摘要:
义乌市某工业水厂出水水质较差，用水端反渗透膜堵塞频繁。基于此，提出了近期结合远期的改造运行方案，以延长膜堵塞周期。通过分析膜堵塞物的元素成分，发现有机物的主要元素C、O、N、P的占比分别为35.62%、32.64%、27.08%、0.76%，四种元素总占比高达96.10%，因此有机物是膜堵塞的主要原因。近期方案使用活性炭结合曝气生物滤池的联合工艺，总有机碳（TOC）去除率可达33.85%。远期方案增加预臭氧-活性炭-后臭氧（沉后）-活性炭工艺，TOC去除率可进一步提高至50%左右。该方案综合了近期与远期的运行策略，既满足了应急处理的需求，又达到了长期稳定运行的目标，可为实际工程中其他工业水厂出现类似现象提供技术经验。
Abstract:
The effluent quality of an industrial water plant in Yiwu City is substandard, and the reverse osmosis membrane at the water end is clogged frequently. On this basis, the paper proposed a short-term combined with long-term operation plan to prolong the membrane fouling period. By analyzing the elemental composition of the membrane-fouling material, it was discovered that the main elements of organic matter, namely C, O, N, and P, accounted for 35.62%, 32.64%, 27.08%, and 0.76% respectively, and the total proportion of these four elements was as high as 96.10%. Therefore, organic matter was the primary cause of membrane fouling. In the short-term operation plan, the combined process of activated carbon and biological aerated filter was employed, and the removal efficiency of TOC reached 33.85%. In the long-term operation plan, the process of pre-ozonation-activated carbon-post-ozonation (post- precipitation) -activated carbon was incorporated, and the TOC removal efficiency could be further elevated to approximately 50%. This plan integrated the short-term and long-term operational strategies, not only fulfilling the requirements of emergency treatment but also attaining the objective of long-term stable operation, which could offer technical experience for other industrial water plants with similar phenomena in actual projects.
