Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, specifically a dye wastewater degradation treatment system. Background Technology

[0002] Dyes are organic compounds that can impart bright and lasting colors to other substances. They generally possess their own color and can color other substances in either a molecular or dispersed state. Dyes are typically classified into natural dyes and synthetic dyes. Natural dyes are mainly derived from plants, animals, and minerals, while synthetic dyes are artificially synthesized. Dyes have a wide range of applications, not only in the printing and dyeing of various textile fibers but also in industries such as plastics, rubber, inks, leather, and papermaking. Common types of dyes include reactive dyes, sulfur dyes, disperse dyes, and acid dyes. The use of dyes generates a large amount of dye wastewater, which is characterized by large discharge volumes, high color intensity, poor biodegradability, difficulty in degradation, and high toxicity. It has become one of the most difficult industrial wastewaters to treat. Traditional wastewater treatment methods, such as physical treatment, chemical treatment, and adsorption-coagulation, cannot completely remove pollutants from wastewater and suffer from drawbacks such as high cost, large usage, low efficiency, and secondary pollution. Therefore, we propose a dye wastewater degradation treatment system. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a dye wastewater degradation treatment system to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a dye wastewater degradation treatment system, the degradation treatment system comprising: a pretreatment tank, a degradation treatment tank, a detection device and a discharge pipe, wherein the pretreatment tank is connected to the degradation treatment tank, the detection device is located on one side of the degradation treatment tank, and the discharge pipe is interconnected with the interior of the degradation treatment tank.

[0005] The degradation process is as follows:

[0006] S1. Pour the dye wastewater to be treated into the pretreatment tank for pretreatment, and use a screen to filter out large particulate impurities in the wastewater.

[0007] S2. Pour the neutralizing agent into the pretreatment tank and continuously stir the wastewater to ensure that the neutralizing agent is completely dissolved in the wastewater, and wait for sedimentation.

[0008] S3. Pour the pretreated wastewater from the upper layer into the degradation treatment tank and perform centralized cleaning treatment on the sediment in the pretreatment tank.

[0009] S4. Pour cultured fungi and algae into the degradation treatment tank. The fungi and algae degrade the substances in the wastewater. An aeration device is installed. Insert the air pipe into the tank to aerate the degradation treatment tank.

[0010] S5. The detection device is equipped with a prediction model. The prediction model is used to predict the time of water degradation. When the predicted time is reached, the detection device will detect the water quality in the degradation treatment tank. After the water quality meets the discharge standard, the fungi and algae will be filtered out through the filter screen.

[0011] S6. Discharge the filtered wastewater through the discharge pipe in a unified manner.

[0012] Prior to this, in step S1, the screen of the pretreatment tank is located at the top of the tank, completely covering the pretreatment tank. The screen can be freely disassembled and installed. The screen is made of metal wire mesh. The dye wastewater flows into the pretreatment tank through the drain pipe.

[0013] Preferably, the neutralizing agent in step S2 includes one of calcium hydroxide, hydrochloric acid, and lime. The neutralizing agent is used to adjust the pH value of the wastewater. The neutralizing agent is added to the pretreatment tank by scooping it out with a tool spoon and then added to the wastewater. The stirring time is 30 minutes, and stirring is performed 5 minutes after the neutralizing agent is added. The sedimentation time is 1 day.

[0014] Prior to step S3, the pre-treated wastewater from the upper layer is pumped out by a water pump and transported to the degradation treatment tank through pipelines. After the wastewater is completely pumped out, the treatment personnel use a cleaning shovel to collect the sediment and impurities at the bottom of the tank and remove the impurities from the bottom of the tank.

[0015] Preferred, in step S4, the fungus is a white-rot fungus, which is filamentous. It degrades the organic matter in the dye wastewater by producing extracellular enzymes during metabolism. The algae absorb nitrogen and phosphorus from the wastewater to grow and reduce the concentration of substances, thereby improving the wastewater.

[0016] Preferred, the aeration device in step S4 includes an air pump, an air pipe, and an aeration stone. The air pump is used to provide an air source, the air pipe is used to transmit the air source to the aeration stone, and the aeration stone releases oxygen into the water in the form of bubbles. During the wastewater degradation process, the wastewater is continuously aerated for 8 hours.

[0017] Prior to this, in step S5, the prediction model is constructed using a neural network. By inputting the types of algae, the characteristics of the wastewater, and the types of fungi, the model is predicted to achieve the removal rate of pollutants in the wastewater. The dataset is then fed into the model, and the model is continuously optimized.

