| titleOfInvention | Preparation method of sludge dehydrating agent |
| abstract | The invention discloses a preparation method of a sludge dehydrating agent, belonging to the field of environmental protection. The invention utilizes ferric chloride hexahydrate and sodium borohydride to prepare zero-valent iron nanoparticles, the oxidation reaction of adding zero-valent iron in sulfuric acid to convert the zero-valent iron into ferrous iron is realized through a two-electron transfer reaction, oxygen molecules are activated into hydrogen peroxide, and after the electrons are transferred to an iron oxide nuclear shell layer, the electrons are adsorbed on electrophilic oxygen molecules on the surface and captured, so that the sludge has preoxidation effect, and can be degraded into substances with smaller molecular weight, thereby being beneficial to combining water release and converting into free water, accelerating the release of water, simultaneously generating hydroxyl free radicals, decomposing the sludge, accelerating the dehydration process and shortening the dehydration time. The invention solves the problems that the existing sludge dehydrating agent has long dehydrating time, generates a large amount of gas accompanied with odor in the process and has low dehydrating effect. |
