Water is one of the substances that human beings can survive. However, with the development of economic construction, the problem of water pollution has become increasingly prominent. At the same time, water treatment equipment has come into play. In addition to daily industrial wastewater and domestic sewage treatment, water treatment equipment is also a guarantee for water quality in disaster areas. The lake in the landscape lake of the university campus, after a five-minute deep treatment of “bathingâ€, became a clear drinking water that can be directly consumed. The guests rushed to try to “slowâ€. On June 4th, students and guests who participated in the World Environment Day Science Popularization Program witnessed this “magic†water treatment process in Wuhan Business School. At the scene, a set of water treatment equipment called “Powder Activated Carbon Purification Drinking Water Process†is in operation. One end of the equipment is a pump, which draws lake water from the lake, and the other end is a faucet, which is flowing out of the clear drinking water. . A number of guests and classmates took the bottle to pick up the water and praised it. "There is no smell of chlorine in the tap water." "It's very refreshing, it is the feeling of pure water." "Our equipment used in this equipment can directly treat five types of lake water into direct drinking water that can be directly consumed. It takes about 2 yuan to process 1 ton of water." Liu Lujian, dean of Junji Water Treatment Research Institute, Wuhan Institute of Business and Technology Introduction, the core technology of this process is “recycled powder activated carbon sewage treatment technologyâ€. This technology is the first in China. The main principle is to reduce the sewage treatment cost and improve the sewage treatment efficiency by re-activation of used activated carbon. Effect. 　 It is understood that this technology will be promising in earthquake relief. “When the water plant is catastrophic, as long as the equipment is transported to the site, the local water source can be used to supply water to the resettlement sites of the victims.†Liu Lujian said that they are also studying and applying this technology to the rapid purification of water pollution. Events, pollution control of lakes, etc.
