The invention provides a municipal
sludge fermentation aid and a use method thereof. The municipal
sludge fermentation aid comprises 10-30 parts of
coal ash, 20-50 parts of a
chitosan derivative, 5-30parts of aluminum
sulfate, 10-30 parts of a bio-
enzyme, 5-30 parts of
ferric trichloride, 20-50 parts of a zymophyte
yeast, wherein the parts are 100 parts in all. The
fermentation aid provided by the invention can be compounded with a biological flocculant zymophyte
yeast, and in addition, is capable of dehydrating
sludge before fermentation, and thus the situation that growth and propagation ofaerobic
bacteria are affected because of too much
moisture in the sludge can be avoided; due to adoption of inorganic and organic flocculants, a framework can be established inside the sludge to maintain fluid channels, the interference tension of solids and liquids can be reduced,
moisture in sludge floc grids can be released, and deep removal of the
moisture in the sludge can be facilitated; meanwhile, due to interactions of organic matters and zymophyte, the reaction process of
compositing can be accelerated, and the
compositing reaction time can be shortened; and the municipal
sludge fermentation aid has the advantages that
dehydration is rapid, the composting reaction process is accelerated, the composting reaction time is shortened, the requirements of users can be well met, and thelike.
