 Water is essential for human beings' life. Our daily life is consuming a lot of water, but also discharged a lot of wastewater. For example, in 2014, only in China, near 14 billion tons of wastewater was discharged. Wastewater contained many pollutants, like organics, nitrogen, phosphorus, bacteria, caused serious water pollution. Over the world, near 4,000 children die every day for pure water quality, and 700 million people are suffering from water shortage problems. For emulating water pollution, many wastewater treatment plants have been constructed, but limited by the traditional process, normally the effluent cannot meet the standard for water reuse, and the huge energy is consumed by aerator, pumps, and so on. So here, we propose a research idea, that is, innovative wastewater management tries to recycle wastewater and recover energy contained in wastewater, tries to maximize use of wastewater resources. So, we can imagine, someday, you lost yourself in an outdoor of exploration, running off water, there is a river in front, but apparently, it's too dirty to drink. If there are such devices, it can devise dirty water into drinkable water that must be very excited. In our lab, Kaminin used its membrane technology. It's the same film with a porous structure during the filtration of wastewater, suspended bacteria, and other impurities can be rejected while water can pass through the membrane, produce the clean water. So, with this advantage, membrane technology can be combined with other treatment processes. For example, we can use a membrane technology combined by a technology together for my innovative technology, namely, membrane bioactor with the stable efferent, with high quality, can be produced. The efferent of membrane bioactor normally is free of bacteria and can be reused for toilet flushing and the landscape irrigation and also can be reused for industrial water supply and even portable water if the deep treatment was further applied. Carbon, as a main pollutant in wastewater, is a potential source of energy. But in traditional wastewater treatment process, the carbon is degraded by adding external energy, not recovering. If we use microorganisms as biocatalysts, recovering the carbon becomes possible. Microorganisms usually have a very small size and a huge surface area and while they exist in land-water atmosphere, they have a very high metabolic ability. By using this powerful microorganism, chemical energy in wastewater can be recovered in different ways. For example, using bioelectro-system can directly produce electricity and if we use the anaerobic digesting, we can produce the methane, heating gas, then we can get the semitinously with water treatment and energy recovering. Recently, one rapidly developing direction that is electricity generation, some special bacteria can act as organics in wastewater and semitinously produce electricity. Produced electricity can be recovered and be utilized in certain in wastewater treatment itself, reduce its energy consumption. So through membrane technology and biotechnology respectively, wastewater can be recovered for recycling water and the source in wastewater and the energy be recovering. For practical application of this technology, we still have many challenges For example, we need to develop more robust membrane and more effective membrane-falling treatment technology for wider application and for bioelectro-system, we also need effort to enhance the power production and reduce the equipment cost. So through break this technique challenge, we hope future new wastewater management model, the wastewater is no longer wasted and should be resource and energy. Thank you for your attention.
