The water restorative is montmorillonite clay modified by purifying sodium, acidification, column support and organic modification. And the purity, cation exchange, quantity, adsorption, interlaminar structure and interlaminar environment of montmorillonite after modification have been significantly improved. The removal of heavy metal ions and decolorization can be achieved by sodification. By acidification, the pore and pore structure are improved, the layer spacing is changed, and the impurities in the pores can be removed, and the pollutant molecules in organic wastewater can enter and adsorb. Through column brace modification, the specific surface area of montmorillonite is increased and the adsorption performance is improved. Through organic modification, the interlayer environment is changed, so that it changes from hydrophilic to hydrophobic, reducing surface energy; At the same time, the layer spacing and specific surface area after modification increased, and the ability to adsorb organic matter was enhanced.
Printing and dyeing wastewater, coking wastewater, inorganic wastewater, heavy metal wastewater, mineral processing wastewater, papermaking wastewater
The layer spacing is suitable, the specific surface area is large, the pore and void structure are rich, the dispersion and suspension are good, and the suitable interlayer environment is suitable for organic and inorganic environments.
Method of Application:
The weight ratio of montmorillonite to sewage is added to the sewage to be treated in a ratio of 0.1:1000~1:1000, stirred quickly for 5~20min, and then added flocculant, stirred for 5min, settled for 2~20min, and then carried out sludge separation or further microbial treatment.
