自2011年7月1日起,废水排放指标更加严格:废水深度处理迫在眉睫

Advanced treatment for waste water is extremely urgent

为促进区域经济与环境协调发展，推动经济结构的调整和经济发展方式的转变，引导造纸工业生产工艺和污染治理技术的发展方向，我国在2008午8月1日起实施新的制浆造纸工业水污染排放标准（GB3544—2008）。

From July 1, 2011, the discharge limit in the second stage of Discharge Standard of Water Pollutants for Paper Industry GB3544-2008 will be implemented in the existing pulp and paper enterprises, which will be a severe challenge to the relative paper enterprises. The implementation of the second stage discharge limit will make the treatment with two-stage alone not reach the discharge standard, so the promotion of advanced treatment technologies for waste water is really urgent. Furthermore, the differences between the advanced treatment technologies for waste water in infrastructure investment, treating effect, running cost and secondary pollutant are very obvious because of the differences in raw materials, process facilities and products and so on. Therefore, CPPI will specially present a topic on advanced treatment technologies for waste water, in order to make the enterprises a comprehensive understanding for the present situation and development in advanced waste water treatment to help enterprises to plan earlier,take measures, less to avoid detours and to realize "green" sustainable development. The raletive experts, entrepreneurs, technicist are invited to summarize the main technologies and practical achievements for advanced waste water treatment from different aspects, to analyze and compare among different treatment methods on their merits and demerits. The new technologies and achievements from overseas applied to advanced treatment for waste water were also introduced. Three companies including MCC Paper Yinhe, Sun Paper and Nanning Phoenix which were chosen as the typical application cases will be reported on this issue. ·Advanced treatment technology and practice for modern pulp and paper wastewater ·Rethinking on new wastewater discharge standard after two years implementation ·Photocatalytic treatment of papermaking wastewater and process control system ·The supercritical water oxidation recycle management of pulping black liquor ·A outlook of constructed wetland system applied to advanced treatment for chemimechnical pulping wastewater ·New achievements of advanced oxidation technology applied to paper wastewate treatment ·Running practice of recycled water reuse in MCC Paper Yinhe ·The strategy and experience of Sun Paper for water saving and pollutant control ·Practice on waste water advanced treatment by coagulation in Phoenix Paper
