摘要
人工湿地已被广泛用于处理各种类型的废水.本项研究采用复合垂直流人工湿地循环净化杭州植物园内低浓度养鱼废水,并对其处理效果进行化学分析.湿地出水的硝态氮、总磷、化学需氧量等绝大多数指标达到了国家地面水一类标准;湿地运行以后,在不进行换水的条件下,养鱼池内水质能保持较好的状态,节约了地下水和电能,产生了显著的经济效益和生态效益.
Constructed wetland has been widely applied in treating a variety of wastewater. The fishery wastewater in Hangzhou Botany Garden was purified in circulation by the compound vertical-flow constructed wetland, and its treatment efficiency was analyzed.Most indexes of outflow water, such as nitrate-N, total phosphorus and chemical oxygen demand, met the standard of first grade surface water. After constructed, the wetland could make water quality in the fish chamber better without applying underground water. This project could bring significant economic and ecological benefits.
