Problems solved by technology

However, this process is only suitable for high ammonia nitrogen wastewater, and the effluent TN of high nitrate wastewater cannot meet the standard
Moreover, the living environment of anaerobic ammonium oxidation and short-range denitrification bacteria is slightly different, and the two bacteria cannot survive in the best environment for each, and the activity of anaerobic ammonium oxidation is easily affected by the external environment, so the system is not stable enough

Embodiment

[0054] like Figure 1-5 As shown, using this process to treat sludge digestion liquid (temperature at 30°C), the organic matter in the influent comes from the small molecular organic matter in the anaerobic digestion effluent, which is used as a carbon source for short-range denitrification, no additional carbon source is needed, and the sewage passes through the water inlet pipe 10 Entering the nitrite nitrogen accumulation area, the sludge treated in this area is short-range nitrification-short-range denitrification granular sludge, which converts nitrate nitrogen and part of ammonia nitrogen in sewage into nitrate nitrogen, providing a substrate for anaerobic ammonia oxidation, The sewage enters the anammox area from the nitrite accumulation area through the phosphorus removal filler. The phosphorus removal filler is alkali-modified sponge iron, which can be used as an oxygen scavenger to absorb part of the oxygen, and can also be used as a phosphorus removal filler to adsor...

Abstract

The invention discloses an efficient and deep integrated treatment system for high-ammonia-nitrogen and high-nitrate-nitrogen wastewater, and belongs to the technical field of industrial wastewater treatment. The system comprises a reactor, a first reaction tank, a second reaction tank and an electric flocculation tank. Every two of the reactor, the first reaction tank, the second reaction tank and the electric flocculation tank are sequentially communicated. A flow pusher is arranged on the inner side wall of one end of the reactor. A first flow guide plate, a first partition plate, a second partition plate and a second flow guide plate are sequentially arranged in the reactor from top to bottom. An online NH<+>-N electrode and an online NO<->-N electrode are further arranged on the reactor, and the online NH<+>-N electrode and the online NO<->-N electrode are electrically connected with an external power source through wires. An anode plate and a cathode plate are respectively arranged in the electric flocculation tank, and the anode plate and the cathode plate are respectively and electrically connected with the external power source through wires. The denitrification advanced treatment integrated device provided by the invention is used for treating sewage, and can realize efficient denitrification, save a carbon source and realize aeration.

Description

technical field [0001] The invention relates to an efficient and deep integrated treatment system for waste water with high ammonia nitrogen and high nitrate nitrogen, and belongs to the technical field of industrial waste water treatment. Background technique [0002] With the improvement of human living standards, the rapid growth of population, and the rapid development of industry, the discharge of sewage is increasing day by day, and the pollution of water environment is becoming more and more serious. The denitrification and phosphorus removal of sewage has become a hot spot for experts and scholars at home and abroad. However, in the actual application process of the traditional biological nitrogen and phosphorus removal process, the phenomenon that the nitrogen removal effect and the phosphorus removal effect cannot be achieved at the same time often occurs, and there are problems such as large energy consumption, complicated process, low efficiency of nitrogen and ph...
