味精废水菌体蛋白浆料变气压过滤脱水研究

Studies on the Variable Air-Pressure Filtration Dehydration of Mycelium Protein Slurry in Monosodium Glutamate Waste Water

研究了味精废水菌体蛋白浆料的过滤特性与变气压过滤脱水的主要工艺 .结果表明 :味精废水絮凝分离得到的菌体蛋白浆料为极可压实性物料 ;对絮凝菌体蛋白浆料宜选用型号为 12 0 - 747的涤纶滤布 ;采用 3× 10 4 Pa (90s)→ 7× 10 4 Pa(90s)→ 12× 10 4 Pa(90s)→ 18× 10 4 Pa(30s)

The major technique of the variable air pressure filtration dehydration of mycelium protein slurry in monosodium glutamate waste water was studied. The results showed that: a) the flocculation slurry was very compressible. b) the 120 747 filter cloth type was suitable for the flocculation slurry. c) the efficacy of filtration dehydration was increased by the air pressure adjustment mode 3×10 4 Pa(90 s)→7×10 4 Pa(90 s)→12×10 4 Pa(90 s)→18×10 4 Pa(30 s).
