Oxidize the ditch craft in dirty water handle of application and development

Summary: This text expatiated primarily the Carrousel oxidizes the construction, craft mechanism of the ditch and circulate the problem exsited in the process with the homologous the method of solution.Finally, introduce the Carrousel oxidize the latest research progress of the ditch and pointed out the future and main research direction.

Key phrase: The Carrousel oxidizes the ditch divideds by the phosphor takes off the nitrogen construction mechanism

Application and Development of Carrousel Oxidation Ditch Process on Wastewater Treatment

Abstract: The structure and the techniques of carrousel oxidation ditch process on nitrogen and phosphor removal are introduced in this paper. The problems inrunning and their corresponding resolvent are also pointed. At last, The authorshowed the up to date research improvement and the mainly future research dire-ction Key words: Carrousel; oxidation ditch; nitrogen and phosphor removal; structure;techniques

1. Foreword

Oxidize the ditch oxidation ditch again a continuous circulation

spirit pond Continuous loop reactor, is a live and dirty mire method a kind of to transform.Oxidizing the dirty water in ditch handles the craft be researched to manufacture by the hygiene engineering graduate school of Holland in the 50's of 20 centuries success.Since in 1954 at Dutch throw in the usage for the very first time.Because its a water fluid matter good, circulate the stability and manage convenience etc. technique characteristics, already at domestic and international and extensive application in live the dirty water to is dirty to manage aqueously with the industry[1].

Current application than oxidize extensively the ditch type include:The Pasveer oxidizes the ditch, the Carrousel oxidizes the ditch, Orbal oxidizes the ditch, the type of T oxidizes the ditch three ditch types oxidize the ditch, the type of DE oxidizes the ditch to turn to oxidize the ditch with the integral whole.These oxidize the ditch because of the difference of esse in construction with circulating, therefore each characteristics[2].This text will introduce construction, mechanism, existent problem and its latest developments that Carrousel oxidize ditches primarily.

2. The Carrousel oxidizes the construction of the ditch

The Carrousel oxidize the ditch to be researched to manufacture by Dutch DHV company development in 1967.Oxidize the last the company of DHV in foundation of the ditch in the original Carrousel to permited
