摘要
通过对稻壳进行阳离子化改性,制备了天然有机高分子絮凝剂(RHF)。采用疏浚底泥絮凝脱水的研究,评价了RHF的絮凝脱水效果。结果表明,RHF絮凝脱水效果比CPAM略差,优于PAFC,底泥絮凝脱水的同时,能有效去除水体污染物,改善余水水质。其中CPAM/RHF复配体系呈现出优良的絮凝脱水效果,可实现底泥的瞬间絮凝沉降脱水,且余水水质较好。
The natural polymer flocculeut（RHF） is prepared by cationic modified rice husk, a kind of agricultural waste. The effect of floceulation dehydration on dredged sludge by RHF is e- valuated by many a flocculation experiment. The results indicated that RHF not only play a positive role in dehydration, but also can remove water pollutants effectively. Besides, it could be found that the effect of floceulation dewatering by RHF is worse than CPAM, but better than PAFC. Above all, the CPAM/RHF complex system enabled dredged sludge to flocculate dewatering in a very short time with the promotion of water quality, It exhibits an excellent synergistic performance.
