Device and method for treating high-ammonia-nitrogen organic matter wastewater through series connection of half short-cut nitrification anaerobic ammonia oxidation and short-cut denitrification anaerobic ammonia oxidation

Abstract

A device and a method for treating high-ammonia-nitrogen organic matter wastewater through series connection of half short-cut nitrification anaerobic ammonia oxidation and short-cut denitrification anaerobic ammonia oxidation belong to the field of sewage treatment. Part of ammonia nitrogen in the high-ammonia-nitrogen organic matter wastewater is converted into nitrite nitrogen through half short-cut nitrification, then effluent of a half short-cut nitrification reactor is subjected to anaerobic ammonia oxidation reaction in a UASB granular sludge system, and ammonia nitrogen and nitrite nitrogen are synchronously removed. Anaerobic ammonia oxidation effluent containing nitrate nitrogen and high-ammonia-nitrogen organic matter wastewater entering in parallel react in a short-cut denitrification and anaerobic ammonia oxidation integrated UASB reactor, nitrate nitrogen is converted into nitrite nitrogen under the action of short-cut denitrification bacteria, then the nitrite nitrogen and the high-ammonia-nitrogen organic matter wastewater entering in parallel are subjected to anaerobic ammonia oxidation reaction, and the denitrification rate of the system is further improved. The method provides a new thought for treatment of high-ammonia-nitrogen organic matter wastewater, solves the problems of high energy consumption, low denitrification efficiency and the like, and improves the effluent quality.

Description

Technical field [0001] The present invention relates to an apparatus and method of a semi-short-term nitrated anaerobic ammonia to treat high-amamine nitrogen-based anaerobin oxidation, belonging to the field of sewage biological treatment. Background technique [0002] With the rapid development of my country and the promotion of sustainable concepts, the increasing shortage of water resources is gradually being concerned. However, a large number of water resources are used to contaminate the water due to improper handling or emissions, and the water body is most common. In today's fertilizers, the oil industry is increasingly growing, its emissions are highly valued by their high ammonia nitrogen, strong harmful, difficult difficulties, and other features. With the increasingly stringent waste of sewage discharge standards and continuous deterioration, the traditional nitrification and nitrification process can not meet the efficient and demand of energy saving, demand efficien...
