水下航行器舱室内废水处理及回用研究

摘要

为解决水下航行器舱室内用水需求困难，针对废水水质建立了膜分离废水处理及回用系统，研究了该系统对废水的处理性能及出水回用性能．实验废水为模拟的水下航行器收集到的废水，结果表明，尽管系统进水水质、流量变化较大，但经系统各级处理后，浊度和阴离子洗涤剂（ LAS）去除率为100％，COD和氨氮（NH3-N）去除率可达99．9％，出水水质达到回用标准．%In order to resolve the problem of water supply in cabin of underwater vehicle , this paper established the wastewater disposal and reuse system by integrated membrane process according to the wastewater quality .Using simulated wastewater as substrate , the perform-ance of wastewater disposal and reuse was investigated .It is found that though the wastewater quality and flow varied sharply , the system effluent quality met the reuse standard .The tur-bidity and LAS could be removed entirely and the removal efficiency of COD and NH 3-N could achieve high level of 99.9%.
