摘要:
水母暴发对海水淡化厂的运维管理造成诸多挑战。基于10万m3/d双膜法海水淡化项目，分析了海月水母暴发后设备故障项词频分布、工艺电耗和药耗以及超滤和反渗透膜系统跨膜压差的变化，以揭示水母暴发对海水淡化项目运行的影响，并提出防控策略。研究结果表明，在水母暴发期间，海水淡化厂的设备故障集中于超滤系统的玻璃钢管道（尤其是三通部位）和阀门，表现为漏水与腐蚀；建议在水母暴发前进行管道加固和修补。水母暴发导致超滤化学清洗电耗增加75.0%，超滤和反渗透化学清洗电耗分别增长28.1%、14.5%。超滤清洗药剂次氯酸钠和氢氧化钠投加量分别增加6.7%和25.6%，药单耗分别增加18.2%和13.4%；反渗透杀菌剂投加量提高323.6%，药单耗提高207.4%。通过优化超滤运行时间及增加反冲洗和化学清洗频次，可有效控制超滤跨膜压差；增加化学清洗对反渗透跨膜压差控制的效果有限，需进一步排查超滤与反渗透之间的污染源。该研究为水母暴发期海水淡化厂的运行和防控提供了参考和依据。
Abstract:
Jellyfish blooms significantly compromise the operational efficiency of seawater desalination plants. This study investigates a dual?membrane desalination system with the scale of 10×104 m3/d, analyzing the term frequency distribution of equipment failure items, electricity/chemical consumption, and the variation of transmembrane pressure (TMP) in ultrafiltration(UF) and reverse osmosis(RO) systems after Aurelia aurita outbreaks, with the aim of revealing the impacts of jellyfish blooms on desalination plant and proposing prevention and control strategies. Key findings indicate that bloom events primarily affect UF systems, with equipment failures occurring in FRP pipes (especially discharge pipeline T-joints) and valves, predominantly through leakage and corrosion mechanisms—highlighting the importance of preventive maintenance. The research quantifies substantial operational impacts: UF chemical cleaning electricity consumption surges by 75.0%, while UF and RO chemical cleaning experience 28.1% and 14.5% higher electricity requirements, respectively. Chemical consumption patterns reveal even more dramatic effects, with UF cleaning agents (NaClO and NaOH) showing dosage increases of 6.7% and 25.6%, respectively, with unit consumption increasing by 18.2% and 13.4%, respectively. Most strikingly, RO biocide requirements escalate by 323.6% (dosage) and 207.4% (unit consumption). Operational optimization demonstrates that adjusting UF cycles and intensifying cleaning protocols effectively manages TMP, whereas RO systems show limited responsiveness to chemical cleaning—suggesting cross-process contamination as a critical research focus. These evidence?based insights offer practical solutions for desalination plant management during jellyfish proliferation periods.
