[0002] With the increasing expansion of basic research and applied research in my country, colored and toxic wastewater generated in laboratories has become an environmental problem that needs to be solved urgently. How to solve this type of experimental wastewater problem efficiently and environmentally friendly has become more urgent. Secondly, with the widespread use of natural and synthetic dyes in production and life, how to quickly treat them with low cost and high efficiency has also become a very difficult problem. Printing and dyeing wastewater contains a variety of components that can cause environmental pollution, such as colored dyes, heavy metals, etc. Some dye molecules, such as triphenylmethane dyes, anthraquinone dyes, and azo dyes, are highly stable and toxic, and have three-way effects, posing a huge threat to the natural environment and human health.

[0003] At present, the treatment methods for colored and toxic wastewater mainly include: physical method, chemical method and biological method. Although traditional physical method and chemical method can improve water quality in the short term, they are expensive, difficult to completely decolorize dye wastewater, and will cause secondary pollution. In comparison, biological method has strong adaptability, non-toxicity, renewable, degradable and other green and environmentally friendly advantages.

[0004] Therefore, biological decolorization and purification equipment that can treat dye wastewater more efficiently and conveniently needs to be studied urgently. Utility Model Content

[0005] Based on the shortcomings of the above-mentioned existing technologies, the utility model provides a device for quickly and conveniently achieving wastewater decolorization and purification, so as to more efficiently achieve decolorization and detoxification of dye waste liquid and avoid the secondary pollution problem caused by traditional physical and chemical methods.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A device for decolorizing and purifying wastewater has the following structural features: it includes a reaction chamber that is arranged upright and has an open upper end, in which a stirring and water storage area, a filler area and a water distribution area are arranged in sequence from bottom to top; and the filler area is filled with fillers that have the function of decolorizing and purifying wastewater.

[0008] Furthermore, an inverted funnel-shaped water inlet area is provided at the upper end of the reaction chamber. The upper opening of the water inlet area serves as the water inlet for the reaction chamber; the water inlet area is removably screwed onto the water distribution area. This water inlet structure slows down the speed of water entering the chamber, preventing the packing below from being dispersed by the violent impact of the water flow, while ensuring sufficient contact between the wastewater and the packing.

[0009] Furthermore, a portable screen is provided between the water distribution area and the filling area. The wall thickness of the reaction chamber is defined by the height of the bottom end of the portable screen, with the wall thickness above the portable screen being smaller than the wall thickness below the portable screen. A step is formed at the intersection, and the portable screen rests on the step under its own weight, leaving a gap between the portable screen and the inner wall of the water distribution area.

[0010] Furthermore, a fixed screen is provided between the filler area and the stirring water storage area, and the two areas are separated by the fixed screen.

[0011] Furthermore, a magnetic stirrer is provided in the stirring water storage area. The bottom of the reaction chamber is connected to the magnetic stirrer.

[0012] Furthermore, a water outlet extending outward is provided on the side wall of the stirring water storage area, and the water outlet is connected to the outside of the reaction chamber through a pipeline. A piston is provided at the water outlet for controlling the water outlet rate.

[0013] Furthermore, the filler is immobilized mycelium microspheres, preferably immobilized natural fungal mycelium microspheres, such as one or two of Schizophyllum mycelium, Agaricus foetida mycelium, Ganoderma lucidum mycelium, and the like.

[0014] Compared with the existing technology, the beneficial effects of the present invention are embodied in:

[0015] 1. The device of this utility model has a simple structure and is easy to operate. Through simple control, it can achieve efficient and environmentally friendly biological wastewater treatment. In combination with a filler that has the function of decolorizing and enzymatically degrading dyes, it can simultaneously treat wastewater, degrade dye molecules, remove heavy metals, and improve the decolorization performance of the entire system.

[0016] 2. When treating wastewater, the device of the utility model has low treatment cost and can be reused.

[0017] 3. The packing area of ​​this utility model utilizes immobilized mycelium microspheres as a biological filler medium. In dye wastewater treatment, immobilized mycelium microspheres not only purify the dye wastewater but also increase microbial density, prevent microorganisms from escaping into the wastewater, and improve reuse. The packing produced using immobilization technology ensures the device's recyclability and reduces maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The following is a description of the application of the present invention in achieving simultaneous decolorization and heavy metal removal in dye wastewater treatment, in conjunction with the accompanying drawings. The following embodiments are implemented based on the technical solution of the present invention, and provide detailed implementation methods and specific operating procedures, but the scope of protection of the present invention is not limited to the following embodiments.

