中文摘要:

      污水再生利用是减少水体污染、缓解水资源供需矛盾和促进城市经济社会可持续发展的重要途径，但公众的偏见和排斥严重制约再生水处理技术的推广和发展。本文整合技术接受拓展模型和技术准备度理论，构建公众参与再生水回用意愿影响因素模型，运用结构方程模型和人工神经网络进行两阶段实证检验。研究表明：感知有用性和感知易用性对公众参与再生水回用意愿有显著正向影响；便利条件和主观规范分别对感知易用性和感知有用性起显著提升作用；技术准备度的消极因素极大地阻碍了公众再生水回用意愿的提升。基于上述结论，本文提出提升宣传的有效性，完善城市再生水配套设施及相关激励政策，联合社区、学校、企业等平台协同推进再生水处理技术推广工作等对策建议，为政府制定科学有效的干预政策，引导公众使用再生水提供重要的理论参考和实践指导。

英文摘要:

      Sewage reuse is an important way to reduce water pollution, alleviate the contradiction between water supply and demand and promote the sustainable development of urban economy and society. However, the public prejudice and rejection seriously restrict the popularization and development of recycled water disposal technologies. This paper integrates the technology acceptance expansion model and the technology readiness theory, constructs the influencing factors model of public participation willingness to reuse recycled water, and uses structural equation model and artificial neural network to conduct two-stage empirical test. The results show that perceived usefulness and perceived ease of use have significant positive impact on public willingness to participate in recycled water reuse, and facilitating conditions and subjective norms significantly improve perceived ease of use and perceived usefulness respectively, and the negative factors of technological readiness greatly hinder the improvement of public willingness to reuse recycled water. Based on the above conclusions, it is proposed to improve the effectiveness of publicity, improve urban reclaimed water supporting facilities and related incentive policies, and cooperate with communities, schools, enterprises and other platforms to promote the promotion of reclaimed water treatment technology. The research results provide important theoretical support and implementation suggestions for the government to formulate scientific and effective intervention policies and guide the public to use recycled water.
