| 简介 |
PROBLEM TO BE SOLVED : To provide a water cleaning apparatus for obtaining secured water for domestic use by treating raw water contaminated particularly with inorganic harmful substances such as arsenic, lead, chromium, cadmium, mercury, etc.
SOLUTION : The toxicity of the harmful substances in the raw water is reduced by adding an oxidizing agent to the raw water to form hardly water-soluble oxides from the harmful substances. The target compound can be removed from the water as a precipitate in the oxidation process when the compound has a high density. The invention provides not only the cleaned water without the inorganic harmful substances but also the following advantages over the conventional apparatuses : 1, the initial cost is low; 2, the running cost is low; 3, the waste collected becomes a valuable matter containing rare elements; 4, the waste water is reduced; and 5, the apparatus is simple. |
