Technical Field
The invention belongs to the technical field of adsorbents, and particularly relates to a preparation method of a desorption-free adsorbent with a large-particle trepanning structure.
Background
In recent years, with the environmental protection awareness, the work of efficiently treating industrial wastewater is compelling. The adsorption method is capable of removing pollutants without damaging the pollutants, and only accumulates the pollutants on the adsorbent from the polluted water body, so that high-risk intermediate products are not generated. The surface structure of the adsorbent, the molecular structure of the adsorbate, the properties of functional groups, and the like are main factors influencing the adsorption rate, and in conclusion, the research and development of the general adsorbent and the renewable adsorbent are the key points of the application of the adsorption technology. The adsorbent commonly used in the current engineering practice is mainly inorganic adsorption material and organic adsorption resin. The inorganic adsorption material has considerable specific surface area and ultramicro capillary, and has wide application, low price, slow adsorption rate and poor regenerability; the organic adsorption resin has large adsorption capacity and good reproducibility, but the organic adsorption resin has high price, strong selectivity and narrow application range. Therefore, the development of the adsorption material which has wide application range, high adsorption capacity, good reproducibility and moderate price has important significance for green emission of factory wastewater.
Although some researchers have improved the defects of slow adsorption rate and poor regenerability of the inorganic adsorbent and some researchers have adjusted the application range of the adsorbent resin, the regenerable inorganic adsorbent still has the problems of poor regenerability, low adsorption capacity and the like, and the cost of wastewater treatment cannot be reduced due to the limitation of synthetic raw materials of the organic adsorbent resin and the high price.

In order to achieve the purpose, the invention adopts the technical scheme that: a preparation method of a desorption-free adsorbent with a large-particle trepanning structure comprises the following steps in parts by weight:

2) weighing 0.7-7 parts of inorganic adsorbent component, and adding sulfuric acid with the amount exceeding that of the solid component for ultrasonic activation for 30 min;
3) weighing 2-8.5 parts of colloid, adding deionized water according to the proportion of 1: 1-1: 20 to prepare a solution, uniformly mixing the activated products prepared in the step 1) and the step 2), adding the activated products into a mixed solution of the colloid and water, uniformly stirring, and ultrasonically blending for 2 hours;
4) and adjusting the ph to be neutral, adding 2-10 parts of cultured thalli, uniformly stirring, pouring into a mold for granulation, and drying at low temperature to obtain the porous adsorbing material.
The macroporous ion exchange resin is any one or mixture of more commercially available macroporous ion exchange resins;
the inorganic adsorbent is one or the combination of any more of active carbon, kaolin, attapulgite, zeolite and diatomite.
The colloid is one or a mixture of any more of polyvinyl alcohol, carboxymethyl cellulose, pure acrylic emulsion, styrene-acrylic emulsion, silicone-acrylic emulsion and VAE emulsion.
