摘要

摘要: 电解锰行业废水产生点位多、成分复杂,各工序水污染负荷的系统的量化数据比较缺乏。通过调研占行业总产能85%的技术数据,确定了浸出氧化、压滤、电解及后续、渣场渗滤液和初期雨水5个源解析工序,化学需氧量、氨氮、总铬和总锰4个解析因子,对电解锰废水进行等标污染负荷源解析,以期为制定行业环境管理政策标准、指导技术研发方向及技术推广应用等提供基础数据和参考依据。结果表明:生产1 t锰的废水等标污染负荷为6 119.7,总锰、氨氮和总铬是主要污染物,累积负荷比达99.7%;电解及后续、渣场渗滤液和压滤工序是行业环境管理的重点工序,等标污染负荷比分别为47.2%、27.8%和22.6%,其中,渣场渗滤液具有较高的污染负荷,亟需重点关注;电解及后续工序是废水污染负荷最大、减排潜力最大的工序,也是技术研发的重点工序,针对该工序研发的清洁生产技术可大幅降低等标污染负荷。

Abstract: The wastewater with complicated compositions generated by the electrolytic manganese industry was from many processes, and the systematic quantitative data of the water pollution load in each process was relatively lacking. Through research on technical data that accounted for 85% of the industry’s total capacity, five source analysis processes including leaching oxidation, pressure filtration, electrolysis and subsequent sections, leachate from residue field and initial rainwater were determined, and four analytical factors including chemical oxygen demand, ammonia nitrogen, total chromium, and total manganese were also determined. The analysis results of pollution source apportionment provided important basic data and reference for formulating industrial environmental management policy standards, guiding the direction of technology research and development, and leading technology promotion and application.The equivalent pollution load source analysis results indicated that the equivalent pollution load of the wastewater from the production of one ton of manganese was 6 119.7. Total manganese, ammonia nitrogen and total chromium were the main pollutants, and the cumulative load ratio was 99.7%. The electrolysis and subsequent sections, leachate from residue field, and pressure filtration, with the equivalent pollution load ratio being 47.2%, 27.8% and 22.6%, respectively, were the key processes of the industrial environmental management. Meanwhile, it was discovered that the leachate from residue field had a higher pollution load, which needed urgent attention. The processes with the greatest water pollution load and emission reduction potential were electrolysis and subsequent sections, which were also the key processes of technology research and development, and the cleaner production technologies developed for these processes could significantly reduce the equivalent pollution load.
