Integration automatic flow type biological nitrogen and sulfur removal reactor

Abstract

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.

Description

technical field [0001] The invention relates to an integrated self-flowing biological nitrogen and sulfur removal reactor. Background technique [0002] With the rapid development of industry and the significant improvement of economic level, the discharged wastewater tends to be diversified. In order to meet the sustainable development of ecology and economy, higher requirements must be put forward for modern wastewater treatment technology. The sulfides in sulfur-containing wastewater are toxic, corrosive and accompanied by stench. The ammonia nitrogen-containing wastewater will consume dissolved oxygen in the water body and cause eutrophication of the water body. Both of them will cause great harm to the environment. The increasingly stringent wastewater discharge standards have brought great challenges to the treatment of high ammonia nitrogen and high sulfur wastewater. [0003] The short-cut nitrification / anammox / sulfur autotrophic denitrification process is a highly ...
