中文摘要:
      以苏州河水质自动监测岸边站为例,根据近3年实际运行情况,从实样验收比对、连续运行比对等方面系统比较自动监测和实验室分析数据,深入探讨小型岸边站技术的稳定性和可靠性。结果表明:岸边站在线监测数据总体较为稳定,水温、溶解氧、pH、氨氮等监测结果和变化规律与实验室数据具有较好的相关性和一致性,其中,水温、pH、氨氮等指标均不存在明显差异,苏州河水质自动在线岸边站测定的数据真实可靠。加强自动站运维管理等可以进一步提高自动站数据质量。
英文摘要:
      Based on three years monitoring data of automatic water quality station of Suzhou Creek,the stability and reliability of water quality shore station were analyzed by data comparison to the laboratory. It is shown that the temperature,pH,DO,and NH3-N from the automatic water quality station and laboratory were highly correlated,and there was no difference at the significant level of 0.01. The automatic water quality monitoring system of Suzhou Creek was stable and reliable. The accuracy and stability could be improved by proper maintenance and standardized management.
