Embodiment

[0027] Attached below Figure 1-3 Embodiments of the present invention are described in detail:

[0028] Catering waste degreasing treatment method, the food waste is first filtered through the coarse grid and then enters the pretreatment pool, the water-containing food waste is coarsely filtered through the coarse grid, and the large-diameter solid matter in the garbage is removed, and then the pH value is adjusted to 3- 5. Add a certain amount of compound flocculant, first stir rapidly at 400r / min for 3min, then adjust the stirring speed to 60r / min, stir slowly for 20min, let stand for a period of 30min and then settle and stratify.

[0029] Such as figure 1As shown, the upper liquid enters the buffer pool through the waste water pipeline, where it is collected and stabilized, and the outlet of the buffer pool 1 is connected to the fine grid 2 through the waste water pipeline, where the small-diameter solid matter in the food waste is removed, and the fine grid The outlet ...

Abstract

The invention discloses a food waste oil removing treatment method. Water-containing food waste is sequentially subjected to flocculation pretreatment, a buffer tank, a micro-bubble gas oil spill absorption device, an oil catalysis, re-solution and absorption reactor, a pH regulation tank, a primary sedimentation tank, an organic rhodium catalytic-reaction tank, a biological denitrification tank, a secondary sedimentation tank and a clear water tank. The method creatively utilizes the oil molecule catalysis action of a pi-allyl nickel compound, when the oil in wastewater is adsorbed by modified diatomite and is at the temperature of 200-250 DEG C, the C-H bonds in the oil molecules can transiently break under the catalysis action of the pi-allyl nickel compound and are rapidly recombined into C-C bonds or C-H bonds, the C-H bonds break again, while the C-C bonds do not break again due to the limited catalysis action of the pi-allyl nickel compound. Therefore, oil molecules shorter in carbon chain can be gradually synthesized into heavy oil molecules longer in carbon chain.

Description

technical field [0001] The invention relates to a method for degreasing and treating food waste, which belongs to the field of kitchen waste water treatment in environmental protection. Background technique [0002] Among domestic sewage, catering wastewater is one of the main water bodies. Numerous restaurants, canteens, food processing enterprises and residents will discharge a large amount of sewage in their daily life, which contains a large amount of animal and vegetable oils. If it is not treated directly, it will cause blockage of pipelines, turbidity and corruption of water bodies, and breeding of diseases. source. [0003] At present, the existing catering waste wastewater degreasing methods include the following four. [0004] (1) Physical methods mainly include filtration separation method and air flotation separation method, but they are only suitable for separating oil products with large particles in wastewater. The treatment efficiency is 60-80%, and the oil...
