[Abstract]:

Recently, the group's "key technology integration research and application project of free radical oxidation and biological oxidation advanced treatment of wastewater" has reached the leading level in China and obtained the "science and technology achievement certificate of Hebei Province".

The evaluation team is composed of experts from Hebei Academy of Environmental Sciences, Hebei Academy of Sciences, North China Institute of pharmaceutical and environmental protection, Hebei University of science and technology and other industries. The leaders of science and Technology Award and achievement transformation Office of Hebei Provincial Department of science and Technology participated in the whole meeting for guidance. The board of directors, vice president, chief environmental protection scientist Chen Ping, director, vice president and Party committee of TIANS Group wrote Zhang XinQiao, Chen XiaoFei, director of Chenping laboratory, and Liu HaiBing, engineer of environmental protection division, accompanied the defense.

Chen XiaoFei, director of Chenping Laboratory of TIANS Group, first made a detailed report on the research content, technological innovation, achievements, transformation and application of the project. After the inquiry and discussion of the expert group, it is agreed that the technical route of the project is reasonable, the experimental demonstration is sufficient and objective, the industrialization application effect is good, and it has significant economic, social and environmental benefits, reaching the domestic leading level.

Based on the free radical oxidation technology, the project developed the photoelectric combined catalytic oxidation technology and the ozone hydrogen peroxide coordinated catalytic oxidation technology. Through the coupling with the biological oxidation technology, two kinds of advanced treatment combined processes of photoelectric combined catalytic oxidation + new biological aerated filter and nano microbubble ozone hydrogen peroxide coordinated catalytic oxidation + NEW biological aerated filter were formed, which solved the free problem The problems of low efficiency of radical oxidation, high energy consumption and poor coupling of unit technology form the key technology and equipment of free radical oxidation and biological oxidation for advanced wastewater treatment. By giving full play to the advantages of each unit treatment process, the removal rate of COD is more than 80%, the removal rate of ammonia nitrogen and total phosphorus is increased by more than 20%, and the cost is saved by more than 10%.

The achievement of this achievement marks a new breakthrough in the field of advanced wastewater treatment of TIANS Group, Form the leading technology and equipment in China, accelerate the technological progress and upgrading of environmental protection industryIn the future, the group will actively carry out the research on the comprehensive treatment technology of industrial three wastes in combination with the rigid demand of the new round of environmental protection treatment technology, constantly accelerate the transformation and industrialization of scientific research achievements in the field of environmental treatment, and become a comprehensive solution service provider covering multiple industries for the advanced treatment and resource utilization of industrial three wastes.
