But this wood is very hard to deal with them, it is the fruit itself, contain too much sugar and fruit gum, in order to make it into finished products, the non-deformation, non-cracking, to go through up to 80 deal with multi-channel processes, and Add some of the necessary chemical raw materials, processing cycle time of up to five and a half months.

可是这种木材处理起来非常的难，它本身是果树，含有过高的糖分和果树胶，为了使它做成成品后，不变形，不开裂，要经过多达80多道工序的处理，而且添加一些必要的化学原料，处理周期长达五个半月的时间。

After different sediments ignitions, S was 1.64~2.25 times of that of raw sediment, higher obviously than the sediments without ignition. The aerating pretreatments of sediment and water caused the transformation of bioavailable form to nonavailable form. The bioavailable phosphorus decreased 7.02% and 0.23% respectively compared with that before pretreatment, but the bioavailable phosphorus of the blank test sediment increased 4.85%.

不同底泥灼烧后，最大吸附量为天然底泥的1.64~2.25倍，且明显高于未灼烧底泥对底泥曝气与对水曝气预处理使易被生物利用态磷向难被生物利用态磷转化，易被生物利用态磷较预处理前分别减少了7.02%和0.23%，而空白试验底泥的易被生物利用态磷则增加了4.85%。

This environmentally friendly pretreatment process was under mild condition, and, compared with conventional methods, it can shorten oxidation time. The study provides a practical and effective pretreatment method for the exploitation of similar high-sulfur and high-arsenic RGC.
