Post-sulfur autotrophic nitrogen removal integrated domestic sewage treatment equipment

The invention relates to post-sulfur autotrophic nitrogen removal integrated domestic sewage treatment equipment, which consists of units such as a hydrolytic acidification area, a contact oxidation area, a high-efficiency settling area and a post-sulfur autotrophic nitrogen removal filter tank, and is supplemented with an aeration device, MBBR (Moving Bed Biofilm Reactor) biological filler, sulfur autotrophic filter tank biological filler, a filter tank supporting layer, a backwashing and blowback system, high-efficiency inclined tube filler and the like. The efficient settling zone is used for mud-water separation, the post-sulfur autotrophic nitrogen removal filter tank is used for removing total nitrogen, an external carbon source is not needed, the efficiency is high, energy is saved, the environment is protected, and the device has the advantages of being easy to manufacture, convenient to install and small in occupied area; the method is suitable for treating the domestic sewage with low C/N ratio, the
