Problems solved by technology

However, this type of ecological slope protection method is not suitable for steeper and eroded slopes, and for cities where every inch of land is expensive, it is impossible to have such a wide embankment on the river bank for ideal ecological slope protection. Therefore, For cities, the construction of a relatively ideal ecological revetment is greatly restricted, and its operability is poor, so it is basically difficult to realize
For urban rivers, especially the rivers of the ancient Jiangnan city, the river is narrow, the water is deep, controlled by man-made gates, and the situation of erect hard revetment is to resist soil erosion and loss caused by the impact of river water on the soil slope when the flow rate is high. Seriously, a semi-series of ecological slope protection technology methods appeared, that is, concrete s

Embodiment Construction

[0027] As shown in Figure 1 and Figure 2, the new revetment ecological concrete component 1 is made of ecological concrete. In order to improve the strength of the ecological concrete, steel bars or carbon fibers are added when the ecological concrete is poured; the inner cavity 2 is filled with functional filler 3, using pebbles , biological ceramsite, zeolite, immobilized microbial balls and other parts or all, according to non-point source pollution and water quality characteristics of rivers and lakes, adopt different compositions and ratios.

[0028] When controlling runoff pollution, the runoff pollution enters the inner cavity 2 through the rear side wall 6 or the upper side wall 5 of the new revetment ecological concrete component 1, and contacts with the functional filler 3 in the inner cavity 2, and uses the action of biofilm to remove organic matter and Pollutants such as nitrogen and phosphorus enter river and lake water bodies from the front side wall 4 of the ecol...

Abstract

The present invention relates to a method for eliminating urban surface source pollution and purifying river and lake water quality by utilizing slop protection built up by using shore-protecting functional members. Said new-type shore-protecting ecological concrete functional member has an internal cavity, in the internal cavity a kind of functional filling material is placed, to the filling material the biological membrane can be attached, the filling material can be pebble, biological ceramsite, zeolite and immobilized microbial spheres, etc. and their combination so as to form a biological contact oxidation system. Said invention also provides the action principle of said method, and provides the concrete steps for implementing said method.

Description

technical field [0001] The invention relates to a method for purifying urban non-point source pollution and urban river and lake water, in particular to a method for purifying urban non-point source pollution and river and lake water by using slope protection built with ecological concrete functional components. Background technique [0002] At present, there are many methods of using slope protection to control urban non-point source pollution, such as the traditional vertical stone revetment in the city. This vertical hard revetment method has played a very important role in urban flood control and saving urban land occupation. , and also has a certain effect on water and soil conservation, but this method cuts off the connection between revetment and aquatic ecosystem, and the upright hard materials seriously affect the habitat of aquatic organisms. [0003] Before the present invention, there were also many methods for ecological slope protection of rivers and lakes, suc...
