powder evenly is mixed to hygrometric state; Be squeezed into blank with mould then; Again with blank 100-250 ℃ of heat treatment half an hour.
Cement-hydrate of the present invention is discarded concrete system in the building; Palygorskite has rich in natural resources within the border in Jiangsu, price is also cheap, and bentonite also is cheap raw material; But, has stronger characterization of adsorption because it has special poroid micromechanism.
