国内外废纸造纸废水零排放工艺研究及运行实例

废纸造纸废水零排放可以大量降低新鲜水用量，避免废水排放和节约废水处理成本，但是采用全封闭存在系统腐蚀、会产生有气味化合物、增加腐浆生成、降低留着率、生成沉淀、引起运行故障、降低产品质量等风险。在此以国内外废纸造纸企业废水零排放运行实例，研究其工艺特点及水质参数，为废纸造纸企业提供稳定和经济的废水零排放技术，最终实现节能、减排、增效的目标。

Process Research and Engineering Application about Zero-Discharge of Wastewater from Regenerated Papermaking in the World

Zero-discharge of wastewater from regenerated papermaking can decrease pure water expense, wastewater discharge and wastewater disposal costs. But the risk such as equipments corrosion, odor, slime pulp increase, retention rate decrease, precipitate, operation troubles, and product quality will occur due to the closed circulation. Based on the engineering application in the world, technology characteristics and parameters are researched, which provides zero-discharge techniques of wastewater for the regener...
