BKD-1 which was synthesized in the laboratory is an effective coagulator for the leachate to decrease COD、color and odor, and the sediment velocity is fast. The function of the-OH group was identified by IR. Fenton, the reagent was studied systematically for leachate processing; Activated charcoal acts as a catalyst in the oxidation-reaction.

本研究采用自行研制高效混凝剂—BKD-1预处理渗滤液效果明显好于其它常规无机混凝剂和有机絮凝剂PAM，COD和色度去除率较高，絮体沉降快，采用红外光谱分析表明羟基架桥作用是该混凝剂混凝的主要机理之一。

Moreover, human activities play a more and more important role in the development of tidal flat. The concentrated coastal engineering change the dynamic environment of the tidal flat, and the exploitation of oil, natural gas and groundwater results in surface subsidence in the coastal area. In addition, sea level rise and the accompanied increase of storm surge frequency and intensity, will strengthen the erosional process, reduce the tidal flat area, coarsen the sediment, made the slope steep, and cause other environmental effects.
