【正文】 The value of pH over low, can throw to add the lime regulate。If the dirty mire carries high, can increase MLSS, to adjust the burthen, necessity the hour can stop into the water, stuffy a period of time。At the same time, the ammonia were too oxidized nitrate with second nitrate, this time, mix with the liquid be placed in the oxygen the spirit machine downstream, after water current be bee by the swift flow appearance of the spirit District of even flow the appearance, the water current maintains in the minimum current velocity, guaranteeing the live and dirty mire be placed in the floats the appearance.( average current velocity ms/ s)Oxidize microbially the process consumed to fuse the oxygen in the water, until the value of DO declines for zero, mixing with the liquid report the anoxia nitric that turn the function through anoxia area, mix with the liquid enter to have the oxygen area, pleting once system inside, the BOD declines the solution is a continuous process, the nitric turns the function to turn with the versa nitric the function take place in same of structural restrict, this kind of oxidize the ditch although can then valid whereabouts BOD, divided by the phosphorus take off the nitrogenous ability limited[7].For the sake of the acquisition better divided by the phosphorus take off the nitrogenous result, Carrousel 2000 systems increased a oxygen District before mon Carrousel oxidize ditch with the unique oxygen area.( call again that the versa nitric in front turns the area)The dirty mire in all refluxes enters the anaerobic District with 1030% dirty water, can under the anoxia with 1030% carbon source term plete remaining of dirty mire in reflux inside nitric acid nitrogen to versa nitric to turn, creates for the unique oxygen pond of hereafter unique oxygen the same time, anaerobic District inside of concurrently the sex germs convert the dissolubility BOD VFA, the germ acquire the VFA its assimilation PHB, the energy source needed solves in the phosphoric water and cause phosphatic anaerobic District a water enters the inner part installs the unique oxygen area that have the mixer, the socalled unique oxygen is a pond inside to mix with liquid since have no the numerator oxygen, also have no the pound oxygen( nitric acid root), the here unique oxygen environment is next,7090% dirty water can provide the enough carbon source, can make the germ of released the phosphorus unique oxygen area connects behind the mon Carrousel oxidizes the ditch system, further pleting to do away with the BOD and take off the nitrogen with divided by the phosphorus .Finally, mix with the liquid transfer the dirty mire inside in oxidize ditch enrich oxygen area eject, while enriching the oxygen environment germ surfeit, phosphorus from the water, ejecting the system with the dirty mire in this, in Carrousel 2000 systems, than pleted to do away with the BOD, COD with take off at the same time goodly the nitrogen divided by the phosphorus .Synthesizing and dirty water in the river City , long sand City decontamination center[s of the dirty the factory of water in the first in Kunming of adoption that crafts handles the movement result of the factory therefore:Through Carrousel 2000 system after handling, the BOD, COD, SS does away with the rate to all e to a 90% above, the TN does away with the rate es to a 80%, the TP does away with the rate to also e to a 90%. 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 biggest to contain the obvious descent in deal in 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 .Affecting the Carrousel oxidizes the ditch takes off the nitrogenous and main factor is DO, nitrate density and carbon source research expresses, oxidizing the ditch inside exsits deliquescence oxygen density steps degree namely the good oxygen area DO attains 3~ mgs/ L, the anoxia area DO attains 0~ mgs/ L is a prior condition to take place nitric turn reaction and versa nitrics turn the the same time, ample carbon source and higher C/ the N ratio benefits to take off to plete nitrogenously[7].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 anti pounds at the burthen ability strong, divided by the phosphorus take off the nitrogen efficiency. But, in physically of movement process, still exsits a series of problem. Dirty mire inflation problemWhen 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 in germ in form in silk inflation。techniques1. ForewordOxidize the ditch( oxidation ditch) again a continuous circulation spirit pond( Continuous loop reactor), is a live and dirty mire method a kind of to the dirty water in ditch handles the craft be researched to manufacture by the hygiene engineering graduate school of Holland in the 5039。 nitrogen and phosphor removal。參考文獻(xiàn)　　1 王文遠(yuǎn) 污水截流工程截流倍數(shù)選擇的研究，給水排水，1997，10　　2 顏秀勤 奧貝爾氧化溝的工程應(yīng)用性能研究，中國給水排水，1999，7　　3 周 雹 中、小型城市污水處理廠的優(yōu)選工藝，中國給水排水，2000，10
