Application Study On On-line Monitoring System Of Waste Water Treatment Plants In Guangzhou

Our country's economic construction is rapidly developing and the people's environmental protection consciousness is daily enhancing, so the technique of on-line monitoring begins to be used in water quality monitoring of sewage treatment plants.First, the article analyzes water quality on-line monitoring application status at home and abroad. Take the water quality on-line monitoring system of sewage treatment plants in Guangzhou for instance, the article investigates component,principal,main technical issues and function of the system in depth.Second, the article does the competitive experiment(on-line monitoring and hand testing), and applies the method of mathematical statistics on the result. The result expresses that the data monitored by on-line monitoring system is true, can be used in waste water plant's supervision and operation.At last, the article studies of LieDe 's second phase(UNITANK),and researches and discusses that how to apply on-line monitoring system in waste water plant's optimal operation. Point is to study how to apply on-line monitoring system to economically control air flux without influence the removal ratio of organic substance and NH3-N. The result expresses that applying on-line monitoring system can economically control air flux, and obtains better economic benefit.
