The invention relates to a kitchen waste
water treatment method and a treatment device thereof. The kitchen waste
water treatment method comprises the steps that firstly, waste water is pretreated through a pretreatment integrated device to obtain supernate, secondly, the supernate is treated through a composite anaerobic tank to obtain degraded
clear liquid, then the degraded
clear liquid is subjected to
phosphorus removal treatment through a
phosphorus removal reactor to obtain
phosphorus removal
clear liquid, the dephosphorized clear liquid is treated in a
denitrification-
carbonization-
nitrification-short-
cut nitrification-
denitrification mode in sequence, a mud-water mixture is obtained, and then the mud-water mixture is subjected to mud-water separation through a built-in dynamic membrane unit. The device is integrated equipment, the equipment is small in installation occupied area, high-
automation treatment of the equipment is achieved, and the
wastewater treatment efficiency and effect are better improved. According to the method, the medicament treatment cost can be reduced, the flocculent
precipitation effect is enhanced, automatic chain feeding is realized, the
automation degree of equipment is improved, and accurate adjustment is realized. By adopting a two-stage
ammonia nitrogen removal process, the consumption can be better reduced, and the
ammonia nitrogen removal efficiency is improved.
