Blast aeration system oxygenation capacity change judgment method and system based on big data

Abstract

The invention relates to a blast aeration system oxygenation efficiency change judgment method and system based on big data. The method comprises the steps of acquiring real-time water inlet parameters, aerobic pool internal parameters, air flow data and atmospheric pressure data from a sewage treatment plant; acquiring fixed parameters of a sewage treatment plant; obtaining change parameters through experimental measurement or big data fitting; through a historical data fitting method, respectively obtaining a real-time inflow BOD5 value, a tail end BOD5 value and a mixed liquid volatile suspended solid concentration value according to the chemical oxygen demand of the inflow parameters and the parameters in the aerobic tank and the concentration data of the mixed liquid suspended solid;and based on a calculation formula of the air flow data required by the sewage treatment plant, judging the change condition of the oxygenation efficiency of the blast aeration system according to theobtained data. Compared with the prior art, the method is simple and easy to implement; extra manual work and facility field operation are not needed; the application range is wide, and the like.

Description

technical field [0001] The invention relates to the technical field of judging the oxygenation capacity of a blast aeration system, in particular to a method and system for judging changes in the oxygenation capacity of a blast aeration system based on big data. Background technique [0002] Existing sewage treatment plants mostly adopt biological treatment, such as anaerobic, anoxic and aerobic, among which the aerobic process is an indispensable treatment process for most sewage treatment plants at present, and its most notable feature is that the blower is used to provide enough air , and use the air diffusion device to fill the air into the system rich in aerobic microorganisms to meet the conditions of microbial metabolic activities. The blower and air diffusion device, together with the corresponding pipeline valves and controls, etc., together form a traditional blast aeration system. The aeration system is the unit with the largest energy consumption in the sewage t...

Problems solved by technology

However, these methods are all based on the measurement of the change in the tail gas composition above the aeration tank, which requires additional measurement equipment, and with the improvement of deodorization requirements of sewage treatment plants, many aeration tanks of sewage treatment plants are covered for deodorization, resulting in Exhaust gas measurement equipment is difficult to apply
