摘要
考察了分别使用生物接触氧化和人工湿地作为核心工艺的两个建筑小区的中水处理站,系统运行稳定,出水水质满足GB/T 92018—2002《城市污水再生利用》标准,但两个中水处理站均存在设计规模偏大,处理出水得不到有效利用的问题。生活用水定额取值过大、入住率偏低、回用用途单一是造成上述问题的主要原因,针对上述2个中水处理站,提出增加中水原水量和回用用途的改造建议,同时,针对新建建筑小区中水回用工程,提出合理确定设计规模和正确计算中水原水量的建议和方法。
Biological contact oxidation and artificial wetland applied in water treatment in a residence community are stable in system operation,and the effluent quality meets the ＂Urban Wastewater Reclamation and Reuse＂standard（ GB / T 92018—2002）. There are still some problems about design scale of two water treatment station larger and the effective use of the efflent. The main causes of the problems are domestic water quota value too large,low occupancy rate,single reuse method.In view of the two water treatment stations,the suggestions on increasing reclaimed water quantity and uses were proposed. At the same time,in view of the water reuse project of newly built residence communities,the paper put forward reasonable suggestions and methods for designing suitable scale and the correct calculation of reclaim water quantity.
