Embodiment 1

[0021] As shown in the attached figure, the full-section water wetland purification system under the normal water level of the river course includes an overflow dam 1 poured with concrete or reinforced concrete, a water dike 2 poured with sandless concrete, and a wetland for purifying water 3. Flood period Flow through the main channel 4 and the trapezoidal diversion opening 5 .

[0022] First, set up cofferdams upstream and downstream of where the wetland purification system is to be built, and pump the water in the cofferdams. Then, on the basis of clearing up the sediment at the bottom of the river course, construct overflow dam 1, trapezoidal diversion opening 5 and diversion dike 2, one end of overflow dam 1 is connected with the upstream end of diversion dike 2, and the other end is connected with the upper end of the river course One side of the embankment is connected, the downstream side of the overflow dam 1 is the main river channel 4 during the flood period, and th...

Abstract

The invention discloses a full-section water wetland purification system suitable for a normal water level of a river. The system comprises four parts, namely an overflow weir, a water distribution dike, a wetland for purifying water and a main flood period overflowing river. In low water seasons and the normal water level, all the water from the upstream flows through the wetland, thus the system can play a role in purifying the water; and at a flood period, the water level exceeds the overflow weir, the water flows through all sections, a narrow trapezoidal diversion port constructed in the system plays roles of water bundling and damming during the flood, the resistance is higher if the flood is greater, and more flood is compelled to flow to the wider and tendency-along flood discharge trunk river so as to reduce the flood flow of the wetland on the premise of not obstructing the flood discharge capacity and effectively protect the wetland. Moreover, according to the specific terrain of the river, structure forms of the wetland purification system can be connected in series so that the river water can be subjected to multistage purification. The construction method can be used for effectively purifying the water.

Description

technical field [0001] The invention relates to a full-section water wetland purification system suitable for non-navigable rivers with relatively gentle water flow under normal water levels, and belongs to the field of river water environment management and ecological restoration. Background technique [0002] The basic components of a river include banks (levees), river beds, and channel water bodies. For a long time, experts and scholars have proposed many technologies and methods for in-situ pollution prevention and ecological restoration of rivers according to the different characteristics of the three. For the river bank (levee), various ecological revetment technologies and methods have been developed; for river water bodies, technologies and methods such as biologically enhanced purification and aquatic plant restoration have been proposed; for river beds, technologies and methods for ecological dredging to reduce endogenous pollution have been proposed. [0003] Ge...
