摘要
近年来,中国工业污水排放量呈下降趋势,但由于整体基数较为庞大,深挖工业污水排放量消减潜力,力争实现污水零排放具有重要研究价值。通过对厦门市284家实施污水零排放的企业进行调研,比较各行业的万元工业产值新鲜用水量、 COD及氨氮的万元工业产值产生量,并利用情景分析法预测2025年各行业污水零排放潜力。结果表明:2019年纸制品加工行业、食品加工行业、化纤织造加工行业的万元工业产值COD产生量大于其他行业,纸制品加工行业、化纤织造加工行业的万元工业产值氨氮产生量大于其他行业,表明这些行业污水零排放的潜力较大。根据情景分析法中高方案的预测,2025年重点行业的COD和氨氮的产生量预计比2019年分别减少81.59%和26.86%,表明该方案下更有利于行业实现污水零排放。
In recent years, China’s industrial sewage discharge has shown a downward trend, but due to its large overall base, it is of great research value to deeply tap the potential of industrial sewage discharge reduction and strive to achieve zero discharge.In this paper, through a survey of 284 enterprises in Xiamen that implemented zero sewage discharge, the amount of fresh water consumption, COD and ammonia nitrogen per ten thousand yuan of industrial output value of each industry was compared, and the scenario analysis method was used to predict the zero sewage discharge potential of each industry in 2025. The results showed that the production amount of COD per ten thousand yuan of industrial output value of the paper product industry, food processing industry and chemical fiber weaving and processing industry in 2019 were more than those of other industries, as well as that the production amount of ammonia nitrogen of the paper product industry and chemical fiber weaving and processing industry in 2019were more than those of other industries, which indicated that these industries had great potential for zero discharge of sewage.According to the high scheme of scenario analysis predicted that the production of COD and ammonia nitrogen in key industries in 2025 was expected to decrease by 81.59% and 26.86% respectively compared with 2019, which indicated that this scheme was more conducive to the industries to achieve zero discharge of sewage.
