The Carrousel oxidizes the ditch divideds by the phosphorus takes off the nitrogenous influence factor. Affecting the Carrousel oxidizes the ditch divideds by the phosphoric factor is dirty mire, nitrate density and quality densities research expresses, being total and dirty mire as 11% that a hour biggest phosphorus 4% with deal is its fuck dirty mire deal within live and dirty mire, keep for the the germ physical endowment measures, but when dirty mire over 15 d hour dirty mire the Inside is biggesttocontain theobviousdescentindealIn phosphorus,canning not reach the biggest divideding by the result of phosphorus on the , prolong persistently the dirty mire (for example 20ds,25ds,30ds) is to have no necessary, proper choose to use within the scope of 8~ 15 the same time, high nitrate density with low quality density disadvantage in divided by the process of phosphorus . 4. The Carrousel oxidizes problem and solution methods of the ditch esse. Though the Carrousel oxidizes the ditch has a water fluid matter good, the antipounds at the burthen ability strong, divided by the phosphorus take off the nitrogen efficiency. But, in physically of movement process, still exstts a series of problem. Dirty mire inflation problem When discard the aquatic carbohydrate more, the N, P contains the unbalance of deal, the pH value is low, oxidizing the dirty mire in inside in ditch carries high, fuse the oxygen density the shortage, line up the mire not etc. causes easily dirty mire ingerm in form in silk inflatlon。 in 1954 at Dutch throw in the usage for the velY first nme.secause 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 aquecustv with the industy[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 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 pany development in the last the panyofDHVinfou ndationoftheditchin theoriginal Carrousel to permited specially the pany EIMCO to invent again with its patent in the United States Carrousel 2020 syste
