Abstract

The invention discloses a water bottom oxygenation method, aiming at solving the defects of the traditional aerating apparatus that dissolved oxygen is centralized on an upper layer and is difficult to reach a water bottom layer which is in lack of oxygen. In the water bottom oxygenation method, a common aerating apparatus and a water bottom horizontal stream establishment oxygen enrichment device which is additionally arranged near the common aerating apparatus are utilized, wherein the common aerating apparatus performs aeration and oxygenation on the upper layer, so that the dissolved oxygen in the upper layer of the water is rapidly increased, thus oxygen-enriched water is formed; and oxygen-enriched water blocks are sucked from the upper water by the water bottom horizontal stream establishment oxygen enrichment device arranged nearby and then are guided into the water bottom at a deep water region to be sprayed out, and a huge horizontal stream is formed at the water bottom, thereby achieving large-area water bottom oxygenation. The method can be used for a deep water aeration tank in a sewage treatment industry, so as to reduce the floor area; and the method can be used for bottom mud oxidation and inner source pollution load reduction, thereby being beneficial to rapid decomposition of deposited matters at the water bottom and the improvement of the water quality.
