Micro-ecology filter bed

Abstract

The invention discloses a micro-ecology filter bed. The micro-ecology filter bed comprises a water inlet, wherein an overflow groove is formed below the water inlet, an upper end of the overflow groove is connected with a head end of an overflow board, a tail end of the overflow board is connected with a water inlet portion of an aerobic tank, a plurality of MBBR fixing supports and a sludge hopper are arranged in the aerobic tank, MBBR filler is arranged on the MBBR fixing supports, the sludge hopper is located at a tail end of a water flow direction, a water outlet portion of the aerobic tank is connected with a water inlet portion of a water delivery pipe, a valve is arranged on the water delivery pipe, a water outlet portion of the water delivery pipe is located above a filter bed body, a planting matrix layer, an upper layer geotextile layer, an aggregate layer, a low layer geotextile layer and a gravel layer are laid in the filter bed body from top to bottom in sequence, plants are planted on the planting matrix layer, and a water outlet is formed in the bottom of the filter bed body. The micro-ecology filter bed is suitable for a water body with a low pollution degree or low-load sewage treatment, and has the advantages of being high in degradation efficiency, low in energy consumption, low in building cost and convenient to maintain.

Description

technical field [0001] The invention relates to a micro-ecological filter bed, which belongs to the technical field of water environment treatment. Background technique [0002] Sewage and waste water produced by human production activities are directly or indirectly discharged into rivers and other natural water bodies, resulting in water pollution. At the same time, lakes, ponds and other water bodies lack fluidity, and their self-purification ability is limited, facing the problem of water quality deterioration. Commonly used water environment restoration methods include environmental water diversion, salvage of silt, chemical treatment, etc. However, these methods have problems such as large amount of engineering, high cost, and easy to cause secondary pollution. Currently, biological treatment methods, such as the micro-ecological filter bed method, are environmentally friendly and conform to the concept of ecological civilization, so they are widely used. However, th...
