Novel sludge-water separating agent

The invention belongs to the technical field of environmental protection, particularly relates to a novel sludge-water separating agent, and provides the following scheme aiming at the problem of single effect of the sludge-water separating agent: the novel sludge-water separating agent comprises an organic polymeric flocculant, which is prepared from the following raw materials: hexadecyl trimethyl ammonium bromide (HTAB, an etherifying agent), potato residues, 0.2 mol/L NaOH and absolute ethyl alcohol, wherein the preparation method of the organic polymeric flocculant comprises the following steps: S1, adding 100 g of potato residues into 500 ml of NaOH solution with a mass concentration of 0.2 mol/L, and alkalizing at 50 DEG C for 1 hour. According to the invention, the mud-water separating agent only needs to be added into the sludge, so that soil molecules collide, attract and react with one another while free water in the soil is adsorbed out to convert the free water into crystal water, and the soil mo
