Abstract

Nowadays, performance studies on the amperometric total residual oxidant (TRO) sensor are only in the bench test stage and have not been conducted under specific maritime conditions with Ballast Water Management System (BWMS). In this study, the application of the amperometric TRO sensor in land-based biological efficacy (BE) testing, operation and maintenance (O&M) testing, as well as shipboard (SB) testing, was explored by comparing with the existing di-phenylene-diamine (DPD) TRO sensor. The results showed that the average TRO measurement deviation between the amperometric sensor and the DPD sensor was within ±10% in valid BE test cycles and the O&M testing exceeding 47 operating hours. The TRO value measured by amperometric sensor exhibited significant fluctuations, but the improved control logic could achieve smoothing out the fluctuation, with stability comparable to or even higher than that of the DPD sensor. The practicality and reliability of the amperometric sensor in electrochlorination-based BWMS were further verified through SB testing.

电氯化压载水管理系统中安培总残余氧化剂传感器的性能评价。

目前，安瓿总残留氧化剂（TRO）传感器的性能研究仅处于台架试验阶段，尚未在压载水管理系统（BWMS）的具体海上条件下进行。本研究通过与现有的二苯二胺（DPD） TRO传感器的比较，探讨了电流型TRO传感器在陆基生物功效（BE）测试、运维（O&M）测试以及舰载（SB）测试中的应用。结果表明，在有效BE测试周期和运行时间超过47小时的O&M测试中，安培传感器与DPD传感器的平均TRO测量偏差在±10%以内。安培传感器测得的TRO值波动较大，但改进后的控制逻辑可以实现对波动的平滑，稳定性与DPD传感器相当甚至更高。通过SB测试，进一步验证了该安培传感器在电氯化BWMS中的实用性和可靠性。
