Abstract
In order to further understand the utilization of unconventional water resources in Shanghai City,various enterprises and institutions(with a monthly water consumption of over 5 000 m3),water-saving demonstration communities,and excellent cases of industrial water reuse and rainwater comprehensive utilization were selected as the survey subjects.It was found that the overall development of unconventional water resource utilization in Shanghai was relatively fast after 2010,with more micro rainwater collection facilities than sponge facilities,but the way of rainwater reuse was relatively single.Most of them were used for greening irrigation and road flushing,while a few were utilized in combination with the actual situation of the unit.The amount of recycled water was much greater than that of rainwater,but it was limited by the pipeline network and was only used for supplementing the surrounding landscape environment and supplying water to surrounding enterprises.It is suggested that the user should carry out unconventional water resource utilization according to local conditions,which can effectively solve certain water use problems.The user also should expand unconventional water resource utilization channels,and construct supporting sponge facilities and rainwater collection facilities.In the management side,pilot projects should be carried out first and gradually promoted,while strengthening policy guidance,forming incentive mechanisms,increasing publicity efforts,and further promoting the utilization of unconventional water resources.关键词
