摘要:
喷水织机用水量大，对水质要求高，对废水进行处理后回用有助于缓解区域水资源矛盾，降低织机用水成本。本文分析了喷水织机废水的来源、解析了水质组成特征，发现废水中79.4%的有机污染物以悬浮态和胶体态存在；通过对比废水和用水关键水质指标差异，明确了处理回用的主要目标是SS、COD和离子物质；针对不同的目标污染因子分类总结了的现有处理技术的应用情况及存在的问题；对喷水织机废水处理回用技术的研究方向提出了展望。Hydraulic loom consumes a lot of high quality water, which makes it necessary to treat and reuse the wastewater for the purpose of mollifying regional water resources contradiction and saving water cost. The sources and the composition of the hydraulic wastewater were analyzed in this paper and it was found that the sum of suspending solids and colloidal substances accounted for 79.4% of the total organics. Then the differences between water and wastewater indexes value in-dicate that the main pollution factors are SS, COD and ionic substances. After that, the available hydraulic wastewater treatment technologies were classified, compared and reviewed according to their functions and problems. Finally, the probable research directions were forecasted.
