摘要:

The apparent stoichiometry observed, the ozone to phenolic compound oxidized is equal to 7 (8)/1, 5/1, 4/1 respectively for tri–, di– and mononitrophenols. All nitrogroups are found to be in the form of nitrate in the medium after reaction. In a buffered medium uith NaHCO3; (pH 7.5–B), the results are consistent uith the bicarbonate – carbonate competition in indirect ozonization.

摘要:

One means of doing so is to generate very reactive oxidant entities in the medium without fundamentally modifying its physico–chemical characteristics. Among the techniques which can be used, the initiation of radicals can be done through irradiation or through the combined action of oxidants, such as hydrogen peroxide associated with ozone.

摘要:

Ozonation is used for the tertiary treatment, particularly for removal of colour, of the effluent from a night soil treatment plant in Japan. The practical system for effectively controlling the ozone treatment was investigated. The optimum ozonation was accomplished by monitoring the colour. This treatment plant worked in response to a sudden variation in the quality of raw water, i. e., nitrite ion concentration, COD, etc, and the quality of the ozonated water was kept at the levels of COD of 20 ~ 30 mg/2, and colour of 30 units. The water treated by this ozonation plant was found to be free from coliform bocilli, and to exhibit neither so strong acute toxicity to fishes nor mutagenicity.

摘要:

Accordingly, residual ozone contained in discharge vents after tertiary treatment can be usefully reinjected into the purification tank, thereby preventing release into the atmosphere of gaseous effluents containing ozone.

摘要:

ABSTRACT: Center, type and underline Abstract heading, capitalizing the first letter. A double-space should separate the heading from the abstract text. Indent approximately 1/2 inch (13 mm) from both left and right margins for typing the abstract. The abstract should be approximately 50 to 70 words in length. It should be factual and contain the main results and conclusions of the paper. It should be intelligible to the reader without reference to the body of the paper and be suitable for reproduction by abstracting services. Introduction to the text (without a heading) should begin two spaces below the abstract using full margins.
