| 简介 |
A process effects the electrochemical oxidation and/or the reduction of dissolved or absorbed pollutants in the presence of media containing particulate substrates, or media holding particles, in the presence of aqueous electrolytes and an artificial electrical potential field. The novelty is that : (a) the substrates or media are artificially enriched with semiconductors; (b) the semiconductors consist primarily of inorganic or organic semiconductors; (c) inorganic semiconductors contain primarily iron or manganese; (d) the semiconductors are enriched with such metals as are reduced electrochemically to metals under the influence of the potential field; (e) the organic semiconductors are primarily humic materials; (f) the active particulate substrate ingredients are in precipitated form; (g) the semiconductors are enriched directly or indirectly by the effect of an electrical potential field; (h) the particular substrate or media is soil, sediment or water in its natural position, or earth, sludge, waste water, ground water, drinking water, swimming pool water; and (i) the particulate substrates are process media such as filter gravel, flocculants, sediment producers, sludge thickeners or foul sludge. |
