- 摘要:
- 生活垃圾焚烧厂的渗滤液经膜深度处理后，产生的膜浓缩液中含有高浓度的难生物降解有机物、成分复杂的盐分和重金属，处置不当会造成严重的环境污染。针对膜浓缩液高盐分，尤其是氯离子浓度高的特点，进行了“混凝沉淀+纳滤+电解”组合工艺制备含氯消毒剂的研究。结果表明，该组合工艺可以回收70%~80%的膜浓缩液，并将其制备成有效氯含量约为0.40%的消毒剂；同时，对COD和总硬度（以CaCO3计）的去除率分别可达99.35%、78.43%。该工艺能够实现膜浓缩液的回收利用，所制备的消毒剂可用于厂区敞开式循环冷却水消毒。
- Abstract:
- The leachate membrane concentrate from a domestic waste incineration plant, which is produced by the nanofiltration/reverse osmosis process, is a kind of wastewater containing high concentration of non-biodegradable organic matter, complex salts, and heavy metals. Considering the high salinity of the membrane concentrate, particularly the elevated concentration of chloride ions, we conducted a study on producing chlorine-containing disinfectant through the integrated process of “coagulation and precipitation + nanofiltration+ electrolysis”. The results showed that 70%-80% of the membrane concentrate could be recovered by the combined process and prepared into a disinfectant containing 0.40% effective chlorine. The removal rates of COD and total hardness (expressed in terms of CaCO3) were 99.35% and 78.43%, respectively. This process can facilitate the recycling of membrane concentrate and the disinfectant can be utilized for treating the open circulating cooling water in the plant.
