Abstract
In order to solve the highway engineering structure foundation construction in the rapid dewatering of wastewa-ter,in this paper,a series of tube sedimentation tests were carried out to study the flocculation settlement ef-fect of waste slurry with different kinds of flocculants and different dosages.The results show that adding or-ganic flocculant can significantly accelerate the solid-phase flocculation rate of engineering waste slurry,and the thickness of flocculation deposit layer of engineering waste slurry caused by adding inorganic flocculant is relatively smaller than that of organic flocculant in the same time.The residual turbidity of waste slurry can be reduced to 10 FTU by adding 0.02%flocculant,which can effectively encapsulate and bridge solid particles.The flocculation effect of the flocculant is better than that of anionic Polyacrylamide(Apam),the dewatering effect was similar to that of composite flocculant(CaCl2+AMAP).关键词
