目首先使固化剂与淤泥接触前就与水混合形成固化剂混合液，省去了常规工艺中洒干粉导致的配比不精确，固化剂干粉散布不均匀的问题，同时大大节约了固化剂的用量;

　　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，利用带旋喷的固化动力头的作业挖掘机在岸上可直接将固化剂混合液喷入河道现场的淤泥中，一方面，无需进行水上作业，另一方面，可以在河道现场直接进行淤泥的固化，无需将淤泥输送上岸后再行处理，省时省力，固化效率高;再者，采用高压旋喷的方式往河道淤泥中喷入加压的固化剂混合液，在实现常规的固化剂与淤泥混合的同时，利用高压旋喷对河道淤泥的切割作用，进一步提高了搅拌的效率，方便固化工艺的进行和完成。

　　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.
