Device for controlling harmful gas in pipeline through micro-nano bubbles

Abstract

The invention discloses a sewage pipeline harmful gas treatment device which comprises a box body and further comprises a solar power supply module arranged outside the box body in a connected mode and a central control module arranged inside the box body in a connected mode, and the central control module is connected with a gas pump, a gas detection device and a micro-nano aeration module. The solar power supply module is used for providing stable working voltage for the central control module, the gas pump, the gas detection device and the micro-nano aeration module; the gas pump is used for ventilating and aerating; the gas detection device is used for detecting the concentration of harmful gas in the sewage pipeline and sending the detected concentration of the harmful gas to the central control module; the micro-nano aeration module is used for micro-nano aeration; the central control module is used for controlling the micro-nano aeration module and the gas pump to work accordingto the concentration of the harmful gas received from the gas detection device. The invention further discloses a sewage pipeline harmful gas treatment method. Micro-nano aeration is carried out on sewage in the sewage pipeline to treat the harmful gas in the sewage pipeline.

Description

Technical field [0001] The invention belongs to the technical field of environmental protection, and relates to pipeline environmental treatment, in particular to a harmful gas control device that combines ventilation and adding micro-nano bubble water. Background technique [0002] Urban sewage pipe network is an important part of urban public facilities and an important guarantee for human health and water environment safety. However, in recent years, there have been more and more problems with sewage pipes, and the most discussed is the influence of harmful gases in sewage pipes. Due to the long residence time of sewage in the pipeline, an anaerobic environment will be formed in the pipe, and a large number of biofilms will grow on the pipe wall, and the anaerobic microorganisms in the biofilm will produce a large amount of toxic and harmful gases in the drainage network. The sulfate content in urban sewage is 40-200mg / l, and the sulfate reducing bacteria in the pipe network ...

AI Technical Summary

Problems solved by technology

When the method of injecting air is used, the O that can be transported into the pipeline 2 The content is limited and the utilization rate is low, while the injection of O 2 When the method is used, there is a possibility of fire hazard, and the safety is low.
