| 废纸造纸废水处理技术 Waste paper waste water treatment technology 一般废纸造纸废水的处理方法可分为物理法、化学法、物理化学法、生物法四类。由于其水质复杂, 通常采用将几种处理方法结合在一起的多级综合处理方法, 即对于不同污染特性的废水、在不同的处理阶段, 采取不同的处理技术。 The treatment method of waste paper waste water is divided into four categories: physical, chemical, physical and biological. Due to the complexity of the water quality, usually adopt several methods to comprehensive treatment method of multilevel together, that is, for different characteristics of waste water, in different stages of processing, adopt different processing technology. 2.1 废水初级处理方法 Primary treatment of wastewater 针对废水中含悬浮物较高的特点, 在处理废水时首先进行初级处理, 通常采用物理法, 辅以化学法。下面两种方法处理效果较好。 In the treatment of wastewater, it is characterized by high suspension, which is usually adopted by the physical method and the chemical method. The following two methods work better. 2.1.1 过滤 2.1.1 filter 过滤法是最简单的去除细小纤维的方法, 而且对其他处理设施起到保护作用。过滤通常采用细筛网或微滤机, 处理水量大时一般采用微滤机。由于过滤法不能去除油墨、溶解性物质以及过于细小的悬浮物, 所以只能作为预处理的手段 。 Filtering is the simplest way to remove small fibers and protects other processing facilities. The filter is usually used in fine mesh or microfilter, and the microfilter is used when the water is large. Because the filtration method does not remove ink, solubility and too small suspension, it can only be used as a pretreatment. |
