中文摘要:

有毒重金屬對環(huán)境的嚴重威脅正逐漸成為全球性問題，著重綜述了近年來國內(nèi)外重金屬污染處理技術(shù)的研究與進展。除了改進傳統(tǒng)的化學(xué)、物理方法外，各種廉價高吸附性能的吸附劑、新型可選擇性重金屬捕集劑都是研究的焦點。特別是隨著生物技術(shù)的發(fā)展，利用功能菌和植物處理含重金屬污染已取得相當成效，并在工業(yè)上進行了實際應(yīng)用。研究和發(fā)展新型天然吸附劑、重金屬捕集劑和生物技術(shù)，加強多種技術(shù)的綜合應(yīng)用，是治理重金屬污染的有效途徑。

英文摘要:

The serious threat of poisonous heavy metal pollution to the environment becomes a global problem. The researches and developments on heavy metal pollution treatment at home and abroad are summarized in this paper. Besides the improved traditional chemical and physical methods, the low-priced, high adsorption properties of adsorbent and new style heavy metal chelating agents are the focus of research.With the development of biological technology, functional bacteria and plants are more efficient in heavy metal treatment and are pratically used in industries. Combined application of various technologies is the potent way to heavy metal treatment based on advances of new-style natural adsorbents, heavy metal chelating agents and biological technology.
