Ecological permeable dike suitable for strengthened purification of water quality of small watershed riverway in mountainous area

Abstract

The invention relates to the field of water environment treatment and discloses an ecological permeable dike suitable for strengthened purification of the water quality of a small watershed riverway in a mountainous area. The ecological permeable dike is located in the navigation-free small watershed riverway in the mountainous area, the section, parallel to the water flow direction, of the ecological permeable dike is trapezoidal, the ecological permeable dike comprises a low-permeability ecological interception purification layer (1) and a high-permeability ecological interception purification layer (2), the low-permeability ecological interception purification layer (1) is located on a bottom layer of the ecological permeable dike, and the top elevation of the low-permeability ecological interception purification layer (1) is 10-30 cm higher than the water level of the position where the low-permeability ecological interception purification layer (1) is located during the dry season; and the high-permeability ecological interception purification layer (2) is located on an upper layer of the ecological permeable dike. An aquatic ecosystem can be rapidly formed on the surface layer of a whole dike body and plays a pole stably for a long term. The ecological permeable dike is reasonable in design, unblocked in drainage and low in construction cost.

Description

technical field [0001] The invention relates to the field of water environment treatment, in particular to an ecological permeable dam suitable for enhanced purification of water quality in small watersheds in mountainous areas. Background technique [0002] At present, many areas in my country are facing problems such as serious river pollution, poor water quality, water ecological degradation, and poor self-purification ability of water bodies. The functions of water supply and ecological landscape of rivers have been seriously affected, and there is an urgent need to strengthen governance. A large number of researches and engineering practices at home and abroad have shown that in addition to reducing pollution discharges from industrial and agricultural production and residents’ lives at the source, effective measures must be taken on the river to improve or strengthen the water environment of the river. Self-purification function. Different from rivers in Pingyuan area...
