摘要: 经深入研究, 确定华北制药厂丙丁废醪厌氧-好氧处理过程中产生的白色结晶物为磷酸铵镁, 其堵塞管道, 影响生产.从理论和工艺技术上有针对性地提出了几种解决途径, 由此, 不仅可以克服堵塞管道的弊端, 而且可以使其得到有效利用, 变废为宝.Abstract: The research shows that the white crystal that arises from the anaerobic oxic treatment of acetone and butanol's wastewater in North China Medicine Factory is determined to be MgNH4PO4 which blocks up the pipelines and reduces the production. Several kinds of approaches are presented in terms of theoretical analysis and techniques not only to overcome the disadvantages of blocking up pipelines by MgNH 4PO 4, but also to make efficient use of these waste materials.
