Problems solved by technology
The principle of ANAMMOX (anaerobic ammonium oxidation) is that under anaerobic conditions, NO 3 - As electron acceptor, converts ammonia to N 2 , and their combination and other new biological denitrification processes have solved the problems existing in the traditional nitrification-denitrification process to a certain extent, but due to the harsh reaction conditions, they are still in the stage of laboratory research, and it is difficult to apply them in engineering.

Embodiment Construction
[0022] The principle and process of the present invention will be further described below in conjunction with the accompanying drawings.
[0023] figure 1 The flow chart of photosynthetic carbon supply ecological denitrification process provided by the present invention. The water 1 to be treated first enters the first subsurface flow wetland 3, and then flows into the plant algae aeration growth tank system composed of one or more plant algae aeration growth tanks 5, and the water flowing through the plant algae aeration growth tank system passes through the water pipe 6 enters the sedimentation tank 7, flows through the sludge return pipe 8 and the return pump 10 to the first subsurface wetland 3; the effluent from the sedimentation tank flows into the final subsurface wetland 9, and flows out of the treatment system after being sterilized.
[0024] Plants such as canna, reed or cattail are planted in the first subsurface wetland, and the main function is to achieve denitri...

The invention discloses an ecological denitrify technology of photosynthetic carbon-supplying, which is characterized by the following: inputting the disposed water into underflow wetland; making water pass algae growing pool of aerating plant into sedimenting pool; refluxing mud to first-segment underflow wetland; flowing water from sedimenting pool to next-grade underflow wetland; flowing out of disposing system after sanitizing; utilizing natural attribute of algae photosynthesis completely to fix carbon in the air; supplying the needed carbon source in the denitrifying course through plant and algae metabolism product and living body degraded product; recycling carbon without secondary pollution; possessing negative feedback function and good stability; making urban effluent reach surface-water III standard.
Description
technical field [0001] The invention relates to a process method for removing nitrogen in organic micro-polluted water such as landscape water and reclaimed water by using a biological method, and belongs to the technical field of water treatment. Background technique [0002] Water rich in phosphate and some forms of nitrogen can cause excessive growth of plankton such as algae in the water body under suitable light and other environmental conditions, and then the death of the algae and the metabolism of heterotrophic microorganisms deplete the water body The dissolved oxygen in the water caused the deterioration of the water quality and the destruction of the structure of the aquatic ecological environment, which is the so-called eutrophication of the water body. Limnologists believe that natural eutrophication is a manifestation of water body aging, and excessive plant nutrients nitrogen and phosphorus entering the water body are artificially accelerating the eutrophicati...
