摘要:我国化学机械浆产能迅速扩张，填补了“限废令”执行所造成的再生纤维缺口。水环境容量属于可再生的自然资源，也是产业发展的关键约束性条件，造纸工业发展需要水环境容量作为支撑，以消纳废水排放的潜在环境影响。本文回顾了末端污染控制对削减行业污染物排放的支撑作用，探讨了国内纸浆产能提升面临的水环境容量限制，主张降低单位产品水耗是持续削减造纸工业环境影响的必经之路，提出了制定造纸工业水再生利用导则的必要性，总结了清洁化生产与中水再生利用的可行技术，以期为推动造纸工业可持续发展提供参考。

Abstract:The rapid expansion of China’s chemical mechanical pulp production capacity has filled the gap of recycled fiber resulting from the implementation of the “waste restriction order”. Water environmental capacity is a renewable natural resource that restricts the development of papermaking industry. The development of papermaking industry requires water environmental capacity to mitigate the potential environmental impacts of wastewater discharge. This paper reviewed the contribution of wastewater treatment in reducing pollutant discharge. The water environmental capacity limitations faced by the improvement of domestic pulp production capacity were mentioned to propose that reducing water consumption per unit product was a necessary way to continuously minimize the environmental impact of papermainy industry. Besides， the necessity of establishing guidelines for water recycling in the paper industry was advocated， while the feasible technologies for clean production and water recycling were summarized. In order to provide a reference for promoting the sustainable development of papermaking industry.
