Water bottom oxygenation method

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.

Description

technical field [0001] The invention belongs to the technical field of environmental protection water treatment, and relates to a method for oxygenating the bottom area of ​​the most anoxic water body, which is mainly used for ecological restoration and water quality improvement of surface waters such as rivers, lakes, reservoirs, ponds, artificial landscape water bodies, etc. , as well as deep water aeration in the field of industrial sewage and domestic sewage water treatment. Background technique [0002] In the field of industrial sewage and domestic sewage water treatment, various aeration equipment is widely used to increase dissolved oxygen in water bodies; various aeration equipment is often used in ecological restoration and water quality improvement of surface waters such as rivers, lakes, reservoirs, ponds, and artificial landscape water bodies. Aeration equipment for aeration and oxygenation. There are many types of these common aeration equipment, including var...

AI Technical Summary

Problems solved by technology

[0007] For the water treatment aeration tank of industrial sewage and domestic sewage, ordinary aeration equipment cannot oxygenate the deep water area of ​​the pool, which means that the aeration tank cannot be built too deep, which leads to a large area of ​​sewage treatment plant

For surface waters such as rivers, lakes, reservoirs, ponds, and artificial landscape water bodies, ordinary aeration equipment cannot oxygenate deep water areas, which means that the dissolved oxygen at the bottom of the water body with the most deposited organic matter and the least dissolved oxygen will not be significantly improved. It is very unfavorable for ecological restoration and water quality improvement
