Abstract: The invention discloses a double-tank oxidation pond for evaluating catalytic ozonation efficiency, comprising detachable tank bodies made of organic glass, movable ozone aeration pipes and sampling holes. Each tank body has three sections. The height of ozone aeration tube and the number of the holes can be adjusted. The holes are distributed at different positions of the tank bodies for real-time in-situ sampling. It is easy to observe the distribution profile of the gas, liquid and solid phases in the tank bodies. The square double-tank structure is similar to actual production process, and thus the experimental data is easy for computer simulation to enlarge to the actual production process. The size of the ozone aeration pipe and the position of holes in the tank can be adjusted to evaluate the catalytic ozonation effect of sewage treated by different aeration ways and aeration heights.

Abstract: Waste water is remanufactured with ozone in a series of mixing vessels. The ozone is dispersed to both a top and a bottom portion of each mixing vessel, but in different amounts. This creates an electrical potential difference across the height of each mixing vessel which significantly improves the oxidation of organic carbon-based impurities and eliminates H2S and bacteria. Sludge and solids floating to the top of each mixing vessels are removed, as well as sludge and solids settling to the bottom of the mixing vessels. When oil and gas well waste water is treated in this manner, the resulting treated water is purified and has a high salt content suitable for oil or gas well injection.

Abstract: A process of dissolving into to-be-treated water a peroxodisulfate and metal ions other than ions of alkali metals is performed by pouring equipment. An ultraviolet irradiation apparatus performs a process of treating the to-be-treated water, having the peroxodisulfate and the metal ions other than ions of alkali metals dissolved therein, with ultraviolet rays. By performing UV treatment on the to-be-treated water having the peroxodisulfate and metal ions dissolved therein, the inventive method and system achieve improved TOC decomposing performance and thus can particularly decompose a urea component in an efficient manner. Further, the to-be-treated water may be treated with an ion-exchange resin at a subsequent stage in such a manner that organic acids contained in the to-be-treated water having been subjected to the UV treatment are adsorbed to the ion exchange-resin, with the advantageous result that the concentration of TOC present in the to-be-treated water can be reduced.
