NOVELTY - Waste filtrate of household waste burning plant is processed by (A) preprocessing waste filtrate with high-concentration suspensions and calcium ions; (B) making preprocessed outlet water flow in middle water tank, pumping in anaerobic bioreactor for processing, separating generated methane by; (C) carrying out anoxic biological treatment, one-stage aerobic biological treatment, 2-stage aerobic biological treatment and deposition treatment to outlet water; and (D) processing outlet water after deposition treatment by membrane bioreactor to remove organics and ammonia nitrogen.    USE - Method for processing waste filtrate of household waste burning plant.    ADVANTAGE - The method does not need to configure sludge backflow system and add carbon source. The residual sludge production rate can be reduced by 40-50% compared with conventional active sludge processing system.    DETAILED DESCRIPTION - Waste filtrate of household waste burning plant is processed by (A) preprocessing waste filtrate with high-concentration suspensions and calcium ions by coagulating sedimentation method and carbon dioxide adding deposition method under alkali condition; (B) making preprocessed outlet water flow in middle water tank, pumping in anaerobic bioreactor for processing, separating generated methane by 3-phase separator, and collecting; (C) carrying out anoxic biological treatment, one-stage aerobic biological treatment, 2-stage aerobic biological treatment and deposition treatment to anaerobically biologically processed outlet water, where outlet water after two-stage aerobic biological treatment reflows to anoxic biological treatment period; and (D) processing outlet water after deposition treatment by membrane bioreactor to remove difficultly degradable organics and ammonia nitrogen so as to ensure that outlet water meets first-level standard of synthetical draining standard of sewage.    DESCRIPTION OF DRAWING(S) - The drawing is a schematic diagram illustrating a method for processing waste filtrate of household waste burning plant.
