Embodiment Construction

[0019] Below by embodiment and in conjunction with accompanying drawing, the present invention will be further described:

[0020] Such as figure 1 As shown, a crescent array diversion interception purification system is mainly composed of several crescent array diversion interception purification groups arranged at intervals along the water flow direction in the river channel, each crescent array diversion interception purification group is composed of stone Cage net base 1, crescent cage 2 and ecological floating island 3 are formed.

[0021] The gabion net base 1 is a rectangular net cage with a width of 3m-5m and a height of 0.4m-0.6m, and is longer than wide, and the length of the rectangular net cage is set according to the width of the river. The rectangular cage adopts a wire diameter of 2mm-4mm, and the tensile strength is not less than 38kg / m 2 Low-carbon steel wire, coated with a layer of polyvinyl chloride film, the wire diameter becomes 3mm-4.5mm, and it is made...

Abstract

The invention relates to a crescent array diversion, sewage interception and purification system comprising multiple crescent array diversion, sewage interception and purification sets sequentially arranged in a river channel at intervals in the water flow direction. Each crescent array diversion, sewage interception and purification set comprises a stone cage net base, crescent cages and an ecological floating island. The stone cage net bases are filled with stone. The corresponding crescent cages are woven above each stone cage net base and are arrayed in two lines at equal intervals along the two long sides of the stone cage net base. The crescent cages are each arranged in an inclined manner and are placed in a one-forward and one-backward crossed manner. The number of the crescent cages on each left line and the number of the crescent cages on the corresponding right line differ by one. Every two corresponding lines of crescent cages are arranged in a left-right staggered manner.Each crescent cage is filled with biological ceramsite with the grain size being 20 mm to 30 mm. Artificial aquatic weed is woven at the bottoms of the crescent cages. Each ecological floating islandis placed between the two corresponding lines of crescent cages in a centered manner. The system has a diversion, sewage interception and purification comprehensive processing effect on water qualityin the river channel, the ecological repair effect of water body environments can be remarkably improved, and construction is easy.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a river purification system. Background technique [0002] Human beings' governance of river courses has gradually developed into the stage of ecological restoration after going through the stages of engineering governance and natural transformation. River ecological restoration refers to using the principles of ecosystems to use various methods to restore the biological population and structure of the damaged water system, rebuild a healthy aquatic ecosystem, restore and strengthen the main functions of the water ecosystem, and enable the ecosystem to achieve overall A virtuous cycle of coordination, self-maintenance and self-succession. [0003] Most ecological slope protection technologies based on water environment restoration use gabion cages (also known as ecological gabion nets, gabion nets), that is, steel wires are woven into rectangular cages of different speci...
