Fist on Fighting
Tsinghua University research team led by Professor Liu Huijuan developed a new electrochemical chemistryThe system is expected to completely change the metal recycling in industrial wastewater. The research was published in the "Engineering" magazine.In their research, The team proposed a new method of integrating transient electric field (TE) and spin (SF) to improve quality transmission and promote interface ion transmission at the same time.
The research team discussed the effects of different operating conditions (including operating mode, transient frequency, and flow) on metal recovery.They found that the best conditions for recycling copper in the Te & Amp; SF mode are achieved through low -electricity levels, high levels of 0 and 4V, 50%duty cycle, 1kHz frequency, and 400L/h flow.The dynamic coefficients of TE & amp; sf are 3.5−4.3 times and 1.37−1.97 times a single TE and SF electricity stealth, respectively.
This innovative method overcomes the limitations of interface ion transmission in the traditional electrical deposition method. The team successfully improved the body phase and interface ion transmission by coupling the transient electric field and turbulence, thereby enhancing the reaction dynamics.The synergy of transient electric field and spinning can not only realize the rapid recycling of metal, but also achieve sediments with uniform components and uniform appearances. In addition, the system shows extensive applicability in the recycling of hydrogen analysis potential than the metal of hydrogen analysis and water reduction. This ability can realize the high value recovery of precious metals and heavy metals, making it a valuable asset for the industry to deal with metal waste.
Professor Liu Huijuan and his team conducted a new insight for the efficient recycling metal from industrial wastewater. Their discovery has opened up the possibility of environmental friendly and efficient metal recycling technology, which helps reduce pollution and protect valuable resources.

Macro market observation
—— Industry development process: The industry is in the rapid progress stage
Since the founding of the Peoples Republic of China, my countrys industrial wastewater treatment industry has gone through four development stages.In the 1960s, my countrys industrial wastewater treatment industry was lacking in quarterly, and industrial wastewater treatment technology was backward. After years of development, my countrys industrial wastewater treatment industry has developed rapidly. With the support of national policies, industrial wastewater treatment facilities have continued to improve, industrial wastewater treatment The degree of marketization of the industry has continued to increase.
—— The overall situation of industrial water use
2015-- In 2021, my countrys industrial water consumption and the proportion of total water consumption have decreased year by year.On the one hand, the state has implemented the implementation of industrial water regulation policies, and on the other hand, the awareness of water -saving awareness of industrial enterprises in my country has continued to increase.In June 2022, the Ministry of Water Conservancy released data. The 2021 industrial water was 104.96 billion cubic meters, accounting for 17.7%of the total water.In general, my countrys industrial water management has achieved remarkable results.
—— The discharge of the main pollutants of industrial source wastewater
According to the "National Ecological Environment Statistics" issued by the Ministry of Ecology and Environment of China, from 2016-2021, the main pollutants in industrial source wastewater in my country include COD (chemical oxygen demand), ammonia nitrogen, and total nitrogen. The overall emissions are declining. It shows that my country has strengthened industrial wastewater treatment capabilities, and the quality of industrial wastewater treatment has also improved.Specifically, COD has always been the category of pollutants with the largest discharge volume of wastewater in industrial sources. According to the "2021 China Ecological Environment Statistics Annual Report" released by the Ministry of Ecology and Environment, it is 423,000 tons in 2021.Under acidic conditions, the amount of oxygen required for the oxygen of the organic matter in one liter of sewage can be roughly indicated that the amount of organic matter in the sewage can be roughly indicated.Followed by total nitrogen, the emission volume in 2021 is 100,000 tons.
——The processing capacity of industrial wastewater treatment plant
my country More than 10 years ago, industrial wastewater has been started, and investment has been continuously increased. Most industrial enterprises have also built wastewater treatment facilities. At the same time, the state implements the pollution license system, which requires direct or indirect enterprise institutions to discharge wastewater to water bodies. , Get pollution permits.However, due to the low cost of illegal illegal, coupled with insufficient supervision and poor law enforcement, the phenomenon of stealing industrial enterprises and causing serious environmental pollution still occur frequently.The incident of wastewater pollution has aroused continuous concern of public opinion and will further become catalysts that promote the government to introduce more strict governance policies.
According to the data disclosed in the "Urban and Rural Construction Statistical Yearbook" published by the Ministry of Housing and Urban-Rural Development, from 2012 to 2021, the processing capacity of the urban and county sewage treatment plants in my country increased year by year, and the city was increased year by year, and the cities were increased year by year, and the cities were increased year by year, and the cities were increased year by year, and the city was increasing year by year, and the cities were increased year by year, and the city was increasing, and the city The sewage treatment plant has a strong processing capacity.According to the latest data released by the Ministry of Housing and Construction in October 2022, in 2021, the processing capacity of my countrys urban sewage treatment plant is 20.767 million cubic meters per day, and the processing capacity of the sewage treatment plant of the county is 39.79 million cubic meters per day, totaling 24.746 million Cube meter/day.
