Embodiment 1

[0013] Example 1: Bank slope construction for river water pollution protection

[0014] Such as Figure 1-2 As shown, three filter absorption areas are set on the top of the slope on the water side of a certain river, and one absorption area is built at the bottom of the slope; each filter absorption area is composed of a vertical filter structure 20 and a horizontal filter absorption structure 21, and the vertical filter structure 20 is composed of filter body 13, water permeable plate 11 and filter plate 12. The horizontal filter absorption structure 21 is sequentially composed of anti-seepage layer 4, permeable layer 5, horizontal separation layer 6, plant absorption layer 7 and shore plants 9 from bottom to top, of which the first A filter layer 8 is also set between the anti-seepage layer 4 and the permeable layer 5 of the three filter absorption areas;

[0015] The bottom of the vertical filter structure 20 of each filter-absorbent zone is higher than the top 50mm of th...

Abstract

The invention relates to an ecological anti-pollution bank slope construction method for a river and a lake. The ecological anti-pollution bank slope construction method for the river and the lake is characterized in that three filtration absorption zones are arranged on a slope top on the side, facing the water, of a river or a lake, and an absorption zone is built at a slope bottom; surface water flowing from a river bank to the river or the lake passes through facilities constructed by the method, is collected by a collecting pool, and then enters the absorption zone at the slope bottom through the three filtration absorption zones on the slope top, drainage pipes and drainage ditches in sequence; the filtration absorption zones on the slope top are composed of vertical filtering structures and horizontal filtering absorbing structures, the horizontal filtering absorbing structures are composed of seepage-proofing layers, permeable layers, horizontal separating layers, plant absorbing layers, plants on the bank and filtering layers; the absorption zone at the slope bottom is composed of water plants, planting soil, a vertical separating layer and an anchor pile. The ecological anti-pollution bank slope construction method for the river and the lake is high in purification rate, high in anti-pollution capability and remarkable in environmental benefit.

Description

technical field [0001] The invention relates to a river and lake ecological anti-pollution bank slope construction method, which is a method for preventing lake and river water pollution and belongs to the field of environmental ecology. Background technique [0002] In recent years, with the rapid development of the economy, more pollutants have been discharged into the environment, and rivers and lakes have been polluted and damaged to varying degrees. The prevention and restoration of surface water pollution has become an urgent problem to be solved. According to the survey, the pollution of rivers and lakes is mainly through surface runoff, so it is very important to strengthen pollution prevention. At present, there are many ways to protect surface water pollution at home and abroad. In addition to strengthening management and reducing the impact on rivers and lakes by reducing the discharge of pollutants, the most effective method is to use ecological bank slope protec...
