摘要
针对水质型缺水的嘉兴地区,进行了人工湿地处理技术改善饮用水源地水质的探索。介绍了嘉兴市石臼漾水厂人工湿地一期工程的设计和运行工艺流程。工程实施后对水质进行了监测和分析,并对工程所带来的经济、社会、环境等综合效益进行了评估。分析结果表明,主要水污染物降低了一个类别,水厂进口水质基本达到了《国家地表水环境质量标准》(GB3838-2002)规定的Ⅲ类水标准,基本上实现了预期的目标。经过近一年的试运行表明,嘉兴市石臼漾水厂人工湿地一期工程基本上达到了预期的目标。对湿地运行存在的一些问题和不足进行了分析,提出了改进的措施和建议。
In the light of pollution-induced water shortage area of Jiaxing City,the artificial wetland treatment technology was applied to improve the water quality at drinking water source area to make new exploration and experiments in water quality improvement.We briefly introduce the design and technology process of Stage I artificial wetland works of Shijiuyang Waterworks in Jiaxing City.After the works completed,we analyze the water quality and evaluate the overall benefits of economy,society and environment,etc.brought by the works.The analysis results show that the water quality classification of the main pollutants decreases by one grade.The water quality in the entrance of water works meets the national standard of grade III.After 1 year＇s operation,the expected goals of Stage I artificial wetland works are achieved.The existed problems in wetland operation are analyzed and improvement measures and suggestions are put forward.
