An organic composite soil high-efficiency ecological water purification
system comprises a wall body and a filter
bed in the wall body, wherein a
surface water distribution
pipe is arranged above the wall body, a water outlet is formed below the wall body, the filter
bed is sequentially divided into a
plant growth area, a primary
sand filter layer, a rapid infiltration layer, a
water storage layer, a slow infiltration layer and a water outlet layer from top to bottom. The purification process adopts the dry-wet alternative way, and comprises four cycles including a water inlet rapid infiltration period, a
water storage slow infiltration period, a slow infiltration deep purification period, and an empty
recovery period which cycle. The organic composite soil high-efficiency ecological water purification
system has the characteristics of small occupied area, high
impact-resisting load, stable water outlet, short construction period, low cost, low capital construction investment, convenient maintenance and management, low operation cost and low secondary
pollution (very small
sludge production) and good ecological landscape benefits. The water purification
system is suitable for large-area popularization in the domestic
sewage treatment in rural areas and suburb areas, and is also suitable for organic
pollution remediation and
pollution control of water bodies such as small rivers and lakes.
