Embodiment 1

[0021] 1. On-site investigation of stone-based riverbed (such as stone type and composition, slope, distribution, etc.), hydrology, pollution, flora and fauna, wind direction, etc., pay special attention to factors such as water flow size and dynamic changes, rock type, etc., and choose a river with a certain flow drop Determine the location of the ecological waterfall and the construction plan, including expected goals, construction period, engineering materials, engineering organization, engineering acceptance, maintenance plan, etc.

[0022] 2. Construction of ecological waterfall pool. Determine the area, shape, outer wall material, and internal structure of the ecological waterfall pool; planting substrate transformation, filling materials, etc. Considering that the river bed is convenient for construction during the dry season, the ecological waterfall pool is constructed in winter and spring, and aquatic plants are planted in the ecological waterfall pool. The area of ...

Abstract

The invention belongs to the technical field of resource environment engineering, and particularly discloses a method suitable for purifying a polluted water body in a stone foundation riverbed of a plateau region. The method comprises two parts of constructing an ecological plunge pool and planting aquatic plants. A pit is constructed at the selected riverbed, stone built dam type pool walls are constructed at the periphery of the pit, and the upstream pool wall is provided with a series of waterfall forming pipes and a fountain forming pipe. The topmost of the upstream pool wall of the ecological plunge pool is a pointed flood diversion or stone diversion dam, and the center of the dam is a hollow waterfall control cavity. After the current enters the waterfall forming pipes, the current is injected into the ecological plunge pool by water outlet holes at different positions in a form of waterfall. The current flowing into the fountain forming pipe enters the pool bottom along the pipe to form fountain. The bottom of the ecological plunge pool has a layer of planting matrix for planting the aquatic plants. Some aquatic animals also can be put into the ecological plunge pool to perch and reproduce. The whole ecological plunge pool forms a balanced and stable ecological system with beautiful landscape so as to purify the water body.

Description

technical field [0001] The invention belongs to the technical field of resources and environment engineering, and in particular relates to a method for purifying polluted water bodies of stone-based riverbeds in plateau areas. Background technique [0002] Many polluted rivers in the low-latitude sub-plateau region of the central Yunnan-Guizhou Plateau are dominated by stone-based riverbeds, with fragile ecosystems and poor self-repair and self-purification capabilities. The stone-based riverbed in this area is mostly composed of large rocks and pebbles, which are prone to water and soil erosion when it encounters rainfall, leaving mostly bare stones. The upper part of the riverbed is nutrient-poor stones, and the underwater part is mostly stones and polluted river water. This kind of stone-based riverbed habitat is not conducive to the fixation, growth and reproduction of most plants. In order to better control the water pollution of rivers in this area and strengthen the ...
