Ultrafiltration anti-microbial activated carbon bar and preparation method thereof

Abstract

The invention discloses an ultrafiltration anti-microbial activated carbon bar and a preparation method thereof.The ultrafiltration anti-microbial activated carbon bar is prepared from, by weight, 15-35 parts of 80-150-mesh anti-microbial particle powdered carbon, 15-40 parts of 150-250-mesh anti-microbial particle powdered carbon, 5-15 parts of 250-350-mesh anti-microbial particle powdered carbon and 10-30 parts of binder.The ultrafiltration anti-microbial activated carbon bar has the filtration effect of a water purification membrane and the adsorption effect of an activated carbon bar, and particularly can kill microorganisms, and it is ensured that the carbon bar will not produce microorganisms or generate nitrite, and the total number of effluent bacterial colonies reaches the standard.In addition, through application of the technology, a water purification product can change a traditional membrane-plus-carbon multilevel filter element water purification structure, the same water purification effect can be achieved just through a single filter element structure of the ultrafiltration anti-microbial activated carbon bar, many defects such as a complex structure, water leakage and troublesome filter element replacement of the water purification product can be effectively overcome, and market development and industrial progress of the water purification product can be greatly boosted.

Description

technical field [0001] The invention relates to the field of water purification, in particular to an ultrafiltration antibacterial activated carbon rod and a preparation method thereof. Background technique [0002] Due to the serious environmental pollution and the improvement of living standards, people pay more and more attention to the health and safety of drinking water. The water purification industry in my country has developed rapidly and has a potential market size of hundreds of billions. It was conceived and born. [0003] Generally speaking, micro-pollutants in tap water include: microorganisms, organic matter, solid inclusions (such as rust, sediment), colloids, etc. The basic filtration principle adopted by various water purification products is: membrane plus carbon, the membrane mainly includes ceramic membrane, organic ultrafiltration membrane, reverse osmosis membrane, etc., and the carbon is mainly granular carbon filter element or activated carbon rod fil...

AI Technical Summary

Problems solved by technology

[0004] 1) Since water purification products adopt the basic water purification principle of membrane plus carbon, the structure of water purification products is complex, and many pipeline connections are used. Water purification products often leak water, which brings bad experience and unnecessary waste to consumers. At the same time, water purification products often require a lot of after-sales service work, such as the maintenance and replacement of multiple filter elements, which greatly limits the marketing of water purification products, and also causes a lot of inconvenience to consumers.

[0005] 2) Secondary pollution of microorganisms in water purification products, the total number of effluent colonies exceeding the standard, nitrous acid exceeding the standard, etc.; the reason is that activated carbon has excellent adsorption effect, absorbing a large amount of organic matter and providing sufficient nutrients for the reproduction of microorganisms. In a suitable environment, it will multiply in large numbers, and the metabolism of microorganisms will produce carcinogen nitrite, and at the same time cause the total number of colonies in the effluent to exceed the standard
