Description

Technical Field

[0001] The utility model belongs to the technical field of non-point source pollution control, and in particular relates to a non-point source pollution reduction channel. Background Art

[0002] Non-point source pollution, also known as non-point source pollution, is mainly composed of soil sediment particles, nutrients such as nitrogen and phosphorus, pesticides, various atmospheric particulate matter, etc. It enters the water, soil or atmospheric environment through surface runoff, soil erosion, farmland drainage, etc. It has the characteristics of randomness, extensiveness, hysteresis, ambiguity, and latency, which increases the difficulty of corresponding research and control.

[0003] The Chinese patent with publication number CN219929663U discloses a non-point source pollution reduction channel, including: a foundation, a ditch is opened inside the foundation, and a filter tank is opened on both sides of the top of the ditch; a filter plate is fixedly installed on the outer surface of the filter tank; a push component is arranged inside the filter tank, and the push component includes a push box, which is movably embedded inside the filter tank; a connecting rod is fixedly installed on the top of the push box; a support plate is fixedly connected to the top of the connecting rod; and a moving wheel is fixedly installed at the bottom of the support plate. However, when rainwater flows into the non-point source pollution reduction channel, especially when the rainwater is heavy, it is easy to bypass the filter component and flow directly into the ditch, resulting in some sewage not being filtered and incomplete filtration. In addition, non-point source pollution during rain is more serious in the early stage of rainfall. Rainwater carries many harmful substances and sediments in the non-point source pollution area into the ditch. As the rainfall continues, the pollutants that can be washed and dissolved in the non-point source pollution area gradually decrease, and the content of harmful substances entering the ditch also decreases. However, the amount of water purifier added in the above patent has not changed accordingly, which may cause insufficient amount added in the early stage to fully eliminate harmful substances, and excessive amount added in the later stage to reversely pollute the water quality.

[0004] To this end, a non-point source pollution reduction channel is proposed. Utility Model Content

[0017] When it rains, rainwater carrying non-point source pollution first enters the filter channels on both sides of the ditch, and then enters the ditch through the water outlet. Since there is an interception net at the water outlet, the interception net intercepts large particles of pollutants such as sand, gravel and garbage in the non-point source pollution in the filter channel, which is convenient for later cleaning and prevents large particles of pollutants from entering the ditch; when rainwater carrying non-point source pollution enters the filter channel, since the interception plate is higher than the ground, even when the water flow is turbulent, it is not easy for rainwater to cross the filter channel and enter the ditch directly.

The intercepted large particles of pollutants can be cleaned out of the filter channel by the cleaning component later to keep the filter channel unobstructed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Reference Figures 1 to 4 As shown, this embodiment provides a non-point source pollution reduction channel, including:

[0027] A ditch 1, interception plates 2 are fixedly connected to both sides of the ditch 1, a filtering channel 3 is provided on the side of the interception plate 2 away from the ditch 1, the bottom surface of the filtering channel 3 is higher than the bottom surface of the ditch 1, a plurality of water inlets 4 are provided on the interception plate 2, and interception nets 5 are fixedly connected to the outer sides of the water inlets 4, and the top of the interception plate 2 is higher than the ground;

[0028] A reagent delivery assembly is fixedly connected above the two intercepting plates 2, and the reagent delivery assembly is arranged corresponding to the ditch 1; a crossbeam 6 is erected above the ditch 1, and legs 7 are fixedly connected on both sides of the crossbeam 6, and feet 8 are fixedly connected to the bottom of the legs 7, and the feet 8 roll on the bottom surfaces of both sides of the ditch 1, and cleaning assemblies are fixedly connected to the two filter channels 3 on both sides below the crossbeam 6, and the cleaning assemblies are arranged corresponding to the filter channels 3.

[0029] When it rains, rainwater carrying non-point source pollution first enters the filter channel 3 on both sides of the ditch 1, and then enters the ditch 1 through the water inlet 4. Since the interception net 5 is set at the water inlet 4, the interception net 5 intercepts large particles of pollutants such as sand, gravel and garbage in the non-point source pollution in the filter channel 3, which is convenient for later cleaning and prevents large particles of pollutants from entering the ditch 1; when rainwater carrying non-point source pollution enters the filter channel 3, since the interception plate 2 is higher than the ground, even when the water flow is turbulent, it is not easy for rainwater to cross the filter channel 3 and directly enter the ditch 1. It will be blocked by the interception plate 2 and enter the filter channel 3 to be filtered. The filtered rainwater enters the ditch 1. A reagent delivery component is set above the ditch 1 to deliver water purifiers into the ditch 1 to eliminate nutrients such as nitrogen and phosphorus contained in the non-point source polluted water in the ditch 1 to prevent eutrophication of the water body. The intercepted large particles of pollutants can be cleaned out of the filter channel 3 by the cleaning component in the later stage to keep the filter channel 3 unobstructed.

