摘　　要：Brief review of the evolutive course of preparation and refining of mother liquor in Hou’s soda-manufacturing Process and the historical root of inferior quality of the product from Hou’s Process to that of Ammonium Soda Process. By determination in production, the technical causes of carrying of "escaping crystal" in flooding liquid from the salting out crystallizer and necessity of replacing the existing mother liquor Ⅱ vat by mother liquor Ⅱ settling tank. Theoretical and engineering basis of refining of mother liquor in Hou’s Process is emphasized. Main results from field test of purification and filtration at low temperature of mother liquor Ⅱ prepared from three kinds of salt as raw material are introduced. Principle opinions of application on production are put forward.Brief review of the evolutive course of preparation and refining of mother liquor in Hou's soda-manufacturing Process and the historical root of inferior quality of the product from Hou's Process to that of Ammonium Soda Process.
