How to dispose of the oil in the grease trap of food wastewater

Tianjin Bolifeng grease trap for oil removal, organic matter can be removed by AO method. Process, if the scale is large, the sewage will be passed into the regulating tank first, and the scale is small, and it can be used through the grid, then the grease trap, and the biochemical treatment tank, if the requirements are high, then through the secondary treatment, and then discharged.

There is a special food waste treatment method for catering waste oil, which must not be purchased by people and turned into gutter oil.

The catering service business shall be responsible for the harmless treatment of the kitchen waste oil of the restaurant. Catering service businesses must arrange full-time (part-time) personnel to be responsible for the daily collection, storage, registration, and management of flow records of kitchen waste oil, and classify and place kitchen waste and waste oil, so that Nissan Nissan is clear.

There are three main aspects of food waste disposal.

1. Domestic waste landfill landfill. This is the most traditional way, before the implementation of garbage sorting in the early days, domestic garbage and food waste were mixed together, and they were basically landfilled.

2. Biodegradation. In some places, biodegradable bacteria have been used to biodegrade food waste, and about 10% of the residue will be degraded and then landfilled and incinerated.

3. Ecological disposal and composting. Eat food waste to raise cockroaches, black soldier flies, earthworms and other insects, and use insects to eat the garbage, and the excrement of insects is a good flower fertilizer. Foods like black soldier flies and earthworms can also be made into protein powder at different stages for farming feed.

Composting is the fermentation and composting of food waste for agriculture.

Catering service businesses should review the qualifications of the kitchen waste oil collection and transportation unit (the kitchen waste oil collection and transportation unit shall have the corresponding qualifications and obtain the relevant license or record), sign a collection and transportation contract with it, and prohibit the kitchen waste oil from being handed over to the kitchen waste oil collection and transportation and disposal unit or individual without the permission or filing of the relevant departments.

1. Floating method: It is mainly used for the advanced treatment of grease trap effluent to remove fine oil beads and emulsified oil. 2. Cloth gas floating method:

It is mainly used to break the bubbles mixed into the water with the help of mechanical shear force, or disperse the air into fine bubbles before entering the wastewater, and carry out the air-water mixing and floating. 3. Dissolved gas floatation method: It is to precipitate gas from wastewater containing supersaturated air to produce bubbles to achieve floating.

4. Electrolytic floatation method: the electrolytic redox effect in oily wastewater is used to purify oily wastewater by using the electrolytic redox effect and the floating effect of the tiny bubbles generated on the electrode.

At present, it is mainly to make biodiesel, but also to make soap, soap and the like.

If you know and have time, you can clean it up yourself, if you don't have time and don't want to do it, find a professional cleaning company, after all, greasy things are more difficult to clean, and you need to clean up regularly, and the professional cleaning team can regularly check and clean up, which is more trouble-free and worry-free.

The method of dissolving solid waste in a grease trap depends on the specific composition of the waste. Generally speaking, wastes can be divided into two types, organic and inorganic, and the corresponding chemicals are also different.

Waste dissolution treatment of organic matter:

1.Organic wastes are mostly oily substances, and emulsifiers, such as soaps, colloidal polymers, etc., can be added to the grease trap to improve the solubility and stability of the waste, promote the suspension and sedimentation of eggplant, and facilitate removal.

2.The use of oxidants to treat oily waste, such as hydrogen peroxide, ozone, etc., can decompose the organic substances in the waste into small molecular structures such as CO2 and water, so as to reduce the concentration of pollutants and make the treated materials better treated.

Waste dissolution treatment of inorganic substances:

1.The simple treatment of inorganic pollutants can be done by acid-base neutralization, which reacts the inorganic substances in the waste with acids or alkalis to form new compound substances, and dissolves them in water hollowing.

2.Activated oxidation methods, such as ozone, chlorine in ** state, chloric acid oxidant, potassium persulfate, etc., can oxidize inorganic substances that are difficult to treat, making them more chemically stable substances, which are easy to treat after sedimentation and filtration.

It should be noted that the grease trap is a kind of environmental protection equipment, and before the waste is dissolved, it is necessary to understand the nature and characteristics of the pollution source, adjust the temperature, pH value and add chemicals, etc., in order to achieve better chemical reaction and precipitation effect. At the same time, for the sake of safety and environmental considerations, it is necessary to comply with relevant regulations and standards, and strictly abide by production standard operating procedures and operating regulations. It is advisable to consult a professional for guidance and advice before use.
