How to treat the type and nature of waste oil? What measures should be taken to prevent? According to authoritative statistics, 70% of urban water pollution disputes are caused by over-standard petroleum. Controlling excessive emissions of petroleum-based products is an important task of preventing and controlling water pollution in enterprises. The discharge of petroleum standards is a systematic work, and only by taking targeted management measures and advanced management techniques can we effectively control oil-water pollutants in water to ensure compliance with petroleum standards. There are several properties of waste oil treatment: 1, oil slick: its proportion is less than water, the formation of floating in the water separation layer. It accounts for 60% -80% of oil, generally using gravity separation. My company's slick oil handling facilities mainly used advection grease trap, the principle of its treatment is the use of the proportion of poor separation, for the proportion of less than water, the use of skimmers skimmers income oil storage tank recovery. This method works best for treating heat-treated oily wastewater. 2, dispersed oil, emulsified oil: the two states of the oil are long-standing can not be stratified oil, to deal with this type of oil is mainly used to take the coarse-grained device or flotation method to be removed. Especially the flotation effect is better, the main principle is the use of a large number of micro-bubbles generated by the aerator to promote its adhesion to impurities, the formation of less than the proportion of water floating body, so as to obtain separation of impurities a water purification method for Commonly used to promote aerosol adhesion coagulant (polyaluminum chloride, polyaluminum chloride). 3, dissolved oil: As the solubility of petroleum in water is minimal, therefore, such oil content is very low, generally do not consider recovery and treatment. Waste oil recovery management analysis: 1, the source of waste oil Waste oil from machinery enterprises mainly in the mechanical products processing, cleaning, lubrication, cooling and product heat treatment, mechanical equipment and equipment operation, the transmission process, if these oils can be Recycling, you can significantly reduce the amount of oil discharged into the sewer pipes, reducing the technical difficulty of the follow-up treatment, while recycling of waste oil can have considerable economic benefits. 2, the type and nature of waste oil From the generation of waste oil can be seen, the generation of waste oil can be broadly divided into two categories: one is to be reused for the recovery of impurities in oil, such oil by strengthening waste Oil recovery management can be reused after simple treatment, the other is difficult to recover oil spilled on the ground after the rain washed into the sewage sewer wastewater, such oil in the water mixed with water in the process of both physical mixing Emulsification, dissolution of the physical and chemical processes, the nature has changed, forming a slick, dispersed oil, emulsified oil, dissolved oil collectively referred to as oily wastewater. In addition to oil slick can be used, the state of the oil has no value in the treatment, but must be treated by reliable technology before they can reach the emission standards for environmental pollutants. This shows that the recovery of waste oil management must be based on the source of waste oil, type, nature can be recovered in order to achieve better results. At the same time to achieve environmental emissions standards must be advanced management tools as a guarantee. 3. Measures for Recovery of Waste Oil To strengthen the recovery of waste oil, which is the basic work to achieve the unified goal of environmental benefits and economic benefits, we have taken the following measures: 3.1 To formulate a practical recycling management system to enhance the utilization of waste oil in the production process Recycling. 3.2, strengthen environmental protection publicity and education work, improve staff awareness of environmental protection, strict control of waste oil into the drain. In order to reduce the substances that may cause pollution to the environment, such as acid residue and waste water generated in the chemical treatment process, the filter-polyaluminum chloride manufacturer recommends using a non-polluting process that is conducive to the protection of the environment. In order to reduce the cost of waste oil regeneration and encourage the use of Recycled waste oil for China's industrial waste oil recycling make a contribution.
