totakethe greaseoflarge quantityinthewater, handling system can39。 t pletely and availably its obviation, parts of greases enriches to gather in in the dirty mire, through turn to brush the oxygen agitation, creation large quantity foam。 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 anism 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 the oil over the high waste water and other poisonous waste water of into[llJ. Float the problem on the dirty mire When contain in the waste water the oil measures big, whole system mire quality bee light, can39。 t like to control very much in operate process its at two sink the pond stop over time, resulting in the anoxia easily, producing the corrupt and dirty mire ascend to float。 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。 Moreover, contain the oil in the waste water? Take place thedirtymire ascendafterfloating should pauseenter water, broke off or dirty mire in clearance, judge the clear reason, adjust the dirty mire sinks to decline the sex bad, can throw to add of oagulate or sloth materials, the improvement precipitates the sex。 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。 1f discover the dirty mire is corrupt, should enlargement tolerance, the clearance accumulates the mire, and try the ameliorative pond internal water dint term!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。 530 oxidize the ditch water the deep(~ ms) paring, turn to brush occupied the deep 1 / 1 0~ in water 1/12, turned the dish to also occupy the 1/639。 only 1/7, therefore result in to oxidize the ditch upper part current velocity bigger{ roughly 39。 ms, even larger}, but the bottom current velocity is very small( especially at the water is deep 2/3 or 3/4 below, mix with the liquid has no current velocity almost), causing ditch bottom large quantity accumulate the mire( sometimes accumulate the mire thickness amount to a ms), the valid capacity that reduced to oxidize the ditch consumedly, lowered to handle result, affected a water fluid matter[13]. Moreover, pass in the spirit on board swim to establish the underwater push machine can also turn to the spirit of the liquid of admixture that brush the bottom low speed area circulates to flow to rise positive push function, from but the solution oxidizes the problem that low and dirty mire。
