Description

Technical Field

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

[0002] The suspended solids in aquaculture wastewater can be mainly divided into three types. The first type is the suspended solids with a relatively heavy mass, which are easy to precipitate at the bottom of the water body. Therefore, this type of suspended solids can generally be treated by gravity sedimentation. The second type is the suspended solids with a relatively light mass, which are easy to float on the water surface. Therefore, this type of suspended solids can generally be treated by simple means such as air flotation. The third type is the suspended solids with a mass between the first type and the second type.

[0077] As Figure 5 shown, further, the present application also provides a water treatment system 1. The water treatment system 1 includes the above water treatment device 10.

[0078] In one embodiment, the water treatment system 1 can be disposed in the water purification area 2. The water purification area 2 can be arranged near the source of the sewage (such as a breeding pond). The water purification area 2 is provided with a sewage treatment tank 3. The sewage treatment tank 3 can be disposed in the middle of the water purification area 2. The water to be treated can be centrally stored in the sewage treatment tank 3. The water treatment device 10 can be disposed on the bank of the water purification area 2 near the sewage treatment tank 3, that is, the water treatment device 10 is not directly disposed in the water body in the sewage treatment tank 3. When it is necessary to purify the water body by using the water treatment device 10, the user can convey the water body in the sewage treatment tank 3 to the reaction chamber 200 of the water treatment device 10 by means of a water conveyance device (such as a water pipe and / or a water pump) or by means of gravity flow, so that the water treatment device 10 can perform in-depth treatment on the water body. After the water treatment device 10 finishes the treatment, then the water discharged after the in-depth treatment by the water treatment device 10 is discharged to a designated position by means of a water conveyance device or by means of gravity flow.

[0079] As Figure 5 shown, further, the water treatment system 1 further includes an ecological purification device 20. The ecological purification device 20 is disposed in the water body in the sewage treatment tank 3 and is located at the upstream end of the water treatment device 10. The ecological purification device 20 is used to perform ecological treatment and biochemical treatment on the water body. Specifically, before the water body flows into the water treatment device 10, the ecological purification device 20 is used to perform ecological treatment and biochemical treatment on the water body in advance to remove the pollutants in the water body, thereby reducing the subsequent water treatment load of the water treatment device 10. Moreover, the ecological purification device 20 also has a good ecological landscape effect and can meet the landscape aesthetic requirements of the environment where the water purification area 2 is located.

[0080] As Figure 5 and Figure 6As shown, the ecological purification device 20 includes a first ecological substrate 21 and a second ecological substrate 22 arranged in sequence. In one embodiment, the first ecological substrate 21 includes an ecological floating island and a first auxiliary filler. The ecological floating island can be a PVC floating bed, which can float on the water surface. The top of the ecological floating island is used for planting floating island plants, and the floating island plants are used for ecological treatment of the water body. The first auxiliary filler is arranged at the bottom of the ecological floating island and extends into the water body. The first auxiliary filler is used for the attachment and growth of microorganisms, and the microorganisms are used for biochemical treatment of the water body to convert organic substances in the water body into inorganic substances.

[0081] In one embodiment, the floating island plants can directly absorb inorganic pollutants such as nitrogen and phosphorus in the water body through their own photosynthesis and release oxygen, thereby achieving the removal of inorganic substances in the water body. Moreover, the planting of the floating island plants can also play a role in beautifying the environment. In one embodiment, the floating island plants can be set as aquatic plants with nitrogen and phosphorus removal functions, such as canna, iris, pennywort, water sprite, softstem bulrush, water lily, etc., which can not only achieve the function of nitrogen and phosphorus removal in the water body and ensure the water quality of the effluent, but also improve the environmental landscape of the water body environment through reasonable design. In other embodiments, the floating island plants can also be economic crops, such as rice. Preferably, the first auxiliary filler can be made of an artificial polymer material that is friendly to the ecological environment. For example, the first auxiliary filler can be a non-woven fabric filler, a fiber filler or a composite filler, etc.

[0082] In one embodiment, the second ecological substrate 22 includes a floating bed and a second auxiliary filler. The floating bed can be, but is not limited to, a PVC floating bed, which can float on the water surface. The second auxiliary filler is arranged at the bottom of the floating bed and extends into the water body. The second auxiliary filler is used for cultivating algae plants and aquatic animals (such as fish, snails and shellfish that feed on aquatic plants). The algae plants can decompose inorganic substances in the water body through their own photosynthesis and release oxygen, thereby achieving the removal of inorganic substances in the water body. The floating bed provides a fixed-point support for the second auxiliary filler, enabling aquatic animals (such as fish, snails and shellfish that feed on aquatic plants) to better distribute and forage around the second auxiliary filler. In addition, these aquatic animals can reduce organic substances such as nitrogen and phosphorus in the water body through adsorption, absorption and species competition mechanisms, control the growth of algae plants, thereby further improving the water purification effect, promoting the flow of energy and matter in the ecosystem, increasing biodiversity, and having a landscape beautification effect at the same time.