[0030] According to a further optimization scheme, arc-shaped transition edges are provided at the connecting edges between the water outlet 4 and the ditch 1 and the connecting edges between the filter channel 3 and the ground.

[0031] The curved transition edge can make the water flow more gentle.

[0032] According to a further optimized solution, the reagent delivery assembly includes a reagent box 9, which is fixed above the two interception plates 2. A plurality of reagent compartments 10 are arranged at intervals in the reagent box 9, and a reagent tube 11 is connected to the bottom of each reagent compartment 10.

[0033] Different reagents can be placed in the reagent compartments 10 in the reagent box 9, corresponding to the digestion of different nutrient-rich substances.

[0034] According to a further optimization scheme, a water quality detector 12 is fixedly connected to the front side of the reagent box 9 , the water quality detector 12 is electrically connected to the control center 13 , and the water quality detector 12 includes a water quality detection probe 14 , which extends into the bottom of the ditch 1 .

[0035] The water quality detector 12 is preferably a continuous flow analysis (CFA) instrument, a flow injection analysis (FIA) instrument, a nuclear magnetic resonance (NMR) spectrometer or other instrument that can perform real-time detection; the water quality detector 12 detects the pollutant content in the water flow and transmits the detection data to the control center 13, and the control center 13 collects and processes the data.

[0036] To further optimize the solution, a flow valve 15 is provided on the reagent tube 11 , and the flow valve 15 is electrically connected to the control center 13 .

[0037] After the control center 13 receives the signal of the pollutant content in the water body, it processes and analyzes the signal, calculates the amount of each reagent in the reagent box 9 according to the content of different eutrophic substances in the water body, and then converts the information into an electrical signal to control the flow valve 15 to control the flow of the flow valve 15, and then controls the amount of different reagents to achieve the purpose of accurately eliminating eutrophic substances.

[0038] To further optimize the solution, the cleaning assembly includes a cleaning box 16, one end of which is open and the opening is inclined, and the cleaning box 16 is arranged corresponding to the filter channel 3; two hydraulic telescopic rods 17 are hinged on the top of the cleaning box 16, and the tops of the two hydraulic telescopic rods 17 are slidably connected to the crossbeam 6.

[0039] The cleaning box 16 first moves downward corresponding to the filtering channel 3. At this time, the two hydraulic telescopic rods 17 are at the same height and extend and retract together until the bottom of the cleaning box 16 touches the bottom surface of the filtering channel 3, and then pushes the crossbeam 6 to move forward. The cleaning box 16 can collect large particles of garbage and impurities accumulated in the filtering channel 3 into the inner cavity, and then the two hydraulic telescopic rods 17 move upward together to take the impurities out of the filtering channel 3, and then translate the two hydraulic telescopic rods 17 to above the ground, and then the hydraulic telescopic rod 17 on the opening side is expanded, and the hydraulic telescopic rod 17 on the rear side is contracted, so that the opening of the cleaning box 16 is rotated downward, and then the impurities in the cleaning box 16 are poured out;

[0040] Furthermore, a receiving box may be provided below the cleaning box 16 for receiving large particles of pollutants.

[0041] To further optimize the solution, a slider 18 is fixedly connected to the top of the hydraulic telescopic rod 17, and the two sliders 18 located on the same side of the ditch 1 are connected by a connecting plate 19; the slider 18 is slidably connected to a slide groove 20, and the top of the slide groove 20 is fixedly connected to the bottom of the beam 6, and a screw 21 is rotatably connected in any of the two slide grooves 20 located on the same side of the ditch 1, and the screw 21 is threadedly connected to the slider 18 in the slide groove 20, and one end of the screw 21 extends out of the slide groove 20 and is transmission-connected to the output end of the motor 22, and the motor 22 is fixed to the beam 6.

[0042] The motor 22 drives the screw rod 21 to rotate, so that the slider 18 threadedly connected to the screw rod 21 slides in the slide groove 20, and drives the other slider on the same side to slide in its slide groove 20 through the connecting plate 19, so that the two hydraulic telescopic rods 17 fixed to the slider 18 are simultaneously close to or away from the ditch 1, so that the cleaning box 16 fixed under the hydraulic telescopic rod 17 can be translated back and forth on the ground and above the filter channel 3.

[0043] To further optimize the solution, a cleaning brush 23 is fixedly connected to the bottom of one side of the cleaning box 16 close to the interception net 5.

[0044] The cleaning brush 23 can brush the filter screen on one side of the filter channel 3 when the cleaning box 16 is lowered or raised corresponding to the filter channel 3, and can clean some impurities such as dirt attached to the filter screen to maintain good water permeability of the filter screen.
