Process for purifying and recycling biomass organic wastewater

The invention discloses a process for purifying and recycling biomass organic wastewater and belongs to the technical field of treatment and recycle of wastewater. The process comprises the following steps: (A) carrying out hydrolysis acidification, i.e. carrying out hydrolysis acidification treatment on the biomass organic wastewater for 2.5 to 5 hours; (B) carrying out anaerobic treatment, i.e. adopting an anaerobic composite reactor the level of which is over three, wherein the inside of the anaerobic composite reactor is provided with a combination body of an upflow anaerobic activated sludge bed and an anaerobic filtering media and filler biological film bed and is also provided with a distributor; (C) carrying out aerobic contact, i.e. adopting an aerobic tank which is internally provided with a combination band of an aerobic filler biological film and aerobic activated sludge so as to purify the wastewater, or carrying out wetland treatment or land treatment, i.e. purifying the wastewater by the physics, materialization, chemistry and biochemistry (anaerobic, facultative and aerobic bacteria, microorganism, animals and plants) composite actions which the wetlands or the lands have. The process of the invention has the advantages of wide application range, small energy consumption, little equipment, low price, simple management, easy operating control and smelling and tasting control, simple and clear scheme design and easy construction and installation and is suitable to carry out treatment and recycle on the wastewater in rural areas and the organic wastewater generated by enterprises using animals and plants as raw materials.
