Surfactants are widely used in many sections of our life. In general, the mass of surfactants are directly discharged into the environment after used. Biodegradation is the main way to remove it. There are two dramatic innovations in the history of surfactants industry. One is the transformation happened in the 50s of last centry from TBS used in the detergents to LAS. The other is the transformation happened in the ends of last centry from DSDMAC used as textile softener to EQ. Two transformations are caused by their biodegradability. In addition, countries in Europe setup green obstruction to limit the export of our country, which will baffle the economic development of our country. So whatever from the point of environmental pollution or economical development, it is very important to know about the biodegradation of surfactants at present in our country.In this article, the activated sludge is incubated in the first, thenadapated in the second, and inoculated to degrade surfactants in thelast. The results show that:...
