Problems solved by technology

Therefore, the removal of ammonia nitrogen is mainly through the indirect oxidation of chlorine and hypochlorous acid, the removal rate of ammonia nitrogen is high, and the area is small, but due to the large power consumption and the small amount of treatment, the self-purification of the river cannot be effectively improved. capacity and load resistance, therefore not suitable for the application of

Embodiment 1

[0047] see Figure 1-2 As shown, it is a structural schematic diagram of a preferred embodiment of the present invention, a kind of oxidation ditch river water denitrification equipment, and the soft open channel sewage interception net 4 arranged in it forms a water passageway with the coast, and there are respectively arranged in the water passageway. Flow mixer 2, push flow aerator 5, ecological floating bed 3, biological filler 7 suspended below the ecological floating bed 3, the restriction of the water passageway makes the pollutants in the water passageway less diluted and the load is larger, plus the ecological floating bed The layout makes the dissolved oxygen consumption in the watershed faster, forming an anoxic / anaerobic section. The mixed flow state is formed in the corridor through the plug-flow mixer, and then the concentration of dissolved oxygen is increased by the plug-flow aerator to form an aerobic section. , repeating the arrangement of equipment in the co...

Embodiment 2

[0050] refer to image 3 As shown, the sequence relationship between the plug flow mixer and 2, the plug flow aerator 5 and the two ecological floating beds 3 is the plug flow mixer and 2, the ecological floating bed, the plug flow aerator 5, and the ecological floating bed, and the horizontal sewage interception is used Net 6 separates it from other equipment to form a separate space. Isolate the corridor into multiple purification areas to maximize the working efficiency of the equipment, avoid affecting the deamination effect due to excessive purification range, and reduce interference factors caused by other spaces.

Abstract

The invention relates to an A / O circular treatment process, particularly relates to an oxidation ditch denitrification process and equipment for river water, and belongs to the technical field of purification of sewage. According to the special equipment for oxidation ditch denitrification process for river water, a soft open channel sewage intercepting net is arranged, a water gallery is formed along the shore, a plug flow stirring machine, a plug flow aerator and an ecological floating bed are respectively arranged in the water gallery, and a biological stuffing is suspended under the ecological floating bed; and the ecological floating bed is arranged between the plug flow stirring machine and the plug flow aerator. The denitrification efficiency is high. The oxidation ditch denitrification process for the river water is a creative process for treating rivers by using an oxidation ditch process. An A / O circular efficient treatment functional section is formed by intermittently arranging the plug flow and aerating equipment, the ecological floating bed and a biological film bed in the soft open channel sewage intercepting net and feeding compound microorganisms; by the special structural design and an outer carrier and an inner carrier of the biological stuffing, stability of the stuffing is kept to a maximum extent, and the activity of microorganisms is kept in a mixed flowing state.

Description

technical field [0001] The invention relates to an A / O cycle treatment process, in particular to an oxidation ditch river water denitrification process and equipment thereof, belonging to the technical field of sewage purification. Background technique [0002] In order to accelerate the promotion of the national "Water Pollution Prevention and Control Action Plan", namely the "Water Ten Measures", the requirements for black and odorous water bodies in the built-up areas of cities at the prefecture level and above in my country: "By 2020, the black and odorous water bodies in the built-up areas of cities at the prefecture level and above will be controlled within 10 %, by 2030, the black and odorous water bodies in urban built-up areas will be eliminated as a whole". Aiming at the problem of low removal rate of ammonia nitrogen and total nitrogen in the process of river channel governance, the subject of "Research and equipment development of an oxidation ditch river water de...
