Petrochemical enterprises is an important pillar industry of China's national economy, the petrochemical production process involves a lot of toxic, hazardous, flammable, explosive nature of the raw materials, intermediate products and final products. Organic waste water used in the production process and produce environmental pollution is very serious, complex, and it is likely to cause heavy, serious water pollution accidents. With the new construction and renovation projects in petrochemical enterprises, built and put into operation, the the petrochemical enterprises organic wastewater environmental risk is becoming increasingly prominent. Industrial organic wastewater is the main water source of pollution. With the development of modern heavy chemical industry and paper printing and dyeing industry, expanding production scale produced large amounts of toxic and hazardous substances difficult to timely processing, and ineffective due to local regulatory wastewater discharge vast quantities of natural environment pollution increasing, especially in oil the top of the emission of chemical, rubber, pesticides, printing and dyeing, paper and other industries. Industrial organic waste water has strong anti photolysis, biodegradation resistance and oxidation resistance, the complex pollutant components, content, and toxic biochemical degradation, environmental pollution is serious, the deterioration of the surface water bodies, a serious threat to human health. Due to the special nature of petrochemical production, unparalleled complexity and importance of the recognition of the environmental risks of organic wastewater than other evaluation projects. Electrochemical Oxidation of organic wastewater treatment method as an excellent environmentally advanced oxidation technology, more and more attention in the field of environmental protection, this technology has a good environmental compatibility, adaptability, saving chemical reagents, easy to operate and no secondary pollution characteristics. But so far, there are many problems to be solved, the electrochemical oxidation of industrialization, there is still a considerable distance, so it is necessary to degradation of organic wastewater in-depth study of the electrochemical oxidation treatment. However, the electrochemical oxidation treatment degradation of organic wastewater electrode efficiency is not satisfactory due to the low current efficiency, processing power consumption, and the poor economy in the practical application of industrial production. Development and use of new energy sources, especially the use of solar energy, not only energy saving, but also can reduce environmental pollution, improve the human living space, and improve the quality of human life. Therefore, the use of solar energy for the electrochemical oxidation treatment of organic wastewater study has important implications. The electrochemical oxidation treatment of organic wastewater, the electrode material on the oxidation performance is particularly important, requiring both conductive, but also to activate the reactants and improve the rate of electron transfer, electrochemical reactions play a catalytic and selective role. Thus, the design and preparation of the electrode material has a higher requirements. Rare earth lanthanum process and transition metal-doped electrode preparation of the introduction of the drilling process, nickel process, so that changes in the surface microstructure of Ti-PbO2 sedimentary prone to more active centers can improve the high target pollutants electrolysis reaction absorption and high reactivity requirements. Petrochemical enterprises organic wastewater environmental risk identification and electrochemical oxidation treatment, and do simulation experiment: first, the method of the petrochemical enterprises organic wastewater risk identification, features, content and methods. Second, to explore the principles and advantages and disadvantages of the electrochemical oxidation technology to treat organic wastewater. Explore the enormous potential of solar power and the use of solar power technology status, problems and prospects for the development of the economic outlook and solar power. And solar power for the petrochemical industry. The fourth, on the electrode treatment of organic wastewater. Ethylene Plant of Jilin Petrochemical Corporation ethylene plant, for example, according to the actual situation of the product and production devices to identify the environmental risks of the device organic wastewater. Sixth, the use of solar power to organic wastewater treatment ethylene plant simulation test and the test results are discussed. This paper described the the petrochemical enterprises organic wastewater environmental risk identification, can provide a theoretical reference for the environmental risk identification of the petrochemical enterprises organic wastewater, explore Preparation and Characterization of four electrodes, as well as the use of solar power generation electrochemical oxidation treatment of the ethylene plant organic wastewater conducted simulation experiments can provide reference for similar production plant organic wastewater treatment depth test.
