黄金水位人工湿地技术

Technology of Constructed Wetland with Gold Water Level

黄金水位人工湿地是一种标准化的潜流型人工湿地,其主要特征就是以黄金水位栽培理论为指导,将湿地植物的灌排水位控制在根系长度从上往下的0.618位置。污水在上级沉淀、过滤、吸附后流向下级基质填料床,黄金水位人工湿地的水力负荷和污染负荷大,对BOD、COD、SS、重金属等污染指标的去除效果好,没有恶臭和孳生蚊蝇现象。

Constructed wetland with gold water level is a standardized subsurface constructed wetlands, its main feature is to take theory of cultivation at gold water level as guidance to control the level of irrigation and drainage for plants in wetland at 0.618 cm from the top to down position of root length. Sewage flows to the lower matrix packed bed after the higher precipitation, filtration and adsorption, and hydraulic load and pollution load of the artificial wetland with gold water level are large, therefore it has good removal effect for heavy metals and other pollution indicators, such as BOD, COD, SS, etc., and there is no malodor and mosquito breeding phenomenon.
