Embodiment 1

[0041] Such as Figure 1-6 As shown, the present invention provides a kind of ecological management system applicable to high sediment content river courses, comprising a film-hanging unit 1 and an ecosystem unit 2, and the described ecosystem unit 2 is arranged downstream of the described film-hanging unit 1 ;

[0042] The film-hanging unit 1 is composed of at least two artificial water plant groups 3 arranged in parallel, the artificial water plant groups 3 and the revetment are vertically arranged, and the two adjacent artificial water plant groups 3 are respectively connected to the revetment on different sides thereof, A water channel 10 is arranged between the artificial water plant group 3 and the revetment, and the water channel 10 extends in a zigzag;

[0043] The artificial water plant group 3 includes a frame structure composed of two or more steel pipe piles 4, the bottom of the steel pipe piles 4 is fixed in the river bottom mud surface, and the two or more steel...

Embodiment 2

[0051] The present invention will be further described below in conjunction with the project case "a river water ecological management project in Jiangxi":

[0052] Current status of the project river:

[0053] The upstream flows through many villages, and the water and soil loss on both sides of the bank is serious. The upstream water body is turbid with high sediment content.

[0054] Project implementation:

[0055] Such as Figure 1-Figure 6 As shown, the "D"-shaped hanging membrane unit 1 is installed at the water inlet of the project river section (width 57 m), with a total length of 230 m (such asfigure 1 ), and then set the water ecosystem unit 2 to achieve the purpose of river course governance.

[0056] The "D" shaped film-hanging unit 1 is mainly composed of staggered artificial water plant groups 3, each row of artificial water plant groups 3 is 50m long and 10m wide, and a 10m blank area is left between every two rows of artificial water plant groups 3 to form a...

Abstract

The invention provides an ecological treatment system applicable to a river channel with high silt content. The ecological treatment system comprises a membrane formation unit and an ecosystem unit, wherein the membrane formation unit is composed of at least two artificial aquatic plant groups which are arranged in parallel; the artificial aquatic plant groups are perpendicular to revetments; opposite sides of two adjacent artificial aquatic plant groups are respectively connected with a revetment; a water flow channel is arranged between the artificial aquatic plant groups and the revetmentsand extends in a Z shape; and the ecosystem unit is divided into three areas by two rows of parallelly-arranged flow-guide isolation nets along the extension direction of the river channel. Accordingto the invention, the membrane formation unit can retard the flow rate of the river channel to a certain extent, facilitates settlement of large suspended substances like silts and particular mattersin water, and preliminarily settles the particular matters in the water from upstream. The ecological treatment system provided by the invention gives full play to the water-purifying function of an ecological system to build a water ecological management system for the river channel, and achieves the purposes of receiving pollution, generating purification, reducing silt content and improving transparency.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to river treatment technology, in particular to an ecological treatment system suitable for rivers with high sediment content. Background technique [0002] Affected by factors such as the environment and human over-exploitation, the sediment content of rivers in China is generally high. The main causes of high sediment concentration in rivers are as follows: [0003] 1) Vegetation coverage - one of the main determinants; [0004] 2) Soil quality - one of the main determinants; low vegetation coverage, loose soil, and river water scouring the river bank will easily increase the sediment content of the river; [0005] 3) Rainfall intensity; when the rainfall intensity is high, surface runoff scours and brings in sediment; [0006] 4) Terrain; if the terrain has a large drop and the scour kinetic energy of the surface runoff is strong, the sediment concentration will be high, and if ...
