泥浆快速化学脱稳与固液分离试验研究
Experime ntalr esearch on rapid chemical destabilization and solid-liqui d es paration of slurry
摘要
Abstract
In view of the fact that the slurry with high water content is hard to be dewatered rapdily which slows down the progress of construction , experiments were designed to get the rate of the solid-liquid separation of slurry at different periods .Various impacts of the different kinds and dosages of flocculants and different additives on the rapid solid-liquid separation were studied .After getting the optimal dosage of flocculants , different additives , such as cement , fly ash and water reducer were added to verify their intermixing effects with the flocculants .Experimen-tal results show that:macromolecular polyethylene vinyl silane has the best effect among the four flocculants and its optimal dosage is 0.018%of the mass of the slurry;the cement has a positive intermixing effect and its optimal dos-age is 1%of the total mass , and the best adding order is:cement ,water reducer , and then flocculants .关键词
