北方人工湿地污水处理技术应用研究与示范工程

针对北方地区气候特点,开展了人工湿地污水处理技术在北方的单元应用研究与工程示范。在设计上对潜流湿地越冬深度、填料结构、布集水系统和水位调整导淤方式进行优化创新,并采取了预处理与人工湿地组合工艺调节各季节运行效果;通过单元实验研究了湿地应用的工艺条件(深度、水力负荷、污染负荷),以及湿地的保温效果与全年运行效率;介绍了利用该技术建设的示范工程概况,分析了其产生的经济、社会与环境效益。

Application Study and Engineering Demonstration of Northern Constructed Wetlands Wastewater Disposal Process

Based on the characteristic of northern climate, the unit application study and engineering demonstration of northern constructed wetlands wastewater disposal process were done. In designing, the study optimizes and innovates the deepness of subsurface-flow wetlands in winter, stuffing structure, the system of distributing and collecting water and discharging silt by changing water level. The combination process of pretreatment-constructed wetlands is used to adjust the disposing effect in different seasons. Application conditions (deepness, hydraulic load, pollutant load), insulation effect and efficiency in one year are studied by units experimentation. The paper introduces demonstration engineering's general situation and analyzes economic benefits, social benefits and environmental benefits.