[0020] like Figure 1 As shown, the device for decolorizing and purifying wastewater provided by the present invention includes a vertically arranged reaction chamber 1 with an open top, wherein the reaction chamber 1 is provided with a stirring and water storage area 11, a filling area 12, and a water distribution area 13 from bottom to top. The filling area 12 is filled with a filler having the function of purifying wastewater.

[0021] An inverted funnel-shaped water inlet area 2 is provided at the upper end of the reaction chamber 1. The upper end opening of the water inlet area 2 is the water inlet 1a of the reaction chamber 1; the water inlet area 2 is detachably screwed onto the water distribution area 13 through a threaded structure 21. After the wastewater enters the water inlet, it passes through the inverted funnel-shaped water inlet area and is then decolorized and purified in the reaction chamber 1. The provision of a detachable water inlet area facilitates the replacement and cleaning of internal fillers, screens and other structures. At the same time, when the wastewater enters the water inlet 1a, the inverted funnel-shaped water inlet area 2 can slow down the flow rate of the wastewater, allowing the wastewater to slowly enter the reaction chamber 1, ensuring sufficient decolorization and purification and not easily damaging the filler microspheres.

[0022] A portable screen 3 is installed between the water distribution area 13 and the filling area 12. The wall thickness of the reaction chamber 1 is defined by the height of the bottom of the portable screen 3. The thickness of the upper portion of the wall is smaller than that of the lower portion, forming a step at the intersection. The portable screen 3 rests on this step under its own weight, leaving a gap between it and the inner wall of the water distribution area 13. The portable screen 3 can block large-diameter particles of wastewater pollutants.

[0023] A fixed screen 4 is provided between the filler area 12 and the stirring water storage area 11. The fixed screen filters large-diameter particulate pollutants while fixing the filler.

[0024] A magnetic stirrer 5 is provided in the stirring and water storage area 11, and a magnetic stirrer 7 is connected to the bottom of the reaction chamber 1. When in use, the magnetic stirrer is turned on to control the flow of wastewater in the packing area and the water distribution area through stirring, so that the wastewater is fully in contact with the packing and improves the treatment efficiency.

[0025] The side wall of the stirring water storage area 11 is provided with an outwardly extending water outlet 1b, which is connected to the outside of the reaction chamber through a pipe and is used to discharge the decolorized and purified water. A piston 6 is provided at the water outlet 1b to control the water outlet rate.

[0026] The filler is immobilized mycelium microspheres, preferably immobilized natural fungal mycelium microspheres, such as one or two of the mycelium of Schizophyllum, Agaricus foetida, and Ganoderma lucidum. These fungi have excellent decolorization and heavy metal removal properties in wastewater, achieving efficient purification through the dual effects of adsorption and enzymatic decolorization. In practice, the immobilized mycelium microspheres can be obtained according to the method described in patent CN202011016010.6.

[0027] In a specific implementation, the reaction chamber can be made of rigid PVC material, with the area below the portable screen thickened to form a step to secure the portable screen. The reaction chamber can be configured as cylindrical, square, or other shapes as needed. The size of the reaction chamber can be adjusted based on the reaction requirements. In this embodiment, the reaction chamber is cylindrical, the volume of the packing area is set to 1 L, and the wastewater is circulated.

[0028] The method for decolorizing and purifying wastewater using the above device is as follows:

[0029] First, close piston 6 at outlet 1b and turn on magnetic stirrer 7 (at an appropriate speed). Add experimental dye liquor wastewater or printing and dyeing wastewater to the device through water inlet 1a. It enters water distribution area 13 through the inverted funnel-shaped water inlet area 2. Large-diameter particulate wastewater pollutants are blocked by portable screen 3. After initial treatment, the wastewater enters packing area 12, where it comes into contact with the packing for purification. The treatment is carried out at room temperature for 6-8 hours, maintaining low stirring speed. After purification, open piston 6, and the purified wastewater is discharged through outlet 1b.

[0030] After one batch of wastewater is treated and discharged, the next batch of wastewater can be treated immediately. After 3-5 batches of wastewater are treated, the packing can be replaced according to the actual situation to ensure the purification effect, and the replaced packing medium can be regenerated.

[0031] The device of the utility model can effectively remove dye molecules and heavy metal ions in waste water, and has high purification efficiency.

[0032] The above are merely exemplary embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
