Description

Technical Field

[0001] The invention relates to the technical field of non-point source pollution restoration and management, and provides a non-point source pollution ecological restoration and management device and an application method. 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 particles, etc., which enter the water, soil or atmospheric environment through surface runoff, soil erosion, farmland drainage, etc. Its randomness, extensiveness, hysteresis, ambiguity, and latency have increased the difficulty of corresponding research, governance, and management policy formulation.

[0003] Non-point source pollution refers to the dissolve and solid pollutants from non-specific locations, which are washed by precipitation (or snowmelt) and flow into receiving water bodies (including rivers, lakes, reservoirs and bays, etc.) through the runoff process, causing eutrophication or other forms of pollution. Compared with point source pollution, non-point source pollution is mainly caused by surface soil sediment particles, nutrients such as nitrogen and phosphorus, harmful substances such as pesticides, solid waste such as straw and agricultural film, livestock and poultry manure and sewage, aquaculture bait and drugs, rural domestic sewage and garbage, and various atmospheric particulate matter precipitation, which enter the water environment through surface runoff, soil erosion, farmland drainage, etc. It has the characteristics of dispersion, concealment, randomness, latency, accumulation and ambiguity, so it is not easy to monitor and quantify, and it is difficult to study and prevent and control.

[0004] Water pollution is a major disaster area for non-point source pollution, and it is also an area that is easily ignored by society. The quality of water in the natural environment has a great impact on the normal production and life of agriculture. For example, in the process of agricultural production, a considerable part of agricultural water comes from rivers and lakes. In the process of fishery breeding, it basically comes from natural water bodies. Therefore, the quality of water in nature has a great impact on human production and life, which makes the management of water sources in the natural environment more urgent.

[0005] Large water bodies in the natural environment, such as wider rivers or lakes, have complex and changeable coastal terrain. Under the influence of wind direction and water flow, pollutant accumulation areas with poor fluidity are often formed on the shore. Various duckweed, debris, etc. gather, causing local water quality to deteriorate, which in turn affects the water quality of the entire water area. Summary of the invention

[0006] The purpose of the present invention is to address the deficiencies of the prior art and to propose an ecological restoration and treatment device for non-point source pollution and an application method to solve the following technical problems: (1) the cost of restoration and treatment of large water bodies is high and the treatment is difficult; (2) it is difficult to achieve long-term and continuous treatment and restoration of natural water bodies; and (3) pollutants accumulate locally in large natural water bodies and the water quality is poor.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a non-point source pollution ecological restoration and control device, including a pontoon assembly, a filter tank, a water inlet tank and a pump tank are connected in sequence below the pontoon assembly; the pontoon assembly is provided with a clean water tank, and the outer periphery of the clean water tank is provided with a ring-shaped pontoon, a water outlet pipe, a battery tank and a control tank in sequence from bottom to top, a photovoltaic panel is provided on the top surface of the clean water tank, the bottom of the clean water tank is connected with the filter tank, and the water outlet pipe is connected with the clean water tank; the filter tank is used to accommodate the filter medium, and the bottom of the filter tank is connected with the water inlet tank; the water inlet tank is used to connect a water pump, and a joint is provided at the bottom of the water inlet tank, which is connected to the water outlet of the water pump; the pump tank is used to install a water pump.

[0011] Furthermore, the filter bin, water inlet bin and pump bin are bin bodies with open tops; wherein the bottom of the filter bin is hollowed out for carrying the filter medium; a joint is provided at the bottom of the water inlet bin for connecting a water pump; and the outer wall of the pump bin is mesh-shaped.

[0012] Furthermore, the connections between the clean water tank, the filter tank, the water inlet tank and the pump tank are respectively provided with internal and external threads, and the tanks are threadedly sealed.

[0013] Furthermore, there may be several filter chambers, in which different filter media may be placed according to water conditions and treatment requirements.

[0015] Furthermore, the filter medium is sponge, activated carbon, biochemical cotton, bioceramic or sand.

[0016] Furthermore, a method for applying a non-point source pollution ecological restoration and management device is provided. When the device is used, the number of devices to be deployed is determined according to the size of the water body, and then the devices are directly deployed in the water body that needs to be restored and managed.

After it is full, place another filter screen 201 on the top of the filter medium to isolate different filter media. The number of filter chambers 2 required is determined based on the water pollution status and upright repair requirements.

[0024] The pump compartment 4 is a mesh structure, which is used to filter out large debris in the water to prevent the water pump 401 from getting stuck. The water pump 401 is placed in the water through the pump compartment 4, which is beneficial to the heat dissipation of the motor.

[0025] The photovoltaic panel 101 converts solar energy into electrical energy, and under the control of the photovoltaic controller, transmits the electrical energy to the battery for storage.
