[0002] Aquaculture refers to the production activity of breeding and growing aquatic organisms such as fish, shellfish, shrimp, and crabs in an artificially controlled environment for economic gain through the provision of bait and water quality control. Aquaculture can be divided into two major categories: freshwater aquaculture and marine aquaculture. Common species include carp, grass carp, tilapia, shrimp, and scallops. During the aquaculture process, the aquaculture water used after use often contains pollutants such as suspended solids, organic matter, ammonia nitrogen, nitrite, phosphate, and pathogenic microorganisms. If untreated aquaculture effluent is directly discharged, it will seriously pollute the water, affecting aquatic ecosystems and leading to problems such as eutrophication and algae blooms.

[0003] Methods for treating aquaculture tailwater include various technologies such as physical treatment, chemical treatment and biological treatment. However, the existing processes for purifying aquaculture tailwater have problems such as large footprint and low treatment efficiency, which leads to increased breeding costs and fails to achieve the expected results.

[0021] Unless stated otherwise or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] It should be noted that, in this document, “fixed to” or “connected to” may mean directly fixing or connecting to an element, or indirectly fixing or connecting to an element.

[0023] like Figure 1-2As shown, this embodiment provides an integrated sewage treatment device comprising a housing 1, which includes a treatment chamber 11 and a control chamber 12. Multiple treatment units are integrated into the housing 1, reducing floor space. The treatment chamber 11 is provided with a pretreatment tank 2, a biological treatment tank 3, a sedimentation tank 4, a sludge separation tank 5, and a disinfection tank 6, sequentially arranged along the sewage treatment flow direction. The pretreatment tank 2 is provided with an inlet pipe connected to the aquaculture tank, and the disinfection tank 6 is provided with an outlet pipe connected to the aquaculture tank. The tail water from the aquaculture pond flows into the pretreatment tank 2, which is a screen. The pretreatment tank 2 removes large particles of impurities and suspended solids from the aquaculture tail water; the tail water treated in the pretreatment tank 2 enters the biological treatment tank 3, which is a biological filter. The filler is used to provide a surface for the attachment of the biofilm. The biological treatment tank 3 degrades organic matter and ammonia nitrogen in the aquaculture tail water; the tail water treated in the biological treatment tank 3 enters the sedimentation tank 4, which separates the sludge in the aquaculture tail water by gravity sedimentation; the sludge obtained in the sedimentation tank 4 is concentrated and decomposed in the sludge separation tank 5 to form an upper layer of liquid and a lower layer of concentrated sludge; the tail water treated in the sedimentation tank 4 and the tail water flowing out of the sludge separation tank 5 enter the disinfection tank 6, which is equipped with an ultraviolet disinfector to kill pathogenic microorganisms in the aquaculture tail water; the tail water after disinfection is returned to the aquaculture pond for aquaculture, effectively reducing the consumption of fresh water, saving water resources, reducing aquaculture costs, and improving economic benefits.

[0024] In this embodiment, a partition plate 53 is provided inside the sludge separation tank 5, which divides the sludge separation tank 5 into a first separation chamber 51 and a second separation chamber 52. A mounting frame 512 is slidably mounted inside the first separation chamber 51. A filter cloth 514 is mounted at the bottom of the mounting frame 512. A reciprocating screw 516 is mounted on the top of the mounting frame 512. The reciprocating screw 516 is connected to a motor 515. A slider 517 is sleeved on the outer surface of the reciprocating screw 516. A squeezing roller 518 is mounted at the bottom of the slider 517. The squeezing roller 518 abuts against the filter cloth 514. When the motor 515 is started, the motor 515 drives the reciprocating screw 516 to rotate, causing the slider 517 to drive the squeezing roller 518 to move along the reciprocating screw 516. The squeezing roller 518 squeezes the filter cloth 514, squeezing out moisture from the filter cloth 514 and squeezing the sludge below the filter cloth 514, thereby improving the efficiency of sludge treatment and water recovery.

