[0024] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] Plasma activated water technology can produce a large amount of active substances in a short time, and the operating conditions are mild. It shows good potential in the degradation of microplastics and can accelerate the degradation process. At the same time, it is relatively friendly to the environment and can avoid the risk of secondary pollution. Therefore, this application applies plasma activated water to the degradation of microplastics, such as Figure 1 As shown, a microplastic degradation treatment system is provided, including: a plasma active water preparation device 1, a microplastic degradation device in water 2, a monitoring and control device 3 and a power supply device 4.

[0027] The plasma-activated water preparation device 1 includes a plasma generator and a water collection device; the plasma generator is used to generate plasma; the plasma is plasma-activated in the water collection device to obtain plasma-activated water; the water collection device is connected to the microplastic degradation device 2 in the water body; the microplastic degradation device 2 in the water body is used to hold water containing microplastics; the monitoring and control device 3 is respectively connected to the plasma-activated water preparation device 1 and the microplastic degradation device 2 in the water body; the monitoring and control device 3 is used to adjust the output power of the plasma generator; the power supply device 4 is respectively connected to the plasma generator, the microplastic degradation device 2 in the water body and the monitoring and control device 3.

[0028] The biggest advantage of the microplastic degradation treatment system provided by the above embodiment is efficient degradation: plasma active water is more efficient than existing microplastic degradation methods, with a short treatment cycle and simple operation, and no additional chemical reagents are required. Active water contains a large amount of active substances, which have very strong oxidizing ability and can quickly attack the microplastic molecular chains, causing them to break and degrade. Moreover, it can process a variety of plastics at room temperature without obvious selective restrictions on different types of plastics.

[0029] In an exemplary embodiment, the plasma generator includes one or more electrode units; the power supply device 4 and the monitoring and control device 3 are both connected to the electrode unit; the electrode unit is used to generate plasma under the excitation of the power supply device 4; and the monitoring and control device 3 is used to adjust the voltage of the electrode unit.

[0030] The plasma active water preparation device 1 includes a power supply, an electrode unit, a reaction vessel, etc. The power supply provides energy, and the electrode generates an electric field and maintains discharge. The power supply is connected to the power supply device 4, specifically, after the solar energy passes through the solar panel + energy conversion device, the solar energy is converted into alternating current, and the alternating current is used for the power supply of the plasma generator. The power supply transfers energy to the plasma through the electrode, specifically, converting the low-voltage alternating current into high-voltage electricity, and then preparing and generating plasma, thereby realizing the generation and control of plasma. The high-energy particles and active substances in the plasma are plasma-activated with the water contained in the reaction vessel to obtain plasma active water. The water collection device in this application is the reaction vessel. Then enter the microplastic degradation device 2 in the water body for the next step of treatment. There is an electrode unit in the plasma generating device. By adjusting the electrode voltage, the electron energy and density of the plasma can be changed, and plasma reactions of different intensities can be generated, thereby preparing plasma active water containing active substances of different concentrations. Plasma reactions of different intensities can prepare plasma active water of different concentrations, and the adjustment method is to regulate the voltage, which can be continuously adjustable. According to the size of the microplastic particle size fed back by the sensor in the microplastic degradation device 2 in the subsequent water body, the control system in the monitoring and control device 3 adjusts the electrode voltage. The monitoring device in the monitoring and control device 3 is mainly a sensor, which understands the state of the microplastics in the water body through the sensor signal, and then feeds back to adjust the voltage of the plasma to achieve the regulation of the concentration of the active substance.

[0031] In another exemplary embodiment of the present application, the microplastic degradation device 2 in water includes a degradation water tank and a microplastic monitoring sensor; the microplastic monitoring sensor is installed in the degradation water tank; the microplastic monitoring sensor is respectively connected to the power supply device 4 and the monitoring and control device 3; the microplastic monitoring sensor is used to monitor the size and / or shape of microplastics in the water body; the monitoring and control device 3 is used to adjust the output power of the plasma generator according to the monitoring information of the microplastic monitoring sensor.

[0032] In practical applications, the microplastic monitoring sensor is a spectrophotometer.

[0033] In another exemplary embodiment of the present application, the microplastic degradation device 2 in water further includes a stirrer; the stirrer is disposed in the water of the degradation water tank; the stirrer is used to stir the water in the degradation water tank. In practical applications, the stirrer is a turbine stirrer.

