What should be paid attention to in the separation of oil, water and residue of waste oil

In the process of oil-water separation of waste cooking oil, the following key points need to be paid attention to to ensure the separation effect and environmental protection: 1. Equipment selection: Choose a suitable oil-water separator. There are two main types of oil-water separators on the market: physical separation and chemical separation. Physical separators usually include gravity separation, centrifugal separation, etc., while chemical separation involves adding specific chemical reagents to promote oil-water separation. 2. Installation specifications: Ensure that the oil-water separator is installed according to the manufacturer's specifications, including correctly connecting the inlet and outlet pipes, and ensuring that the equipment is stable. 3. Correct operation: Operators need to understand and follow the correct operating procedures, including turning on and off the equipment, and regular cleaning and maintenance. 4. Regular maintenance: Clean and maintain the oil-water separator regularly to prevent grease accumulation and equipment failure. Here are some specific precautions: - Grease temperature control: During the separation process, control the temperature of the grease to avoid affecting the separation effect due to too high or too low temperature. - Water quality monitoring: Regularly monitor the water quality of the discharged water to ensure that the water quality after separation meets the relevant environmental protection standards. - Prevent secondary pollution of grease: During the separation process, prevent grease from entering the rainwater pipe network or sewer to cause secondary pollution. - Proper treatment of separated grease: Properly treat the separated grease, such as making it into biodiesel or other usable products. - Compliance with laws and regulations: Comply with national and local laws and regulations on the treatment of food waste to ensure that the treatment process is legal and compliant. - Employee training: Provide necessary training to operating staff to ensure that they understand the use and maintenance points of the equipment. - Emergency treatment: Develop emergency plans to deal with possible equipment failures or operating errors. Through the above measures, the effect of oil-water separation of waste cooking oil can be effectively improved while reducing the impact on the environment.
