Aging sludge on tank bottom

Aged sludge at the bottom of the tank is a mixed sludge precipitated at the bottom of the tank, mainly composed of grease residue, water, sediment, etc. This sludge is usually formed due to aging of grease, accumulation of water and precipitation of impurities in the tank due to long-term use or improper treatment. Physical and chemical methods such as high-temperature pyrolysis, dissolution cleaning, dilution separation and other technologies can be used to treat aged sludge at the bottom of the tank to separate and treat grease and impurities to reduce waste of grease resources and environmental pollution. When treating aged sludge at the bottom of the tank, the appropriate treatment method should be selected according to the specific situation, and attention should be paid to environmental protection requirements to avoid secondary pollution. The steps to continue to treat aged sludge at the bottom of the tank may include the following aspects: 1. Separation of grease and solid impurities: Use oil-water separation equipment or centrifugal separators and other processes to separate grease and solid impurities in the aged sludge at the bottom of the tank for subsequent treatment. 2. Pyrolysis treatment: Through high-temperature pyrolysis technology, the residual grease in the aged sludge is pyrolyzed and decomposed to extract reusable grease components. 3. Dissolution cleaning: Use solvents or cleaning agents to dissolve and clean the grease and impurities remaining in the aged sludge to achieve the effect of cleaning and separation. 4. Refining treatment: Re-refining the aged sludge after preliminary treatment to extract reusable oil components, and at the same time separate and treat solid impurities to reduce the amount of waste. 5. Environmental protection disposal: After treating the aged sludge, the residual waste and wastewater are treated in an environmentally friendly manner in accordance with relevant environmental protection laws and standards to avoid pollution to the environment. Through the above treatment steps, the aged sludge at the bottom of the tank can be effectively treated, reusable resources can be extracted, waste emissions can be reduced, and resource recycling and environmental protection effects can be achieved.
