Abstract

The invention discloses a multistage-series constructed wetland sewage treatment system and method based on solar energy, which are used for multistage biochemical treatment on sewage. The sewage treatment system comprises an A<2> / O treatment device and a constructed wetland treatment system, which are connected in series; the constructed wetland treatment system is formed in such a way that a vertical flow constructed wetland and a horizontal flow constructed wetland are connected in series, and arranged in a shed film photovoltaic solar greenhouse with a ventilation device; an amorphous silicon film solar panel is laid on the outer surface at the top of the shed film photovoltaic solar greenhouse; when sun light energy irradiates the amorphous silicon film solar panel, one part of sun light energy is converted into electric energy, while the other part of sun light energy penetrates the amorphous silicon film solar panel to be used for plant photosynthesis. The sewage treatment system is high in efficiency, and the shed film photovoltaic solar greenhouse meets the illumination and temperature requirements of plants in normal growth in all seasons, achieves the low-cost solar energy generation, and has favorable economic benefits and environmental benefits.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a solar energy-based multi-stage serial constructed wetland sewage treatment system and a method thereof. Background technique [0002] The rural population of our country is huge, and the living environment and quality of the rural areas reflect the overall level of my country's economic development to a large extent. With the implementation of national environmental protection policies and the continuous improvement of residents' living standards and environmental protection awareness, many rural areas are currently vigorously promoting the construction of sewage treatment projects to protect and improve the rural environment. More and more technologies have been applied to rural sewage treatment, mainly including anaerobic digester technology, stabilization pond technology, soil infiltration technology and constructed wetland technology. [0003] Most of the rural ...
