Establishment of the defense system for wastewater environmental risk in petrochemical industry

Petrochemical industry in China is of great risk in safety and environmental aspects. It can cause significant loss because of the related accident. However, the defensibility of wastewater risk is very weak for petrochemical enterprises at present. Thus the problems found in the defense facilities are pointed out and the building of the entire defense system for wastewater risk is discussed in the present paper. Moreover, the necessity and properties for the establishment of retention pond are emphasized. It is expected that this paper will be benefit for the management, defense and disposal of wastewater accident emergency in petrochemical industry.
