摘要
为保障宁波市居民供水安全,在水源水库入库口建设了复合生态湿地,工程共分为两期。通过研究湿地建设背景、湿地构成、湿地运行效果等,分析生态湿地对水库水质影响的结果表明,复合生态湿地不仅能够有效脱氮除磷,抑制藻类生长,而且通过植物-微生物协同作用能够消除村落与农业面源污水带来的农药、抗生素等微量持久有机污染物。
To ensure the water supply safety for the residents in Ningbo City,a compound ecological wetland is constructed in two phases at the entrance of the water source reservoir.Considering the construction background,wetland composition and operation performance,the influences of ecological wetland on reservoir water quality are analyzed.The results show that the compound ecological wetland could not only remove nitrogen and phosphorus in the water,but also inhibit the growth of algae.In addition,trace persistent organic pollutants such as pesticides and antibiotics brought by non-point village and agricultural sewage can be eliminated by plant-microbe synergy.
