Method and device for post-treating waste water from sewage plants
First Claim
Patent Images
1. A method of treating waste water discharged from a water purification or sewage treatment plant, the method which comprises:
- providing waste water containing an amount of organic substances including endocrinally active hormones and hormones dangerous to aquatic environments or hormone metabolites from the group of estranes;
reducing the amount of organic substances contained in the waste water substantially solely by guiding the water in form of a continuous fluid body through a field or radiation cone of at least one radiation source emitting ionizing radiation selected from the group consisting of gamma radiation, x-ray radiation, and electron radiation, and substantially without adding either one of ozone or oxygen.

Abstract
A method and a device allow treating waste water discharged from a purification or sewage treatment plant for local waste water. An amount of endocrinically active hormones and hormones dangerous to aquatic environments or hormone metabolites from the group of oestranes contained in the discharged water is reduced in the flow of the waste water leaving the waste-water purification or sewage plant by guiding the same in the form of a continuous fluid body through the field or radiation cone of a radiation source emitting ionizing radiation (gamma, x-ray, and/or electron radiation).

14. A device for treating waste water discharged from a water purification or sewage treatment plant, the waste water containing an amount of organic substances including endocrinally active hormones and hormones dangerous to aquatic environments or hormone metabolites from the group of estranes, the device comprising:
-
an electron radiation source configured to reduce the amount of organic substances contained in the waste water substantially without adding either one of ozone or oxygen;
at least one radiation-exposure chamber or radiation-exposure cell disposed in an effective area of electron radiation generated by said electron radiation source, formed with an inlet for receiving waste water that contains hormones and originates from a municipal waste-water treatment plant, an outlet for waste water with a reduced hormone content, and a window transparent to radiation or open to the radiation and facing said electron radiation source, and configured to effect a formation of a substantially stratified, flat, and continuously flowing fluid body. - View Dependent Claims (15, 16, 17, 19, 20)
