Problems solved by technology

[0007] In addition, the above two technologies have extremely high requirements for online instruments (water inlet flowmeter, air flowmeter, inlet water online ammonia nitrogen, COD monitoring instruments, etc.), biological modules and blower control hardware equipment, so the initial investment of the control system is expensive. The post-maintenance workload is heavy and the cost is high. If equipment hardware, communication network, and online instrument failures occur, the syst

Example Embodiment

[0071] Embodiment 1: A method for precise aeration of wastewater treatment, including the following steps:

[0072] (1) Introduce the sewage to be treated into each biological pond. The biological pond is equipped with an aeration system. The aeration system includes a main control cabinet, a blower unit and aeration pipes respectively set in the biological pond. The aeration pipe is connected with the external air main pipe through the shunt pipe. The shunt pipe corresponding to each biological pool is equipped with an electric valve, and the air main pipe is equipped with a pressure gauge. The blower unit is connected to the air main pipe. The tanks are equipped with an online dissolved oxygen meter, a sludge concentration meter, a water temperature meter and an ammonia nitrogen online monitor that are electrically connected to the controller; the electric valve, blower unit and pressure gauge are respectively corresponding to the controller. Connection; there are four aerobic ...

Abstract

The invention discloses an optimization-close precise aerating method for sewage treatment. According to change of concentrations of dissolved oxygen online, aeration of biopools can be more preciselycontrolled by adjusting the aerating amounts of the biopools by adjusting the opening of an electric valve and the pressure of an air general pipe and adjusting the upper and lower limit values in adissolved oxygen concentration change area and the upper and lower limit values of the air general pipe in an optimization-close manner.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a method for approaching continuous optimization and precise aeration in sewage treatment. Background technique [0002] Wastewater biological treatment is to decompose, absorb or absorb pollutants through the metabolism of microorganisms to purify water quality. Compared with physical and chemical methods, the cost is low, the efficiency is high, and the secondary pollution generated during the treatment process is extremely small. mainstream wastewater treatment methods. In order to meet the needs of treating wastewater from different sources and different properties, various types of biological treatment processes such as anaerobic-aerobic activated sludge process, oxidation ditch method, SBR, AB method, biological contact oxidation method, BAF and so on have been developed. reactor. In these different types of processes, an aerobic treatment stage is generally incl...
