所谓抛泥处理就是将大量的废弃淤泥运输至离水体距离较近的特定抛置区并倾卸，然后经过水体的不停降解和交替作用，而不会对水体环境造成致命性破坏，从而降低淤泥对水体的污染程度。这是长期以来处理淤泥最常用的方法。
The so-called sludge disposal is to transport a large amount of waste sludge to a specific disposal area close to the water body and dump it, and then through the continuous degradation and alternating action of the water body, without fatal damage to the water environment, so as to reduce the pollution degree of sludge to the water body. This is the most commonly used method for sludge treatment for a long time.
但此方法的缺点就是随着淤泥抛弃量的剧增，既占用了宝贵的土地资源，对距离较远的地方又产生了很大的运输费用，淤泥中的有害物质又对环境产生了很大危害。
However, the disadvantage of this method is that with the sharp increase of sludge abandonment, it not only occupies valuable land resources, but also produces great transportation costs for distant places, and the harmful substances in sludge do great harm to the environment.
