Floating wetland system for efficiently purifying sewage

Abstract

The invention relates to a floating wetland system for efficiently purifying sewage. The floating wetland system comprises a floating unit, and a wetland unit, a photovoltaic unit, a detection unit, a wireless communication unit and an aeration unit which are all mounted on the floating unit, the wetland unit comprises a gravel layer, an activated carbon adsorption layer, a microbiological treatment layer, a sandy soil layer and a plant layer which are sequentially arranged from bottom to top; the floating unit comprises a floating box body used for floating in water and an anchor, and a water inlet hole is formed in the floating box body; the detection unit is used for detecting one or more of dissolved oxygen, temperature and pH in the water body; the wireless communication unit is used for sending the detection data to the server; an aeration pipe of the aeration unit is mounted between the bottom of the floating box body and the gravel layer; the detection unit and the aeration unit are electrically connected with the photovoltaic unit. According to the system, the solar module is adopted to provide power for aeration and detection, the aeration device is used for aeration to provide oxygen, the purification capacity is high, maintenance is convenient, and real-time and accurate detection results can be provided.

Description

technical field [0001] The invention relates to a sewage purification system, in particular to a floating wetland system for efficiently purifying sewage. Background technique [0002] The key to the purification of black and odorous water is to remove a large number of dissolved pollutants in the water, reduce the chemical reaction conditions of these pollutants, increase the dissolved oxygen content in the water, thereby increasing the transparency of the water and improving the quality of the water. The main purification mechanisms are physical, chemical and biological. The biological method will not cause secondary pollution. It not only has the function of environmental purification, but also has a landscape effect. However, a single biological method cannot economically and effectively purify black and odorous water bodies. Therefore, artificial wetlands and ecological floating bed systems with ecological restoration functions It is more widely used in practical appli...

Problems solved by technology

[0004] However, the existing floating wetlands are basically passive in the treatment of sewage, the treatment effect is not good, and the external influence is relatively large

And because it is in the water body, it is difficult to monitor, and it is impossible to grasp the treatment situation in a timely and accurate manner.
