摘　　要：目的:了解东营市东营区2022—2024年生活饮用水中溶解性总固体和总硬度的浓度水平,为改善东营区水质提供参考。方法:收集东营市东营区2022—2024年生活饮用水中溶解性总固体和总硬度实验室检测数据,并对数据进行统计分析。结果:156份水样的溶解性总固体和总硬度指标均达到合格标准,其中溶解性总固体平均值是605.46 mg·L^(-1),总硬度平均值是256.01 mg·L^(-1)。出厂水和末梢水在溶解性总固体和总硬度含量上未见显著差异(P>0.05)。枯水期的总硬度和溶解性总固体含量均高于丰水期(P<0.05)。口感好的水样占比66.7%,口感一般的水样占比33.3%。水样均为高硬水,占100%。结论:东营市东营区近年来的生活饮用水口感较好,但总硬度整体偏高,建议供水部门适当采取相应的水质改善措施。Objective:To understand the concentration levels of total dissolved solids and total hardness in drinking water in Dongying district from 2022 to 2024,providing a reference for improving water quality in Dongying district.Method:The laboratory detection data of dissolved total solids and total hardness in drinking water from Dongying district,Dongying city,from 2022 to 2024 were collected,and statistical analysis was conducted on the data.Result:The soluble total solids and total hardness indexes of 156 water samples reached the qualified standard,in which the average value of soluble total solids was 605.46 mg·L^(-1) and the average value of total hardness was 256.01 mg·L^(-1).No significant difference in soluble total solid and total hardness content between factory water and terminal water(P>0.05).During the dry season,both total hardness and dissolved total solids were higher than during the wet season(P<0.05).Water samples with good taste accounted for 66.7%,while those with average taste accounted for 33.3%.All water samples were high-hardness,accounting for 100%.Conclusion:In recent years,the taste of drinking water in Dongying district,Dongying city has been good,but overall total hardness is relatively high.The water supply department should take appropriate measures to improve the water quality.
