It obtains mud to be fully cured, finally salvages by the mud after solidification, that is, complete the solidification of riverway sludge.
9. sullage solidifying method according to claim 8, it is characterized in that: in the step S2, riverway sludge inorganic agent
The 8%-12% that quality is mud quality is added.
