摘要
结合制浆造纸废水处理的工程实践,对制浆造纸废水的来源、特性和设计废水处理工艺时应注意的问题进行总结。在选择制浆造纸废水处理工艺时,需要全面了解废水的来源、制浆造纸工艺等相关内容,根据不同工艺所得吨浆(纸)的污染物负荷,选择合适的处理流程;在废水处理过程中,要合理控制反应温度、pH值、预酸化度、营养物的投加比例等参数。不能简单照搬其他行业废水的处理工艺,需结合和借鉴其他制浆造纸企业相近的废水处理工艺,设计合理的方案。
Based on the engineering experience of pulping papermaking effluent treatment,it is suggested that the treatment technology selection must consider the source of the effluent,the pulping and papermaking process used,and the pollutant load per unit product.Meanwhile the treatment parameters such as reaction temperature,pH value,pre-acidation,nutrient dosage must be controlled reasonably.Be careful to simply copy other effluent treatment technology,instead,the effluent treatment scheme must be designed properly based on other paper mills experiences where the similar effluent was treated.
