Micro-oxygenation on-line monitoring automatic control system

Abstract

The invention relates to a micro-oxygenation on-line monitoring automatic control system which comprises a water quality monitoring system, a data processing system and a micro-oxygenation aerating system, wherein the water quality monitoring system is arranged in a water body to be restored, and used for performing on-line in-situ detection on changes of water quality indexes, converting the detection values into an electric signal in real time and transmitting the electric signal to the data processing system; the data processing system is used for comparing the value measured by the water quality monitoring system with the system set value, determining whether oxygen supply is needed, giving out the aeration amount required by the water body of the corresponding region if the oxygen supply is needed, and meanwhile, transmitting an electric signal to start the micro-oxygenation aerating system; and the micro-oxygenation aerating system is used for controlling the amount of air entering the water body by using an electric control valve on the air pipe, thereby performing aeration. The micro-oxygenation on-line monitoring automatic control system can adopt different aeration intensities according to different water qualities.

Description

【Technical field】 [0001] The invention belongs to the technical field of environmental protection, and specifically refers to a micro-oxygenation online monitoring and automatic control system. 【Background technique】 [0002] With the development of social production, rivers all over the world are facing different degrees of pollution from industry, agriculture, life and other aspects. Since the 1950s and 1960s, developed countries such as Europe and the United States have begun to consider various methods to solve the increasingly serious problem of river pollution. Among them, river aeration technology, as a river pollution control technology with low investment and quick results, is preferred in many countries. [0003] According to the water quality improvement requirements of the aerated river course (such as eliminating black odor, improving water quality, restoring ecology, etc.), river channel conditions (including water depth, flow velocity, channel cross-section s...

Problems solved by technology

[0005] However, in practice, river aeration technology is mostly used as a temporary or emergency measure in the practice of river pollution control, and there are two main reasons for restricting its application: 1. This technology will fundamentally be a kind of water body The passive treatment technology adopted after pollution can also be said to be a technology that pollutes first and then treats it, or a technology that treats the symptoms but not the root cause

Its control effect depends on the existence and size of external pollution sources; 2. The water volume and water quality of external pollution in the river course vary greatly, which directly affects the effect of aeration
