The invention provides a full-amount resourceful treatment method for kitchen waste coalification
sewage, according to the method,
grease is obtained through oil-water separation, the
grease can be used as a
raw material to prepare
biodiesel, and a mature process exists; the
sewage subjected to oil-water separation is subjected to
adsorption separation and
ultrafiltration to recover residual coalification
slag and the like;
organic acid is extracted from the
sewage passing through the
ultrafiltration system by using
ion exchange resin, and the
organic acid can be used as a
carbon source to be supplemented into a biochemical treatment process of a sewage
plant, so that the
denitrification effect of biochemical treatment of the sewage of the sewage
plant can be improved; the sewage passing through the
ion exchange resin enters a
nanofiltration system to be treated, because the whole treatment process is carried out in a totally-closed mode and is free of infectious microbe infection,
nanofiltration concentrated liquor is in a sterile state, and the intercepted concentrated liquor contains high-concentration carbohydrates,
starch,
protein and other substances. The microbial culture medium is a
nutrient medium for growth and
reproduction of microorganisms and mainly comprises carbohydrates,
nitrogen-containing substances,
inorganic salts, water and the like, so that the
nanofiltration concentrated liquid can be used as a
raw material of the microbial culture medium to be directly utilized in related industries of
fermentation; the nanofiltration liquid passes through a
reverse osmosis system, and the
clear liquid reaches the
reclaimed water reuse standard and is recycled, so that
water resources are saved, and full-amount recycling of coalification sewage is realized.
