摘  要:
论述了中水在居民住宅中应用的经验及所存在的问题.介绍了中水的调节氧化技术,以及将调节容量转化成氧化工作空间的效果;分析了中水的化学、物理和生物指标;总结了中水原水容量调节、利用的主要方法.风机电耗占中水处理总电耗的80%左右,提出渐减曝气和溶解氧负反馈—变频控制风机风量,使风机综合节能效果提高60%左右,有效地控制了中水处理成本,进而提高了中水处理的经济效益.对中水在居民家中应用和管理也提出了建议.

摘  要:
Experience and existing problems of reclaimed water reuse in residential buildings is discussed in this paper.Adjusting oxidation technology and its effect is introduced,which transforms the capacity adjustment into oxidation work space adjustment;Chemical,physical and biological index of wastewater are analyzed;The main methods for original wastewater capacity adjustment and utilization are summarized.Because of electrical energy consumption of fans is about 80% of the total power consumption of water treatment,we recommend a decreasing aeration and dissolved oxygen negative feedback-Frequency-conversion control of fan flow,which fan comprehensive energy-saving effect is increased to more than 60%.Therefore,total water treatment cost is effectively controlled and economic benefit is significantly improved.In addition,suggestions of application and management of waste water in resident's house is thrown out.
