Description

Technical Field

[0001] This invention relates to the technical field of wastewater treatment devices for aquatic product processing, and particularly to a collaborative multi-stage deep treatment device for wastewater from aquatic product processing. Background Technology

[0002] Aquatic product processing (such as slaughtering, gutting, cleaning, freezing, and canning of fish, shrimp, and shellfish) generates a large amount of wastewater. This wastewater contains a large amount of protein, fat, blood, and visceral residues, resulting in a chemical oxygen demand (COD) of 1000-5000 mg / L and a biochemical oxygen demand (BOD) of 500-2500 mg / L, far exceeding that of ordinary domestic sewage. Direct discharge of this wastewater would severely deplete dissolved oxygen in the water, causing algal blooms or black and smelly conditions, and resulting in water pollution. When treating aquatic product processing wastewater, larger impurities and waste are often filtered out by screens. The pretreated wastewater is then transported to a multi-stage deep wastewater treatment device for multi-stage filtration. Existing multi-stage advanced treatment devices for aquatic product processing wastewater cannot quickly mix pretreated wastewater and chemical additives according to actual treatment needs, thus affecting the stability of the entire multi-stage advanced treatment process. Uneven mixing during the wastewater treatment stage leads to pollutant residues, which exacerbates fluctuations in the influent water quality of subsequent physicochemical treatment units, thereby impacting the efficiency and quality of wastewater treatment.

Under the subsequent aeration, physicochemical synergistic wastewater treatment is achieved, thereby improving the efficiency of wastewater treatment. Equipped with a base plate, inlet pipe, mixing mechanism, reciprocating lifting mechanism, aeration mechanism, quartz sand filter plate, and activated carbon filter plate, the pre-treated aquatic product processing wastewater is stably and continuously transported to the inlet pipe through the drain valve. The impeller can rotate along the inlet pipe, driving the convex rod to slide along the movable groove, which can cause the transmission gear to rotate back and forth, driving the agitator to reciprocate and mix the wastewater and chemical agents in the primary treatment tank, thereby improving the efficiency of mixing and treating wastewater and chemical agents and improving the quality of wastewater treatment.

A sleeve block 632 is movably connected to the outer wall of the protruding rod 631. A movable groove is provided inside the sleeve block 632. 633, a receiving frame 634 is fixedly connected to the outer wall of the sleeve block 632. A rack 64 is fixedly connected to the bottom of the receiving frame 634. A T-shaped slider 641 is fixedly connected to the bottom of the rack 64. A transmission gear 65 is movably connected to the outer wall of the rack 64. A second rotating rod 66 is fixedly connected to the bottom of the transmission gear 65. A docking post 67 is fixedly connected to the bottom of the second rotating rod 66. A third rotating rod 68 is movably connected to the outer wall of the docking post 67. A stirring paddle 69 is fixedly connected to the outer wall of the third rotating rod 68. The impeller 62 forms a rotating structure with the water inlet pipe 5 through the first rotating rod 61. The turntable 63 is connected to the water inlet pipe 5 through the first rotating rod 61. The structure comprises a rotating structure, with the convex rod 631 forming a sliding structure with the sleeve block 632 via the movable groove 633. The receiving frame 634 is L-shaped, and the T-shaped slider 641 forms a sliding structure with the support frame 3 via the T-shaped sliding groove 4. The rack 64 meshes with the transmission gear 65, which forms a rotating structure with the support frame 3 via the second rotating rod 66. The stirring paddle 69 forms a rotating structure with the support frame 3 via the third rotating rod 68, which has a slotted design. The third rotating rod 68 forms a sliding structure with the docking column 67, and a reciprocating lifting mechanism 7 is installed on the outer wall of the third rotating rod 68. The reciprocating lifting mechanism 7 includes components fixedly installed on... The guide protrusion 71 on the outer wall of the third rotating rod 68, the reciprocating lifting mechanism 7 includes a sleeve 72 fixedly installed at the bottom of the support frame 3, the sleeve 72 has a guide groove 73 inside, the reciprocating lifting mechanism 7 includes a rotating shaft 74 movably installed on the outer wall of the stirring paddle 69, the outer wall of the rotating shaft 74 is equipped with a movable plate 75, the stirring paddle 69 has a through hole 76 inside, the guide protrusion 71 and the sleeve 72 form a sliding structure through the guide groove 73, the sleeve 72 is movably connected to the third rotating rod 68, the movable plate 75 and the stirring paddle 69 form a rotating structure through the rotating shaft 74, the movable plate 75 is evenly distributed along the outer wall of the stirring paddle 69.

