Ecological Water Conservation Method of Island Wetland
A wetland and island technology, applied in chemical instruments and methods, biological water/sewage treatment, sustainable biological treatment, etc., can solve problems such as inability to provide enough water for wetland ecosystems, failure to achieve water conservation goals, and decline in water storage capacity. Achieve the effect of increasing the number of consumers, reducing heating, and increasing water storage capacity

Embodiment 1
[0040] Example 1: Weizhou Island Niujiaokeng Wetland
[0041] like Figure 1-3 As shown, with reference to the island wetland ecological water conservation method provided by the present invention, the Niujiaokeng wetland on Weizhou Island is restored, and the specific steps are:
[0042] Step 1. Build a water retention dam at the downstream mouth of the naturally formed runoff ditch in the Niujiaokeng Wetland. The length of the water retention dam is 1m, the height is 1m, and the thickness is 50cm. The top of the water retention dam is provided with 2 A sunken water outlet, the water outlet is in the shape of a cuboid with a length of 30 cm, a height of 15 cm, and an interval of 15 cm;
[0043] Step 2, take the dam as the starting point to repair the 1518m long described runoff ditch upwards, clean up the silt in the runoff ditch and heighten the ditch embankment, so that the width of the runoff ditch reaches 0.8m, and the depth reaches 0.7m (water storage capacity 850m 3 )...
Embodiment 2
[0053] Example 2: Weizhou Island Kengzixi Wetland
[0054] like figure 1 , 2 , 4, with reference to the island wetland ecological water conservation method provided by the present invention, the Kengzixi Wetland of Weizhou Island is repaired, and the specific steps are:
[0055] Step 1, build a water retention dam at the downstream ditch mouth of the naturally formed runoff ditch in the Kengzixi Wetland. The length of the water retention dam is 6m, the height is 1m, and the thickness is 80cm. The top of the water retention dam is provided with 5 A sunken water outlet, described water outlet is rectangular parallelepiped, and its length is 60cm, and height is 30cm, and interval distance is 30cm, builds a shallow pool outside the dam, builds juvenile fish habitat environment, described runoff inside the dam. The downstream of the ditch builds a reservoir, the depth of the reservoir is 2m, the angle between the bottom of the reservoir and the side wall is 120 °, the bottom of t...
