Foreword Oxidize 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 graduateschool of Holland in the 5039。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。 [6] Dudley, J.