[0034] The microplastic degradation device places the water containing microplastics to be treated in the degradation water tank, and the plasma-activated water enters the degradation water tank from the preparation device through the connecting pipe. A simple stirrer is added to the degradation water tank, and the plasma-activated water is stirred all the time during the process of microplastic degradation to ensure that the microplastics in the water can be evenly distributed and fully contact the plasma-activated water, thereby enhancing the contact between the microplastics and the plasma and improving the degradation efficiency of the microplastics. The stirrer can stir all the time, or the stirring rate can be adjusted according to the monitoring data of the microplastic monitoring sensor.

[0035] In practical applications, the water collecting device is connected to the degradation water tank through a pipeline.

[0036] In another exemplary embodiment of the present application, the power supply device 4 is a solar power supply device. In practical applications, the power supply device 4 also includes a water collection and storage device 5; the water collection and storage device 5 is arranged at the solar panel of the solar power supply device; the water collection and storage device 5 is connected to the water collection device; the water collection and storage device 5 is used to store the dew accumulated by the solar panel and transmit the dew to the water collection device. The solar power supply device is used to provide the electric energy required by the system, and at the same time, a water collection and storage device 5 is added to store the dew accumulated by the solar panel to supplement the water resources required for the preparation of active water. The biggest advantage of the power supply device 4 using a solar power supply device is energy saving and environmental protection: the use of a solar power supply device reduces dependence on external electricity, realizes a green and sustainable treatment method, reduces system operating costs, and reduces the consumption of traditional energy. Through the graded discharge mode combining strong, medium and weak electricity, the discharge intensity can be flexibly adjusted according to the different characteristics and processing progress of microplastics to avoid excessive energy consumption. Plasma active water degradation of microplastics can effectively avoid secondary pollution and will not cause other damage to the environment.

[0037] The control system in the monitoring and control device 3 is connected to the sensor, which is installed on the degradation device. The sensor monitors the size, morphology and other characteristics of microplastics in the water, and feeds back to the control device, flexibly adjusts the electrode voltage to correspond to the discharge modes of strong electricity, medium electricity and weak electricity of different intensities, and adjusts the output power of the plasma generator in time to ensure the accuracy and efficiency of the discharge mode. The strong electricity mode is used to treat microplastics that are difficult to degrade and have large particles in the water body, the medium electricity mode is used for conventional degradation tasks, and the weak electricity mode is used for later detail processing and low energy consumption processing. Among them, the size, morphology and other characteristics of microplastics are measured by spectrophotometry, mainly monitored by a spectrophotometer, and the sensor provides a feedback signal to the plasma generator, and then the plasma generator controls the discharge by adjusting its own input voltage. The discharge mode in this application and the degradation task corresponding to the discharge mode can be set by yourself, and then adjusted. According to the characteristics of the product, for example, the degree of degradation of microplastics can be set by yourself. The monitoring and control device 3 is used to realize automatic intelligent control: through the feedback adjustment mechanism of the sensor and the monitoring and control device 3, it is possible to monitor the water quality changes in real time and automatically select the most suitable discharge mode, so that the system runs more intelligently and accurately, and reduces human intervention.

[0038] In another exemplary embodiment of the present application, the plasma generator also includes a concentration sensor; the concentration sensor is connected to the monitoring and control device 3; the monitoring and control device 3 is used to adjust the output power of the plasma generator according to the concentration sensor and the microplastic monitoring sensor.

[0039] The present application provides an efficient and energy-saving treatment system for directly using plasma active water to degrade microplastics in water. The system will change the commonly used fixed discharge mode and intensity, combine three different discharge modes of strong electricity, medium electricity, and weak electricity for comprehensive treatment, connect the control system with the sensor, and automatically select and switch different discharge modes by real-time monitoring of the characteristics and degradation progress of microplastics in water, solving the problems of energy waste and uneven treatment effect in traditional plasma water treatment systems. And using a solar charging device as an energy source, it effectively improves the efficiency of microplastic degradation and reduces energy consumption. At the same time, the water storage function of the solar charging device can also provide a certain amount of water resources for the preparation of plasma active water.
