Study On The Reliability And Operation Management Measures Of Automatic Online Monitoring System Of The Sewage Treatment Plants In Benxi City

In recent years, with the rapid development of our country, the economy in BenxiCity also gets the rapid development. Benxi City introduces the investment of manyfamous enterprises, which brings new challenges to the environmental protectionmanagement department, simultaneously. It is the significant problem for the relevantenvironmental management departments in Benxi to consider that in order to bring theeconomic benefit in the meantime of protecting the environment well, how to makeuse of pollution source automatic online monitoring technology to establish andimprove the reasonable and effective online monitoring management mechanism.This paper is based on the data provided by pollution source automatic onlinemonitoring system, focuses on studying the sewage treatment plants in Benxi city,analyzes the data validity validation. Moreover, this paper focuses on studying theCOD dynamic change of the sewage treatment plants in Benxi city, quality assurancemeasures and operation assessment management of pollution source automatic onlinemonitoring system, and obtains the conclusions as follows.1. The quality management of pollution source automatic online monitoring systemis divided into two aspects such as quality assurance (QA) and quality control (QC). Itis concluded that QC has more operability in the data validity discrimination, andintuitively reflects instrument accuracy and data validity, furthermore, QA runsthrough the entire water quality in the online monitoring process, and is the basicguarantee of the quality management by studying the quality management of pollutionsource automatic online monitoring system for three sewage treatment plants in Benxicity.2. The data calculated by the checking working condition method and onlinemonitoring data have a good consistency. But there exists relatively larger deviationas comparing the data of manual monitoring method and online monitoring data. Itcan be seen that the amount of COD discharge calculated by the checking workingcondition method has good accuracy and applicability, hence, the checking workingcondition method is an effective method for the application of the low frequencymonitoring data in the total amount of measurement. 3. The COD inlet concentration dynamic change of the sewage treatment plant inBenxi is affected by the main factors such as water amount change during theabundant, flat and dry periods, and the work and rest time of residents living water.And the COD outlet concentration dynamic change of the sewage treatment plant inBenxi is affected by the main factors such as the process change of sewage treatmentplant and the inlet water quality concentration.
