摘要
[目的]研究入境废塑料加工处理过程对水环境的影响,以建立相应的检验检疫标准,防止含有有毒有害物质的废塑料入境。[方法]参考国家有关标准,对入境废塑料清洗废水的化学需氧量、pH值、重金属、半挥发有机物等进行检测分析。[结果]废水中的化学需氧量严重超标,并检测到我国现有污水排放标准中未明确规定限量的有毒有害物质双(2-乙基己基)酞酸酯。
To study the impact of imported used plastics on water environment during recycling and reusing, and to establish relevant inspection and quarantine strategies with regard to control and prevention of toxic chemicals carried by imported used plastics. In this study, COD, pH value, heavy metal elements, semi-volatile organic compounds and so on were analyzed in wastewater of used plastics during washing according to the reference methods of Chinese standards. The results showed that COD of wastewater samples were far go beyond the limit of standard. Bis （2-ethylhexyl） phthalate （DEHP）, a toxic chemical, was found in wastewater samples which hasn＇t been described in current standard on wastewater discharge.
