摘要: 为了分析东营市河流中氯离子浓度分布情况,掌握氯离子对东营市环境质量监测的影响情况,对东营市38个河流断面在2018年12个月份的氯离子浓度进行全面监测。发现氯离子月均值浓度低于1000 mg/L的断面有6个,在1000~2000 mg/L内的断面有20个,氯离子浓度在2000~3000 mg/L内的断面有6个,浓度高于3000 mg/L的断面有6个。结果表明,东营市河流中氯离子浓度含量高,不同采样时间、上下游不同断面的氯离子浓度变化很大。环境质量监测过程中,氯离子会对部分监测项目造成正干扰,或者导致监测方法不适用,尤其是化学需氧量、氨氮、高锰酸盐指数等项目,必须充分考虑氯离子对环境质量分析的影响,进而采取相应的措施来消除。

Abstract: To comprehensively monitor and analyze the distribution of chloride concentrations in river water as well as to understand its effect on environmental quality monitoring in Dongying, the chloride concentrations in 38 river sections of Dongying were continuously monitored in 2018. The results showed that the monthly chloride concentrations in six sections were less than 1000 mg/L, twenty sections’ concentrations were in the range of 1000~2000 mg/L, six sections’ concentrations in the range of 2000~3000 mg/L and the remaining six sections’ concentrations above 3000 mg/L. This indicates that the river water of Dongying has high chlorion content; the concentration of chlorion also greatly varied with the location of the sections (upstream or downstream) and the time of sampling. Chloride can cause positive interference to certain monitoring items or lead to the inapplicability of certain monitoring methods, especially for COD, ammonia nitrogen, permanganate index and other items. Therefore, the influence of chlorion on environmental quality analysis must be carefully considered, and a series of measures must be taken to eliminate the influence of chloride during water quality monitoring for the rivers of Dongying.

Key words: river water, chloride concentration, environmental quality, Dongying City