[0018] Prior to this, neural networks are constructed by the interaction of nodes. A neural network consists of three layers: an input layer, a hidden layer, and an output layer. The input layer is used to input features, the hidden layer is used to learn the relationships between features, and the output layer is used to output the prediction results.

[0019] Prior to this, the detection device in step S5 detects both harmful substances and water quality. The detection device detects water using infrared and electrolytic analysis methods. In the infrared detection step, the instrument is calibrated using infrared standards, a water sample is extracted from the pool, placed in the detection device, infrared light is emitted, the spectrometer is started, an appropriate wavenumber range and scanning speed are selected, the infrared spectrum is recorded, and the recorded infrared spectrum is processed to obtain water quality data.

[0020] Electrolytic analysis involves applying an external voltage to induce oxidation-reduction reactions of ions in a sample at electrodes. During the analysis, the content of harmful substances in the water is recorded and observed. This data is then combined with data from infrared spectroscopy to determine whether the water meets discharge standards.

[0021] Preferred, the emission method in step S6 is direct emission.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] This invention treats dye wastewater using a biodegradation method and incorporates a predictive model to estimate the approximate time required for wastewater treatment. Within the predicted timeframe, a detection device monitors the water to determine if it meets discharge standards before proceeding with the discharge treatment. This approach removes pollutants from the wastewater, reduces costs and usage, and offers better application prospects. Attached Figure Description

[0024] Figure 1 This is a flowchart illustrating the degradation process of this invention. Detailed Implementation

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] This invention provides a technical solution: a dye wastewater degradation treatment system, the degradation treatment system comprising: a pretreatment tank, a degradation treatment tank, a detection device and an discharge pipe, the pretreatment tank being connected to the degradation treatment tank, the detection device being located on one side of the degradation treatment tank, and the discharge pipe being interconnected with the interior of the degradation treatment tank;

[0027] The degradation process is as follows:

[0028] S1. Pour the dye wastewater to be treated into the pretreatment tank for pretreatment, and use a screen to filter out large particulate impurities in the wastewater.

[0029] S2. Pour the neutralizing agent into the pretreatment tank and continuously stir the wastewater to ensure that the neutralizing agent is completely dissolved in the wastewater, and wait for sedimentation.

[0030] S3. Pour the pretreated wastewater from the upper layer into the degradation treatment tank and perform centralized cleaning treatment on the sediment in the pretreatment tank.

[0031] S4. Pour cultured fungi and algae into the degradation treatment tank. The fungi and algae degrade the substances in the wastewater. An aeration device is installed. Insert the air pipe into the tank to aerate the degradation treatment tank.

[0032] S5. The detection device is equipped with a prediction model. The prediction model is used to predict the time of water degradation. When the predicted time is reached, the detection device will detect the water quality in the degradation treatment tank. After the water quality meets the discharge standard, the fungi and algae will be filtered out through the filter screen.

[0033] S6. Discharge the filtered wastewater through the discharge pipe in a unified manner.

[0034] Furthermore, in step S1, the screen of the pretreatment tank is located at the top of the tank, completely covering the pretreatment tank. The screen can be freely disassembled and installed. The screen is made of metal wire mesh. The dye wastewater flows into the pretreatment tank through the drain pipe.

[0035] Furthermore, in step S2, the neutralizing agent includes one of calcium hydroxide, hydrochloric acid, and lime. The neutralizing agent is used to adjust the pH value of the wastewater. The neutralizing agent is poured into the pretreatment tank by scooping it out with a tool spoon and adding it to the wastewater. The stirring time is 30 minutes, and stirring is performed 5 minutes after the neutralizing agent is added. The sedimentation time is 1 day.

[0036] Neutralizing agents are mainly used to remove excess acid or alkali in wastewater so that the pH value of the water meets the requirements. They are mainly divided into two categories: acidic neutralizing agents and alkaline neutralizing agents.

[0037] Acid neutralizers are characterized by a pH value of less than 7, which means they are acidic. They are mainly used for water quality adjustment. Before use, they need to be dissolved in water and added in a certain amount according to the required pH value.

[0038] Alkaline neutralizers are characterized by a pH value greater than 7, meaning they are alkaline. They are also used for water quality adjustment. Similarly, they need to be dissolved in water before use, and then a certain amount is added to the target pH value according to the desired pH value.

[0039] Furthermore, in step S3, the pre-treated wastewater from the upper layer is pumped out by a water pump and transported to the degradation treatment tank through pipelines. After the wastewater is completely pumped out, the treatment personnel use a cleaning shovel to collect the sediment and impurities at the bottom of the tank and remove the impurities from the bottom of the tank.

