Abstract:

The HPF desulfurization waste liquid(DWL) treatment technology in China and abroad are summarized and discussed. The discussion on the analysis shows that:HPF desulfurization waste liquid treatment technology can mainly be divided into two categories:salt extraction treatment technology and salt decomposition treatment technology. Based on the introduction of these technologies, their advantages and disadvantages are analyzed individually. Furthermore, a new resource treatment technology of DWL is also introduced. The technical procedure is simple and conditions easy to be controlled. The treated wastewater can meet the requirements of biochemical processing inlet water, obtaining excellent industrial products of ammonium thiocyanate, as well.

Key words: HPF method, wet desulphurization with ammonia, coking desulfurization waste liquid, ammonium thiocyanate
