Microwave ultraviolet water treatment equipment And other engineering technology effectiveness, but less cost effectiveness. The core element that really affects technological breakthrough and promotion and application is cost. If the cost is not considered, there is basically no technical problem in domestic sewage treatment and it can be treated to any level. This is especially true of rural domestic sewage. Relatively speaking, the components of rural sewage treatment are relatively simple, the concentration of pollutants is low, and a large number of mature technologies such as ultraviolet sterilizers have been developed; Different technologies have different demands on collection pipe network, energy and power, materials, etc., and the corresponding cost inputs vary greatly. What the countryside really needs is not the world's engineering technology, but practical technologies such as ultraviolet sterilizers whose cost can be accepted by the government, village collectives, villagers and other relevant subjects. The high cost problem of rural domestic sewage treatment in China is closely related to the current mode selection. Because rural domestic sewage treatment has been neglected for a long time, the government is still accustomed to using urban domestic sewage treatment, hoping to solve the problem through large investment, while ignoring the particularity of rural areas.
microwave Ultraviolet water treatment equipment It has high sterilization efficiency and safe and reliable operation. Ultraviolet disinfection has a high inactivation efficiency for bacteria and viruses, and since no chemical agent is added, it will not cause secondary pollution to the water body and the surrounding environment.
It has a special disinfection effect on cryptosporidium and giardia. The conventional chlorine disinfection process has a very low inactivation effect on cryptosporidium and giardia, and a large number of disinfection by-products will be produced at a high chlorine dosage, while ultraviolet disinfection can achieve a high inactivation effect on cryptosporidium and giardia at a low ultraviolet dose.
It does not produce toxic and harmful by-products and does not increase the TOC content of drinking water. Ultraviolet disinfection does not change the characteristics of organic matter, and because no chemicals are added, it will not produce harmful by-products to human body, and will not increase TOC, BOD and other by-products that damage the biological stability of water in the pipe network.
It can reduce odor and degrade trace organics. Ultraviolet light has a certain ability to degrade a variety of trace organics in water, and can reduce the odor and taste of water.
The ultraviolet disinfection equipment covers a small area, is simple in operation and maintenance, and has low cost. For the disinfection of 50000 tons of sewage with chlorine every day, a 130 meter long and 3 meter wide contact channel needs to be built. UV disinfection only requires an area of 20m long and 3m wide; Ultraviolet disinfection has simple operation and maintenance, low operation cost, up to only 4 cm per ton of water or even lower, and its performance price ratio has great advantages.
