摘要
人工湿地是指利用基质、水生植物与微生物模拟自然湿地,并通过物理、化学及生物等方法净化生活污水的一类设施,但系统的堵塞一直是影响其功效发挥和稳定运行的关键问题。综述了人工湿地发生堵塞的可能原因、系统堵塞恢复及防止系统堵塞发生的措施,提出了研究展望。
Artificial wetland is a kind of facility using matrix, water plants and microorganism to simulate natural wetland in order to purify domestic sewage via physical method, chemical method and biological method. But the system blockage is always a key problem impacts functions and stable operation of wetland. Therefore, the possible reasons-for system blockage in artificial wetland, and their corresponding renew and prevention measures were reviewed. In the end, the study prospects were put forward.
