The second sludge discharge pipe 181 includes multiple pipes, and the multiple second sludge discharge pipes 181 are respectively arranged in one-to-one correspondence with the multiple sludge selection boxes 300.

[0074] like Figure 4 As shown, further, the water treatment device 10 also includes a dosing unit 400, which is disposed on the top of the reaction chamber 200. The dosing unit 400 is used to add flocculants to the reaction chamber 200. Optionally, the dosing unit 400 includes a medicine storage barrel, a dosing pipe and a dosing pump. One end of the dosing pipe is connected to the medicine storage barrel, and the other end of the dosing pipe is connected to the medicine storage barrel. The dosing pump is disposed on the dosing pipe, and the dosing pipe is used to pressurize the flocculant in the medicine storage barrel and inject it into the reaction chamber 200 with the help of the dosing pump.

[0075] like Figure 4 As shown, the water treatment device 10 further includes a control cabinet 500, which is disposed on the top of the reaction chamber 200, and the control cabinet 500 is used to control the operation of the water treatment device 10. Further, the water treatment device 10 further includes an operating platform 600 for users to walk on to perform operations of the water treatment device 10, and the operating platform 600 is disposed on the top of the reaction chamber 200. Specifically, the control cabinet 500 and the dosing unit 400 are both disposed adjacent to the operating platform 600.

[0076] Furthermore, the above-mentioned water treatment device 10 also includes a solar power supply device 700, which is arranged on the top of the reaction chamber 200. The solar power supply device 700 is used to convert solar energy into electrical energy to power various electrical equipment of the water treatment device 10, so that the various electrical equipment of the water treatment device 10 can be used normally without being connected to the mains, and is not restricted by the site, is energy-saving and environmentally friendly, and has low investment and operating costs.

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

[0078] In one embodiment, the water treatment system 1 can be arranged in a water purification area 2, which can be arranged near a sewage source (e.g., a breeding pond), and the water purification area 2 is provided with a sewage treatment tank 3, which can be arranged in the middle of the water purification area 2, and the water to be treated can be stored in the sewage treatment tank 3. The water treatment device 10 can be arranged 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 arranged in the water in the sewage treatment tank 3. When the water treatment device 10 is needed to purify the water, the user can use a water delivery device (e.g., a water delivery pipe and / or a water pump) or use gravity to transport the water in the sewage treatment tank 3 to the reaction chamber 200 of the water treatment device 10, so that the water treatment device 10 performs deep treatment on the water. After the water treatment device 10 is finished, the effluent after deep treatment by the water treatment device 10 is discharged to a designated location by means of a water delivery device or gravity.

[0079] like Figure 5 As shown, further, the water treatment system 1 also includes an ecological purification device 20, which is arranged 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 water body is pre-treated ecologically and biochemically by the ecological purification device 20 to remove pollutants in the water body, thereby reducing the subsequent water treatment load of the water treatment device 10, and the ecological purification device 20 also has a good ecological landscape effect, which can meet the landscape aesthetic requirements of the environment in which the water purification area 2 is located.

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

[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 matter in the water body, and 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 denitrification and phosphorus removal, such as canna, iris, round coin grass, foxtail algae, water plantain, water lily, etc., which can not only achieve the function of denitrification and phosphorus removal of the water body and ensure the water quality of the effluent, but also improve the environmental landscape of the environment in which the water body is located 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 filler, a fiber filler or a composite filler.

[0082] In one embodiment, the second ecological base 22 includes a floating bed and a second auxiliary filler. The floating bed can be, but is not limited to, a PVC floating bed. The floating bed can float on the surface of the water body. 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 to cultivate algae and aquatic animals (such as fish, snails and shellfish that feed on aquatic plants). The algae can decompose inorganic matter in the water body through its own photosynthesis and release oxygen, thereby achieving the removal of inorganic matter in the water body. The floating bed provides a fixed-point support for the second auxiliary filler, so that aquatic animals (such as fish, snails and shellfish that feed on aquatic plants) can be better distributed around the second auxiliary filler to find food. In addition, the aquatic animals reduce organic substances such as nitrogen and phosphorus in the water body through adsorption, absorption and competition mechanism between species, and control the growth of algae, thereby further improving the effect of water purification, promoting the mobility of energy and materials in the ecosystem, and increasing the diversity of organisms. At the same time, it also has the effect of landscaping.

[0083] like Figure 5 and Figure 6As shown, further, the water treatment system 1 also includes an aerobic ecological base 30, which is arranged in the water body in the sewage treatment tank 3 and is located between the ecological purification device 20 and the water treatment device 10. The aerobic ecological base 30 is used to perform aerobic biochemical treatment (such as nitrification treatment) on the water body. Specifically, before the water body is treated by the ecological purification device 20 and flows into the water treatment device 10, the water body is first aerobic biochemically treated (such as nitrification treatment) by the aerobic ecological base 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 water purification effect.

