Convenient for maintenance and can be used as a bridge.
In this example, the ecological dam further comprises three fillers for water purification treatment, one for phosphorus removal, one for nitrogen removal, and one for oxygen increase, and one filler is provided in each dam box 10.
Specifically, each filler is in a barrel-shaped form, and can be replaced and maintained through the openable box cover 101 at the top of the dam box 10 at any time according to needs.
In this example, the phosphorus, nitrogen and oxygen removing filler forms a water treatment group and is correspondingly arranged in three side-by-side dam boxes 10. Can effectively carry out bioremediation to improve the water quality.
Specifically, the two water treatment groups are communicated with each other from the dam box 10 where the oxygen increasing filler is located. Therefore, water at the upstream can flow into the dam box from the gate cavities of the two gate valves at the same time and is discharged to the downstream from the water outlet.
Referring to fig. 2, a water outlet 10a is formed on the downstream side of the dam box 10 where the oxygen increasing filler is located, wherein the water outlet 10a extends along the length direction of the dam box 10, therefore, in this example, the dam body 1 has two water outlets 10a, so that once the gate valves 2 at the two ends are opened, the upstream water can flow into the corresponding water treatment group from the gate valves 2, and then is discharged from the water outlets 10a after being treated by phosphorus removal, nitrogen removal and oxygen increase, and the discharged water is left as an artificial waterfall, which is very beautiful.

Then, according to the information obtained by the water quality monitoring system, the working states of the water pump, the submersible sewage pump and the aerator are intelligently controlled, required agents are intelligently added in time for aeration and the like, and the indexes of the water such as pH, COD, BOD, DO, turbidity, ammonia nitrogen and the like can be monitored in real time.
Referring to fig. 4, the gate chamber q of each gate valve 2 is communicated with the cavity of the adjacent dam box 10, and each gate valve 2 includes a valve body 20 and a gate 21, wherein when the gate 21 is opened, water located at the upstream flows into the gate chamber q or is discharged from the gate chamber q to the downstream.
In this example, each gate valve 2 has two gates 21, and the two gates 21 correspond to the upstream and downstream sides of the dam 1, wherein each gate 21 can move up and down. Thus, water at the upstream of the dam body 1 enters the gate cavity q from one gate valve 2, sequentially flows through the cavities of the six dam boxes 10, and then is discharged from the gate cavity of the other gate valve 2 to the downstream; or the water positioned at the upstream of the dam body 1 flows into the dam box 10 from the gate cavities q of the two gate valves 2 and is discharged to the downstream from the water outlet 10 a. On one hand, flood discharge can be realized; on the other hand, different water outlet modes can be selected, such as: the end part of the water outlet pipe is used for discharging water or water which flows out from the outlet in a waterfall manner.
Specifically, the top of each gate 21 is correspondingly connected with a lifting handle s, and the gate 21 can realize up-and-down lifting movement by rotating the lifting handle s.
In addition, an interception grating or an interception filter screen is arranged in front of or/and behind the side gate 21 on the upstream of the dam body 1. The floating objects are intercepted, and the sundries are prevented from entering the dam box.

4. The method for biological and ecological remediation of bodies of water in different river waters according to claim 3, wherein the method comprises the steps of: the water outlet is correspondingly arranged at the upper part of the dam box where the oxygen increasing is positioned and is arranged corresponding to the downstream.
5. The method for biological and ecological remediation of bodies of water in different river waters according to claim 4, wherein the method comprises the steps of: and a drainage channel is also arranged on the upper side of each dam box and the side faces to the upstream and the downstream, wherein the water outlet is positioned below the drainage channel on the same side.
6. The method for biological and ecological remediation of bodies of water in different river waters according to claim 5, wherein the method comprises the steps of: the water outlet is communicated with the drainage channel at the same side.
7. The method for biological and ecological remediation of bodies of water in different river waters according to any one of claims 1 to 6, wherein: and a water pump and a submersible sewage pump are arranged in each dam box, and the water pump pumps the water in the previous dam box to the next dam box.
8. The method for biological and ecological remediation of bodies of water in different river waters according to claim 7, wherein the method comprises the steps of: and an aerator is also arranged in the dam box where the oxygen increasing is positioned, wherein the water pump, the submersible sewage pump and the aerator are communicated with the processor.
9. The method for biological and ecological remediation of bodies of water in different river waters according to claim 1, wherein the method comprises the steps of: the top of each dam box is arranged in a closed mode through a box cover.
10. The method for biological and ecological remediation of bodies of water in different river waters according to claim 1, wherein the method comprises the steps of: and intercepting grids or intercepting filter screens are arranged in front of or/and behind the water inlet valves of the first gate valve and the second gate valve.
