Integration automatic flow type biological nitrogen and sulfur removal reactor

The invention discloses an integration automatic flow type biological nitrogen and sulfur removal reactor. The reactor comprises a reactor body, a base, a support arranged on the base, a water inlet pipeline and a water outlet pipeline. The reactor body is installed on the base. The water inlet pipeline and the water outlet pipeline are installed on the support. The reactor body is communicated with an outside water source through the water inlet pipeline. An inner cavity of the reactor body is divided into a first cavity body and a second cavity body through a vertical partition plate. The first cavity body is sequentially divided into a primary water inlet area, a short-cut nitrification unit, an anaerobic ammonia oxidation unit and a secondary water inlet mixing area from top to bottom. The second cavity body is sequentially divided into a sulfur elementary substance recovery area, an anaerobic ammonia oxidation coupling sulfur autotrophic denitrification unit, a water outlet area and a gas collecting area from bottom to top. The integration automatic flow type biological nitrogen and sulfur removal reactor has the advantages that nitrogen and sulfur can be removed at the same time, and the occupied area is small; the purpose of waste recovery is achieved while one hundred percent conversion is realized, and the method is efficient and thorough; no extra carbon source is needed; meanwhile, water flow basically depends on gravity, so that power consumption is reduced, and the method is economical and reasonable.
