Integrated carbon and nitrogen removal bioreactor

Abstract

An integrated carbon and nitrogen removal bioreactor comprises a reactor body, a pedestal, a support arranged in the periphery of the reactor body, a main water inlet tube, and a main water outlet tube connected with an outside water source, the inner chamber of the reactor body is divided into a first chamber and a second chamber which are independent through a vertical separator plate, and the first chamber is connected with the second chamber through a second water inlet tube; the first chamber is an anaerobic digestion unit used for filling anaerobic granular sludge; the second chamber is sequentially divided into a water inlet area provided with an aeration device, a short-cut nitrification unit used for filling a lightweight biological carrier, an anaerobic ammoxidation unit used for filling a suspension filler, and a water outlet area from top to bottom; the bottom of the anaerobic ammoxidation unit is provided with a second mud discharge port provided with a control valve; and the water outlet area is provided with a water outlet connected with the main water outlet tube. The integrated carbon and nitrogen removal bioreactor has the advantages of full recovery and utilization of energy contained in organic matters in wastewater, low nitrogen removal cost, and realization of comprehensive productivity in the wastewater treatment process.

Description

technical field [0001] The invention relates to an integrated carbon and nitrogen removal bioreactor. Background technique [0002] With the increasing development of social economy and the acceleration of industrialization, the wastewater discharged by many factories contains a large amount of organic matter and ammonia nitrogen, such as agricultural product processing wastewater, chemical production wastewater and anaerobic digestion liquid, which do not meet the increasingly stringent wastewater discharge standards and cause serious pollution. Water environment, leading to deterioration of water quality, further aggravating the water crisis. In addition, in today's increasingly tense energy environment, it is necessary to vigorously promote the awareness of energy conservation and emission reduction. Therefore, in order to achieve the sustainable development of economy-environment-resources, it is necessary to improve the existing wastewater treatment equipment. [0003...
