As part of this research work, an efficient and environmentally friendly
technology for the disposal of organic wastes based on vermiculture of the California
worm (Eisenia fetida) has been substantiated and developed. The developed
technology allows not only to fully utilize vegetable raw materials, but also to obtain
a valuable fertilizer for increasing yields (biohumus) and a source of animal protein
for food (worm biomass).
The studies have made it possible to determine the most rational parameters of
the substrate for cultivation of the California red worm (Eisenia fetida), which will
significantly increase the yield of free humic acids, and therefore - to improve the
quality of biohumus (pH = 6.5 -7.0, temperature - 18 -25 ° C, humidity -70-80%).
It is experimentally found that the best variant of solid organic substrate on
which the red worm (Eisenia fetida) is cultivated, as well as undergoing the most
efficient disposal of waste is potato peel, cabbage, apple peel, tea in a ratio of
2:1:1:1:1.
It is found that the best variant of the substrate based on wastewater MPP and
activated sludge is the option with a weight ratio.Studies have shown that the
cultivation of the California worm (Eisenia fetida) on plant substrates processes of
destruction of dietary fibers.
Technology for the disposal of organic food waste and WFP waste and activated
sludge using the cultivation of the red California worm (Eisenia fetida) has been
developed, and each step of the technological process has been described, indicating
the optimal technological parameters obtained through experimental studies
