とが行われているが、小さな工場では不可能なことから
、みかん缶詰加工を断念した工場もある。In the prior art and during that period, pectin-containing wastewater, typified by wastewater from canned mandarin oranges, had pectin that could not be decomposed by conventional activated sludge treatment, but almost no pectin was removed. For this reason, mandarin orange canning factories have introduced a large 12 m tube to decompose and remove pectin through methane fermentation, but this is not possible in small factories, so some factories have given up on canning mandarin oranges. There is also.
そのためペクチンを低分子化し貞化しうるような好気的

る。Penicillium bacteria cells created in this manner are adhered and immobilized on polyester fibers, and submerged in an Akebono tank. Waste water from canned mandarin oranges is introduced into the tank to reduce the molecular weight of pectin and partially decompose it. Measurement of the molecular weight distribution by gel filtration revealed that this microbial treatment degrades the high molecular weight pectin into trimers and tetramers of galacturonic acid.Next, by treating this treated solution with activated sludge, pectin Most of the wastewater from canned mandarin oranges is decomposed, and other neutral sugars contained in the wastewater from canned mandarin oranges are also decomposed by the activated sludge. Based on more than 0 experimental facts, the wastewater from canned mandarin oranges is treated by a combination of pectin-degrading bacteria and activated sludge bacteria. It has become clear that this is an effective method. Furthermore, when Penicillium yantinerum is attached and immobilized on polyester fibers, the bacterial cell concentration in water is approximately 800 Dpp-1.
0000 pp-, and the bacterial cells are 1
It is possible to calibrate the concentration of canned mandarin orange wastewater (COD approx. 200
It has become clear that COD (0 ppm) can be easily purified to about 80 pp-. Furthermore, the dewaterability of the surplus activated sludge generated in this method is almost the same as that of conventional activated sludge, and this method was found to be a new and useful method [8]. In addition, the reason why we adopted the adhesion fixation method for immobilizing microorganisms is that when microorganisms that degrade pectin proliferate excessively, they naturally flow into the activated sludge treatment equipment of Todan, where they are assimilated by the activated sludge bacteria. This is because they acknowledged that
