The river is the soul of the city and brings the spirit of the city. As the seasons change and the years go by, there are more and more impurities in the rivers, and river desilting is imperative. The river will affect the functions of flood control, drainage, irrigation and water supply if it is silted up. In order to restore the normal function of the river, river dredging and dredging projects are indispensable, among which sludge treatment is an important part of the river dredging process.
Usually the operation is to transport the river bottom sludge to the sludge curing station of the river dredging project by pipeline, or boat, after adjusting the PH value to a reasonable range, then add inorganic flocculants PAC and polyacrylamide to break the stability of the colloidal particles in the sludge, then neutralize its electrical properties by the amide group on the molecular chain of polyacrylamide to separate the sludge and water, and then press and dewater through the filter press again. Generally speaking, the dewatering equipment used are belt filter press, plate and frame filter press, etc. For river dredging projects, some sludge is treated with anionic and some with cationic, which agent should be selected according to the sludge and mud press equipment on site.
Among them, cationic polyacrylamide is more used in sludge dewatering, there are many models of cationic polyacrylamide, which model should be selected to be suitable? We can take the sludge water sample from the site and observe the effect of each cation with the same amount of addition, and select the appropriate model. The wider the range and the more models, the more suitable models can be selected.
