At present, it is so prominent in the development of the petrochemical industry in China，and it is accompanied by petrochemical wastewater, which has become a big problem need to solve urgently.Because petrochemical wastewater mainly contains benzene-compound, organic matter, high salt wastewater and oil sewage, etc. They are very damaging and highly contaminated. The composition and properties of the petrochemical wastewater were introduced firstly, the current situation of petrochemical wastewater treatment at home and abroad were reviewed in the study. Especially the development of petrochemical industry in sichuan was introduced. Based on the present situation and the existing problems, put forward some countermeasures and expect technique develop direction in the future.

AbstractOff-the-books, untraceable “ghost guns” can now be manufactured at home, easily, and in large numbers; they contribute ever more frequently to firearm violence, including hate violence and domestic terrorism. The Bureau of Alcohol, Tobacco, Firearms and Explosives estimates that in 2019 alone, law enforcement agencies recovered more than 10,000 ghost guns. The manuscript describes the current situation and suggests specific actions that state and federal governments can take to avert disaster.

Asphalt aging is inevitable to the asphalt pavement performance, which will lead asphalt to hardening gradually and becoming brittle. Therefore, aging progress shortens the life of asphalt, but the study on polymer asphalt improves the phenomenon. The present situation on aging of polymer modified asphalt is summarized and the aging mechanism of modified asphalts is analyzed in the paper. Otherwise, the research progress at home and abroad on the aging properties of modified asphalt is introduced by a series of characterization techniques, which include mechanics technique, rheology technique, FTIR, GPC and so on
