Regarding the provision on page 102 of the Guidance Catalog for Industrial Structure Adjustment (2019 edition), under the category of processes and technologies to be phased out, the statement that \"wet flue gas desulfurization processes without accompanying sulfur recovery units\" fall into this category refers, in my opinion, to conventional alkali washing methods, the sodium hydrosulfide production method, and the MDEA physical absorption method. Such processes must be accompanied by sulfur recovery techniques such as complexed iron sulfur recovery or Claus sulfur recovery; they are considered processes and technologies to be phased out in both environmental impact assessments and for new enterprises. Or directly adopt the LYSY iron-sulfur recovery system. It seems that in the future, industrial enterprises will no longer be able to discharge wastewater without recovering sulfur.
