Abstract
The invention belongs to the field of organic matter dewatering treatment, particularly relating to a dewatering preparation method for high-purity organic matters. Firstly, water absorbent is adopted for absorbing the water of a target organic matter so as to purify the target organic matter; and a microfiltration film or ultrafiltration film is adopted for separating the water absorbent after absorbing the water and the purified target organic matter so as to obtain the high-purity organic matter. The dewatering preparation method for the high-purity organic matters solves the problem that the current organic matters with higher purity are diffuclt to meet high-purity requirement during dewatering process, in particular to the problem of overhigh energy consumption of the current dewatering method. Meanwhile, the product quality is improved; and the purity of the target organic matter can be stably improved to 99.0-99.9999 percent; meanwhile, the water absorbent can be recycled and used and no pollution wastes are discharged; therefore, not only is the material and energy consumption reduced, but also the environment is protected; meanwhile, the production cost is reduced and the economic benefit is very obvious; and the technical progress on relevant industries like fuel ethanol and the base materials of the Internet of things can be effectively promoted. The dewatering preparation method for the high-purity organic matters has excellent social benefits.
