Embodiment 1

[0038] See attached figure 1 , Methanogenic anammox integrated carbon and nitrogen removal device: equipped with a cylindrical reaction device, water inlet system, temperature control system, dosing system, pH monitoring system, gas collection system, and light protection system. The cylindrical reactor (24) has an effective volume of 5L and is provided with 4 sampling ports (23). The water inlet system communicates with the water inlet (18) at the bottom of the cylindrical reactor through the water inlet tank (1), the peristaltic pump ① (2), and the water inlet pipe (5), and the water flow is upward. The temperature control system consists of a temperature controller (10), a temperature control probe (11), and a heating belt (12). The water contact, the heating belt and the temperature probe are all connected to the temperature control device to monitor and control the reaction temperature. The dosing system communicates with the drug inlet (19) and the drug inlet pipe (15)...

Abstract

The invention discloses a device and method for realizing methane production and anaerobic ammonia oxidation integrated carbon and nitrogen removal, and belongs to the field of wastewater treatment. The main body belongs to a biological filter process and is provided with a cylindrical reaction device, a water inlet system, a temperature control system, a dosing system, a pH monitoring system, a gas collection system and a light-shielding protection system. According to the implementation of the methane production and anaerobic ammonia oxidation integrated carbon and nitrogen removal process,essentially, layered culture and optimization of different functional florae (mainly including two major types, namely, methane production related florae and anaerobic ammonia oxidation bacteria) arecarried out in a filter tank, that is, different microorganisms are cultured at different filter material heights, and the methane production related florae are located at the lower part of the filtertank, and the anaerobic ammonia oxidation bacteria are located at the upper part. Sewage enters the reaction device from bottom to top, organic matter removal and methane production are conducted firstly, then denitrification is conducted through anaerobic ammonium oxidation bacteria, and finally simultaneous carbon removal, denitrification and methane production in the single reaction device areachieved.

Description

technical field [0001] The invention relates to a sewage treatment technology, specifically a device and method for realizing the integrated carbon and nitrogen removal of methane-producing anaerobic ammonium oxidation, which is suitable for the treatment of organic matter and nitrogen in urban domestic sewage, and can generate usable methane energy. The whole treatment process is kept in an anaerobic state, which is beneficial to economically and effectively controlling water body organic matter and nitrogen pollution, saving sewage treatment costs, and belongs to the field of waste water treatment methods. Background technique [0002] With the rapid development of industry and agriculture and the improvement of people's living standards, water environment problems have attracted more and more attention. The traditional activated sludge method is a sewage denitrification method commonly used in sewage treatment plants, mainly including the nitrification-denitrification pro...
