Abstract

The invention relates to the technical field of nitrogen-containing wastewater treatment, and specifically discloses a sulfur filler-based composite denitrification reactor. The sulfur filler-based composite denitrification reactor comprises at least one reactor main body, wherein the reactor main body is internally filled with biofilm filler and sulfur solid filler; the reactor main body is connected with a pH (Potential of Hydrogen) regulating system; the pH regulating system is used for injecting a pH regulating agent in the reactor main body according to a pH monitoring result in the reactor main body; a water inlet and a water outlet are also formed in the reactor main body. The invention also relates to a denitrification treatment technology of high-ammonia nitrogen wastewater by applying the sulfur filler-based composite denitrification reactor. According to the sulfur filler-based composite denitrification reactor and the denitrification treatment technology, disclosed by the invention, the removal rate of total nitrogen such as ammonia nitrogen and nitrate nitrogen in sewage can be increased, the amount of sulfate radicals in the reactor can be controlled, an anaerobic ammonia oxidation process and a denitrification process can be integrated in the same reactor, and the purpose of efficient denitrification can be achieved through cooperative operation of two or three denitrification modes.

Description

technical field [0001] The invention belongs to the fields of environmental protection and chemical industry, and in particular relates to a compound denitrification reactor based on sulfur-based filler and a denitrification treatment process. Background technique [0002] In recent years, environmental problems have been perplexing people's lives. Among them, water pollution has begun to affect people's daily life. How to deal with sewage reasonably has long been concerned by the whole world. In the production of chemical plants and pharmaceutical factories, a large amount of wastewater containing high ammonia nitrogen will be produced, and chemical denitrification sometimes causes secondary pollution, and the operation is relatively complicated, while conventional biochemical denitrification requires aerobic and anoxic processes. , anaerobic and other steps. In order to control the cost of wastewater and ensure that the effluent can meet the appropriate indicators of the...
