Abstract

The invention discloses an ecological island type water purification filter dam for filtering and purifying urban river water, the water purification filter dam comprises a base built at the bottom of a river, left and right submerged dam sections built on the base, and a central ecological island section connected with the left and right submerged dam sections to form a whole, the submerged dam sections on the left side, the right side and the central ecological island section are formed by piling gabions filled with water purification filler, the crest elevation of the submerged dam sections on the left side, the right side and the central ecological island section is 10-20 cm higher than the normal water level, and stone stone steps for pedestrians are arranged on the tops of the submerged dam sections on the left side, the right side and the central ecological island section in the dam axis direction, and aquatic plants are planted on the ecological island section. The ecological island type water purification filter dam is easy to install, convenient to clean and capable of being repeatedly used, has a water purification function and a landscaping effect, is a technology integrating water purification, landscape improvement and ecological hydrophilicity, and has high application value.

Description

technical field [0001] The invention relates to the technical field of ecological filter dams, in particular to an ecological island type water purification filter dam used for urban river water filtration and biological purification. Background technique [0002] Ecological filter dams, also known as permeable dams or filter dams, are built with gravel, pebbles, crushed stones, etc. in the river without affecting the flood discharge of the river. The effect of river flow velocity and river surface shape. [0003] At present, in order to maintain the structural stability of the ecological filter dams used in urban river courses, the cross-section is mostly built as a uniform ladder body, and in order to improve the water quality purification effect of the ecological filter dam, the most common method is to improve the matrix of the ecological filter dam. That is, different filter materials are doped in the dam body to improve the purification capacity of the dam body. Howev...
