APPARATUS AND METHOD FOR TREATING WASTE WATER - A simplified explanation of the abstract

This abstract first appeared for US patent application 18200615 titled 'APPARATUS AND METHOD FOR TREATING WASTE WATER

Simplified Explanation

The patent application describes an apparatus for treating waste water using a series of flocculation tanks, sedimentation tanks, and a nitrification tank.

• The first flocculation tank treats waste water with a first flocculant to coagulate fluorine.
• The second flocculation tank treats the outflow water from the first tank with a second flocculant and carbon dioxide to flocculate residual fluorine.
• The third flocculation tank treats the outflow water from the second tank with a third flocculant to further flocculate materials.
• The first sedimentation tank separates the water from the third tank into sludge and supernatant water.
• The nitrification tank uses carbonate from the carbon dioxide to provide alkalinity and oxidizes ammoniacal nitrogen in the supernatant water.
• The second sedimentation tank separates the water from the nitrification tank into sludge and supernatant water.

1. 1. 1. Potential Applications

- Municipal wastewater treatment plants - Industrial wastewater treatment facilities - Water treatment for agricultural runoff

1. 1. 1. Problems Solved

- Coagulation and flocculation of fluorine in waste water - Solid-liquid separation of flocculated materials - Nitrification of ammoniacal nitrogen

1. 1. 1. Benefits

- Efficient removal of fluorine from waste water - Reduction of pollutants in water bodies - Compliance with environmental regulations

Original Abstract Submitted

An apparatus for treating waste water including: a first flocculation tank to which a first flocculant is provided to produce a first flocculated material in which fluorine in waste water introduced from a waste water storage part is coagulated; a second flocculation tank to which a second flocculant and carbon dioxide are provided to produce a second flocculated material in which the first flocculated material and residual fluorine in first outflow water introduced from the first flocculation tank are flocculated; a third flocculation tank to which a third flocculant is provided to produce a third flocculated material in which the first flocculated material and the second flocculated material in second outflow water introduced from the second flocculation tank are flocculated; a first sedimentation tank in which third outflow water introduced from the third flocculation tank is solid-liquid separated into first sludge containing the third flocculated material and first supernatant water; a nitrification tank in which alkalinity is provided by a carbonate supplied from the carbon dioxide, and ammoniacal nitrogen in the first supernatant water introduced from the first sedimentation tank is oxidized by nitrifying microorganisms; and a second sedimentation tank in which fourth outflow water introduced from the nitrification tank is solid-liquid separated into second sludge and second supernatant water.
