[Daily Question 20090313] A multiple-choice question about flue gas desulfurization
Thread Content
Dear sea friends: Hello everyone! In February, with everyone's support, the environmental protection zone has significantly improved both the quality and quantity of posts! However, due to my limited ability, during the "Daily Question" activity in the environmental protection zone, the theme of the activity was always multiple-choice questions, with single content and too rigid content, which caused a lot of controversy in the forum! But I firmly believe that if you sow melons, you will reap melons, and if you sow beans, you will reap beans! With the enthusiastic support of all friends, the environmental protection zone will surely flourish! As the saying goes, a three-day break is better than a wedding! The "Daily Question" activity in the Environmental Protection Zone has been launched again after four days! We sincerely hope that everyone can actively participate in the activities and at the same time abide by the "Daily Question" activity plan (revised in 20090312) http://bbs.hcbbs.com/thread-383197-1-1.html Related rules to further improve the quality of postings. In addition, the environmental protection zone carries out the "One Belt One" activity (long-term implementation) http://bbs.hcbbs.com/thread-409617-1-1.html , and everyone is invited to participate at the same time! [Daily Question 20090313] Regarding flue gas desulfurization requirements: Answer choices must provide a basis for your choice.
