Abstract

The invention relates to a two-stage hydrolytic acidification short-cut denitrification anaerobic ammonia oxidation process for removing nitrogen by taking a granular organic matter as a carbon source, and belongs to the field of biological sewage treatment. The whole device comprises a water inlet tank, a sequencing batch hydrolytic acidification in-situ short-cut denitrification reactor, a middle water tank, a granular organic matter storage tank, a sequencing batch anaerobic ammonia oxidation reactor and a PLC automatic control system. The whole device adopts a two-stage hydrolytic acidification short-cut denitrification and post-anaerobic ammonia oxidation process, and is matched with a PLC automatic control system, so that the intelligence and the flexibility of the operation of the whole process are improved, and efficient removal of nitrogen is realized.

Description

technical field [0001] This research involves a two-stage hydrolytic acidification short-range denitrification anammox process using particulate organic matter as a carbon source to achieve nitrogen removal, which belongs to the field of wastewater biological treatment. Background technique [0002] With the discovery and research of short-range denitrification technology, the anammox process with short-range denitrification as the nitrite supply route has become a research hotspot; compared with the nitrification and denitrification process, the sludge The output has been reduced by 84%. Compared with the short-range nitrification anammox process, although an additional 0.78mg / L short-range denitrification carbon source is required, it still saves 45% of aeration energy consumption and about 80% compared with traditional biological denitrification. The addition of organic carbon sources provides a new idea for the simultaneous treatment of domestic sewage and industrial nit...
