摘要
根据《建筑给水排水设计标准》(GB 50015—2019)、《室外排水设计标准》(GB 50014—2021)和《民用建筑节水设计标准》(GB 50555—2020)规定,以山西省北部某高速公路管理中心站区为实体工程对其日污水产生量和回用量进行估算。结果表明:该站区生活污水日产生量为5.85~8.1 m^(3),大于冬季站区各用水行为日回用量3.4~6.0 m^(3),小于夏季站区各用水行为日回用量6.6~15.0 m^(3),因此站区生活污水要通过冲厕、绿化浇灌、道路浇洒和汽车冲洗实现完全回用,须在冬季将处理后的生活污水通过回用水存储池进行存储,然后在其他用水量较多季节(如夏季等)使用,实现站区污水零排放是可行的。同时表明,站区生活污水的回用途径中,冬季绿化浇灌占了回用量的20.6%~35%(夏季53%~70%),冲厕占50%~61.8%(夏季20%~31.8%),汽车冲洗占5%~5.8%(夏季2%~3.1%),道路浇洒占10%~11.8%(夏季8%~12.1%),所以在回用途径中可通过调整绿化浇灌使用水量提升污水的回用率。
According to Standard for Design of Building Water Supply and Drainage(GB 50015—2019),Standard for Design of Outdoor Wastewater Engineering(GB 50014—2021),and Standard for Water Saving Design in Civil Building(GB 50555—2020),and based on the actual engineering of an expressway management center station area in Shanxi Province,the daily output and daily recycling dosage of the sewage ar e estimated.The results show that the daily output of the domestic sewage in this station area is 5.85-8.1 m^(3),larger than the daily recycling dosage of each water consumption in winter(3.4-6.0 m^(3))and smaller than that in summer(6.6-15.0 m^(3)).Therefore,to completely recycle the domestic sewage in the station area,the treated domestic sewage should be stored in the recycling water storage pool and used in other seasons with more water consumption(such as summer).It is feasible to realize zero sewage discharge in the station area.Meanwhile,among the recycling ways of domestic sewage in the station area,green watering in winter accounts for 20.6%-35%(53%-70%in summer),toilet flushing accounts for 50%-61.8%(20%-31.8%in summer),car washing accounts for 5%-5.8%(2%-3.1%in summer),and road pouring accounts for 10%-11.8%(8%-12.1%in summer),so the recycling rate of sewage can be improved by adjusting the amount of water used for green watering.
