摘要

China＇s water shortage situation is grim.Deep exploration of non-traditional water resources and relief of contradiction between China＇s economic development and water resources shortage is the only way to ensure the sustainable development of China.Urban sewage treatment and reclamation is a more stable and widely used method of non-traditional water resources development and utilization.However,urban centralized reclaimed water treatment faces many problems such as high transportation cost and difficulty in laying reusing pipe network.Relatively speaking,decentralized reclaimed water treatment technology has obvious advantages and is gradually getting more attention.In this research,three types of wastewater treatment process featured with urban decentralized low-carbon ecological technology have been mainly introduced.In addition,the operating data of relevant domestic and foreign engineering cases were analyzed from the perspectives of treatment effect,energy consumption level,applicable scale and occupied area,etc.This study considers that these three new sewage processes based on the principle of ecological engineering have the advantages of compact structure,small footprint,low water consumption,stable effluent quality,beautiful appearance and large applicable scale,and are worthy of researching and importing.
