Intelligent control system for eutrophication of water body

Abstract

The invention discloses an intelligent control system for eutrophication of a water body, and relates to the field of sewage treatment. The intelligent control system solves the problem that the innerpollution source is formed in the water domain because the water does not contain dissolved oxygen, the death of a large amount of aerobes growing in water is caused, and the aerobes are settled to the water bottom, and then are rotted, deteriorated and deposited to form the sludge at the water bottom. The intelligent control system for eutrophication of the water body is technically characterized by comprising micro-nanometer aeration equipment, and a dissolved oxygen detection device, wherein the micro-nanometer aeration equipment can float on the water surface; the dissolved oxygen detection device is arranged at one side, near the water bottom, of the micro-nanometer aeration equipment and is used for detecting the condition of dissolved oxygen in the water. The intelligent control system for eutrophication of the water body has the advantage that the content of dissolved oxygen in the water can be increased, so as to indirectly avoid the death of aerobes and settling to the waterbottom.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an intelligent treatment system applied to water body eutrophication. Background technique [0002] In the era when human beings were few in number and living scattered, all waters in the environment basically maintained good quality. With the increasing frequency of human activities, the pollution of waters gradually increased. The reason is that the pollution emitted by human activities has exceeded The limit of the self-purifying ability of waters. [0003] All waters have a certain degree of self-purification ability. This self-purification ability comes from the dissolved oxygen in the water. If the water lacks oxygen, the waters must be seriously polluted. The higher the dissolved oxygen content in the water, the stronger the self-purification ability of the water area. Usually, the natural dissolved oxygen content in natural water areas is about 1ppm. When a small amount ...

Problems solved by technology

[0004] However, when the total amount of pollutants entering the water exceeds the self-purification capacity of the dissolved oxygen content in the water, the dissolved oxygen content in the water will be consumed after oxidizing and decomposing some pollutants, and the remaining pollutants will be dissolved and suspended with water. Molecules combine to form a huge colloidal polymeric molecular group. In this colloidal polymeric molecular group, all water molecules are closely combined with pollutants through chemical bond connection and charged particle electrical adsorption. This combination makes water molecules because of all The external connection chemical bonds and electrical adsorption gaps are occupied by water molecules and other pollutant molecules and lose all activity and the ability to combine with other substances. Even if forced aeration and oxygen introduction are used, oxygen cannot be dissolved in water, and pollution Molecules cannot be directly oxidized and decomposed because all the external chemical bonds and electrical adsorption gaps are occupied by water molecules and other pollutant molecules.

This huge colloidal polymer cluster permeates the entire water area, causing the entire water area to lose all its dissolved oxygen capacity, and the self-purification ability of the water area completely disappears.

The use of chemical agents can only temporarily remove the connection between some pollutants and the water, but these agents form a new connection with the water, and also do not create a space for oxygen to dissolve in the water, so such waters can only become more and more polluted. Serious, the result of using chemical means to control and pollute more