[0025] In this embodiment, the upper end of the partition plate 53 is provided with a through hole 531 connecting the first separation chamber 51 and the second separation chamber 52. The upper layer of liquid in the first separation chamber 51 passes through the filter cloth 514, enters the mounting frame 512, and is discharged through the through hole 531 to the second separation chamber 52. This achieves a certain degree of compartmentalized storage of the concentrated sludge and liquid in the sludge separation tank 5. Within the first separation chamber 51, gravity forces the mounting frame 512 to push the filter cloth 514 downward, squeezing the sludge. This compresses the lower layer of sludge, compacting it and allowing moisture to seep out further, further improving water recovery efficiency.

[0026] In this embodiment, a sludge discharge pipe 41 is provided at the bottom of the sedimentation tank 4, communicating with the bottom of the first separation chamber 51 of the sludge separation tank 5. This pipe transports the sludge processed in the sedimentation tank 4 to the first separation chamber 51. The sludge is concentrated and decomposed within the first separation chamber 51, forming an upper layer of liquid and a lower layer of concentrated sludge, thereby reducing the sludge volume. A regulating valve 42 is installed on the sludge discharge pipe 41, and sludge discharge is achieved by opening the regulating valve 42.

[0027] In this embodiment, a limit plate 511 is installed on the inner side wall of the first separation room 51. The limit plate 511 is located below the mounting frame 512 and limits the sliding displacement of the mounting frame 512.

[0028] In this embodiment, a sealing ring 513 is installed on the side wall of the mounting frame 512. The sealing ring 513 provides a good sealing effect to prevent sludge from seeping out.

[0029] In this embodiment, a first water pipe 111 is provided on the upper part of the pretreatment tank 2 to connect to the biological treatment tank 3, a second water pipe 112 is provided on the upper part of the biological treatment tank 3 to connect to the sedimentation tank 4, a third water pipe 113 is provided above the sedimentation tank 4 to connect to the disinfection tank 6, and a fourth water pipe 114 is provided on the upper part of the second separation room 52 to connect to the disinfection tank 6.

[0030] In this embodiment, the bottom of the sedimentation tank 4 is funnel-shaped, and the funnel-shaped bottom of the sedimentation tank 4 is conducive to the sedimentation of sludge.

[0031] Working principle: The tail water from the aquaculture pond flows into the pretreatment tank 2, which removes large particles of impurities and suspended solids in the aquaculture tail water; the tail water treated in the pretreatment tank 2 enters the biological treatment tank 3, which degrades organic matter and ammonia nitrogen in the aquaculture tail water; the tail water treated in the biological treatment tank 3 enters the sedimentation tank 4, and the funnel-shaped bottom of the sedimentation tank 4 is conducive to the sedimentation of sludge. The sedimentation tank 4 separates the sludge in the aquaculture tail water by gravity sedimentation.

[0032] The sludge collected in the sedimentation tank 4 is passed into the first separation chamber 51 of the sludge separation tank 5. The motor 515 is activated, driving the reciprocating screw 516 to rotate. This causes the slider 517 to move the squeeze roller 518 along the reciprocating screw 516. The squeeze roller 518 squeezes the filter cloth 514, squeezing out the moisture within it and simultaneously squeezing the sludge beneath it. This squeeze compacts the lower layer of sludge, allowing further moisture to seep out. When the upper layer of liquid in the first separation chamber 51 reaches the through-hole 531 at the upper end of the partition plate 53, it flows through through-hole 531 into the second separation chamber 52, separating the lower layer of concentrated sludge and the upper layer of liquid in the sludge separation tank 5. The treated tailwater from the sedimentation tank 4 and the tailwater from the second separation chamber 52 enter the disinfection tank 6, where pathogenic microorganisms are killed. The disinfected tailwater then flows back to the aquaculture pond for use in aquaculture.

[0033] The control room 12 performs remote monitoring and automatic adjustment to reduce the complexity and labor intensity of manual operations.
