METHOD AND DEVICE FOR REMOVING ORGANIC MICRO-POLLUTANTS IN WATER

WIPO Patent Application WO/2022/011847

A1

The present invention belongs to the technical field of sewage treatment, and discloses a method and device for removing organic micro-pollutants in water. The method comprises the following steps: S1, aerating remaining sludge under starvation conditions so as to enrich hungry state microorganisms; S2, treating sewage containing organic micro-pollutants under aeration conditions by using the sludge containing hungry state microorganisms obtained in step S1; and regularly updating the sludge containing hungry state microorganisms. In the present invention, the sludge is treated under oxygen starvation conditions, so that microorganisms that can only use easily degradable organic matter are gradually eliminated, and microorganisms that can use complex organic matter contained in the sludge itself are enriched. The enriched sludge may degrade a variety of organic micro-pollutants, and may be used to remove organic micro-pollutants in sewage. The process is simple to operate and low in cost, and has a high practical application value.
