July 11, 2012, the State Department, through the "energy saving" 12th Five-Year Plan "to ensure that by 2015, ammonia nitrogen, total nitrogen oxide emissions reduced by 10% binding target. Song Yunhua believe that China's chemical industry ammonia wastewater reduction task is arduous, to achieve the ammonia emission reduction targets, also need to have strong technical support. At present, China's traditional ammonia wastewater treatment technology and low efficiency, high energy consumption, high cost, should be adopted to increase the intensity of technology development, the ammonia emission reduction and resource use. 

Song Yunhua said, stripping off ammonia technology-based, China needs to develop the following key technologies: First, high ammonia technology, energy saving technology, resources recycling technology. On the basis of the above techniques, but also technology and device serialization, complete sets and automation. 

It is reported that Beijing University of Chemical Technology has developed complete sets of technology to the four high-concentration ammonia wastewater treatment, including stripping rectification ammonia technology, dual-efficiency energy-saving stripping ammonia technology, energy efficient coupling stripping ammonia and hypergravity stripping off ammonia technology, depending on the the deamination wastewater ammonia content, respectively, using different technologies to achieve the recycling of ammonia nitrogen resources. These techniques have been dozens of chemical plants in Ningxia, petroleum chemical plants, chemical plants, Taiyuan, Shanxi, BASF Nanjing catalyst plant was applied, and achieved good social and economic benefits.
