DETAILED DESCRIPTION

[0025] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0026] The integrated seawater breeding tail water treatment equipment is described below with reference to the drawings.

[0027] As Figures 1 to 3 shown, the integrated seawater breeding tail water treatment equipment can include: a frame 1 internally provided with an electrolysis area 11, a sedimentation area 12 and an ultrafiltration area 13.

[0028] It should be noted that the electrolysis area 11 and the ultrafiltration area 13 are located on both sides of the sedimentation area 12, the electrolysis area 11 is internally provided with an electric flocculation device 2, the sedimentation area 12 is internally provided with multiple inclined plates 3, and the bottom is provided with a sludge compaction device 4, and the ultrafiltration area 13 is internally provided with a fiber rotating disc device 5.

[0029] It can be understood that when the tail water enters the inside of the electrolysis area 11, it will be flocculated by the electric flocculation device 2 inside, when the flocculated tail water enters the sedimentation area 12, it will be flocculated and precipitated by the inclined pipe rapid precipitation principle, so that the sludge compaction device 4 compacts the flocculation, and the precipitated tail water will enter the inside of the ultrafiltration area 13 and be further filtered by the fiber rotating disc device 5, and the finally treated tail water is discharged through the fiber rotating disc device 5.

[0030] The electrolysis area 11 is provided with a water inlet 111 and a first water outlet 112 on both sides, wherein the water inlet 111 is higher than the first water outlet 112.

[0031] Specifically, the electric flocculation device 2 includes: an electrode plate 21 and a power supply 22.

[0032] It should be noted that the multiple electrode plates 21 are fixedly arranged in the electrolysis area 11, the power supply 22 is arranged on one side of the top of the electrolysis area 11 through a support plate, and the power supply 22 is connected with the multiple electrode plates 21 through the electrolysis area 11, and the multiple electrode plates 21 are connected in parallel on the power supply 22 power supply end.

[0033] It can be understood that the power supply 22 connects the multiple parallel electrode plates 21 to direct current, generates an electric field between the electrode plates 21, and makes the tail water to be treated enter the gap of the electrode plates 21 through the water inlet 111.

[0034] At this time, the electrified electrode plate 21 will undergo an electrochemical reaction, dissolve Al3+ or Fe2+ ions and hydrolyze in water to cause flocculation. In this process, electroflotation, oxidation and reduction and other effects occur at the same time. The results of these effects make the dissolved colloids and suspended pollutants in the water effectively transformed and removed.

[0035] The flocculation reaction can form flocculation by the adsorption effect of positive and negative charges of SS and heavy metals in the wastewater, and float on the water surface under the action of H gas and O gas generated by electrolysis, and separate from the water.

[0036] The HO radical ions and CL ions generated by electrolysis react with Na ions to form NaClO, which disinfects harmful bacteria in water, oxidizes organic matter in wastewater, removes COD, electrolyzes ammonia nitrogen to form ammonia gas and nitrogen gas, and forms nitrate nitrogen to achieve the purpose of removing ammonia nitrogen.

[0037] As shown in Figure 4 Figure 5 The integrated seawater aquaculture tail water treatment equipment, including: the bottom of the sedimentation zone 12 is provided with an isosceles trapezoidal sedimentation tank 121, the side wall of the sedimentation tank 121 is provided with an L-shaped baffle 122, the sludge compaction device 4 is arranged inside the sedimentation tank 121, and the L-shaped baffle 122 is located on one side of the first drain port 112.

[0038] It should be noted that the plurality of inclined plates 3 are respectively arranged at equal intervals inside the sedimentation zone 12, and the inclined plate 3 is directly above the first drain port 112.

[0039] It can be understood that the inclined plate 3 arranged inside the sedimentation zone 12 can make the flocculation in the tail water quickly precipitate, and the principle is to significantly increase the settling area of the particulate matter through the inclined plate or pipe, thereby accelerating the settling speed of the particulate matter.

