Abstract

The invention provides a solar thermal energy turbine blast aeration oxygenation sewage treatment system, which comprises a first tank body, a second tank body, a solar energy collecting device, a heat dissipation device, a first turbine, a rotary shaft, a blast device and a sewage biological treatment tank, wherein the solar energy collecting device is connected with the heat dissipation device;the heat dissipation device is arranged in the second tank body; the second tank body is arranged in the first tank body; a second tank body air outlet hole is formed in the top end of the second tankbody; a second tank body air inlet hole is formed in the bottom end of the second tank body; the second tank body air outlet hole is communicated with the second tank body air inlet hole through a first air flow channel; the rotary shaft is arranged on the first tank body along the axial direction of the first tank body in a rotary manner; the first turbine is sleeved on the rotary shaft; the first turbine is arranged at the position of the second tank body air outlet hole; the blast device is arranged at the top end of the first tank body; the input end of the blast device is connected withthe rotary shaft; and the output end of the blast device is connected with the sewage biological treatment tank through a pipeline.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a solar thermal energy turbine blast aeration oxygenation sewage treatment system and method. Background technique [0002] Small and medium-sized railway stations, expressway service areas and toll stations, transmission substations, oil (gas) pressurization stations, rural areas, islands, border posts, some scenic spots and other sewage discharge sites are often scattered in remote or suburban areas along the line. The office and domestic sewage generated in these locations cannot be connected to the local urban municipal sewage treatment plants, or it is economically unreasonable to collect and transport sewage to sewage plants, and usually adopts the method of self-treatment. [0003] Anaerobic biological sewage treatment technology has been used in small and medium-sized railway stations. Although it saves energy, there are problems such as long residence time of se...

Problems solved by technology

According to research literature, under normal atmosphere, light intensity and temperature conditions, the highest photoelectric conversion rate of domestic commercial solar panels is 15%-21%. The output power is generally between 55% and 85%. Due to the limitation of power factor, the energy efficiency will be further reduced. The oxygen supply device driven by electric energy needs to be equipped with a large area of ​​photovoltaic panels, and the unit price of photovoltaic cells is high, and the battery life is short. , resulting in a large investment in equipment, such as the cancellation of the photovoltaic subsidy policy, the economy is lower
