5.2 Carrousel 3000 system
    Carrousel 3000 systems are in the Carrousel 2000 systems are ex-to plus a living creature the choice the area.That living creature choice area is a craft to make use of high organism carries to sieve germ grow, repress silk form germ increase, increase each pollutant do away with the rate, afterward principle together Carrousel 2000 syste m.
Carrousel 3000 system of bigger increases to express at:An is to increased the pond deep, can amount to 7.5"'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;( can amount to 7 '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;Three is to used the advanced spirit controller QUTE.( it adopt the much aer kind of changing the deal control mode)f our is to adopt the integral whole turn the design, starting from the center, Including below wreath form consecuuon craft unu.eoter the well of waterwiththecent watermachine thatused for the liveand dirty mire in reflux;Difference from four-part the choice pond that cent constitute with !X oxygen pond.This outside is a Carrousel to have three spirit machine with a prepare versa nitric turn the pond 2000 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, anti-pounds at the burthen ability with circulate to manage the convenience etc. the advantage, having got the extensive application.But because of technological development with social advance, that craft is necessarily will exaltation getting further.The 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 crtcn.uke 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 crtcn.scr 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 become 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 technique.Function that increases form machine, underwater propeller, reduce to maintain the workload; Making use of DO, etc. of ORP many targets supervises and control the technique and changes the technique of is from now on the carrouseloxidizes ditchsciencecirculatenecessarilyfromitroad.
4 Increasing the Carrousel oxidizes the ditch resistant to cold and bear toxicity can, reduce to cover the area to build the price with the engineering.Theoretical application, deep pond in water power term with the research of the craft function is to lowers the engineering builds the price and increases resistant to cold bear the toxicity can wait to provide the possible direction.
