水体中典型环境激素处理技术比较

COMPARISON OF THE TREATMENT TECHNOLOGIES TO TYPICAL ENVIRONMENTAL HORMONES IN WATER BODY

环境激素中,雌酮(E1)、雌二醇(E2)、乙炔基雌二醇(EE2)、雌三醇(E3)的相对雌激素活性(EEF)较大,双酚A(BPA)分布较广。在结构上,它们都是不饱和环状结构;在性质上,具有高分子量、非极性、难溶于水以及难挥发等特点。根据E1、E2、EE2、E3及BPA的结构和性质,分析比较生物法、物理法以及化学法(高级氧化技术)的优缺点,针对环境激素这类具有污染范围广、浓度低、难降解以及污染源长期存在等特点的有机污染物,充分发挥各种处理技术的优点,寻找经济、高效的处理环境激素的方法。通过分析比较,将高级氧化技术与生物法配套处理环境激素的联合工艺是一种比较高效、经济合理的处理方法。

In Environmental hormones,Estrone（E1）,estradiol（E2）,ethynylestradiol（EE2）,estriol（E3） are of large respectively estradiol equivalency factor（EEF） and bisphenol A（BPA） is widely distributed in aquatic environments.In the structure they are of unsaturation annular structure,and in the properties,they all have the characteristic of high molecular weight,nonpolar,insoluble in water and volatile.According to the structure and properties of the E1,E2,EE2,E3 and BPA,we would comparative analyse the advantages and disadvantages of biological,physical and chemical method（advanced oxidation technology）.For environmental hormone,which have the characteristics of wide range pollution,low concentration,hard-degradation and longly existing of pollution sources,We should fully exert the advantages of various processing technology and find an economic and efficient method of handling environmental hormones.The union technology of advanced oxidation technology or new plasma technology with biological method to deal with environmental hormones are more reasonable and efficient than other treatment method.
