Description

Technical Field

[0001] The invention relates to the technical field of water treatment, and in particular to an industrial wastewater treatment device. Background Art

[0002] Industrial wastewater generated in the industrial production process contains a large amount of harmful substances. If untreated industrial wastewater is directly discharged into the environment, it will cause serious pollution and damage to water bodies, soil and ecosystems. Summary of the invention

[0003] The main purpose of the present invention is to provide an industrial wastewater treatment device.

[0004] To achieve the above object, the technical solution adopted by the present invention is:

[0005] An industrial wastewater treatment device comprises a mechanical filtration zone, a biological decomposition zone connected to the mechanical filtration zone, a sedimentation zone connected to the biological decomposition zone, an ozonation zone connected to the sedimentation zone and a filtration zone connected to the ozonation zone; the filtration zone comprises a graded filtration device.

[0006] Furthermore, the graded filtering device comprises a water inlet 1 , which is communicated with a first filter layer 2 , a second filter layer 3 is arranged outside the first filter layer 2 , and a third filter layer 4 is arranged outside the second filter layer 3 .

[0007] Furthermore, the grading filtration device is a cylindrical structure, and the grading filtration device also includes a chassis 8.

[0008] The first filter layer 2, the second filter layer 3 and the third filter layer 4 are detachable structures and are connected to the bottom plate 8 by buckles.

[0009] Furthermore, the first filter layer 2 has a first connecting hole 21 on its wall, the second filter layer 3 has a second connecting hole 22 on its wall, and the third filter layer 4 has a third connecting hole 23 on its wall.

[0010] Furthermore, the first filter layer 2 is filled with a first filter material; the first filter layer 2 and the second filter layer 3 are filled with a second filter material; and the second filter layer 3 and the third filter layer 4 are filled with a third filter material.

[0011] Furthermore, the size of the first filter material is larger than that of the second filter material, and the size of the second filter material is larger than that of the third filter material.

[0012] Furthermore, the first filter material, the second filter material and the third filter material may be one or more of activated carbon, quartz sand, ceramic particles, resin beads and zeolite.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The graded filtering device of the present invention realizes the gradual purification of wastewater by setting up three filter layers. Each filter layer is provided with a connecting hole, which ensures that the wastewater can be evenly distributed on the filter layer, avoids the problems of local overload and blockage, and improves the filtering efficiency.

[0015] The detachable design of the filter layer means that when a layer of filter material reaches saturation or needs to be replaced, only that layer needs to be removed without disassembling the entire filter device, which greatly reduces maintenance costs and time. The number and type of filter layers can also be flexibly adjusted according to actual wastewater treatment needs to adapt to different wastewater treatment scenarios.

[0024] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0025] See also Figure 1-5As shown, an industrial wastewater treatment device includes a mechanical filtration zone, which can preliminarily remove large impurities such as suspended matter and particulate matter in the industrial wastewater; a biological decomposition zone connected to the mechanical filtration zone, which decomposes organic pollutants in the industrial wastewater by microorganisms; a sedimentation zone connected to the biological decomposition zone, which precipitates the sediment produced in the biological decomposition zone to achieve solid-liquid separation, and the liquid part enters the ozonation zone connected to the sedimentation zone, and the ozonation zone uses the strong oxidizing property of ozone to remove difficult-to-degrade organic matter and some inorganic pollutants in the wastewater; finally, the wastewater enters the filtration zone connected to the ozonation zone; when there is too much industrial wastewater, the industrial wastewater can be temporarily stored in a reservoir, and the reservoir is connected to the mechanical filtration zone through a pipeline, and the filtration zone includes a graded filtration device.

[0026] Furthermore, the graded filtering device comprises a water inlet 1 , which is communicated with a first filter layer 2 , a second filter layer 3 is arranged outside the first filter layer 2 , and a third filter layer 4 is arranged outside the second filter layer 3 .

[0027] Furthermore, the first filter layer 2, the second filter layer 3 and the third filter layer 4 are detachable structures.

[0028] Furthermore, the first filter layer 2 has a first connecting hole 21 on its wall, the second filter layer 3 has a second connecting hole 22 on its wall, and the third filter layer 4 has a third connecting hole 23 on its wall.

[0029] Furthermore, the first filter layer 2 is filled with a first filter material; the first filter layer 2 and the second filter layer 3 are filled with a second filter material; and the second filter layer 3 and the third filter layer 4 are filled with a third filter material.

[0030] Furthermore, the size of the first filter material is larger than that of the second filter material, and the size of the second filter material is larger than that of the third filter material.

[0031] Furthermore, the first filter material, the second filter material and the third filter material may be activated carbon, quartz sand or other materials capable of removing impurities and pollutants in wastewater.

[0032] Wastewater enters the first filter layer 2 of the graded filtration device from the water inlet 1. The larger filter material can preliminarily remove larger particles and adsorb some pollutants. The treated water enters between the first filter layer 2 and the second filter layer 3. The medium-sized filter material will further remove medium-sized particles and pollutants. Finally, the treated water enters between the second filter layer 3 and the third filter layer 4 to remove tiny particles and residual pollutants. The detachable structure can also be adjusted according to specific needs, which increases the flexibility of use.

[0033] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment.