[0020] The pretreated aquatic product processing wastewater is stably and continuously transported to the inlet pipe 5 through the drain valve. The wastewater falls into the primary treatment tank 2 through the inlet pipe 5. During the transport, the wastewater impacts the impeller 62. Under the action of the first rotating rod 61, the impeller 62 can be rotated along the inlet pipe 5, causing the turntable 63 to rotate. This drives the convex rod 631 to slide along the movable groove 633 opened inside the sleeve block 632, causing the sleeve block 632 to move back and forth. This causes the rack 64 fixedly connected to the bottom of the receiving frame 634 to move back and forth. At this time, the T-shaped slider 641 slides back and forth along the T-shaped sliding groove 4 opened inside the support frame 3. Since the rack 64 is meshed with the transmission gear 65, under the action of the second rotating rod 66, the transmission gear 65 can be rotated back and forth, causing the docking column 6 to move back and forth. The third rotating rod 68, which is movably installed on the outer wall, reciprocates, driving the stirring paddle 69 to reciprocate and mix the wastewater and chemical agents in the primary treatment tank 2. As the third rotating rod 68 rotates forward and backward, the guide protrusion 71 can slide along the guide groove 73 opened inside the sleeve 72, so that the third rotating rod 68 can slide up and down along the sleeve 72 while rotating forward and backward, and the stirring paddle 69 can move up and down while rotating forward and backward. As the stirring paddle 69 moves up and down, the wastewater can enter through one end of the through hole 76 opened inside the stirring paddle 69 and exit from the other end, thereby generating bubbles. Under the action of the rotating shaft 74, the movable plate 75 can swing up and down along the stirring paddle 69, further mixing the wastewater and chemical agents.

The aeration mechanism 8 includes a movable rod 81 fixedly installed on the outer wall of the receiving frame 634, with a piston 82 fixedly connected to one end of the movable rod 81. The aeration mechanism 8 also includes an air cylinder 83 fixedly installed on the top of the support frame 3. A first one-way valve 831, a second one-way valve 832, a third one-way valve 833, and a fourth one-way valve 834 are installed on the outer wall of the air cylinder 83. An air supply pipe 84 is installed at the bottom of the cylinder 3. The piston 82 and the air cylinder 83 form a sliding structure. The input end of the air supply pipe 84 is connected to the first one-way valve 831 and the third one-way valve 833 respectively. The output end of the air supply pipe 84 is equipped with a first air delivery pipe 841. The output end of the first air delivery pipe 841 is equipped with a first flexible hose 842. One end of the first flexible hose 842 is fixedly connected to a set of aeration nozzles 843. The output end of the air supply pipe 84 is equipped with a second air delivery pipe 844. The output end of the second air delivery pipe 844 is equipped with a second flexible hose 843. 45. Two sets of aeration nozzles 846 are fixedly connected to one end of the second hose 845.

A set of aeration nozzles 843, a set of aeration nozzles 846, and a set of aeration nozzles 849 are arranged in a ring at equal intervals along the inner wall of the water supply pipe 85.

[0022] By reciprocating the receiving frame 634, the piston 82, fixedly connected to one end of the movable rod 81, can slide back and forth along the air cylinder 83. When the piston 82 slides to the right along the air cylinder 83, the first one-way valve 831 opens and the second one-way valve 832 closes. At this time, the third one-way valve 833 closes and the fourth one-way valve 834 opens, opening the first one-way valve 831 and supplying air to the air supply pipe 84. When the piston 82 slides to the left along the air cylinder 83, the fourth one-way valve 834 closes, causing the third one-way valve 833 to open and supply air to the air supply pipe 84, causing the output end of the air supply pipe 84 to continuously blow air, so that the four sets of aeration nozzles 843, two sets of aeration nozzles 846, and three sets of aeration nozzles 849 aerate the transported wastewater. The aeration process, combined with the spiral distribution of four aeration nozzles (group 843, group 846, and group 849) on the inner wall of the water supply pipe 85, creates a swirling flow in the wastewater during transport, further mixing the wastewater with the chemical agents. Since the output orifice diameters of the three aeration nozzles (group 843, group 846, and group 849) decrease progressively, the flow velocity of the wastewater gradually increases as it flows through the water supply pipe 85. This allows the wastewater to enter the secondary treatment tank 10 and impact the quartz sand filter plate 12. Under the dual filtration of the quartz sand filter plate 12 and the activated carbon filter plate 14, impurities in the wastewater are further filtered out. The multi-stage treated wastewater is then discharged through the drain pipe 11 to the next process stage.
