Description

Duct

Filling volume

fermenter air flow

The fermentation unit consists of a fermenter equipped with a mechanical agitator, a barbaterier air detection system, a barbater, a control unit with an LNG unit for temperature control and regulation, as well as a System for the continuous feeding of the nutrient substrate (PDB) and selection of the culture liquid.

The cultivation temperature is maintained at 3.7 ° C ± jl ° C ,, 4 ± 0.2, the duration of the experiment is 76 hours while the preservation in the fermenter is 3: h. ;.

Example. The post-yeast brew of the Krasnoyarsk Biochemical Plant is subjected to cleaning. As bio-oxidants use. mixed culture of the microorganisms of the species Pseudobacterium sp, Lactobacterium reich and Micococcus alb.

The results of the ekapimene are given in table. one..

On the basis of the obtained data, one can draw the following conclusions: the degree of purification of PDB by a mixed culture of microorganisms of the species Pseudobacterium sp, Lactpbacterium leich and Micococcus alb reaches 62 68% 1Ü H1G (} ШШ Чб1ЖБмуму oxygen consumption): utilization of residual Sugars is 70-72.3 %

Thus, if with a residence time of a PDP in the enzyme of 1-1.5 hours, the effectiveness of cleaning the PDB with fungal microflora does not exceed 26% of COD and eat an additional biomass of more than 4.95 tons / sdt, then after the introduction of a polycult Comparative data on the degree of purification After-seasoning brazka at different loads on the flow of known and proposed methods are given in Table. 2. Time for wastewater recuperation, in the fermenter 1.0-1.5.
