Technical Field

[0001] This application relates to the technical field of wastewater treatment, and more particularly, to a wastewater treatment device. Background Art

[0002] Water treatment is a process of purifying water to meet the water quality requirements for discharging it into a certain water body or reusing it. During the water treatment process, many treatment devices are involved. According to different treatment environments, its processes generally include filtration, flocculation, aeration, etc. In industrial production in all walks of life, water treatment devices are essential.

[0003] Existing physical filtration generally uses a grid fence to intercept larger floating objects or debris in wastewater.

[0035] The present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.

[0036] Refer to Figures 1-6, A wastewater treatment device 100, comprising: a physical filtration tank 101, a biofilm filtration tank 102, a sterilization and disinfection tank 103, guide blocks 104, a grid fence 105, and a fixing component for fixing the grid fence 105 to the guide blocks 104. The sterilization and disinfection tank 103 is provided with a chlorine dioxide generator, which disinfects the effluent to ensure the stability and safety of the reclaimed water quality. A flat membrane is arranged in the biofilm filtration tank 102. The physical filtration tank 101 is connected to the biofilm filtration tank 102 through a water pipe, and the biofilm filtration tank 102 is connected to the sterilization and disinfection tank 103 through a water pipe.

[0037] There are two guide blocks 104, which are respectively located at both ends of the grid fence 105. The guide blocks 104 are fixedly connected to the physical filtration tank 101. The grid fence 105 is inserted into the guide blocks 104. Specifically, the guide blocks 104 are provided with installation grooves 104a, and a part of the grid fence 105 is located in the installation grooves 104a.

[0038] The fixing component is used to fix the grid fence 105 to the guide blocks 104, and includes: a first limiting rod 106, a baffle 107, a first slider 108, a second limiting rod 109, a fixing plate 110, and a first spring 112. The first limiting rod 106 is respectively inserted into the mounting plate and the grid fence 105. Specifically, the guide blocks 104 are provided with first limiting grooves 104b, and the grid fence 105 is provided with second limiting grooves 105a, and the first limiting rod 106 is respectively inserted into the first limiting grooves 104b and the second limiting grooves 105a. The baffle 107 is fixedly connected to the first limiting rod 106.

[0039] The first slider 108 is vertically slidably connected to the guide block 104. Specifically, the guide block 104 is provided with a first chute 104c extending along the height direction of the guide block 104, and the first slider 108 moves along the first chute 104c. The second limiting rod 109 is inserted into the first limiting rod 106. Specifically, the first limiting rod 106 is provided with a third limiting groove 106a, and the second limiting rod 109 is inserted into the third limiting groove 106a. The fixing plate 110 is fixedly connected to the guide block 104. The two ends of the first spring 112 are respectively fixedly connected to the fixing plate 110 and the first slider 108.

[0040] Among them, the second limiting rod 109 is located at one end of the first slider 108 and is fixedly connected to the first slider 108. The baffle 107 is located at one end of the first limiting rod 106, and the second limiting rod 109 is located at the other end of the first limiting rod 106. The fixing plate 110 is located at one end of the first spring 112, and the first slider 108 is located at the other end of the first spring 112. Insert the grid fence 105 into the installation groove 104a, push the first slider 108, and the movement of the first slider 108 drives the movement of the second limiting rod 109 (to make the first slider 108 approach the fixing plate 110), then insert the first limiting rod 106 into the first limiting groove 104b of the guiding block 104 and the second limiting groove 105a of the grid fence 105, and then release the first slider 108. Under the action of the first spring 112, the first slider 108 will reset, and the movement of the first slider 108 drives the movement of the second limiting rod 109, so that the second limiting rod 109 is inserted into the third limiting groove 106a of the first limiting rod 106, thereby fixing the grid fence 105 to the guiding block 104.

[0041] Workflow: The aquaculture wastewater is transported to the physical filtration tank 101, and larger floating objects or sundries in the wastewater are intercepted by the grid fence 105, and then the water is transported to the biofilm filtration tank 102. Through the efficient interception of the flat membrane, nitrifying bacteria can be effectively intercepted and completely retained in the biofilm filtration tank 102, enabling the nitrification reaction to proceed smoothly, effectively removing ammonia nitrogen, avoiding the loss of sludge, and at the same time, it can intercept macromolecular organic matter that is difficult to degrade for a while, extend its residence time in the biofilm filtration tank 102, and make it decomposed to the greatest extent. The suspended solids and turbidity of the produced water are nearly zero, and the water quality is good and stable. Then the water is transported to the disinfection tank 103, and the effluent is disinfected by a chlorine dioxide generator to ensure the stability and safety of the reclaimed water quality, and finally transported to the aquaculture pond, so as to achieve recycling. When it is necessary to replace or disassemble the grid fence 105, push the first slider 108, and the movement of the first slider 108 drives the movement of the second limiting rod 109, so that the second limiting rod 109 disengages from the third limiting groove 106a, and then take out the first limiting rod 106, and the grid fence 105 can be disassembled, and the disassembly is more convenient.
