Description
Technical Field
The invention belongs to the field of solar energy, and particularly relates to a solar photo-thermal power generation sewage treatment device.
Background
The environmental protection is a problem which is commonly concerned by all countries at present, because the natural ecological environment of the world is damaged in different degrees at present, possible mischief is gradually shown, the human health is worsened, the economic construction is slowed down, the energy consumption of the existing sewage treatment equipment is reduced, the treatment method of the sewage treatment equipment causes secondary pollution such as nondegradable and the like, therefore, the inventor designs the sewage treatment equipment which is purely natural and does not need energy consumption, utilizes natural solar energy and natural filter media, can effectively treat domestic sewage, industrial wastewater and other industrial equipment in urban areas, avoids the sewage and pollutants from directly flowing into water areas, and has important significance for improving the ecological environment, improving the urban grade and promoting the economic development.
Photovoltaic power generation is a technology of directly converting light energy into electric energy by using the photovoltaic effect of a semiconductor interface. The solar energy power generation system mainly comprises a solar panel, a controller and an inverter, and the main components of the system are electronic components. The solar cells are connected in series and then are packaged and protected to form a large-area solar cell module, and then the photovoltaic power generation device is formed by matching with components such as a power controller and the like. An inverter is a device that converts direct current electrical energy into alternating current (typically 220V,50Hz sine wave). The photovoltaic inverter consists of an inverter bridge, control logic and a filter circuit, and can stabilize photovoltaic voltage and ensure normal operation of equipment.
In the last decade, attempts have been made to produce water filtration membranes by electrospinning techniques, the main goal being high flux, low resistance microfiltration or ultrafiltration membranes. Compared with the traditional membrane technology, the membrane with the nanofiber structure prepared by electrostatic spinning has the advantages of controllable pore diameter, high porosity, good pore connectivity and high flux. In addition, the electrostatic spinning fiber membrane prepared from the specific ligand material has the characteristics of conventional filtration and separation, and also has the property of an affinity membrane.
Soy protein fiber may be referred to as a "green fiber" of the new age. The main raw material of the soybean meal is soybean meal from the nature, the raw material quantity is large, the soybean meal has reproducibility, and the resource is not subjected to predatory development. The soybean protein fiber production process has no environmental pollution, and the soybean protein fiber production process has no toxicity of the supplementary material and the assistant, most of the assistant and the semi-finished fiber may be recovered for reuse, and the residue after protein purification may be used as feed.
The peanut shells are common wastes, and are ground into powder for chemical treatment, so that the high-quality artificial wood cane is formed, can be used for manufacturing various delicate furniture and appliances, and has strong adsorbability. The coconut shell activated carbon is prepared by using high-quality coconut shells as raw materials and carrying out fine processing through a series of production processes. The coconut shell activated carbon is black in appearance, granular, developed in pores, good in adsorption performance, high in strength, easy to regenerate, economical, durable and the like. The PLA fiber is a synthetic fiber prepared by using starch such as corn, wheat and the like as raw materials, converting the starch into lactic acid through fermentation, polymerizing and spinning.
The applicant provides a solar sewage treatment device for the first time, which mainly takes natural sedimentation and filtration and is matched with disinfection treatment, thereby solving the problems of more bacteria and the like in natural sewage treatment.
