Description
Technical Field
The utility model relates to a mechanical device especially relates to an oil-water separator.
Background
With the increase of national economy, the catering industry develops rapidly, and the amount of waste water discharged is larger and larger. The waste water contains animal and vegetable oil with high concentration and a large amount of solid suspended matters, so that the waste water becomes an important water pollution source, and the treatment of oily waste water in catering industry can not only protect the ecological environment, but also reduce the burden of urban sewage treatment stations, thereby having obvious environmental benefit and economic benefit. The oily wastewater in the catering industry has high pollution content, and the main pollutants are animal and vegetable oil, chemical oxygen consumption, suspended matters and the like. At present, the application of the detergent in the catering industry leads oil to float in water in an emulsified state, thereby greatly increasing the value of chemical oxygen consumption in water, which generally reaches thousands of mg/L; secondly, the oil and the detergent have small specific gravity, so that the oil and the detergent are bonded with the suspended matters of the wastewater and are not easy to settle; in addition, the situation that the sewer is blocked to discharge oily water is very common. Therefore, animal and vegetable oil is a key pollutant, and the reduction of the oil content in the oily wastewater in the catering industry has direct influence on the reduction of the chemical oxygen demand and suspended matters. The use of the detergent makes the oil in the oily wastewater in the catering industry emulsified, the oil-water separation is difficult to be carried out in a common oil separation tank, the emulsified oil needs to be demulsified, and meanwhile, the animal and vegetable oil is white paste at normal temperature, so that the pipeline is easy to block during the oil-water separation, and the wastewater treatment is difficult. The oily wastewater in the catering industry has the following hazards: worsen water quality and harm aquatic resources; the health of human body is harmed; pollute the atmosphere, influence crops production, natural landscape, clean natural water source. Because the catering wastewater has complex components and high organic matter content, if the wastewater is discharged into a municipal pipe network without treatment, the pipe network is easy to block and the treatment pressure of a sewage treatment plant is increased.
Therefore, the treatment of the restaurant wastewater reaching the standard has important practical significance.
