Problems solved by technology
[0004] Among the existing technologies, the current commonly used methods for the treatment of artificial landscape water bodies are integrated equipment filtration or ecological natural adsorption and precipitation. Integrated equipment filtration refers to the water quality through additional filtering equipment before external water diversion into the ecological filter bed. Filtration has the defects of high equipment cost and operation and maintenance cost, but relying only on the natural adsorption and sedimentation of the ecological filter bed has the problems of low efficiency, large interference from the external environment, and poor reliability

Abstract
The invention provides an ecological filter bed and an ecological filter system. The ecological filter bed comprises a fence, an ecological filler arranged in an area defined by the fence, and a watersupplementing pipe penetrating through the fence and buried in the ecological filler, the ecological filler comprises a substrate layer located at the bottommost layer, a vegetation planting layer located at the topmost layer and multiple stages of ecological filter layers arranged between the substrate layer and the vegetation planting layer, every two adjacent stages of ecological filter layersare filled with different ecological filter materials, and the water supplementing pipe is buried in the substrate layer. The multiple stages of ecological filter layers are arranged between the substrate layer and the vegetation planting layer of the ecological filter bed, and the water supplementing pipe is buried in the substrate layer, so that water flows reversely flow through the multistageof ecological filter layers from bottom to top in order to effectively filter external water; and the ecological filter bed and the ecological filter system have the advantages of low manufacturing cost, small external environment interference, high filtering efficiency and good treatment reliability.
Description
technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an ecological filter bed and an ecological filter system. Background technique [0002] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements for drainage or reuse. Sewage treatment usually includes industrial wastewater treatment, domestic sewage treatment, agricultural and rural sewage, urban landscape water treatment, etc. [0003] Landscape water usually refers to water bodies used for visual viewing, and is usually divided into two categories: one is natural water features, such as natural lakes, rivers, etc.; the other is artificial water features, such as ponds, artificial lakes, small urban rivers, etc. It is open surface water with very low self-purification capacity and is very vulnerable to pollution. Artificial landscape water bodies usually need to divert water from the outside to maintain the capacity of the wat...
