Description

Technical Field

[0001] The utility model relates to the technical field of industrial wastewater treatment, and specifically relates to a purification device for phenol-containing industrial wastewater with a nano-laccase filter layer. Background Technique

[0002] Industrial wastewater includes production wastewater, production sewage and cooling water, which refers to the wastewater and waste liquid generated during the industrial production process.

[0003] When adding industrial wastewater into the reaction tank, the industrial wastewater is not filtered at this time, so there may be certain impurities or precipitates in the industrial wastewater. When the reagent filter element reacts with the wastewater for purification, these impurities or precipitates will also participate in the purification process, which not only leads to a large consumption of reaction reagents and frequent replacement of the filter element, but also causes blockage of the drain pipe and the reagent filter element by impurities or precipitates when discharging the purified industrial wastewater subsequently.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a purification device for phenol-containing industrial wastewater with a nano-laccase filter layer is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a purification device for phenol-containing industrial wastewater with a nano-laccase filter layer to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A purification device for phenol-containing industrial wastewater with a nano-laccase filter layer, including a purification tank and a filtering component. A filtering chamber is arranged on the right side inside the purification tank, and a connecting elbow is vertically inserted in the middle of the filtering chamber. The filtering component is longitudinally and equidistantly clamped on the inner wall of the filtering chamber. The filtering component includes a stainless steel frame, a filter screen layer, through holes and a particle filling layer. Filter screen layers are arranged at the upper and lower ends of the stainless steel frame, and through holes that are hermetically matched with the connecting elbow are opened in the middle of the stainless steel frame. A particle filling layer is filled between the upper and lower filter screen layers, and the particle filling layer is nano-cured laccase particles.

[0007] Further, an overflow port is opened on the side wall of the filtering chamber, and the height where the overflow port is located is greater than the water inlet height of the connecting elbow.

[0008] Further, adjacent stainless steel frames are parallel to each other and parallel to the bottom surface of the filtering chamber, and the stainless steel frame is hermetically connected to the inner wall of the filtering chamber.

[0009] Further, a screening chamber is arranged on the left side inside the purification tank, and the side of the screening chamber is connected to the bottom end of the filtering chamber through a connecting elbow.

[0010] Furthermore, one side of the top of the screening bin is connected with a water inlet pipe, and a slot is provided on the other side of the top of the screening bin.

[0011] Furthermore, a screening component is arranged inside the slot. The screening component includes a grille and a limiting strip. The grille is composed of a stainless steel outer frame and a metal mesh woven together. The bottom of the grille is clamped and matched with the limiting strip, and the limiting strip is fixed to the bottom surface of the screening bin.

[0012] Furthermore, the screening component further includes a pull-out plate and a guiding conical surface. The grille is in clearance fit with the perforation in the middle of the pull-out plate, and guiding conical surfaces are arranged on both sides of the pull-out plate.

[0013] Furthermore, the screening component further includes a mounting plate and a brush. Mounting plates are symmetrically arranged on both sides of the top of the grille, and brushes are arranged on the inner sides of the opposite surfaces of the mounting plates.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. When the utility model is in use, the filter component of the present application is composed of a particle filling layer composed of upper and lower filter mesh layers filled with nano-cured laccase particles. It can directly catalyze and oxidize and decompose various phenolic dyes, substituted phenols, chlorophenols, aromatic amines, etc. by using oxygen in the air. Since laccase has broad substrate specificity and good stability, laccase has a very great application prospect in treating phenolic industrial wastewater.

[0016] 2. When the utility model is in use, after the industrial wastewater is introduced into the purification tank through the water inlet pipe, it first passes through the screening bin to filter impurities or precipitates in the industrial wastewater. The above-mentioned impurities or precipitates are intercepted and adsorbed on the grille. Just draw the grille out upwards from the slot, and the brush on the inner side of the mounting plate can dredge the impurities blocking the mesh holes on the grille. The fallen impurities fall to both sides of the pull-out plate along the guiding conical surface, and then the pull-out plate is drawn out from the slot to carry out rapid cleaning, greatly reducing the downtime required for cleaning the grille, so that the filtered wastewater is introduced into the filtration bin through the connecting elbow, reducing the rapid consumption of the particle filling layer caused by the reaction between impurities or precipitates and nano-cured laccase particles, and thereby prolonging the service life of the filter component.

The filtration components 9 are longitudinally and equally spaced and clamped on the inner wall of the filtration bin 6. The filtration component 9 includes a stainless steel frame 901, a filter mesh layer 902, a through hole 903, and a particle filling layer 904. Adjacent stainless steel frames 901 are parallel to each other and parallel to the bottom surface of the filtration bin 6, and the stainless steel frame 901 is hermetically connected to the inner wall of the filtration bin 6. Filter mesh layers 902 are arranged at the upper and lower ends of the stainless steel frame 901, and a through hole 903 that is hermetically matched with the connecting elbow 7 is opened in the middle of the stainless steel frame 901. A particle filling layer 904 is filled between the upper and lower filter mesh layers 902, and the particle filling layer 904 is nano-cured laccase particles. After the filtered wastewater enters the filtration bin 6 through the connecting elbow 7, the rapid consumption of the particle filling layer 904 caused by the reaction of impurities or precipitates with the nano-cured laccase particles is reduced, thereby prolonging the service life of the filtration component 9. The filtration component 9 of the present application is composed of a particle filling layer 904 filled with nano-cured laccase particles in the upper and lower filter mesh layers 902, and can directly catalytically oxidize and decompose various phenolic dyes, substituted phenols, chlorophenols, aromatic amines, etc. by using oxygen in the air. Since laccase has broad substrate specificity and good stability, laccase has very great application prospects in the treatment of phenol-containing industrial wastewater;

[0023] As Figures 1 to 2As shown in the figure, a screening bin 2 is arranged on the left side inside the purification tank 1, and the side of the screening bin 2 is communicated with the bottom end of the filtering bin 6 through a connecting elbow 7. One side of the top of the screening bin 2 is communicated with a water inlet pipe 3, and a slot 4 is opened on the other side of the top of the screening bin 2. A screening component 5 is arranged inside the slot 4. The screening component 5 includes a grille 501 and a limiting strip 502.

The bottom of the grille 501 is clamped and matched with the limiting strip 502, and the limiting strip 502 is fixed to the bottom surface of the screening bin 2. The screening component 5 further includes a pull-out plate 503 and a guiding conical surface 504.

Just pull the grille 501 out upwards from the slot 4, and the brush 506 on the inner side of the mounting plate 505 can dredge the impurities blocking the mesh holes on the grille 501.

[0024] Working principle: When using the phenol-containing industrial wastewater purification device with a nano-laccase filter layer, after the industrial wastewater is introduced into the purification tank 1 through the water inlet pipe 3, the impurities or sediments in the industrial wastewater are first filtered by the screening bin 2. The above-mentioned impurities or sediments are intercepted and adsorbed on the grille 501. Just pull the grille 501 out upwards from the slot 4, and the brush 506 on the inner side of the mounting plate 505 can dredge the impurities blocking the mesh holes on the grille 501. The fallen impurities fall to both sides of the pull-out plate 503 through the guiding conical surface 504, and then the pull-out plate 503 is pulled out from the slot 4 to carry out quick cleaning, greatly reducing the downtime required for cleaning the grille 501. After the filtered wastewater enters the filtering bin 6 through the connecting elbow 7, it reduces the rapid consumption of the particle filling layer 904 caused by the reaction between the impurities or sediments and the nano-cured laccase particles, thereby prolonging the service life of the filtering component 9.
