Embodiment 1

[0026] A kind of environmental treatment method of waste oil, comprises the steps:

[0027] a) Pretreatment of the collected waste oil: put the collected waste oil on the filter screen, the mesh of the filter screen is 10-20 mesh, spray it with 75°C water to collect the filtrate, put the filtrate on the Put it into a heating container with a liquid outlet and a material outlet higher than the liquid outlet and heat it for 2 hours while stirring. After standing for 30 minutes, first flow the water layer out from the liquid outlet to obtain a turbid liquid, and then discharge the upper layer of oil from the outlet. , and then discharge the lower layer of oil from the liquid outlet;

[0028] b) Treatment of auxiliary materials: crush the straw with a pulverizer to obtain straw powder, take straw powder and plant ash at a weight ratio of 20:1 to prepare auxiliary materials;

[0029] c) Treat the turbid liquid and lower layer oil: take auxiliary materials, turbid liquid and lower ...

Embodiment 2

[0032] A kind of environmental treatment method of waste oil, comprises the steps:

[0033] a) Pretreatment of the collected waste oil: put the collected waste oil on the filter screen, spray it with water at 60°C to collect the filtrate, put the filtrate into a filter with a liquid outlet and above the liquid outlet Heating the heating container at the discharge port for 3 hours while stirring. The heating temperature of the heating container is 70°C. After standing for 45 minutes, the water layer flows out from the liquid discharge port to obtain a turbid liquid, and then the upper layer oil is discharged from the discharge port, and then The lower layer oil is discharged from the liquid outlet, wherein the distance between the liquid outlet and the discharge port is 10 cm. ;

[0034] b) Treatment of auxiliary materials: crush the straw with a pulverizer to obtain straw powder, the straw powder is 40-60 mesh, take straw powder and plant ash at a weight ratio of 10:1 to prep...

Embodiment 3

[0039] A kind of environmental treatment method of waste oil, comprises the steps:

[0040] a) Pretreatment of the collected waste oil: put the collected waste oil on the filter screen, spray it with 90°C water to collect the filtrate, put the filtrate into the filter with a liquid outlet and higher than the liquid outlet Heating in the heating container at the discharge port for 1 hour while stirring. The heating temperature of the heating container is 90°C. After standing for 60 minutes, the water layer flows out from the liquid discharge port to obtain a turbid liquid, and then the upper layer oil is discharged from the discharge port, and then The lower layer oil is discharged from the liquid outlet, wherein the distance between the liquid outlet and the discharge port is 20cm. ;

[0041] b) Treatment of auxiliary materials: crush the straw with a pulverizer to obtain straw powder, the straw powder is 40-60 mesh, take straw powder and plant ash at a weight ratio of 15:1 t...

Abstract

The invention discloses an environmentally-friendly treatment method for gutter oil, and the environmentally-friendly treatment method comprises the following steps: a) pretreatment of gutter oil, tobe more specific, putting the collected gutter oil on a the filter screen, spraying a collected filtered matter with hot water, heating the collected filtered matter in a heating container, and layering the collected filtered matter after standing to obtain a turbid liquid, upper oil and underlying oil; b) treatment of an auxiliary material, to be more specific, taking straw powder and plant ash according to a weight ratio of 10-20:1 to prepare the auxiliary material; c) treatment of the turbid liquid and the underlying oil, to be more specific, taking the auxiliary material, the turbid liquidand the underlying oil into a fermentation tank, then adding methane bacteria to ferment; and d) continued fermentation, to be more specific, after the end of the fermentation, discharging the liquidin the fermentation tank, dividing the excess turbid liquid into 2-5 parts, adding 1 part of the turbid liquid, the methane bacteria and the auxiliary material to the fermentation tank for post-fermentation, after the end of the post-fermentation, discharging the liquid in the fermentation tank, and repeating the above steps. The method is environmentally friendly in treatment process, enhancesthe utilization rate of the gutter oil, and has simple operation and complete fermentation process.

Description

technical field [0001] The invention relates to the technical field of waste oil treatment, in particular to an environmentally friendly treatment method for waste oil. Background technique [0002] Waste oil generally refers to all kinds of low-quality oils that exist in daily life, such as recycled cooking oil, repeatedly used frying oil, etc. The largest source of waste oil is the grease trap in the sewer of large hotels in cities. Long-term consumption may cause cancer, which is extremely harmful to the human body. [0003] In the process of refining "gutter oil", animal and vegetable oils undergo a series of chemical changes such as rancidity, oxidation and decomposition after being polluted, and produce substances that are highly toxic to the human body; arsenic is one of them. Huge "gutter oil" can cause symptoms such as indigestion, headache, dizziness, insomnia, fatigue, and discomfort in the liver area. [0004] At present, the disposal and reuse of waste oil in...
