Abstract
The invention discloses integrated treatment equipment for rural aquaculture sewage with high-concentration COD (Chemical Oxygen Demand) and ammonia nitrogen and relates to the technical field of sewage treatment equipment. The integrated treatment equipment comprises a UASB (Upflow Anaerobic Sludge Blanket) reactor, an anoxic pool, an aerobic pool, an active-carbon filler pool, an MBR (Membrane Bioreactor) reaction pool and a disinfection pool which are connected in sequence, wherein a sewage inlet is arranged at the lower part of the UASB reactor, and the UASB reactor is communicated with the anoxic pool by a first water outlet; the anoxic pool is communicated with the aerobic pool by a second water outlet; the aerobic pool is communicated with the active-carbon filler pool by a third water outlet; the active-carbon filler pool is communicated with the MBR reaction pool by a fourth water outlet; the MBR reaction pool is communicated with the disinfection pool by a fifth water outlet,and a treated-water outlet is arranged at the lower part of the disinfection pool. The integrated treatment equipment disclosed by the invention is designed according to the water-quality characteristics of high COD, high ammonia-nitrogen content, high total-nitrogen content and poor biochemical property and the like in the rural aquaculture sewage, and the problems of difficult treatment and badtreatment effect of the aquaculture sewage due to high-concentration COD and high ammonia nitrogen in the existing rural aquaculture sewage are solved.
