[0002] In the field of water ecological environment protection, we must achieve "the improvement of water environment quality constraints such as Class V sections, black and odorous water bodies, and urban and rural non-point source pollution, and the improvement of infrastructure and management mechanisms, so as to fundamentally achieve long-term cleanliness". Although my country's water environment quality has improved significantly, the imbalance and disharmony are prominent. The long-term cleanliness of urban black and odorous water bodies needs to be continuously promoted, and the treatment of agricultural and rural sewage needs to be strengthened. Deep-seated problems such as new pollutants and non-point source pollution have gradually emerged, and water pollution control has entered the deep water zone.

[0038] The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0039] The pulse ecological ditch of the utility model comprises a plurality of ditch modules connected end to end and a circulation unit 400 arranged at the end of the ditch. Each ditch module comprises a sedimentation unit 100, a purification unit 200 and an activity unit 300 arranged in sequence in the ditch from upstream to downstream.

[0040] The sedimentation unit 100 includes a sedimentation tank 120 and a garbage catching net 110 disposed in the sedimentation tank 120; the sedimentation tank 120 has a depth of 1 meter, a width that is the same as or slightly smaller than the width of the ditch module, and a length that is adjusted according to actual conditions.

[0041] The garbage fishing net includes a guide rod 111, a fixed pull rope 112, a flip pull rope 113, a net body 114 with an upper opening, and a weighted sinker 115; the guide rod 111 is set on the edge of a sedimentation tank 120. The net body 114 is fixed to the guide rod 111 by the fixed pull rope 112, and the weighted sinker 115 is fixed at the bottom of the net body to make the net body 114 sag under the action of gravity. The flip pull rope 113 is connected to the inner bottom surface of the net body 114, and the flip pull rope 113 is pulled to make the net body 114 fold from the inside to the outside.

[0042] When water flows through the garbage fishing net, it can pass smoothly. The heavier substances in the water are intercepted and precipitated by the garbage fishing net. When the sedimentation tank is filled, the garbage fishing net is retracted, the garbage is pulled to the shore, and the garbage is dumped into the garbage truck by dragging the flip rope to facilitate garbage cleaning. The garbage fishing net uses an ultra-dense fishing net with a mesh size of no less than 100, ensuring that when the net is closed to pick up the garbage, water can drain from the mesh but the garbage will not leak through the mesh, reducing the water content of the picked up garbage and reducing the volume of the garbage.

[0043] Carbon fiber ecological water grass grows in the purification unit 200 to increase the oxygen content in the water. The water treated by the sedimentation unit is purified in the purification unit. The carbon fiber ecological grass has a large surface area, which can absorb, adsorb and intercept dissolved and suspended pollutants in the water, and provide good conditions for the growth and reproduction of various microorganisms and algae; finally, a "biofilm" with strong purification activity is generated on the carbon fiber ecological grass, and the water passing through is efficiently treated through aerobic, facultative anaerobic and anaerobic action.

[0044] The movable unit 300 includes a first weir plate 310, a second weir plate 320, a permanent magnet 330 and a hydraulic buffer automatic rebounder 340; the first weir plate 310, the second weir plate 320 and the ditch together form a magnetic dam for storing water when the water volume is small and draining water when the water volume is large.

[0045] Permanent magnets 330 are arranged on the opposite sides and bottoms of the first weir plate 310 and the second weir plate 320, and permanent magnets 330 are also arranged on the bottom of the ditch at corresponding positions of the bottoms of the first weir plate 310 and the second weir plate 320; the first weir plate 310, the second weir plate 320 and the side wall of the ditch are connected by a hydraulic buffer automatic rebounder 340. The hydraulic buffer automatic rebounder 340 is an automatic door closer.

[0046] When the water flow is small, the water body is kept flowing in a pulsed manner to achieve the sedimentation of particles in the water, effectively intercept some solid waste in the river water, increase the residence time of the water body in the purification unit, achieve natural oxygenation of the water, and enhance the self-purification capacity of the river;

[0047] When the water flow is large, the water flow breaks through the magnetic connection between the first weir plate 310 and the second weir plate 320, and does not affect the irrigation, drainage and flood discharge functions of the ditch. When the water flow returns to a small state, the first weir plate 310 and the second weir plate 320 are restored to the closed state again through the hydraulic buffer automatic rebounder 340.

[0048] The circulation unit 400 is arranged at the end of a ditch, such as a waterway entering a river, the end of a lake or a reservoir, or an assessment section.

[0049] The circulation unit 400 includes a submersible sewage pump 410, a pump pit 420, a circulation pipeline 430, a water quality detection device 440 and a drainage gate 450; the submersible sewage pump 410 is arranged in the pump pit 420,

[0050] The water quality detection device 440 is used to detect whether the water quality is qualified. If it is unqualified, the water in the river channel will be pumped to the upstream of the ditch through the submersible sewage pump 410 and the circulation pipe 430 for recirculation treatment until it meets the standard, and then the drainage gate 450 will be opened to discharge the water into the downstream of the river channel or lake.
