Abstract

The invention discloses a bioretention pond having the functions of percolation, retention, storage, purification, usage and discharge. The bioretention pond comprises a pond body, a water storage tank and a water guiding assembly. A soil layer and a gravel layer are arranged in the pond body, the pond body is provided with a water outlet, the gravel layer is located below the soil layer, and thewater outlet is located below the gravel layer; the height of the inner top face of the water storage tank in the vertical direction is smaller than or equal to that of the upper surface of the gravellayer, the water storage tank and the pond body constitute a U-shaped communication device, the gravel layer has an anaerobic state and an aerobic state, and the anaerobic state and the aerobic statealternately appear to remove nitrogen elements in water; one end of the water guiding assembly is disposed in the soil layer, and the other end of the water guiding assembly is disposed in the waterstorage tank to guide the water in the water storage tank into the soil layer. The bioretention pond having the functions of percolation, retention, storage, purification, usage and discharge has theadvantages of being free of energy and maintenance, high in reliability and the like.

Description

Technical field [0001] The present invention relates to the technical field of biological retention facilities, in particular to a biological retention pond with the functions of infiltration, retention, storage, purification, use and drainage. Background technique [0002] The biological retention pond in the related technology realizes the function of purifying water quality through plant growth, substrate setting and microbial colony in the substrate. However, when the rainfall in the rainy season is high, the biological retention pond is easy to be submerged, and when the rainfall in the dry season is low, the vegetation cannot get sufficient rainfall. All these have a negative impact on the ecosystem in the biological retention pond, especially affecting the normality of plants Growth, thereby affecting the setting effect of the biological retention pond. Summary of the invention [0003] The present invention aims to solve at least one of the technical problems existing in ...
