项目摘要

Development of the method for purification of pollution caused by dioxins, environmental hormones, and pesticides residue using immobilized enzyme and crude enzyme from dioxins degradable fungi was tried.1.Effect of degradation rate on concentration of entrapment agents as well as the enzyme activity in immobilized enzyme retained by entrapment was clarified. The method for purification of dioxins, environmental hormones and pesticides residue in soil was developed. Forty five to 80% of TCB, PCDD/Fs, DDT and Lindane were degraded by the method for 30 days. Furthermore, the immobilized enzyme with dual-membrane was also prepared. However, the degradation rate was almost same as that of the immobilized enzyme with single-membrane.2.The method for degradation of dioxins (TCB, PCDD/Fs) by bioreactor using immobilized enzyme as a degradation agent in a short period was developed. The degradation rate of TCB and PCDD/Fs for 72 hours were 65% and 60% (comparison of TEQ value with that of untreated soil), respectively. The degradation rate by the method using bioreactor was five times faster than that by the method without using bioreactor. This method can be applicable to purification of pollution caused by environmental hormones and pesticides residue.3.Since incinerated ash was alkaline and optimum pH (pH 4.5) of the crude enzyme is different from the pH of the ash, it was proven that many enzymes were necessary for the degradation of dioxins, though the degradation was occurred in a low rate (about 30%). Further, dioxins could not almost degraded by using immobilized enzyme for the much inorganic salt in incinerated ash. However, the method for purification of incinerated ash by using dioxins degradable fungus as a degradation agent was developed. Dioxins in incinerated ash were degraded by the method for 30 days (40%, comparison of TEQ value with that of untreated ash).

本研究尝试了利用固定化酶和二恶英降解菌粗酶净化二恶英、环境激素和农药残留污染的方法。1.明确了降解率对包埋剂浓度的影响以及包埋后固定化酶中酶活的保留情况。建立了土壤中二恶英、环境激素和农药残留的净化方法。30天内，TCB、PCDD/Fs、DDT和林丹的降解率为45%~ 80%。此外，还制备了双膜固定化酶。2.建立了以固定化酶为降解剂的生物反应器在短时间内降解二恶英（TCB、PCDD/Fs）的方法。TCB和PCDD/Fs的72 h降解率分别为65%和60%（TEQ值与未处理土壤相比）。使用生物反应器的方法比不使用生物反应器的方法的降解速率快5倍。该方法适用于环境激素和农药残留污染的净化。3.由于焚烧灰呈碱性，且粗酶的最适pH（pH4.5）与灰的最适pH不同，证明了二恶英的降解需要多种酶的参与，但降解率较低（约30%）。此外，由于焚烧飞灰中无机盐含量较高，固定化酶对二恶英的降解效果较差。然而，开发了通过使用二恶英降解真菌作为降解剂来净化焚烧灰的方法。焚烧灰中的二恶英降解的方法为30天（40%，TEQ值与未处理的灰相比）。
