To solve the problem of light reactivation: open the channel to realize underground water outflow, to avoid or reduce the visibility of treated water before entering the pipeline. At the same time, use a dark container containing a sample of test water, Customized Microwave drying of nuts It shall be sent for inspection in time to avoid factors such as storage conditions or test time affecting the test results. Improve the light transmittance: adjust the front-end treatment process to reduce the SS mass concentration of water in the UV disinfection device, Microwave drying of nuts Price The ultraviolet disinfection I was adjusted to ozone decolorization, which reduced the chromaticity of the influent water to ensure that SS was controlled below 10 mg/L; The front-end technology has been adjusted to strictly control the consumption of PAM and other chemicals, and a defoaming device has been installed at the water inlet of the external disinfection device to reduce the foam content in the water body and increase the light transmittance of the water body.

Activated carbon adsorption and catalytic combustion equipment is a common volatile organic waste gas treatment equipment. It is energy-saving, environmental protection, no secondary pollution, and high purification efficiency. It is a very good equipment for VOC waste gas treatment. Generally, the main components of activated carbon adsorption catalytic combustion equipment are as follows: Pretreatment equipment: since honeycomb activated carbon adsorption requires specific conditions such as temperature, humidity and cleanliness, it is necessary to treat the organic waste gas with different characteristics before entering the activated carbon adsorption. The organic waste gas containing more dust particles needs to be filtered. The waste gas with a temperature greater than 45 ℃ needs to be cooled, and the waste gas containing a large number of water mist particles needs to be separated and filtered. Activated carbon adsorption bed: it can absorb organic waste gas by taking advantage of the porous physical characteristics of activated carbon. The design of the adsorption bed follows the law of two-phase adsorption curve. Only by combining the amount of activated carbon and calculating the cross section wind speed and retention time of activated carbon adsorption can the adsorption efficiency meet the design requirements and meet the emission standards. The box is in negative pressure state during equipment operation, and it is required to be air tight. The desorption temperature of the box is between 70-100 ℃ during the desorption process, and the heat preservation is generally 50mm considering the energy saving and safety factors. Ensure that the temperature of the outer wall of the box is not higher than the normal temperature by 15 ℃. Main exhaust fan: as the main power of the equipment, the exhaust fan guides the air to move according to the specified process. The fan can be selected accurately only when it is stable and reliable, and the resistance calculation of the system is accurate. The operation of the fan will produce noise, and the high-power fan needs to be equipped with a sound insulation room. Attention shall be paid to the design that the wind speed at the air outlet shall not be too high. Catalytic combustion equipment: after the system has operated for a period of time, the activated carbon needs to be regenerated after adsorption saturation to restore the adsorption activity of the activated carbon. The organic waste gas is concentrated in the activated carbon. After the organic matter is separated from the activated carbon layer at low temperature, it is decomposed into water and carbon dioxide at about 300 ℃ through the action of catalyst. At the same time, the energy is released. The energy is replaced by the heat exchange device to maintain the energy of spontaneous combustion of the equipment. For a single activated carbon adsorption bed, the desorption time is 2-2.5 hours. The set time of activated carbon adsorption box is automatically switched to desorption regularly. The service life of the ceramic honeycomb noble metal catalyst loaded inside is 8000 hours. The whole desorption system adopts multi-point temperature control to ensure the stability of desorption effect. The selection of organic waste gas catalyst is the core of this equipment. Valve switching system: valves include adsorption system valve, desorption system valve, cooling and emergency discharge valve. The three types of valves are required to be timely and accordingly to ensure that the air leakage rate is less than 2%. The conventional galvanized sheet air valve in the market has air leakage due to unreliable sealing, so it is necessary to select the high temperature resistant air valve with silicone gasket. The temperature is reliable when opening and closing the valve. Due to the temperature of the gas through which the valve passes, it is very easy for conventional plastic electric actuators to age and deform, resulting in ineffective execution. Generally, long rod actuators are used.

The technology of microwave ultraviolet water treatment equipment is to use double layer ultrafiltration membrane for microwave ultraviolet water treatment equipment, or combine ultrafiltration membrane and reverse osmosis filtration membrane for application. Microwave drying of nuts Price When the manufacturer of microwave ultraviolet water treatment equipment applies external pressure on the concentrated solution side, the penetration speed will decrease. When the pressure increases to a certain value, the penetration process will stop and the so-called penetration balance will be reached. The external pressure under the balance condition is called the penetration pressure. When the pressure on the concentrated solution side continues to increase, that is, when the applied pressure is greater than the penetration pressure, The solvent of purified water equipment will reverse its original soaking direction and enter the dilute solution side from the concentrated solution side through the semi permeable membrane, Customized Microwave drying of nuts This phenomenon is called reverse osmosis. For a long time, it will not only affect the effluent quality of the equipment, but also lead to the fouling of the reverse osmosis membrane of the main components of the equipment, resulting in the small output of the pure water equipment, the substandard effluent quality, or the equipment can not be used. In order to ensure the continuous and safe operation of pure water equipment, the maintenance of pure water equipment is very important.

With the extension of the use time of the clean microwave ultraviolet water treatment equipment, it is a normal phenomenon that the water production decreases. The decrease of water production in winter is due to the decrease of water temperature and permeability, and the change of reverse osmosis membrane density. These two reasons will reduce the water production of microwave and ultraviolet water treatment equipment. Strengthen pretreatment device, Customized Microwave drying of nuts Increasing the cleaning time, replacing the filter element frequently, backwashing the reverse osmosis membrane in time, and extending the interval are all ways to promote the normal operation of the microwave ultraviolet water treatment equipment. Microwave drying of nuts Price If the water pipe or microwave ultraviolet water treatment equipment is frozen, the valve shall be closed in time, wrapped with towel, and slowly watered with warm water. Do not directly use fire for barbecue, nor use boiling water for heating, so as to prevent microwave and ultraviolet water treatment equipment and pipelines from cracking, or use a hair dryer to dry them. At the same time, gently tap hard objects on the water pipe until the pipe freezes and thaws, and the tap water flows out smoothly. If the fully automatic frequency conversion water supply equipment has been frozen, it can only be wrapped with a hot towel and sprinkled with warm water until the pipe freezes and thaws, so that the water can flow out smoothly.