[0040] It should be noted that the sludge compaction device 4 includes: a transmission gear 41, a strip-shaped tooth 42, a pressing block 43, a first driving motor 44 and a storage box 45, wherein the three transmission gears 41 are arranged on the side wall of the bottom of the sedimentation zone 12 and are concentrically provided with half gears 411 on the transmission gears 41 on both sides, the strip-shaped teeth 42 are respectively provided with tooth grooves on both sides, and the strip-shaped teeth 42 are respectively engaged with the two half gears 411, the two pressing blocks 43 are respectively arranged at both ends of the strip-shaped tooth 42, the first driving motor 44 is fixedly arranged on the side wall of the sedimentation zone 12 through a mounting frame, and the transmission end of the first driving motor 44 is connected with one of the transmission gears 41, and the two storage boxes 45 are respectively fixedly arranged on both sides of the sedimentation zone 12, and the internal space of the storage box 45 is matched with the pressing block 43.

[0041] It should be further noted that the sludge compaction device 4 is externally provided with a waterproof frame 6, and the waterproof frame 6 is provided with a through groove 61 matched with the pressing block 43 on both sides, the two pressing blocks 43 are respectively arranged inside the through groove 61, the two storage boxes 45 are respectively arranged on the sedimentation tank 121 on one side of the two pressing blocks 43, and the end of the storage box 45 away from the pressing block 43 is provided with a baffle 451.

[0042] It can be understood that when the first driving motor 44 is started, one of the transmission gears 41 is driven to rotate, thereby driving the other two transmission gears 41 engaged with it to rotate. Since the half gears 411 are arranged on the transmission gears 41 and are engaged with the strip-shaped teeth 42, when the transmission gears 41 rotate, the two half gears 411 drive the strip-shaped teeth 42 to make linear reciprocating motion, so that the pressing blocks 43 arranged at both ends of the strip-shaped teeth 42 push the flocculation deposited at the bottom into the storage box 45, and finally the flocculation is pressed into a cake shape as the flocculation accumulates.

[0043] As shown in Figure 2 The integrated seawater aquaculture tail water treatment equipment according to the embodiment of the utility model, including: the second drain 131 is opened in the sedimentation zone 12 one side of the ultrafiltration area 13, the second drain 131 and the sedimentation zone 12 interpenetration, and be at the top of the inclined plate 3.

[0044] It should be noted that the fiber rotating disc device 5 includes: a filter rotating disc 51, a water collecting cylinder 52, a backwashing device 53, a water suction pump 54 and a second driving motor 55, wherein a plurality of filter rotating discs 51 are fixedly arranged at equal intervals on the side wall of the water collecting cylinder 52, the water collecting cylinder 52 is rotatably arranged in the ultrafiltration area 13, and a plurality of through holes are arranged at equal intervals in the hollow side wall of the water collecting cylinder 52, a plurality of backwashing devices 53 are arranged on the plurality of filter rotating discs 510, the water suction pump 54 is connected to the plurality of backwashing devices 53 at the water inlet end, and the water outlet end is located in the sedimentation zone 12 at the bottom of the inclined plate 3, the second driving motor 55 is fixedly arranged on one side of the ultrafiltration area 13 through a mounting bracket, and the driving end of the second driving motor 55 is connected to the water collecting cylinder 52 through a synchronous belt.

[0045] It can be understood that when the water level in the sedimentation zone 12 reaches the second drain 131, the tail water enters the ultrafiltration area 13 through the second drain 131, at this time, the tail water is filtered by the filter rotating disc 51 and enters the water collecting cylinder 52, and finally the tail water purified by the water collecting cylinder 52 is discharged,

[0046] It can be further understood that when the flocculation on the filter rotating disc 51 accumulates too much, the backwashing device 53 is started (this is an existing structure and will not be described in detail here), so that the second driving motor 55 drives the water collecting cylinder 52 to rotate, thereby the water suction pump 54 sucks the flocculation on the filter rotating disc 51 through the backwashing device 53 and discharges it into the sedimentation zone 12 for re-deposition.
