Determination the component of foaming agent and its natural degradation characteristics
A lot of foaming agents are used during the mining mineral processing.The foaming agent is hard to degrade and remains in the wastewater and chemical oxygen demand (COD) is far exceeded the standard in mine water.In this paper,the component of foaming agent made in Guangxi province was determined and analyzed through experiments.At the same time,the effect and the contribution of foaming agent to the COD materials in the water were also been studied.The degradation performances of foaming agent in different conditions such as pH,initial density and temperature,with aeration or without aeration,with ultraviolet ray or without ultraviolet ray were studied particularly.The result of this study provided the scientific basis in choosing the appropriate new environmental foaming agent and reduced the content of COD in the flotation wastewater.
