浅析潍坊市中心市区城市供水水源地水质情况

Analysis on the water quality of the urban water supply sources for the central area of Weifang City

针对潍坊市两处主要水源地水质情况进行了连续3年19项指标的监测分析研究,并对其中的感官性状和一般化学指标、有机综合指标、毒理指标、生物指标等关键指标进行了重点分析,根据年均值、最大值、最小值的变化情况,对潍坊市水源水质污染的发展趋势做出了合理总结和评估。结果表明,一些重要的毒理指标正呈现逐渐下滑的趋势,波动幅度也逐渐减小;但从藻类指标来看,两处水源均为高藻水源且近年来显示为不同程度的上升。该结果可应用于潍坊市中心城区饮用水水源水质的风险预控,有助于潍坊市中心城区水源水质的风险管理。

The water quality monitoring of two main water source areas was conducted to analyse and to investigate within three consecutive years by 19 indicators. The key indicators, such as sensory properties and general chemical indicators, synthetic organic index, toxicological index and biological indicators were analyzed significantly. The reasonable conclusion and evaluation were made in the development trend of water source contamination in Weifang City according to the variation of annual average values, maximum and minimum values. The results indicated that a gradually declining trend was displayed in some important toxicological indexes, the fluctuation range was also gradually reduced. From the algae indicators, the two water sources were high algae-laden water and displayed as different levels of rising in recent years. The results could be applied to the pre-control risk about the drinking water quality, which was helpful to the risk management of water source quality for the central area of Weifang City.
