Beschreibung
Zusammenfassung:	An alkali recovering process for the black liquor of straw pulp includes diffusion dialysis of digested black liquor to obtain diluted alkali solution, dividing electric dialysis chamber into anode and cathode chambers by monocational diaphragm, circulating black liquor in anode chamber, circulating diluted alkali solution in cationde chamber, electric dialysis at ordinary temp and pressure by applying 8-10 v DC voltage and 1 A current, acid separating, biochemical treating, and electrically catalytic oxidization. Its advantages are high recovery yield of alkali, and low energy consumption.
