AB法不设初沉池，新鲜污水及SS直接进入A段，改善了污泥沉降性能，并可以从进水中得到微生物的补充，以维持反应器污泥浓度，生物相丰富，有大量固着型钟虫。

However, from the view of the structure and shape of the Orbal oxidation ditch, the round or ellipse tri-ditch type may be difficult to plane layout for the engineering with narrow land locations; the independent sedimentation tank occupies relatively large area of land; central island counts some areas which enlarges inefficient land demand; and the backflow of sludge and nitrified water from the sedimentation tank relies on dynamic system, which increase the cost of construction and operation.

但就奥贝尔氧化沟的工艺构型来看，三沟道的圆形或椭圆形沟型对于狭长的工程选址地来说，平面布置相对困难；而且奥贝尔氧化沟需要独立的二沉池，占地较大；中心岛消耗一定的面积，增加了无效占地；另外，二沉池的污泥回流依靠动力回流，增加了基建和运行费用。

The main reasons were that the algae and organism in the water decreased the ability of removing pollutants by coagulations, the algae which grown again in the open sedimentation tank weakened the removal effect of algae by coagulation; because of the accumulation of algae and algae toxin in the filtration tank, the concentration of algae toxin in the effluent increased; by the function of fluid chlorine, the algae and organisms after the filtration will release microalgae toxin and produce a lot of byproduct such as microalgae toxin, sobomyl and so on, meanwhile, the chlorination produce considerable halide and halo-acetic acid and other disinfection byproduct.

主要表现在藻类和溶解性有机物的存在降低了混凝去除污染物的能力；藻类在露天平流沉淀池中再生长，抵消了混凝除藻效果；藻类和藻毒素在滤池中积累，导致滤后藻毒素升高；穿透滤池的藻类和有机物在液氯作用下，释放微囊藻毒素、土臭素和二甲基异冰片等胞内物质，同时生成数量可观的卤代烃和卤乙酸等消毒副产物。
