Embodiment

[0050] Such as figure 1 As shown, the integrated short-range denitrification anammox water treatment system includes a nitrate wastewater pretreatment water tank 10, an urban sewage dilution water tank 20, a mixed wastewater water tank 30, an organic nitrogen source water tank 40, and a UASB biofilm reactor 50. Water return system 60 and air return system 70.

[0051] continue to see figure 1 , the water outlet of the nitrate wastewater pretreatment water 10 is connected with the water inlet pipe of the mixed waste water tank 30 through the first water inlet pump 81, and the water outlet of the urban sewage dilution water tank 20 is connected with the mixed wastewater water tank 20 through the second water inlet pump 82. The waste water tank 30 is connected to the water inlet pipe, and the water outlet of the mixed waste water tank 30 is connected to the water inlet pipe of the UASB biofilm reactor 50 through the third water inlet pump 83, and the organic nitrogen source wate...

Abstract

The invention belongs to the technical field of sewage biological denitrification treatment, and particularly relates to a quick start method and system for integrated short-range denitrification anaerobic ammonia oxidation for water treatment. The method includes the steps of pretreating industrial nitrate wastewater, deploying urban domestic wastewater, mixing the wastewater and performing a coupled reaction of short-range denitrification and anaerobic ammonia oxidation. The system includes a nitrate wastewater pretreating water tank, an urban wastewater diluting water tank, a wastewater mixing water tank, an organic nitrogen source water tank, and a UASB biofilm reactor. The technical solution provided by the invention can realize the quick start of the in-situ coupled reaction of short-range denitrification and anaerobic ammonia oxidation for the treatment of the industrial nitrate wastewater and the urban domestic sewage through control of water inlet modes and parameters in start-up stages, and realize high-efficiency and deep removal of nitrogen and carbon, and is an economical energy-saving wastewater biological treatment process with great application prospects and value.

Description

technical field [0001] The invention belongs to the technical field of sewage biological denitrification treatment, and in particular relates to an integrated short-range denitrification anammox water treatment quick start method and system. Background technique [0002] Today in the 21st century, with the rapid development of industry and the rapid increase of population, a large amount of industrial nitrate wastewater and urban domestic sewage are produced, nitrogen pollution is becoming more and more serious, and the quality of my country's water environment is not optimistic. [0003] The traditional biological denitrification process can no longer meet the future energy-saving, efficient denitrification and sustainable development requirements of urban sewage plants. As an incomplete denitrification reaction, short-cut denitrification can save carbon source demand, reduce sludge production, and improve nitrogen conversion rate. It is considered to be the most research p...
