College of Architecture Civil Engineering, Zhejiang U niversity of T echnology, Hangzhou 310032, China; 2. Zhejiang Tiantai Environmental Monitoring Station, T iantai 317200, China) Abstract : Pollution of chemical wastewater discharge to the environment was severe with the eco nomic development. Organic pollutant in the wastewater discharged from the chemical product processes is always complicated, noxious and hard to be subtracted. T herefor, new chemical wastewater treatment processes and techniques with the high efficiency and low costs have be come the research emphases of the wastewater treatment area. The basic characteristics and trea ting conditions of chemical wastewater were presented, and the new progress and trend of the processes were overviewed. In the end, it also put forward suggestions to the research point. Based on the results of research and application, the chemical wastewater treatment technique was sugg
