Abstract

The invention relates to the field of kitchen waste grease wastewater recycling, and particularly discloses a kitchen waste grease wastewater treatment system and a treatment method thereof. The kitchen waste grease wastewater treatment system comprises a pretreatment mechanism, a sedimentation mechanism, a filtering mechanism and a purification mechanism; the pretreatment mechanism comprises an oil separation tank, wherein the oil separation tank is communicated with the sedimentation mechanism; the sedimentation mechanism comprises a sedimentation tank, wherein the sedimentation tank is communicated with the oil separation tank and the filtering mechanism; the filtering mechanism comprises a first filter and a second filter, wherein the first filter is communicated with the sedimentation tank and the second filter, and the second filter is communicated with the purification mechanism; and the purification mechanism comprises a first centrifugal machine and an aeration tank, wherein the first centrifugal machine is communicated with the second filter and the aeration tank. According to the kitchen waste grease wastewater treatment system, wastewater and garbage in kitchen garbage can be separated, and the effect of improving kitchen wastewater purification is achieved.

Description

technical field [0001] The present application relates to the field of recycling and utilization of waste kitchen grease and wastewater, more specifically, it relates to a treatment system and method for kitchen waste grease and wastewater. Background technique [0002] With the continuous improvement of people's living standards, the catering industry is growing stronger and stronger, followed by a large amount of food waste. Food waste is an important part of domestic waste. It has a huge output and rich organic matter content. If it can be used reasonably, it will be a valuable energy source. [0003] At present, landfill, composting and feed technology are generally used to deal with kitchen waste at home and abroad. However, there are both solid components and a large amount of liquid components in food waste. The liquid components include oil and waste water. After people separate the oil and waste water, they can use the oil as raw material to produce biodiesel. The ...
