摘要:介绍了一种新型的制浆造纸过程水处理系统VoxSton, 该系统由2个离心分离器、1个螺旋分离器和2个涡流浮选单元组成。该过程水处理系统可以将污泥中的纤维等固形物分离,并将其压缩至高达30％的固含量,对废水进行清洁处理后回收或排放。该处理系统在大多数情况下,可以直接在排污口对污泥进行连续或每日间歇式处理,而不需要均衡和预沉淀处理。该过程水处理系统的目标是循环利用工艺水,并尽可能地收集不同的可再利用成分。与现有的水处理系统相比,该过程水处理系统在节约能耗和占地面积的同时,还可以节约50％左右的运行成本,且投资成本更低。

Abstract:A new industrial process water treatment system is presented in this paper. The system consists of two centrifugal separators, a screw separator and two vortex flow flotation units. It can separate the solids like fibers out from the sludge and press them to dry matter content of up to 30 percent and clean the sludge water for recycling or discharge to nature. The treatment system can in the most cases treat process sludge continuously or daily basis directly from the process outlet without equalization and precipitation. The objective using thin system is to recycle the process water and collect different ingredients for reuse as much as possible. The system saves energy and space as well as operational costs roughly 50 percent compared to present advanced systems. The capital costs are estimated to be lower too．
