Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, and specifically relates to a large-flow river and lake water purification device. Background Art

[0002] The water quality problems of rivers, lakes and rain-sewage mixed water bodies have always been the focus of environmental protection and water resource management. SS (suspended solids), TP (total phosphorus), and COD (chemical oxygen demand) are important indicators for measuring the degree of water body pollution. The increase of these indicators usually means that the water body is polluted, affecting the ecological health and use value of the water body.

[0003] Traditional water purification methods include physical sedimentation, chemical flocculation, biological treatment, etc. Physical sedimentation mainly relies on gravity to remove suspended solids in water. Chemical flocculation makes the suspended substances in water aggregate into large particles by adding flocculants, which is convenient for sedimentation. Biological treatment uses the metabolic action of microorganisms to decompose organic pollutants in water.

[0004] In order to effectively reduce indicators such as SS, TP, and COD, improve the transparency of the water body, and inhibit the outbreak of algae, modern water purification technology equipment usually adopts the comprehensive application of multiple technologies. For example, integrating membrane technologies such as microfiltration, ultrafiltration, and reverse osmosis can effectively remove suspended solids and dissolved pollutants in water. At the same time, combining ultraviolet disinfection or ozone oxidation technology can further degrade organic pollutants and inhibit the growth of algae.

[0005] There is an urgent need to design a purification device for large-flow river and lake water bodies to improve the water treatment efficiency, reasonably allocate the use of chemical agents, reduce the floor area of the device, and reduce the interference to the water body ecology.

Specific embodiments

[0020] To make the purpose, principle and structure of the present utility model clearer, the following further elaborates with reference to the attached drawings and specific embodiments.

[0021] See Figures 1-3 , the present utility model provides a large - flow river and lake water purification device, including: a water inlet module 1, a micro - flocculation module 2 and a filtration and purification module 3.

[0022] The water inlet module 1 includes a water inlet pipe and a lifting system. The lifting system includes a water pump and a check valve, and is used to pump the water to be treated (river and lake water or rain - sewage mixed water) into the device.

[0023] The micro - flocculation module 2 includes: an equipment box body 12, a box door 14, a step ladder 15 and a chemical dosing device.

[0024] On one side inside the equipment box body 12, a pipe rack 7 is provided. Inside the pipe rack 7, there is a coagulation pipeline 6 that rotates in a spiral shape from top to bottom in multiple circles. The number of rotation circles of the coagulation pipeline is 4 - 6 circles. One end at the bottom of the coagulation pipeline 6 is provided with a water inlet 4 for introducing the water to be treated. The water inlet 4 is provided with a flange for conducting connection with the end of the water inlet pipe. Inside the coagulation pipeline 6 at one end of the water inlet 4, a flow meter 5 is provided for detecting the liquid flow rate and velocity in the coagulation pipeline 6.

[0025] The chemical dosing device consists of a chemical agent barrel 8, a chemical dosing metering pump 9, a stirring motor 10, and a stirring paddle 11. The chemical dosing device is connected to the water inlet pipe through a chemical dosing pipeline. The other end of the chemical dosing pipeline is arranged inside the chemical agent barrel 8. A chemical dosing metering pump 9 is also provided on the side of the chemical dosing pipeline close to the chemical agent barrel 8. The chemical dosing metering pump 9 is used to pump the flocculating agent in the chemical agent barrel 8 into the coagulation pipeline 6 through the chemical dosing pipeline. A stirring motor 10 is provided on the lid of the chemical agent barrel 8. The lower end of the stirring motor 10 is connected to the stirring paddle 11. The stirring paddle passes through the lid of the chemical agent barrel 8 and extends into the chemical agent barrel 8. The rotation of the stirring paddle 11 can be realized by the drive of the stirring motor 10, so as to fully stir the chemical agent in the chemical agent barrel 8. An electrical control cabinet 12 is also arranged inside the equipment box body 13. A box door 14 and a downward-extending ladder 15 are arranged on one side of the box body for staff to enter the equipment box body 13 for maintenance and daily maintenance work.

[0026] A filter purification module 3 is also provided at the bottom of the equipment box body 13. The filter purification module 3 is communicated with the bottom outlet end of the coagulation pipeline 6. The filter purification module 3 includes a filter bag 16, a maintenance door 17, and a water outlet 18. After the coagulation pipeline 6 fully coagulates the water body to be purified and the flocculating agent, the coagulated water body is discharged into the filter bag 16. The filter bag 16 filters and captures the water body impurities after coagulation precipitation. The water body after filtration penetrates out of the filter bag 16 and is discharged through the water outlet 18. The maintenance door 17 is used for staff to enter the device for maintenance.

[0027] The specific working principle is as follows.

[0028] The water body to be purified is input into the micro-flocculation module 2 under the action of the water inlet module 1. The water body to be purified enters the coagulation pipeline 6 through the water inlet 4. The flowmeter 5 dynamically adjusts the flocculating agent required for coagulation by detecting the flow rate of the water body to be purified injected through the water inlet 4. The flocculating agent is transported to the water inlet 4 through the chemical dosing pipeline under the action of the chemical dosing metering pump 9 and is mixed with the water body to be purified.

[0029] The mixed water body is lifted to the highest point of the coagulation pipeline 6 under the action of the pressure at the water inlet 4, and then gradually falls along the coagulation pipeline 6 in a "return" shape. During the process, the mixed water body will generate a large kinetic energy under the action of the gravitational potential energy difference, so that the mixed water body fully impacts the pipeline wall in the coagulation pipeline 6 to achieve full mixing. And because the pipeline is designed in a spiral "return" shape, the mixed water body will generate a centrifugal force under the action of inertia to separate large particle floc impurities. During this period, the stirring paddle 11 in the chemical agent barrel 8 always stirs to maintain the activity of the flocculating agent and prevent precipitation.

[0030] The coagulated water after passing through the coagulation pipeline 6 will be discharged into the filter bag 16. The filter bag 16 captures the flocculated impurities in the water body. The filtered water body penetrates from the filter bag 16 and is finally discharged through the water outlet 18.

[0031] The above is only the specific implementation manner of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by this utility model, according to the technical solution of this utility model and the new concept, makes equivalent replacements or changes, and should be covered within the protection scope of this utility model.
