%X 通过对苏南某工业园区蓄水池贮存的屋面雨水进行为期一年的水质监测，分析水质变化规律，为工业园区雨水资源化利用方案提供基础数据支持。实验结果显示：蓄水池内水样各项生物化学指标浓度在秋季最高，春季、夏季次之，在冬季浓度最低。由于SS共沉降和微生物活动，随着蓄水时间延长，池内水质理化指标(总氮除外)均有所降低，总大肠菌群浓度总体呈升高趋势，但幅度不大。总大肠菌群和浊度指标一年四季均达不到《城市污水再生利用 城市杂用水水质》(GB/T 18920-2020)的要求，若调蓄池内雨水用于冲厕、道路清扫、消防、城市绿化、车辆冲洗、建筑施工，还需要过滤、消毒等措施。<br />
Through monitoring the roof rainwater stored in an industrial park in southern Jiangsu for one year, analyzing the water quality changes, and providing basic data support for the rainwater resource utilization, the results show that the concentration of various biochemical indicators of the water samples in the reservoir is the highest in autumn, the second in spring and summer, and the lowest in winter. Due to SS co-sedimentation and microbial activity, the physical and chemical indexes of the water quality (except for total nitrogen) decreased by the time, and the overall concentration of the total coliform group small increased. The total coliform group and turbidity do not meet the requirements of The Reuse of Urban Recycling Water-Water Quality Standard for Urban Miscellaneous Use (GB/T 18920-2002) all the year round. If the rainwater in the storage tank is used for flushing, road cleaning, fire fighting, urban greening, vehicle washing and construction, filtration and disinfection measures are also needed.
