J.。Difference from fourpart the choice pond that cent constitute with !X oxygen outside is a Carrousel to have three spirit machine with a prepare versa nitric turn the pond 2020 system.( such as figure 2 show)Five is tube line that the design that the circular integral whole turn to make oxidize the ditch do not need additionally, can immediately realize dirty mire in reflux allotment in different craft unit[I7J. 6. Conclusion The Carrousel oxidizes the ditch because of having the good a phosphorus takes off the nitrogen ability, antipounds at the burthen ability with circulate to manage the convenience etc. the advantage, having got the extensive because of technological development with social advance, that craft is necessarily will exaltation getting author thinks:The carrousel oxidizes the future research direction of the ditch will now of main below several aspects. 1 Combination living creature method, research with develop the living creature model carrousel oxidize the this can not only increases the microorganism gross of the unit reactor measures, from but increases the organism carries, but also living creature oneself the inside that have places the AI the system of 0 enhances to take off the nitrogen result[IBl. 2 Increases continuously the Carrousel oxidize the microbial activity in Inside in example throw to add the EM in oxidize ditch with single mind the germ grow, throws in that the salt of Iron make the microorganism tame the live char in iron, devotion in living creature to bee the torrnation to strengthen the germ gum regiment and increases to bear the toxicity pound at etc.. 3 Increasing the Carrousel oxidizes the ditch equtpments function with supervise and control the that increases form machine, underwater propeller, reduce to maintain the workload。C )Two is the liquid of admixture that spirit equipments that skillful design, the form machine descends to install to lead to flow ,the anoxia of take out, adopt the underwater propeller solution current velocity problem。8 ms, united at heart circle type, the pond wall uses totally, reducing to cover the area, lowering to build the price to increases to bear the low temperature ability at the same time。 only 1/7, therefore result in to oxidize the ditch upper part current velocity bigger{ roughly 39。:. Current velocity is not all and the dirty mire sinks to accumulate the problem In Carrousel oxidize ditch, for acquiring its special admixture with handles result, mix with liquid must with certain current velocity is in ditch circulate generally, the lowest current velocity should should attain for an average current velocity for, doing not take place sinking acccmutetmq ~ msl spirit equipments that oxidize the ditch is general to turn to brush for the spirit of to turn the dish with the spirit of , turning to brush of immerse to have no depth for 25 0 ~300 mms, turn the dish immerse to have no depth for 48039。Suchas enterthe watercarries big let upintothe water measures or the enlargement reflux as the dirty mire grain small lower the spirit machine turn discovers versanitricturning,shouldletup thetolerance,enlarge the reflux or row the mire measures。When spirit time over long, take place in pond the high degree nitric turn the function, making nitrate density high, at two sink the versa nitric in easy occurrence in pond turn the function, creation nitrogen spirit, make dirty mire ascend f1oat。The mire is partial to long, the dirty mire is aging, and also easy creation topourthewaterordivided bywiththesurfacetheof do away with the foam, in mon use divided by the an organism oil, kerosene, the oil of stncon, throw deal as ~ mgsl to increase dirty mire in pond in spirit in density or adequacies let up the tolerance of ,also can control the foam creation contain the live materia! in surface in the waste water more, separate with the foam easily and in advance method or other methods do away can consider to increase to establish a set of dlvideding by the oil device enhance most importantly the headwaters manage, reducing to contain th
