With the continuous scale development of urban industrial production, factories in the production process continue to discharge a large amount of sewage to the outside world, which has caused very bad pollution to the environment, so there are those simple methods of sewage treatment? Today   Sanli Fengxiang   will introduce to you the three most common treatment methods!   According to its principle of action can be divided into the physical method, biological method and chemical method of these three.   Physical Method The main use of physical action to separate the non-soluble substances in the sewage, in the treatment process does not change the chemical properties. Commonly used are gravity separation, centrifugal separation, reverse osmosis, air floatation, etc.. The physical method treatment structures are simpler and more economical, and are used in cases where the capacity of the village water body is large, the self-purification capacity is strong, and the degree of sewage tr

In recent years, the reduction of the ozone layer will increase the ultraviolet rays reaching the earth's surface, thereby increasing the incidence of skin cancer. Therefore, the requirements for the development of UV protection agents are becoming stronger. TiO2 particles not only have small particle size (transparent), high activity, strong ability to absorb ultraviolet rays, but also have good decolorizing power, hiding power, non-toxic, odorless, and good dispersibility. These characteristics determine TiO2 has an important position in the field of cosmetics and is widely used in cosmetics, especially sunscreens. TiO2 can be stably and evenly dispersed in cosmetics, using its absorption of ultraviolet rays, so as to achieve the effect of preventing sun aging. Titanium Dioxide   Titanium dioxide, also known as titanium oxide or titania, is the naturally occuring oxide of titanium,chemical formula TiO2. Due to its small particle size and high activity, titanium dioxide particles
