Embodiment 1

[0044] Example as figure 1 Shown, the running operation procedure of technique of the present invention:

[0045] In the water inlet process a, the wastewater to be treated first enters the SBR reactor under the adjustment of the real-time control device, so that the activated sludge deposited at the bottom of the reaction tank is boiled and fully mixed with the raw water. When the reactor is filled or reaches the specified liquid level Stop water injection and enter the first aeration process.

[0046] In the first aeration process b, turn on the blower for aeration, and control the aeration volume to 0.6m 3 / h, the compressed air provided by the blower enters the aerator through the intake pipe, and efficiently supplies oxygen to the activated sludge mixture in the form of tiny bubbles, and makes the sewage and activated sludge fully contact, the purpose is to use the activated sludge Microorganisms degrade organic pollutants and complete short-range nitrification of nitro...

Abstract

The invention discloses a SBR alternant aerobic/anaerobic technology for biological denitrification and real time control device and method thereof which consists of, dividing the waste water to be treated into three portions, loading each portion into a reactor, alternatively carrying out the operating mode of aerobic aeration and anoxybiotic agitating under real time procedure control, so as to realize the organics degradation and nitrogen-containing compound removal.

Description

technical field [0001] The invention relates to a sewage treatment process, a control device and a method, in particular to a sewage biological denitrification process, a control device and a method. Background technique [0002] The SBR method is the abbreviation of the intermittent activated sludge water treatment method. Its treatment device is connected to the water inlet pipe, the outlet pipe and the sludge discharge pipe by the SBR reaction tank. There is only one reaction tank and the floor area is small. It is a conventional activated sewage Mud wastewater treatment process. However, due to incomplete nitrification in this activated sludge process, denitrification hardly occurs, and the removal rate of total nitrogen is only between 10% and 30%. For urban sewage and nitrogen-containing industrial wastewater, if the conventional activated sludge method is used for treatment, the effluent also contains a large amount of nitrogen and phosphorus, and the phenomenon of "...
