农业用水水质安全及用臭氧对污水无害化处理

Safety of Irrigation Water Quality and Sewage Purifying by Qzone

我国是农业灌溉大国 ,农业用水缺口大 ,水体污染严重。解决农业用水的出路 ,除了充分用好现有水资源 ,普遍实施节水农业之外 ,还需要把城镇居民生活污水和由于水体污染而不宜作为农业灌溉的这部分水 ,进行无害化处理并使之资源化 ,回收利用 ,这对舒缓未来农业用水危机有重要作用。该文重点探讨了用臭氧对污水进行无害化处理的原理及可行性。通过污水无害化处理 ,使农业用水水质安全有了保障 ,农产品不受污染 。

China is not only a big agricultural but also a water lacking country. Its irrigation water is lack far from enough. Moreover, the water is seriously polluted. The problem of irrigation water is solved not only by making good use of the existing water resources and developing the water saving agriculture, but also by purifying the sewage and polluted water. This paper disscussed the mechanism and the feasilility of sewage purifization by ozone. Making full use of the recycled water will contribute much to ease off possible crisis of shortage of irrigation water.
