摘　　要：目的 了解湛江市区自来水水质状况,为改善水质提供科学依据。 方法 按全国监测方案,对市区10间水厂的水质连续5年进行监测及对结果进行分析。 结果 5年水质项次合格率从高到低为:出厂水>管网水>地下水>地面水,地下水、出厂水的合格率差异无显著性,地面水2003年的合格率显著高于1999、2000年,管网水2003年的合格率显著高于1999、2000、2001年。水质综合评价:地面水、地下水、出厂水、管网水分别为二级、五级、一级、一级,不合格指标主要是地面水的细菌学指标、其它水样的感官和化学指标。 结论 今后应重点加强饮用水源的卫生防护和用户支管的更新、改造。Objective To understand condition of tap water quality in Zhanjiang City, and provide scientific basis for improvement of water quality. Methods Based on the National Monitoring Scheme, water qualily of 10 water suppliers were monitorred continuously for 5 years, and monitoring results were analysed. Results The qualified rate of indexes-frequency of weter quality during 5 years were in the following order:finished water > water supply pipes > ground water > surface water. No significant differences were found in ground water and finished water, the qualified rate of surface water of 2003 was significantly higher than that of 1999 and 2000, the qualified rate of water suppy pipes of 2003 was significantly higher than that of 1999,2000, and 2001 .the results of com prehensive evaluation of warer quality show that:surface water .ground water,finished water,water supply pipes were grade 2, grade 5, grade 1 and grade 1, respectively; unqualified indexes were mainly bacteriological of surface water and the sense and chemistry index in the other water sample. Conclusion Efforts should be made on the hygienic protection of drinking water source and reform and renewal of customer pipes.
