上海国际旅游度假区景观水卫生现况及对策研究

Current situation and countermeasures of landscape water sanitation in Shanghai International Resort

  • 摘要: 背景

    随着社会对景观水体的需求增加,人群与景观水体的接触机会增多,景观水的水质卫生状况备受关注。

    目的

    了解旅游度假区的景观水卫生管理和水质现况,排查卫生隐患,提出改善建议。

    方法

    于2018年7月26日—8月8日,对上海国际旅游度假区景观环境用水的卫生管理、水处理、设备等情况进行问卷调查;采集上海国际旅游度假区9处景观水水样和2处水源水样,检测总大肠菌群、耐热大肠菌群、色度、浑浊度、pH值等36项指标;并对9处景观水水样增测嗜肺军团菌,对5处景观水水样增测空气细菌总数。

    结果

    有4处景观水体进行净化和消毒处理,3处和1处景观水体分别只采用净化处理或消毒处理,另1处景观水体采用水体软化处理。5处景观水体区域没有配备消毒剂存放专用场所。6处景观水体有日常水质检测记录。5处喷雾区域的细菌总数在2~3个,9份水样均未检出嗜肺军团菌,9份水样的游离余氯含量均未达标,3份水样的一氯胺含量不达标,3份水样的菌落总数超标,2份水样检出了总大肠菌群和耐热大肠菌群。9处水样的总合格率为83.3%~97.2%。

    结论

    该度假区部分景观水体有水质污染问题,景观水体水源的水质较好。应高度重视景观水卫生状况,完善法律制度建设,加强信息化建设,加大水质检测及监管力度,探索联合监管模式,保障游客及公众的健康。

     

    Abstract: Background

    As society's demand for landscape water bodies increases, people are more likely to be exposed to landscape water bodies; therefore, the sanitary quality of landscape water has attracted much attention.

    Objective

    This study aims to understand the landscape water sanitary management and water quality in a tourist resort, investigate potential sanitation hazards, and propose improvements.

    Methods

    From July 26th to August 8th 2018, a questionnaire survey was conducted on the sanitary management, water treatment, and equipment of landscape water in Shanghai International Resort. Nine landscape water samples and two source water samples of Shanghai International Resort were collected and detected for 36 indicators including total coliforms, heat-resistant coliforms, chromaticity, turbidity, and pH. The 9 landscape water samples were additionally tested for Legionella pneumophila, and 5 landscape water samples from landscape spray areas were additionally tested for total air bacteria.

    Results

    Four landscape water bodies were reported being purified and disinfected, 3 landscape water bodies were only purified, 1 landscape water body was only disinfected, and 1 landscape water body was subject to water softening process. Five landscape water areas did not have specific places for disinfectant storage. Six landscape water bodies had daily water quality inspection records. The total number of bacteria in the 5 spray areas was 2-3. No Legionella pneumophila was detected in the 9 water samples. Free residual chlorine content in 9 water samples, monochloramine content in 3 water samples, and the total number of colonies in 3 water samples exceeded the related national standards. Total coliforms and heat-resistant coliforms were positive in 2 water samples. The overall qualified rates of the 9 water samples were 83.3%-97.2%.

    Conclusion

    Some landscape water bodies in the selected resort area are polluted, and the source water quality of landscape water bodies is good. Attaching great importance to the landscape water sanitation status, improving the construction of legal systems, strengthening information construction, increasing water quality testing and supervision, as well as exploring joint supervision models are proposed to protect the health of tourists and the public.
