“一体化废水处理设备”中的AO生物处理工艺采用推流式生物接触氧化池，它的处理效果优于完全混合式或二、三级串联完全混合式生物接触氧化池。并且它比活性废泥池体积小，对水质适应性强，耐冲击性能好，出水水质稳定，不会产生废泥膨胀。同时在生物接触氧化池中采用了新型弹性立体填料，它具有实际比表面积大，微生物挂膜、脱膜方便，在同样有机负荷条件下，比其它填料对有机物的去除率高，能提高空气中的氧在水中溶解度。
The Ao biological treatment process in the "integrated wastewater treatment equipment" adopts the push flow biological contact oxidation tank, and its treatment effect is better than that of the completely mixed or two or three-stage series connection biological contact oxidation tank. Moreover, it is smaller than the active sludge pond, has strong adaptability to water quality, good impact resistance, stable effluent water quality and no sludge expansion. At the same time, a new type of elastic solid filler is used in the biological contact oxidation tank. It has a large specific surface area, and it is convenient for microorganism to hang and remove the membrane. Under the same organic load condition, it has a higher removal rate of organic matter than other fillers, and it can improve the solubility of oxygen in air in water.
产废泥量少 90天排一次泥
Waste mud less than 90 days
“一体化废水处理设备”由于在AO生物处理工艺中采用了生物接触氧化池，其填料的体积负荷比较低，微生物处于自身氧化阶段，因此产泥量较少。此外，生物接触氧化池所产生废泥的含水率远远低于活性废泥池所产生废泥的含水率。因此，“一体化废水处理设备”所产生的废泥量较少，一般仅需90天左右排一次泥。
Because the "integrated wastewater treatment equipment" uses biological contact oxidation tank in Ao biological treatment process, the volume load of its filler is relatively low, and the microorganism is in its own oxidation stage, so the sludge production is less. In addition, the water content of the sludge produced by the biological contact oxidation tank is far lower than that produced by the active sludge tank. Therefore, the amount of waste sludge produced by the "integrated wastewater treatment equipment" is less, generally only about 90 days to discharge sludge.
