低动力复合净水系统净化生态农庄景观池水质

Purification of landscape pool water in ecology village by low-power compound water purification system

采用生物填料、阿科蔓生态基和生态浮盆等材料构建低动力复合净水系统(LCWPS)进行生态农庄人工景观池水质净化技术示范研究。系统稳定运行后的周年监测结果表明,整体系统使人工景观池的CODMn、TN、NH4+-N、TP和浊度分别下降61.1%～62.8%、36.0%～39.9%、14.3%～35.7%、66.7%～79.5%和76.8%～79.8%,水质溶解氧浓度(DO)上升72.7%～126.0%,景观池水质达到《地表水环境质量标准》(GB3838-2002)中景观水域需要的V类水质标准,并能长期保持稳定。从管理维护成本角度考虑,利用LCWPS净化生态农庄人工景观池水质能达到节能节水的目的。

Demonstration research on purifying landscape pool water in ecology village was conducted by using biological packing material, AquaMats ecobase and ecological floating bed to construct the low-power compound water purification system （LCWPS）. After the system became stable, the annual monitoring results indicated that CODMn, TN, NH4＋-N, TP and turbidity decreased by 61.1%~62.8%, 36.0%~39.9%, 14.3%~35.7%, 66.7%~79.5% and 76.8%~79.8%, respectively in the landscape pool water, while the dissolved oxygen （DO） in water increased by 72.7%~126.0%. The water quality in the landscape pool reached the V Class water of landscape water standard regulated by the Surface Water Quality Standard （GB 3838-2002） and kept stable for the long term. From the angle of management and maintainance cost, using LCWPS can achieve the aim of saving energy and water by the system in landscape pool water purification in ecology village.
