Study on Preparation of Flocculant in Low-Temperature Wastewater

Abstract:

This paper mainly investigate how to use cheaply-priced, safety and sanitate of natural clay or nanosilica as coagulant and adsorbent combined with polyaluminium chloride to treat low temperature and low turbidity water .Wastewater in paper mill was used as the water samples, by measuring the absorbance and the turbidity of the water samples to determine the flocculation effect. The results showed that flocculation effect of water samples with different natural clay and nanoSiO₂ combined with PAC had the same change tendency. The order of coagulation effects was bentonite > diatomite > kaolin > attapulgite. nano-SiO₂ as coagulant associated with PAC could attain best coagulation effect with least amount from the analysis of absorbance or turbidity.