[0084] In one embodiment, the aerobic ecological base 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 surface of the water body. The third auxiliary filler is arranged 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 to perform aerobic biochemical treatment on the water body. Specifically, the aerobic microorganisms attached to the third auxiliary filler carry out their own metabolic activities in an aerobic environment, thereby removing 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 box 300 of the water treatment device 10 to the water area where the aerobic ecological base 30 is located through the sludge return equipment (sludge return pipe and / or sludge return pump) to participate in the aerobic biochemical treatment of the water body as a reaction substrate of the aerobic ecological base 30.

[0086] like Figure 5 and Figure 6 As shown, the water treatment system 1 also includes an aeration device 40, which is used to inject oxygen into the water area where the aerobic ecological base 30 is located to create an aerobic environment required for the aerobic ecological base 30 to work. 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, unnecessary gases and volatile substances in the water body are expelled into the air, so that aerobic microorganisms in the water body can perform aerobic respiration with maximum efficiency, thereby utilizing the aerobic reaction of the aerobic microorganisms to further decompose the nutrient-rich substances in the water body while highly oxygenating the water body, thereby strengthening the oxygenation protection of the water body, further reducing the subsequent water treatment load of the water treatment device 10, and improving the water purification effect.

[0087] Optionally, the aeration device 40 includes an aerator 41 and an aeration spray assembly 42. The aerator 41 can be arranged at the bank of the water purification area 2 near the sewage treatment tank 3, and the aeration spray assembly 42 is arranged in the water body area where the aerobic ecological base 30 is located, and is connected to the aerator 41 pipeline. The aeration spray assembly 42 is used to spray the oxygen generated by the aerator 41 into the water body area where the aerobic ecological base 30 is located. The aeration spray assembly 42 can include multiple groups, and the multiple groups of aeration spray assemblies 42 are arranged at intervals in the water body area where the aerobic ecological base 30 is located.

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

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

[0090] 2. Strong corrosion resistance: Since the material used is made of non-metallic inorganic materials or organic polymer materials, it is resistant to acid, alkali, salt and other chemical substances;

[0091] 3. Long service life: Since the material used is made of non-metallic inorganic material or organic polymer material, the service life is long; under normal use, it can guarantee a service life of more than 15 years;

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

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

[0094] like Figure 5 and Figure 6 As shown, further, the water treatment system 1 also includes an auxiliary sedimentation area 50, which is arranged in the sewage treatment tank 3 and is located between the aerobic ecological base 30 and the water treatment device 10. The auxiliary sedimentation area 50 can be arranged in the sewage treatment tank 3 in a water area relatively close to the water treatment device 10. The auxiliary sedimentation area 50 is used to perform sedimentation treatment on the water body, that is, before the water body flows into the water treatment device 10, the water body is pre-precipitated by gravity to separate the suspended matter in the water body that is easy to settle to the bottom of the water body in advance, thereby further reducing the subsequent water treatment load of the water treatment device 10 and improving the water purification effect.

[0095] Furthermore, the water treatment system 1 also includes a fountain machine 60, which is arranged in the water body in 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 arranged in the auxiliary sedimentation area 50. The fountain machine 60 can enrich the water body with oxygen and form a certain landscape effect on the one hand, and can perform simple flotation treatment on the water body on the other hand, so that suspended matter that is easy to float on the water surface in the water body can float and be removed.

[0096] like Figure 5 and Figure 6 As shown, further, a water inlet port 4 is provided near the bank of the sewage treatment tank 3 in the water purification area 2, and the water inlet port 4 is connected to the sewage treatment tank 3.

A clean water channel 5 is also provided near the bank of the sewage treatment tank 3 in the water purification area 2, and the clean water channel 5 is arranged around the sewage treatment tank 3. The clean water channel 5 is used to collect the effluent treated by the water treatment system 1. Specifically, the water outlet 112 of the water treatment equipment 100 extends to the clean water channel 5, so that the effluent treated by the water treatment system 1 is discharged into the clean water channel 5. Further, a clean water outlet 6 connected to the clean water channel 5 is also provided near the bank of the sewage treatment tank 3 in the water purification area 2, and the clean water outlet 6 is used to discharge the water in the clean water channel 5.

[0097] Furthermore, the water purification area 2 is provided with an overflow port 7 near the bank of the sewage treatment tank 3, the overflow port 7 is connected to the sewage treatment tank 3, and the overflow port 7 is used to discharge the excess water in the sewage treatment tank 3.
