2008—2015年广州市市政水源水质状况分析
|
摘要
目的了解"西江引水工程"对广州市市政水源水水质的影响。方法收集和整理分析2008—2015年广州市市政水厂水源水监测结果。结果 2008—2015年市政水源水项次合格率呈上升趋势,不合格项目数减少,耗氧量、氨氮浓度降低,2015年项次合格率达97.1%(761/784),主要不合格项目为耐热大肠菌群和铁。NZ水厂的水源水项次合格率最高为95.4%(855/896),SX水厂的水源水项次合格率最低为88.7%(298/336)。不同水源水项次合格率高低依次为西江>北江>东江>其它;西江水源水的项次合格率最高为96.1%(2 153/2 240)。结论 "西江引水工程"极大地提高了广州市市政水源水的水质和城市供水保障能力。
Objective To analyze the influence of West River Water Diversion Project on the municipal source water quality in Guangzhou. Methods The monitoring data of source water quality from municipal water works in Guangzhou were collected and analyzed during 2008-2015. Results With less unqualified indicators and lower levels of COD and ammonia nitrogen,the qualified rate of indexes modified by monitoring frequency for municipal source water increased gradually from 2008 to 2015,and reached 97.1% in 2015,the main unqualified indexes were heat-resistant coliform bacteria and iron.The qualified rate of indexes modified by monitoring frequency for municipal source water showed the highest level(95.4%) for NZ water works,while the lowest(88.7%) for SX water works; they ranked as follows, West River(96.1%, 2 153/2 240),North River, East River and the other water sources. Conclusion The implement of West River Water Diversion Project greatly improves the municipal source water quality and the security of urban water supply in Guangzhou.
