目首先使固化劑與淤泥接觸前就與水混合形成固化劑混合液，省去了常規工藝中灑干粉導致的配比不精確，固化劑干粉散布不均勻的問題，同時大大節約了固化劑的用量;

　　Firstly, the curing agent is mixed with water before contacting with sludge to form the curing agent mixture, which eliminates the problems of inaccurate proportion and uneven distribution of curing agent dry powder caused by spraying dry powder in the conventional process, and greatly saves the amount of curing agent;

　　其次，利用帶旋噴的固化動力頭的作業挖掘機在岸上可直接將固化劑混合液噴入河道現場的淤泥中，一方面，無需進行水上作業，另一方面，可以在河道現場直接進行淤泥的固化，無需將淤泥輸送上岸后再行處理，省時省力，固化效率高;再者，采用高壓旋噴的方式往河道淤泥中噴入加壓的固化劑混合液，在實現常規的固化劑與淤泥混合的同時，利用高壓旋噴對河道淤泥的切割作用，進一步提高了攪拌的效率，方便固化工藝的進行和完成。

　　Secondly, the working excavator with rotary jet curing power head can directly spray the curing agent mixture into the sludge on the river site on the shore. On the one hand, there is no need for water operation, on the other hand, the sludge can be solidified directly on the river site without sending the sludge ashore for treatment, which saves time and labor and has high curing efficiency; In addition, the pressurized curing agent mixture is sprayed into the river sludge by high-pressure rotary jet. While mixing the conventional curing agent with the sludge, the cutting effect of high-pressure rotary jet on the river sludge is used to further improve the mixing efficiency and facilitate the progress and completion of the curing process.
