二类水体表观光学特性的测量与分析--水面之上法方法研究

水体光谱特性的测量与分析是海洋水色遥感的基础工作之一。水体光谱特性包括两个方面：表观光学特性和固有光学特性。现场直接获取表观光学特性有剖面法和水面之上法。在多次现场试验的基础上,主要针对二类水体从误差来源的角度来对水面之上法进行方法研究。同时,借鉴一类水体水面之上法的多种数据处理方法,对二类水体水面之上法的数据处理方法进行探讨。     

Hospital Laundry Wastewater Disinfection with Catalytic Photoozonation

Wastewater production in a hospital laundry and the treatment of the most critical wastewater stream, are assessed. Hospital laundry wastewaters are hazardous to the environment due to their high pollutant concentrations and the chemicals added during the clothes washing process. Heterogeneous photocatalysis with UV, O₃ and TiO₂ and their possible combinations were used for disinfection purposes. A ramp‐type reactor was used for TiO₂ (P25 Degussa) fixation and for photochemical diffusion of the ozonized air. After assessing 5‐day biological oxygen demand, chemical oxygen demand, pH, turbidity, and surfactant content, and checking for the presence of thermotolerant coliforms and Escherichia coli, it was concluded that UV/O₃/TiO₂ was the best process/combination, yielding a 100% disinfection rate and a microbiological inactivation of 0.5070 min^–1 for E. coli and of 0.5505 min^–1 for thermotolerant coliforms.     

利用直方图方法处理二类水体剖面数据研究

剖面法是国际上公认的测量表观光学量的首选方法,但在二类水体的数据处理中,其关键参数漫射衰减系数的数据处理误差较大.论文就此提出利用直方图分析的方法进行数据的处理,并选用2002年的黄海试验数据进行验证,结果表明,这种方法在一定程度上减小了主观因素对数据处理的不利影响,提高了数据处理的准确度.
