Method for improving water quality of steep-slope river by drop-aeration

A water drop aeration, river technology, applied in water aeration, river regulation, chemical instruments and methods, etc., can solve the problem that primary producers such as phytoplankton and plants cannot reproduce, benthic and large animals cannot start to inhabit, and lack Problems such as deep pools and shoals in natural rivers, to achieve the effect of reducing soil loss, good falling water aeration effect, and increasing the number

Problems solved by technology

[0003] Before the present invention, the existing methods of river management all resulted in the lack of deep pools and shoals in natural rivers, making it impossible for primary producers such as various phytoplankton to reproduce, and for benthic and macrofauna that feed on them. start to perch

Embodiment Construction

[0026] specific implementation plan

[0027] The technical idea of ​​the present invention is to change the distribution of the bankline and flow velocity by constructing river channel ecological buildings, so that the downstream water body will be disturbed, and deep pools will be washed out downstream at the low side of the rocks, and shoals will be formed downstream at the high side of the rocks. In order to form a deep pool-shoal structure that is very similar to the natural river bed. The living environment of the river has been improved, and various functions of the river ecosystem have been brought into play.

[0028] The present invention will be specifically described below.

[0029] Such as figure 1 , 2 , as shown in 3:

[0030] According to the meandering situation of concrete river course, build plant platform 6, can adopt various discarded wood (as thinning timber, abandoned sleeper on railway etc.) and some other dead wooden materials are main materials; Woo...

Abstract

The invention relates to a method for improving water quality of a steep-slope river by drop-aeration. The invention comprises the following steps: driving wood piles at two sides of a river channel, backfilling a mixture of crushed stones and soil into a riverbed between a revetment and the piles, covering vegetation to form a plant platform, pouring a trapezoid concrete pier across the river channel to form a overflow weir, and stacking block stones on the overflow weir, wherein the block stones are divided into two sides; the side with higher block stones has small gaps, and the side with lower block stones has large gaps. The invention solves the defects that existing river treatment method results in the loss of deep pools and shoals in natural rivers; primary producers such as various phytoplankton and zooplankton can not reproduce; and benthic and large animals which eat them can not inhabit the river. The invention has low cost, and good permeability, can provide aquatic animals and plants with habitat space, can form a multi-flow changing zone, a multi-organism growing zone, and a multi-fish hideout, has good drop-aeration effect, and can reduce soil loss.

Description

technical field [0001] The invention belongs to the field of restoration of water ecosystems, and in particular relates to a method for improving water quality by dropping water and aerating a river with a steep slope. Background technique [0002] Traditional river management focuses on safety considerations, and pays more attention to the optimal hydraulic radius. It simply starts from increasing the flood discharge capacity, making the river channel artificial, the cross-section simplistic, and the river bed hard. Although the goal of flood control has been achieved, the river ecosystem has been degraded and biodiversity has been greatly reduced. With the enhancement of human environmental awareness, ecological concepts and living standards, the whole society has more and more urgent requirements for ecological restoration and reconstruction of degraded rivers. The idea of ​​river near-nature governance or river ecological restoration is proposed for the degradation of r...