[0040] Furthermore, in step S4, the fungus is a white-rot fungus, which is filamentous. It degrades the organic matter in the dye wastewater by producing extracellular enzymes during metabolism. The algae absorb nitrogen and phosphorus from the wastewater to grow and reduce the concentration of substances, thereby improving the wastewater.

[0041] Algae can also produce oxygen through photosynthesis, which helps improve the aquatic environment. White-rot fungi are particularly outstanding in the treatment of dye wastewater. White-rot fungi are filamentous, and the extracellular enzymes produced in their secondary metabolic stage have a strong ability to degrade organic matter in dye wastewater. In addition, white-rot fungi have a wide range of adaptability, especially good degradation effect on organic matter such as polycyclic aromatic hydrocarbons, and are suitable for treating highly toxic synthetic dye wastewater.

[0042] Furthermore, in step S4, the aeration device includes an air pump, an air pipe, and an aeration stone. The air pump is used to provide an air source, the air pipe is used to transmit the air source to the aeration stone, and the aeration stone releases oxygen into the water in the form of bubbles. During the wastewater degradation process, the wastewater is continuously aerated for 8 hours.

[0043] Aeration devices also improve water circulation. As a large number of bubbles rise, they drive the water flow and stir up organic matter and suspended solids in the water, promoting water convection circulation. This circulation helps to remove pollutants and introduce new oxygen into the water, thereby improving water quality.

[0044] Furthermore, in step S5, the prediction model is constructed using a neural network. By inputting the types of algae, the characteristics of the wastewater, and the types of fungi, the model predicts the removal rate of pollutants in the wastewater. The dataset is then fed into the model, and the model is continuously optimized.

[0045] Furthermore, neural networks are constructed through the interaction of nodes. A neural network consists of three layers: an input layer, a hidden layer, and an output layer. The input layer is used to input features, the hidden layer is used to learn the relationships between features, and the output layer is used to output the prediction results.

[0046] Furthermore, in step S5, the detection device detects both harmful substances and water quality. The detection device uses infrared and electrolytic analysis methods to detect water. In the infrared detection step, the instrument is calibrated using infrared standards, a water sample is extracted from the pool, placed in the detection device, infrared light is emitted, the spectrometer is started, an appropriate wavenumber range and scanning speed are selected, the infrared spectrum is recorded, and the recorded infrared spectrum is processed to obtain water quality data.

[0047] Electrolytic analysis involves applying an external voltage to induce oxidation-reduction reactions of ions in a sample at electrodes. During the analysis, the content of harmful substances in the water is recorded and observed. This data is then combined with data from infrared spectroscopy to determine whether the water meets discharge standards.

[0048] Furthermore, the emission method in step S6 is direct emission.

[0053] S3. Pour the pretreated wastewater from the upper layer into the degradation treatment tank and perform centralized cleaning treatment on the sediment in the pretreatment tank.

[0054] S4. Pour cultured fungi and algae into the degradation treatment tank. The fungi and algae degrade the substances in the wastewater. An aeration device is installed. Insert the air pipe into the tank to aerate the degradation treatment tank.

[0055] S5. The detection device is equipped with a prediction model. The prediction model is used to predict the time of water degradation. When the predicted time is reached, the detection device will detect the water quality in the degradation treatment tank. After the water quality meets the discharge standard, the fungi and algae will be filtered out through the filter screen.

[0056] S6. Discharge the filtered wastewater through the discharge pipe in a unified manner.

[0057] Comparative Example 1

[0058] The dye wastewater degradation treatment process is as follows:

[0059] S1. Larger particles are removed by a filter screen, and suspended solids in the wastewater are settled by gravity sedimentation or by adding a precipitant.

[0060] S2. By adding chemical agents, the organic matter and pigments in the dye wastewater are degraded and transformed, and the organic matter is reduced into non-toxic or low-toxic substances by reducing agents.

[0061] In Example 1, dye wastewater was treated using a biodegradation method. A predictive model was set up to predict the approximate time it would take to complete the treatment. Within the predicted time, the water body was monitored by a detection device to check whether it met the discharge standards and was then discharged. This method effectively removed pollutants from the wastewater and reduced costs and usage. In contrast, Comparative Example 1 used a combination of physical and chemical treatment methods, which could not completely remove pollutants from the wastewater and was also costly and required large amounts of wastewater, making it very inconvenient.
