Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically to a wastewater purification device for seed soaking and germination. Background Technology

[0002] Seed soaking and germination is a common technique in agricultural production, mainly used to promote seed germination. This process typically involves soaking seeds in water or other solutions for a period of time to soften the seed coat and activate the seed's internal enzyme system. Germination is further promoted by controlling conditions such as temperature, humidity, and light.

[0003] During the seed soaking and germination process, a certain amount of wastewater is generated due to the use of water and other chemicals (such as disinfectants and nutrient solutions). This wastewater mainly includes organic matter adhering to the seed surface, nutrient solution, pesticide residues, disinfectants, seed shell fragments, and soil particles. Existing wastewater treatment devices use multiple separation processes to separate the water and mud components from the wastewater. Current wastewater treatment methods require the addition of various treatment agents in multiple treatment steps to precipitate impurities in the wastewater. However, during these multiple treatment steps, some agents are discharged or precipitated before fully contacting the pollutants, leading to agent waste and increased treatment costs. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater purification device for seed soaking and germination, which improves the utilization rate of the agent, reduces agent waste, and lowers the treatment cost.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A wastewater purification device for seed soaking and germination includes a treatment tank, in which a coagulation tank, a flocculation tank, a reaction tank, and a sedimentation tank are arranged sequentially. An inlet pipe is installed at the top of the outer wall of the coagulation tank. A first connecting port is formed between the bottom sidewalls of the coagulation tank and the flocculation tank. A second connecting port is formed between the top sidewalls of the flocculation tank and the reaction tank. A third connecting port is formed between the bottom sidewalls of the reaction tank and the sedimentation tank. A drain pipe is installed at the top of the outer wall of the sedimentation tank. A suction pipe is connected to the bottom of the outer wall of the sedimentation tank. A feed pipe is connected to the bottom of the outer wall of the coagulation tank. A three-way valve is connected between the feed pipe and the suction pipe. A sewage pipe is also connected to the three-way valve. A first on / off valve and a second on / off valve are respectively installed on the sewage pipe and the feed pipe. A delivery pump is installed on the suction pipe.

[0007] Furthermore, the bottom of the coagulation tank, flocculation tank, and reaction tank are all equipped with a stirring mechanism.

[0008] Furthermore, the stirring mechanism includes a rotating shaft rotatably disposed inside the processing tank, a drive motor for driving the rotating shaft to rotate is installed on the outside of the processing tank, and a stirring rod is fixedly connected to the rotating shaft.

[0009] Furthermore, a sludge collection pipe is provided at the bottom of the sedimentation tank, the sludge collection pipe is connected to the material extraction pipe, and multiple collection branch pipes are installed on the sludge collection pipe.

[0010] Furthermore, inclined tube packing is provided in the middle of the inner side of the sedimentation tank.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention uses a three-way valve to connect the injection pipe and the extraction pipe, allowing the settled sludge after multiple processing steps to be reintroduced into the coagulation tank. This reflux design ensures that unreacted reagents can participate in the treatment again, improving reagent utilization, reducing reagent waste, and lowering treatment costs.

[0015] like Figure 1As shown, a wastewater purification device for seed soaking and germination includes a treatment tank 1. The treatment tank 1 contains, in sequence, a coagulation tank 101, a flocculation tank 102, a reaction tank 103, and a sedimentation tank 104. An inlet pipe 2 is installed at the top of the outer side wall of the coagulation tank 101. A first connecting port 105 is provided between the bottom side walls of the coagulation tank 101 and the flocculation tank 102. A second connecting port 106 is provided between the top side walls of the flocculation tank 102 and the reaction tank 103. The reaction tank 103 and the sedimentation tank 104... A third connecting port 107 is provided between the bottom side walls. A drain pipe 3 is provided at the top of the outer side wall of the sedimentation tank 104. A material extraction pipe 4 is connected to the bottom of the outer side wall of the sedimentation tank 104. A material injection pipe 5 is connected to the bottom of the outer side wall of the coagulation tank 101. A three-way valve 6 is connected between the material injection pipe 5 and the material extraction pipe 4. A sewage pipe 7 is also connected to the three-way valve 6. A first shut-off valve 8 and a second shut-off valve 9 are respectively installed on the sewage pipe 7 and the material injection pipe 5. A conveying pump 10 is installed on the material extraction pipe 4.

[0016] The bottom of the coagulation tank 101, flocculation tank 102 and reaction tank 103 are all equipped with stirring mechanisms.

[0017] The stirring mechanism includes a rotating shaft 11 rotatably disposed inside the processing tank 1. A drive motor for driving the rotating shaft 11 to rotate is installed on the outside of the processing tank 1. A stirring rod 12 is fixedly connected to the rotating shaft 11.

[0018] The bottom of the sedimentation tank 104 is provided with a sludge collection pipe 13, which is connected to the material extraction pipe 4, and multiple collection branch pipes 14 are installed on the sludge collection pipe 13.

[0019] Inclined tube packing is provided in the middle of the inner side of the sedimentation tank 104.

[0020] Working principle:

[0021] Wastewater generated during the seed soaking and germination process enters the coagulation tank 101 through the inlet pipe 2. Carbon powder is added to the coagulation tank, utilizing its pores to absorb and degrade the turbidity and color of the wastewater. A stirring mechanism ensures thorough mixing of the wastewater and carbon powder. The treated wastewater then enters the flocculation tank 102 through the first connecting port 105. In the flocculation tank 102, polyaluminum chloride is further added, causing fine colloidal particles to form larger flocs, which are used to remove suspended solids, colloids, and some dissolved organic matter from the water. The stirring mechanism ensures full contact between the polyaluminum chloride and the wastewater. The treated wastewater then enters the reaction tank 103 through the second connecting port 106. A demulsifier is added to the reaction tank 103, which rapidly settles the suspended flocs into flocculated aggregates, thus removing water and pollutants. The separation and stirring mechanism ensures that the reaction proceeds fully. The treated wastewater enters the sedimentation tank 104 through the third connection port 107. In the sedimentation tank 104, the sediment in the wastewater gradually settles to the bottom, forming sludge. The upper layer of clear water is discharged from the system through the drain pipe 3. The inclined tube packing can reduce the interference of water flow, which helps to improve the sedimentation efficiency and ensure that the water quality meets the standards. The sludge at the bottom of the sedimentation tank 104 is pumped to the three-way valve 6 by the conveying pump 10 through the collection branch pipe 14, the sludge collection pipe 13 and the material extraction pipe 4. The first shut-off valve 8 is closed and the second shut-off valve 9 is opened. The sludge is reinjected into the coagulation tank 101 for further treatment. When there is a lot of sludge in the system, the first shut-off valve 8 is opened and the second shut-off valve 9 is closed. The sludge is discharged from the system through the sewage pipe 7.

[0022] This invention improves the utilization rate of chemicals and reduces chemical waste through sludge recirculation design.
