Winter cities have severe shortages of water resources. The effective classification and recycling of urban water resources that are available here are therefore significant for the sustainable utilization of water in winter cities, and snow is a potential water resource. In this research, the water quality of the snow and the pollutant composition in the vehicle roads of a typical residential community of Harbin are analyzed. It is concluded that there is a large amount of suspended substances, including chemical oxygen demand (COD), salt, ammonia, and oil in this snow. There are 27 main pollutants. The oily substances are dominated by hexadecane and are accompanied by toxic substances, including benzene, toluene, ethylbenzene, xylene (BTEX), and naphthalene. As snow is a carrier of pollutants, the underground space of the urban shallow green belt is proposed to be used to establish a snow-melting system that would integrate biological treatment devices. This method allows the year-round collection, storage, and utilization of rainwater for use in city planning and municipal technology, realizing multiple objectives and having a significant influence on further urban development.
冬季城市水资源严重短缺。因此，有效分类和回收这里现有的城市水资源，对于冬季城市的水资源可持续利用具有重要意义，而雪就是一种潜在的水资源。本研究分析了哈尔滨某典型住宅小区道路车辆雪和污染物成分的水质。结果表明，雪中含有大量的悬浮物质，包括化学需氧量（COD）、盐、氨和油。雪中存在 27 种主要污染物，油性物质主要为十六烷，且伴有有毒物质，包括苯、甲苯、乙苯、二甲苯（BTEX）和萘。由于雪是污染物的载体，因此建议利用城市浅层绿化带的地下空间，建立一个集生物处理装置的融雪系统。这种方法可以实现全年收集、储存和利用雨水，用于城市规划和市政技术，实现多项目标，对进一步的城市发展产生重大影响。
