摘要:
针对反渗透技术处理垃圾渗滤液过程中产生的反渗透浓缩液（LLROC），采用套管式气隙膜蒸馏组件（DP-AGMD-M）对其进行浓缩处理，探究温度、流量等工艺参数对DP-AGMD-M性能的影响，考察深度浓缩过程中DP-AGMD-M对污染物的截留能力，并评估生活垃圾焚烧余热驱动DP-AGMD-M的可行性。结果表明，在所考察的工艺参数中，料液温度对组件性能影响最大，当料液温度为90 ℃时，膜通量、造水比及热效率的最高值分别可达到1.95 kg/（m2·h）、0.24和20.8%。在LLROC深度浓缩过程中，DP-AGMD-M的膜通量较为稳定，未出现膜污染现象。当将LLROC浓缩5倍时，DP-AGMD-M对除氨氮外的其他污染物的截留率均超过99%。余热利用可行性分析表明，垃圾焚烧厂余热可满足DP-AGMD-M系统现场处理需求。可见，DP-AGMD-M能够应用于LLROC深度浓缩处理领域，且具备利用低品位热源的工程化应用潜力。
Abstract:
To address the reverse osmosis concentrate (LLROC) generated from the treatment of landfill leachate by reverse osmosis technology, a double-pipe air gap membrane distillation module (DP-AGMD-M) was employed for its further concentration. The effects of process parameters, including temperature and flow rate, on the performance of the DP-AGMD-M were investigated. The rejection capacity of the DP-AGMD-M for various pollutants during the deep concentration process was examined, and the feasibility of driving the DP-AGMD-M using waste heat from municipal solid waste incineration was evaluated. The results indicated that among the parameters studied, feed temperature exerted the most significant influence on module performance. When the feed temperature was 90 ℃, the maximum membrane flux, gained output ratio (GOR), and thermal efficiency reached 1.95 kg/(m2·h), 0.24, and 20.8%, respectively. During the deep concentration of LLROC, the membrane flux of the DP-AGMD-M remained relatively stable, with no observable membrane fouling. When the LLROC was concentrated to one-fifth of its original volume, the DP-AGMD-M achieved over 99% rejection for all pollutants except ammonia nitrogen. The feasibility analysis of waste heat utilization demonstrated that the waste heat from the incineration plant could satisfy the on-site treatment requirements of the DP-AGMD-M system. Overall, the DP-AGMD-M shows promising applicability for the deep concentration of LLROC and possesses significant potential for engineering implementation powered by low-grade heat sources.
