摘要
R2S型反应器能降低废水的化学耗氧量和产生沼气,同时过程中产生的去钙离子水可供造纸生产重复利用
去年12月,SCA Lucca公司启用了一台厌氧反应器,该公司年产33万吨回收箱板纸,是意大利最大的瓦楞原纸厂。生试用阶段,这台反应器使纸厂废水的COD下降了80%。Lucca反应器是这类产品的代表,该技术最初是应用于饮食业,后来经Voith和废水处理专家Aquatyx公司改造后用于造纸废水处理。
The R2S reactor reduces chemical oxygen demand, generates biogas and produces calcium-free water for re-use in the papermaking process An anaerobic reactor started up last December at SCA Lucca, a 330,000tpy recycled containerboard mill and Italy's largest producer of corrugated case materials (CCM). During the start-up phase, the reactor achieved an 80 per cent reduction in the level of chemical oxygen demand (COD) of the mill's wastewater.
