Novel intelligent aeration method

Abstract

The invention relates to the technical field of sewage treatment processes, in particular to a novel intelligent aeration method. The method comprises a dissolved oxygen measuring point placed in themiddle of an aeration tank, and a template sedimentation tank used for holding outlet water of an aerobic tank, wherein the front part of the sedimentation tank is equipped with an inclined plate or an inclined pipe to increase a sedimentation area. The method comprises the following steps: the first step, acquiring sewage plant inlet water quality parameters, biochemical tank parameters, simulation inclined plate or inclined pipe sedimentation tank outlet water parameters, and sewage plant outlet water quality parameters, and saving the parameters to a database; and the second step, comparingsimulation inclined plate or inclined pipe sedimentation tank outlet water actual parameters with set values. Compared with the prior art, the method has the advantages that supplied oxygen at the end of the aeration tank often has a surplus, if a dissolved oxygen probe is moved forward, a dissolved oxygen situation in the aerobic tank can be more clearly understood, so that a system program canadjust an aeration situation in time and effectively, and "precise aeration" is truly achieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment technology, in particular to a novel intelligent aeration method. Background technique [0002] As the country's environmental protection requirements become more and more stringent, there are more and more sewage treatment plants in China. There are currently more than 6,000 large-scale municipal sewage plants, and there are more industrial ones. So many sewage plants were built almost within 10 years, but the related design technology and operation management technology are relatively lagging behind, and the personnel of operation management can't keep up. Most of the sewage plants are in a state of extensive management. The energy consumption of the aeration system accounts for about 60% of the overall energy consumption of the entire sewage plant. Not only is a large amount of electric energy wasted, but also the aeration volume cannot be dynamically adjusted according to the influen...

Problems solved by technology

[0003] There are also companies on the market that promote precision aeration technology, but their technology has obvious flaws: too much reliance on in-line meters, flow meters, and precisely regulated valves

These online gauges tend to drift over time, and then lose accuracy, and the "precise aeration" scheme based on reading these gauges will not work stably; A sewage plant sets a model and optimizes the model over time, but once the effluent standard changes or the influent parameters change greatly, such a model is not applicable, that is, the model has a certain scope of application
