陶然亭公园使用再生水的调查与分析

Investigation and Analysis on the Use of Reclaimed Water in Taoranting Park

随着城市水资源供需矛盾日益突出,城市公园利用再生水灌溉已经成为必然的趋势。以陶然亭公园为研究对象,对再生水用于公园的景观用水、绿地灌溉情况进行了调查与分析,并对公众对于公园使用再生水的接受度进行了问卷调查,以期为再生水在城市公园的推广利用提供现实依据和基础数据。结果表明:①陶然亭公园使用再生水进行灌溉,土壤基本可以符合相关标准,绝大部分植物可正常生长;②陶然亭公园使用再生水为湖泊水体补水,湖水水质基本符合有关标准,但存在一定的全盐量超标和水中携带植物致病菌的风险;③游客对再生水的接受度较高,但公园使用再生水的科普宣传工作不足。

With the increasingly prominent contradiction between supply and demand of urban water resources,the use of recycled water for irrigation in urban parks has become an inevitable trend.Taking Taoranting Park as the research object,this paper investigates and analyzes the use of reclaimed water for landscape water and green space irrigation in the park,and conducts a questionnaire survey on the public's acceptance of the use of reclaimed water in the park,in order to provide practical basis and basic data for the promotion and utilization of reclaimed water in urban parks.Research has shown that①Taoranting Park uses reclaimed water for irrigation.The soil can basically meet relevant standards,and most plants can grow normally;②Taoranting Park uses reclaimed water to replenish the lake water.The lake water quality basically meets the relevant standards,but there is a risk that the total salt content exceeds the standard and the water carries plant pathogens.③Tourists have a high acceptance of recycled water,but the science popularization and promotion of the use of recycled water in parks are insufficient.
