Background
In China, the water crisis caused by water resource shortage and water pollution aggravation has become one of the most serious problems in the twenty-first century. For this reason, the produced waste water is usually recycled or discharged after reaching the standard when the production activities are carried out. The thermal power factory can use large-scale equipment and some supplementary equipment machinery in daily operation, and these equipment often can discharge oily waste water in service, and improper handling can cause serious influence to the environment. Its main sources are mainly three: (1) oily wastewater generated by heavy oil equipment used by a power plant mainly comes from cooling water of a pump, condensed water generated by the equipment and wastewater generated in maintenance;
(2) oil-way systems of power plant equipment transmission equipment, bearings and the like leak in the operation process, and the generated wastewater is mostly oily wastewater;
(3) oily wastewater generated in the operation or maintenance process of electrical equipment such as transformers, high-voltage oil switches and the like.
The oil content of the oily wastewater generated by a power plant is generally 500-2000 mg/L, and the oily wastewater mainly comprises floating oil, dispersed oil, emulsified oil and dissolved oil, wherein the emulsified oil needs a long time for demulsification through a standing method, continuous operation of oily wastewater equipment is not facilitated in practical use, and non-demulsifying oil components flow out along with clear water to enter a water production side in the gravity separation process, so that the COD (chemical oxygen demand) and oil substances of the oily wastewater do not reach the standard, and the condition of recycling system produced water is difficult to realize. In order to achieve demulsification of emulsified oil, common methods include a flocculation method, an air floatation method and the like, and although the flocculation method and the air floatation method can achieve the function of demulsification, the flocculation method has the defects of large occupied area, high investment cost and medicament waste. The air floatation method has limited effect on emulsified oil, the deterioration of demulsification effect can influence the quality of produced water, if the emulsified oil is directly discharged into an industrial wastewater station for retreatment, the load of industrial wastewater treatment equipment is inevitably increased due to the existence of the emulsified oil, the running cost of the industrial wastewater treatment station and the complexity of treatment process are increased, the quality of effluent water is influenced, and the use of next-stage process on reuse water is further influenced. This water must therefore be treated in a reasonably separate manner by suitable process technology.
