Description
Technical Field
The invention relates to the technical field of sewage treatment, in particular to an automatic control system based on an anaerobic ammonia oxidizing bacteria process.
Background
In the traditional biological denitrification process for sewage treatment, nitrogen removal is realized through two independent processes of nitrification and denitrification. The traditional theory considers that the types of bacteria for nitrification and denitrification are different from the required environmental conditions, nitrifying bacteria mainly take autotrophic bacteria as main materials, and higher dissolved oxygen is required in the environment; on the contrary, denitrifying bacteria mainly comprise heterotrophic bacteria, and are suitable for growing in anoxic environments. The anaerobic ammonia oxidation process breaks through the basic theoretical concept in the traditional biological denitrification process. Under anaerobic conditions, ammonia is used as an electron donor, nitrate or nitrite is used as an electron acceptor, and ammonia is oxidized into nitrogen, so that the oxygen supply is saved by more than 60% compared with the whole-process nitrification. The use of ammonia as an electron donor also saves the carbon source required in the traditional biological denitrification process. Meanwhile, the cell yield of the anaerobic ammonia oxidation bacteria is far lower than that of denitrifying bacteria, and the sludge yield in the anaerobic ammonia oxidation process is only 15% of that in the traditional biological denitrification process.
The optimal pH range of the anaerobic ammonia oxidation reactor is 7.65-8.25, the filter tank shows good denitrification performance in the range, higher or lower pH water can bring obvious negative influence to the operation of the reactor, the pH adjustment in the anaerobic ammonia oxidation reactor is carried out by adding acid liquor or alkali liquor through manual operation equipment at present, the process has high manpower consumption, the quality requirement on staff is high, and the manual adjustment of the pH of sewage is inaccurate.
