| Abstract: | The biotechnique of external air lift reactor (EALR) was used for the treatment of monosodium glutamate processing wastewater to produce a single cell protein (SCP ) with Rhodopseudomonas spieroides. The removal of BOD5 was 92% under the following conditions:BOD5, 2750mg/ L in the in fluent; KLa.,242h-1; HRT,12h;and the concentration of charcoal particle as a carrier, 10g/ L. The species of microorganism, R. sphaoha,has a protein content of up to 67.2 % and a coefficient of SCP yield of 0.59kg(cell)/(kg BOD5·d ).The process has a biological load of 1. 68kg BOD5/(kg MLSS·d),which is higher than that either in an activated sludge process or in a PSB 4-stage system. |
