<p>PURPOSE: A method for purifying waste water utilizing microorganism and air uses ideal flow in activation tank and mixing. CONSTITUTION: The method will purify waste water using mixed waste water,microorganism, and air in a short time. In activation tank, an inside circulation pipe is installed in the activation tank, and circulation nozzle is fixed at the end of the circulation pipe. The ratio of section area must be more than 1 to 1, and air must be flown into the activation tank compulsively. The method is available for supplying oxygen to microorganism, minimizing treatment time, stabilization of operation, operational efficiency, and saving operation cost. The method can be used for purifying organic and inorganic material, and water cleaning using ozone.</p> |
