Abstract

In the course of engineering construction, a lot of abandoned mud is produced. How to properly handle these mud has received extensive attention. In this paper, the application of absorbent resin in waste mud treatment is studied by series of experiments. Compared with the common flocculants, the flocculation effect of absorbent resin is better, and the separation speed of waste mud solid liquid can be accelerated obviously. The water absorption rate of absorbent resin in the mud reaches 46.33 g/g, which can be incorporated into the mud to greatly reduce the water content and fluidity of the mud within 30 min, so that it can be changed from a flowing state to a plastic state, and the waste mud can be rapidly solidified. The results show that the absorbent resin has a good effect on the treatment of waste mud, and the feasibility of the treatment of waste mud is proved.
