【摘要】 以气浮和过滤为主导工艺,分别以纸机和制浆为中心的循序和循环供水系统,是行之有效的板纸废水治理及回用的实用技术。可节省自来水60～80％,并可使板纸废水的排放量相应减少60～80％而达标排放。城市污水净化厂的出水,可作为板纸生产工艺用水的水源而取代自来水。对板纸生产的发展及缓和城市供水紧张局面,具有重要的现实意义。更多还原

【Abstract】 It is a feasible and effective process for pulp and paperboard production wastewater treatment and reuse that floatation, filtration and sequential and circulation techniques are used in the paperboard production water supply system. The process can reduce 60-80% fresh water consumption, and consequently .reduce the same amount of wastewater discharged. The municipal sewage plant effluent can be used as the paperboard production water source. This will be of great practical important in paperboard production and ease the tension of city water supply shortage in china更多还原
