The application belongs to the technical field of new materials, and particularly relates to a preparation method and application of a MIL-101(Fe) cage-encapsulated MnO2 nanoparticle composite material. The application uses the metal-organic framework (MOF) material MIL-101(Fe) with two kinds of mesoporous cages and one kind of microporous cage as a carrier, encapsulates the MnO2 metal oxide nanoparticles in the three cage structures of the structure, and thus prepares a new composite material MnO2-in-MIL-101(Fe) in which the MnO2 nanoparticles completely enter the MOF cage instead of being aggregated on the surface to block the MOF channels. The MnO2-in-MIL-101(Fe) of the application is a catalytic material with high efficient catalytic capacity, and the highly dispersed nanoscale MnO2 can effectively exert the ozone degradation performance. Meanwhile, the preparation method of the application is simple in operation, good in repeatability, mild in conditions and friendly to the environment.

An ozone catalytic oxidation reaction tower can realize gas-liquid intermittent contact and separation, and comprises a tower tank, a gas distribution disc, a gas-liquid separation layer, a liquid level meter, a spray header, an ozone generator and an ozone destructor, the centralized water treatment direct drinking water system containing the catalytic ozonation reaction tower further comprises a raw water inlet pipeline, a raw water tank, a booster pump, a sand filter, a carbon filter, an ion exchanger, a micron filter, a nano filter, a water supply pump set, a water return pipeline and a precision filter. According to the catalytic ozonation reaction tower disclosed by the utility model, water to be treated falls down layer by layer in a raining form through the spray heads and the densely-distributed drainage grooves in the gas-liquid separation layer, and ozone is dispersed in the tower tank through the densely-distributed exhaust holes and is gradually lifted, so that the ozone and the water to be treated are in large-range contact and long-time full contact; the pollutant degradation efficiency of ozone is greatly improved; according to the direct drinking water system applying the reaction tower, as the water treatment efficiency is improved, 'treatment and pumping 'are realized at the peak period of water consumption.

The present disclosure describes material surface treatment systems and methods that employ a byproduct treatment system to receive a byproduct generated by application of a plasma, the byproduct treatment system configured to degrade the byproduct and exhaust the degraded byproduct from the material surface treatment.

This invention discloses a device and method for the efficient degradation of ozone through a three-phase synergistic process. The device includes an atomization system, a spray tower with a gas absorption pump, and an auxiliary system. The spray tower contains an organic-modified activated carbon layer. Ozone gas is forcibly drawn in by the absorption pump, enriched by the adsorption layer, and then comes into countercurrent contact with organic droplets, undergoing synergistic degradation under UV excitation and constant temperature conditions. Using a 0.5 g / L cysteine-ascorbic acid-glutathione mixed solution (pH=9.4), a UV intensity of 1.34 W / m², a temperature of 39.5℃, an activated carbon addition height of 2.54 cm, and a gas flow rate of 21.1 L / h, the ozone degradation rate reaches 90.957%. This invention is particularly suitable for ozone purification in microenvironments.

The present application belongs to the technical field of electric ozone, and particularly relates to a biochar material, a preparation method and application thereof, a gas penetration type electrode and a gas-lift liquid flow type electric ozone device.

The gas penetration type electrode prepared by using the biochar material as a catalyst is applied to the gas-lift liquid flow type electric ozone device, and in actual application, can improve the gas dispersion system, strengthen the mass transfer of ozone and oxygen to the electrode, increase the utilization rate of ozone and oxygen, realize the effect of simultaneously improving degradation efficiency and reducing energy consumption, and promote the large-scale application of electric ozone in degrading pollutants.

This invention discloses a plasma ventilation and purification device and method, relating to the field of energy conservation and environmental protection. When airflow occurs, the plasma ventilation and purification device uses a wind pressure sensor to collect wind pressure data and sends it to a centralized control module. The centralized control module outputs stored voltage, current, and frequency operating parameters to power the plasma generator. The generated plasma density is indirectly detected by an ultraviolet sensor and an ozone sensor. After the detection data is sent to the centralized control module, it automatically adjusts the output voltage, current, and frequency values ​​to ensure that the plasma density is consistently highest and the ozone content is lowest under different environments. The cathode plate can collect particles and can be extracted for cleaning, eliminating the need for intermediate and high-precision filters, ultraviolet generators, and other facilities, thus reducing the size and weight of the device. The ozone degrader converts ozone into oxygen, ensuring that the ozone content does not exceed the standard and improving air purification efficiency. This achieves energy-saving and environmentally friendly effects such as no consumables required, human-machine coexistence, sterilization, pollution degradation, and automatic operation.
