综述我国造纸业污水中的污染因子危及地下水水质安全的机理，通过对野外试验和室内土柱试验的过程及结果进行分析研究，表明在包气带中形成一个以生物化学作用为主的生化层在造纸污水中COD降解是一个复杂的生物化学降解过程；生化层在天然状态下形成，由生物氧化带和生物氧化还原带形成，其形成过程具有明显的阶段性；只有当生物氧化还原带形成后，生化层才发育成熟，具备对COD降解的生化能力；生化层空间分布，仅局限在污水池、渠底部包气带中有垂向渗流的部分。

Although the intact-receptor based biosensors of the maxillary palp of cockroach Periplaneta Americana are not yet practical analytical devices at present. Yet, sensitive and selective responses to biomolecules involving amino acids and protein, as well as some simple substance such as salts and sugars have been firstly obtained. It is already evident that receptor based biosensors are enormously superior to isolated receptor biosensors in terms of response time and recovery times, thus, the intact receptor biosensor worth of further investigation and development.

总而言之，本论文首次从电生理信号上对美洲蜚蠊下颚须的化学响应进行研究，初步探讨了基于美洲蜚蠊下颚须的整合受体生物传感器的特性；发现了美洲蜚蠊下颚须能够整合其密集的感觉毛阵列对化学刺激的响应；得到了蜚蠊对氨基酸和蛋白质等生物分子以及简单物质如盐和糖等的敏感而具有选择性的响应信号，并发现了糖和蛋白质的特殊响应信号；表明了美洲蜚蠊下颚须是一种新型整合受体生物传感器的敏感材料，进一步深入地研究信号波形及其整合原理、探寻糖和蛋白质的特殊受体细胞等，对这一类型整合受体传感器的研究发展是很有意义的。
