An interface is established between the surface of the blanket of settling sludge and clarified liquid above . 在沉降污泥絮状悬浮层的表面与其上面的澄清液之间形成一个界面。
The trickling filter and activated sludge efficiencies cited required primary sedimentation and effluent circulation . 列举的生物滤池与活性淤泥法的效率就需要初次沉淀和回流。
The sludge is passed under a vacuum pump and allows the water to pass through a discharge or recirculation drain . 用真空泵除去污泥的固体含量而该泥水则经排水渠或回流渠排出。
Sugar-factory lime sludge had a more favorable influence in improving the structure of acid soils than limestone . 糖厂的石灰沉渣，在改良酸性土结构上，要比石灰石粉有更良好的影响。
Iron and aluminum compounds are generally regarded as undesirable because of sludge formation in the product acid . 铁化合物和铝化合物通常认为是不好的，因为它们在产品酸中生成淤渣。
The air swept out the potentially damaging substances before they had a chance to form sludge or corrode parts . 在他们有机会形成油泥或腐蚀部件之前，流动的空气先清除了这些有潜在危险的物质。
In the case of natural fibers biological degradation will occur when the fiber is retained with the sludge in the treatment plant . 就天然纤维而论，当纤维附在处理站的污泥上时，可能发生生物降解。
