A mud-water interface physical and chemical control system for in-situ restoration of landscape water bodies

Abstract

The invention relates to the field of landscape water purification, and provides a sludge-water interface physico-chemical regulation and control system for landscape water in-situ repairing. The system comprises a landscape water simulation system (1), an electric control system (2) and a computer control system (3), wherein the landscape water simulation system (1) is connected with the electric control system (2) through a data collection line (4), the electric control system (2) is connected with the computer control system (3) through a data control line (5), the landscape water simulation system (1) comprises a tank body (6), a sludge level meter (7), an ORP electrode (8), a height regulator (9), a nano microporous aerator (10) and a frequency-variable fan (11), the sludge level meter (7), the ORP electrode (8), the height regulator (9), the nano microporous aerator (10) and the frequency-variable fan (11) are connected with the electric control system (2) through a data collection line (4), and the nano microporous aerator (10) is connected with the frequency-variable fan (11) through an air conveying pipe (13). The physico-chemical regulation and control system provides essential technical support for building and mastering aeration oxygenation amount and sludge pollutant release law and practical engineering application of civic landscape water in-situ repairing.

Description

technical field [0001] The invention relates to the field of landscape water body purification, in particular to a mud-water interface physicochemical control system suitable for in-situ restoration of urban landscape water bodies. Background technique [0002] In recent years, with the acceleration of urbanization and the improvement of people's living standards, urban landscape water bodies, including urban inland rivers, lakes and other surface water bodies, have been seriously polluted. The urban landscape water body is very closely related to the living environment, and has important aesthetic value, ecological function and economic significance. Therefore, strengthening the pollution control of urban landscape water bodies has become one of the research hotspots in recent years, especially the control of the main inducing factors nitrogen and phosphorus. [0003] For the control of endogenous nitrogen and phosphorus in sediment, a large number of research reports have...

Problems solved by technology

[0006] The purpose of the present invention is to aim at the in-situ repair technology of urban landscape water body - artificial reoxygenation technology in the process of using, because the aeration rate of the mud-water interface and the release law of nutrients such as nitrogen and phosphorus in the bottom mud are not clear, resulting in unnecessary In order to solve the problem of resource waste, develop a scientific, simple and practical mud-water interface physical and chemical control system for in-situ restoration of landscape water, so as to establish and control the amount of aeration and oxygenation and the release of sediment pollutants Provide the necessary technical support for the actual engineering application of regularity and subsequent in-situ restoration of urban landscape water bodies
