摘要:

随着水资源短缺问题的日益突出,如何提高水资源的重复利用率是必须解决的问题。灰水是居民日常生活中排出并经源分离后的生活污水,具有产生量大、成分复杂、时空差异、回用性高的特点,对灰水进行处理后回用是缓解水资源短缺问题的有效途径。通过文献调研和案例考察,总结了目前灰水处理的技术现状,分析了各类技术的优缺点,同时调研了国内外有关灰水的应用案例及政策,并厘清了目前灰水回用存在的主要问题。针对不同水质和水量特征的灰水,应选择合适的处理技术。受当地政策、经济以及用户接受程度的影响,目前灰水回用的规模多偏向于中试研究和公共建筑,难以在灰水的产生端即居民小区内就近回用。未来可通过技术研发、出台法律法规、加强宣传和强化管理等促进对灰水的再生利用,进一步实现水资源的节约集约利用。

Abstract:

With the increasingly prominent shortage of water resources,how to improve the reuse rate of water resources is a problem that must be solved. Grey water is a kind of domestic sewage discharged from the daily life of residents and separated by source. It has the characteristics of large production, complex composition, spatial and temporal differences, and high reusability. The reuse of grey water after treatment is an effective way to alleviate the shortage of water resources. Through literature research and case study, the current technical status of grey water treatment was summarized, the advantages and disadvantages of various technologies were analyzed, the application cases and policies of grey water were investigated, and the main problems existing in the reuse of grey water were clarified. Appropriate treatment technologies should be selected according to the characteristics of different grey water quality and quantity. Affected by local policies, economy and user acceptance, the current scale of grey water reuse was mostly biased towards pilot-scale research and public buildings, and it was difficult to reuse the nearest grey water in the residential area. In the future, the recycling of grey water could be promoted through technology research and development, introduction of laws and regulations, strengthening publicity and strengthening management, so as to further realize the economical and intensive use of water resources.

Key words: source separation, grey water, reclaimed water, reuse
