项目摘要

(1)PurposeNow a day, defractory compounds such as chlorinated organic compounds and environmental hormones become social problems because of their effects on human and animals. It is an urgent subject to develop the treatment process to decompose these compounds economically and efficiently. In this research, we have aimed to develop technology for treatment of extremely undegradable aromatic and aliphatic organic compounds and examine their reaction mechanisms.(2)ResultsVarious refractory compounds were converted to be biodegradable ones with strongly oxidative ozone and activated chlorine which was produced electrochemically. The conversion mechanisms were made clear. These converted compounds were easily degraded to carbon dioxide by microbes.The combined treatment process of biological and chemical technologies was applied to the following typical industries wastewaters and the pollution compounds involved were reduced efficiently : (1) wastewater from polyvinyl chloride manufacturing plant, (2) photographic wastewater, (3) wastewater from manufacturing process of a photoresist substrate for semiconductor, and (4) wastewater from electro-less plating process for electronics and information industries. The basic treatment processes for the above wastewaters were designed.(3)ProspectIn future research, we will try to evaluate the treatment process developed in the present research from viewpoints concerning performance, cost and operation and to transfer our technology to industrial sector. And also, it is the subject to examine acute and chronic poisonous, hereditary and hormonal natures of treated waters.

(1)目的氯化有机化合物和环境激素等有害化合物由于对人类和动物的影响而成为当今社会的问题。开发经济高效地分解这些化合物的处理工艺是一个迫切需要解决的问题。在本研究中，我们旨在开发处理极不可降解的芳香族和脂肪族有机化合物的技术，并研究其反应机理。(2)结果多种难降解化合物在强氧化臭氧和活性氯的作用下转化为生物可降解化合物。转换机制是明确的。这些转化的化合物很容易被微生物降解为二氧化碳。采用生物与化学相结合的处理工艺，对聚氯乙烯生产废水、照相废水、半导体光刻胶基板生产废水、电子信息工业化学镀工艺废水等典型工业废水进行了有效的处理，有效地降低了污染化合物。设计了上述废水的基本处理工艺。(3)展望在未来的研究中，我们将尝试从性能、成本和操作的角度来评估本研究开发的处理工艺，并将我们的技术转移到工业部门。同时，它也是检查处理过的水的急性和慢性毒性、遗传性和激素性质的主题。