[0083] As Figure 5 and Figure 6As shown, further, the water treatment system 1 further includes an aerobic ecological substrate 30. The aerobic ecological substrate 30 is disposed in the water body within the sewage treatment tank 3 and is located between the ecological purification device 20 and the water treatment device 10. The aerobic ecological substrate 30 is used for aerobic biochemical treatment of the water body (such as nitrification treatment). Specifically, before the water body flows into the water treatment device 10 after being treated by the ecological purification device 20, the water body is first subjected to aerobic biochemical treatment (such as nitrification treatment) by the aerobic ecological substrate 30 to remove nitrogen, phosphorus, and organic pollutants in the water body, thereby further reducing the subsequent water treatment load of the water treatment device 10 and improving the effect of water quality purification.

[0084] In one embodiment, the aerobic ecological substrate 30 includes a floating frame and a third auxiliary filler. The floating frame can be, but is not limited to, a PVC floating frame. The floating frame can float on the water surface. The third auxiliary filler is disposed on the floating frame and extends into the water body. The third auxiliary filler is used for the attachment and growth of aerobic microorganisms, and the aerobic microorganisms are used for aerobic biochemical treatment of the water body. Specifically, the aerobic microorganisms attached to the third auxiliary filler carry out their own metabolic activities in an aerobic environment to remove nitrogen, phosphorus, and organic pollutants in the water body; the floating frame can provide a fixed-point support for the third auxiliary filler.

[0085] It should be noted that the user can selectively return the sludge stored in the sludge selection tank 300 of the water treatment device 10 to the water body area where the aerobic ecological substrate 30 is located through a sludge reflux device (sludge reflux pipe and / or sludge reflux pump) to participate in the aerobic biochemical treatment of the water body as a reaction substrate of the aerobic ecological substrate 30.

[0086] As Figure 5 and Figure 6 shown, the water treatment system 1 further includes an aeration device 40. The aeration device 40 is used to inject oxygen into the water body area where the aerobic ecological substrate 30 is located to create an aerobic environment required for the operation of the aerobic ecological substrate 30. Specifically, the strong aeration effect of the aeration device 40 is used to inject oxygen in the air into the water body, and at the same time, the unnecessary gases and volatile substances in the water body are discharged into the air, enabling the aerobic microorganisms in the water body to carry out aerobic respiration with maximum efficiency. Thus, while using the aerobic reaction of the aerobic microorganisms to further decompose the eutrophic substances in the water body, the water body is highly oxygenated, strengthening the oxygen protection of the water body, further reducing the subsequent water treatment load of the water treatment device 10, and improving the effect of water quality purification.

[0087] Optionally, the aeration device 40 includes an aerator 41 and an aeration spraying and discharging assembly 42.

The aeration spraying and discharging assembly 42 can include multiple groups, and the multiple groups of aeration spraying and discharging assemblies 42 are arranged at intervals in the water area where the aerobic ecological base 30 is located.

[0088] Specifically, the aerator 41 can be, but is not limited to, a micro-nano aerator. The characteristics of the micro-nano aerator are as follows:

[0089] 1. High filtration accuracy: Since it is made of micron-level ultra-fine filter materials, its filtration accuracy reaches 0.01μm, which is much higher than the filtration accuracies of conventional ordinary filter materials such as 0.45μm, 0.125μm, and 0.225mmol / L, thus effectively improving the water quality of the effluent.

[0090] 2. Strong corrosion resistance: Since the materials used are made of non-metallic inorganic materials or organic polymer materials, it has the characteristics of being resistant to chemical substances such as acids, alkalis, and salts.

[0091] 3. Long service life: Since the materials used are made of non-metallic inorganic materials or organic polymer materials, it has a relatively long service life; generally, it can ensure a service life of more than 15 years under normal use conditions.

Convenient and flexible installation: The micro-nano aerator can be designed into various shapes, sizes, and structural forms according to user requirements; and it is easy to disassemble, assemble, replace the filter material, clean, and maintain, which is convenient for on-site construction operations and mobile transportation.

[0093] 5. Wide application range: It is applicable to the primary treatment system at the inlet of urban sewage treatment plants and the pretreatment and advanced treatment systems of industrial wastewater treatment as a biological membrane carrier for the adsorption and interception of microorganisms to achieve the purpose of purifying sewage.

[0094] As Figure 5 and Figure 6 shown, further, the water treatment system 1 further includes an auxiliary sedimentation area 50.

The auxiliary sedimentation area 50 is used for sedimentation treatment of the water body, that is, before the water body flows into the water treatment device 10, the water body is pre-treated by gravity natural sedimentation to pre-separate the suspended matter that is easy to precipitate to the bottom of the water body, thereby further reducing the subsequent water treatment load of the water treatment device 10 and improving the effect of water quality purification.

[0095] Furthermore, the water treatment system 1 further includes a fountain machine 60. The fountain machine 60 is disposed in the water body within the sewage treatment tank 3 and is located between the aerobic ecological base 30 and the water treatment device 10. Optionally, the fountain machine 60 can be disposed in the auxiliary sedimentation area 50. On the one hand, the fountain machine 60 can oxygenate the water body and form a certain landscape effect. On the other hand, the fountain machine 60 can perform simple air flotation treatment on the water body, so that the suspended matter that is easy to float on the water surface in the water body floats and is removed.

[0096] As Figure 5 and Figure 6 shown, further, an inlet port 4 is provided on the shore of the water purification area 2 close to the sewage treatment tank 3.
