镇江市水污染控制与海绵城市建设现状

The Present Status of Wastewater Control and Sponge City Construction in Zhenjiang City

海绵城市的建设不仅可以从根本上缓解城市缺水危机,而且对于城市的可持续性发展有着十分重要的作用。通过查阅国内外大量文献,基于镇江市统计年鉴2005~2016年的数据,对镇江市水污染控制及海绵城市建设现状进行统计分析,并从多角度探讨两者之间的相互关系。结果表明:镇江市各地区间经济发展迅速且城市化水平差异较大,城市污水控制水平逐年提高。镇江市附近城区工业废水排放量及生活污水、工业污水处理主要集中在市区,城市污水主要处理指标的去除量逐年增加。这些彰显着镇江市近几年旧城区改造试点工程、古运河中段整治、园林绿地改造等生态工程项目取得了巨大成果。海绵城市的建设不仅大幅提升城市防洪排涝减灾能力,还提高水污染控制水平、改善城市水体质量,有利于镇江市经济与环境之间可持续发展。

The construction of the sponge city could not only alleviate the urban water shortage crisis fun-damentally, but also play an important role in the sustainable development of the city. On the basic data of the statistical yearbook of Zhenjiang city from 2005 to 2016, the current status of sponge city construction and water pollution control was analyzed in Zhenjiang city through consulting a large number of literatures at home and abroad, and further explored the relationship between them from a multi-angle. The result showed that regional economic development of Zhenjiang City was rapid, and the level of urbanization was quite different, while the level of urban water pollution control increased year by year. The regional distribution of industrial wastewater discharge and domestic sewage as well as industrial wastewater treatment in Zhenjiang was mainly focused on urban district, while the main indexes of municipal wastewater treatment increased on main Years. These highlight the great achievements of the Zhenjiang city in the past few years, such as the transformation of the old city pilot project, middle canal renovation, landscaping transformation and other ecological projects. The construction of sponge city not only significantly enhanced the ability of urban flood control and drainage as well as disaster reduction, but also raised the level of water pollution control and improved the quality of urban water, which is conducive to the sustainable development of economy and environment in Zhenjiang.
