At present, the "garbage besieged city" has become a roadblock affecting the current urban development, and the food waste treatment is also recognized as the key link of the current garbage treatment and disposal, because the food waste is basically in the state of disordered collection, transportation and disposal. Some kitchen waste is recovered by illegal traders and extracted into the so-called "waste oil" or directly fed to pigs into "swill pigs", and some of them are randomly dumped or mixed into domestic garbage. In order to put an end to the harm of gutter oil on people's health, effective measures must be taken to collect kitchen waste and make use of it as resources, so as to prevent "waste oil" from returning to the public table from the source.
Based on the technical advantages of military enterprises and the characteristics of food waste materials, HAI SHEN MACHINERY&ELECTRIC GENERAL WORKS (XIANGSHAN) has developed a domestic advanced level lws580ed centrifuge for the three-phase separation of food waste, and adopts the "three-phase separation" method The three-phase separation of kitchen waste has been successfully carried out in Xiamen Rui science and technology renewable energy Co., Ltd. After separation, the oil phase is used to extract industrial diesel oil. Part of the separated liquid phase is pumped into the slurry mixer for mixing, and part of the liquid phase is pumped into the slurry mixing buffer tank for slurry mixing. The residue phase is used for biogas production by anaerobic fermentation Gas and so on, truly realized the harmless treatment of kitchen waste.
