Example Embodiment

[0022] The present invention will be described in further detail in conjunction with the accompanying drawings and embodiments.

[0023] like figure 1As shown, a technology of using sludge fermentation to strengthen the partial nitrification anaerobic ammonium oxidation of continuous-flow urban sewage is equipped with a raw water tank (1), a continuous-flow AAO reactor (2), a sedimentation tank (3), and sludge fermentation Tank (4); raw water tank (1) includes water inlet pipe (1.1), outlet pipe (1.2) and vent pipe (1.3); outlet pipe (1.2) passes through peristaltic pump (1.4) and continuous flow AOA reactor (2) connected; the continuous flow AOA reactor (2) includes 8 cells, which are divided into 2 cells anaerobic section (2.1), 4 cells anoxic segment (2.2), and 2 cells aerobic segment (2.3) according to the direction of water flow. To prevent the occurrence of short flow, each compartment is connected with a short pipe; the aerobic compartment (2.3) is continuously air-fil...

Abstract

The invention discloses a device and a method for realizing short-cut nitrification coupled anaerobic ammonia oxidation denitrification in a sewage treatment continuous flow process through a sludge fermentation product, and belongs to the field of sewage treatment. The device mainly comprises a sewage raw water tank, a sludge fermentation product storage tank, a sewage treatment continuous flow reactor and a sedimentation tank. The sewage treatment continuous flow reactor in the method comprises continuous flow reactors in all forms in sewage treatment, and mainly inhibits the activity of NOBthrough the sludge fermentation product, so that an aerobic section in the continuous flow is subjected to a short-cut nitrification reaction. The method is simple and feasible, can solve the problemthat short-cut nitrification of a continuous flow process is difficult to realize, can provide nitrite nitrogen for denitrification and anaerobic ammonia oxidation, and achieves the purposes of saving energy and reducing consumption.

Description

technical field [0001] The invention discloses a device and method for realizing short-range nitrification coupled with anaerobic ammonium oxidation denitrification through sludge fermentation products in a continuous flow process of sewage treatment, which can realize short-range nitrification effect while reducing sludge, and is suitable for cities in my country The current situation of sewage C / N is relatively low, saving energy, saving energy and reducing consumption. Background technique [0002] With the continuous development of our country's society and economy, people's living standards are increasing day by day, and the accompanying acceleration of urbanization has led to an increase in the discharge of domestic sewage. The organic matter and nitrogen, phosphorus and other pollutants contained in domestic sewage will cause eutrophic oxidation in rivers, lakes and other water bodies after being discharged into water bodies, and destroy the original water environment ...
