Algae-mosquito-duckweed joint control device based on dry-wet effect and control method thereof

Abstract

The invention discloses an algae-mosquito-duckweed joint control device based on a dry-wet effect and a control method thereof. The algae-mosquito-duckweed joint control device is characterized by comprising a sewage draining exit identification unit, a lifting mechanism, a hierarchical control unit and a central control unit, and the hierarchical joint control unit realizes hierarchical blockingof sewage draining exit pollutants and directional inactivation of algae-mosquito-duckweed; the central control unit is used for collecting information and sending out related instructions, and algae,mosquitoes and duckweed combined control of the sewage draining exit and water quality purification of the sewage containing water body are achieved. Compared with the prior art, the device has the advantages of dry-wet separation and directional inactivation of algae, duckweed and other pollutants, purification and improvement of the water quality of sewage, simple structure, energy saving, environmental protection, good practicability, no secondary pollution, purification effect on rainwater runoff pollution, and effective prevention of the black and odorous problem of urban water caused byrunoff pollution.

Description

technical field [0001] The invention relates to the technical field of garbage treatment of rainwater pipes, in particular to a combined control device for algae and mosquitoes based on the dry-wet effect and a control method thereof. Background technique [0002] One of the main pollution sources of rivers and other sewage receiving bodies is the rainwater and the pollutants carried by the coastal communities, including the pollutants carried by the surface runoff of the rainwater and the laundry sewage entering the rainwater pipe network due to the mixing of rain and sewage. When the rain pattern is small or in the dry season, laundry sewage and surface runoff enter the rainwater pipe network at the same time, the flow of water in the rainwater pipe is small, the flow rate is low, and pollutants are easily deposited in the pipe; when the rain pattern is large, short-term instantaneous rainwater will impact the community The sediment accumulated in the rainwater pipe networ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to design a joint control device and control method based on dry and wet effects for algae and mosquito sputum based on the deficiency of the prior art, and adopt a joint control device for blocking pollutants in stages to realize automatic control of algae at the sewage outlet The dry and wet separation and directional inactivation of pollutants such as pollutants have greatly purified and improved the water quality of the sewage receiving body. The structure is simple, energy-saving and environmentally friendly, the construction cost is low, and the operation and maintenance are convenient. No secondary pollution, has a purifying effect on rainwater runoff pollution, and effectively prevents the problem of black and odorous urban water bodies caused by runoff pollution
