This article will objectively analyze the development trend in the field of industrial water treatment technology. The analysis factors include annual literature output, country/regional output, cooperative publications, major institutions, research topic distribution, etc., revealing the countries and institutions in the field of industrial water treatment technology. R&D strength and research hotspots to help people in this field quickly understand and grasp the research overview and development context.
Judging from the country's publication situation, China, India, the United States, Iran, Spain, Turkey, Brazil, South Korea, the United Kingdom and Germany accounted for more than 60% of the total number of papers published.
Judging from thesis research topics, adsorption, dye removal, heavy metals, photocatalysis, reaction kinetics, advanced oxidation technology, methylene blue, activated carbon, degradation, thermodynamics, etc. are the most popular research topics in the field of industrial wastewater treatment.
From the perspective of global patent layout, China has now become the main country in the field of industrial wastewater treatment technology, accounting for 51% of the global share.
Judging from the year trend of paper output, research papers in the field of global industrial wastewater treatment technology first originated in 1945. Subsequently, the number of paper output began to show an upward trend from 1990. The growth rate has increased since 2005, and has increased since 2013. The range has reached a record high, with the number of papers in 2019 reaching 6,768.
Judging from the country's publication situation, China, India, the United States, Iran, Spain, Turkey, Brazil, South Korea, the United Kingdom and Germany accounted for more than 60% of the total number of papers published. Among them, China’s paper output is far ahead of other countries, with India and the United States ranking second and third respectively. In terms of national cooperation in publishing documents, China has the largest number of cooperative documents with foreign countries and a wide range of cooperation areas. Among them, it cooperates most closely with the United States; secondly, it also has relatively in-depth cooperation with the United Kingdom, Germany and Brazil.
In terms of research topics, adsorption, dye removal, heavy metals, photocatalysis, reaction kinetics, advanced oxidation processes, methylene blue, activated carbon, degradation, thermodynamics, etc. are the most popular research topics in the field of industrial wastewater treatment.
Judging from the year trend of patent output, the global development and evolution of industrial wastewater treatment technology can be divided into three periods. The first is before 1995, when the annual number of patent applications slowly increased. The second period is from 1995 to 2015. The number of patent applications has increased significantly. The third stage is after 2015, when the number of annual patent applications surges, reaching the highest level in history. The earliest year of patent applications in China began in 1985, which is 20 years later than the earliest year of global patent applications in this field. However, its growth trend is similar to that of the world, and its contribution to the world is growing day by day. The number of patent applications in 2018 reached a peak of 6,288. , accounting for 91.62% of the global share.
Judging from the status of national documents issued, patents related to industrial wastewater treatment technology are widely distributed around the world, involving more than 60 countries/regions. China is the main country in the field of industrial wastewater treatment technology, accounting for 51% of the global share, far ahead of Japan (13% share) and the United States (7% share). Europe ranked fourth with a share of 4%, and South Korea and Germany tied for fifth with a share of 3%. Canada and Germany are the two countries most active in cooperative patent application activities in the field of industrial wastewater treatment technology. They have both cooperated with the United States to apply for multiple patents. Secondly, China and Japan and Japan and the United States also cooperate more frequently. In addition to Japan, China, the United States, South Korea and other countries have also applied for cooperation.
The degree of industrialization in my country's industrial wastewater treatment technology research field needs to be improved, and the industrial wastewater treatment technology market still needs to be further expanded. We should work together with world-renowned multinational groups. The purpose of cooperation is to join forces and jointly consolidate the core position of all parties. Our company provides a variety of water treatment solutions to meet all the needs of customers, growing together with global customers and protecting the environment!
