Carbon-neutralized sewage treatment solar heat gathering reactor

Abstract

The invention relates to the technical field of sewage treatment, and discloses a carbon-neutralized sewage treatment solar heat gathering reactor which comprises a reactor body; the reactor body is divided into a first reaction layer and a second reaction layer which are arranged up and down by arranging a biological filler grating plate, the first reaction layer is arranged above the second reaction layer, and the first reaction layer is filled with a first biological filler to form a microalgae community, and the second reaction layer is filled with a second biological filler to form an efficient flora. The method has the characteristics of economy, high efficiency, simplicity, feasibility and carbon emission reduction.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a carbon-neutral solar heat concentrating reactor for sewage treatment. Background technique [0002] At present, our country is facing very serious water pollution environmental problems. Traditional water pollution treatment methods mainly use physical and chemical methods to purify water bodies. New types of waste water and sewage are particularly important. [0003] Traditional water pollution biological treatment methods mainly include activated sludge method, biological contact oxidation method, oxidation ditch process, A / O process, SBR process, MBR process, etc. The main problems of these traditional treatment methods are: 1. Traditional The sewage treatment plant is not only an important facility for pollutant removal, but also a large energy-consuming and carbon-emitting entity. It is estimated that by 2030, the greenhouse gas emissions of the entire sewage tre...

Problems solved by technology

[0003] Traditional water pollution biological treatment methods mainly include activated sludge method, biological contact oxidation method, oxidation ditch process, A / O process, SBR process, MBR process, etc. The main problems of these traditional treatment methods are: 1. Traditional The sewage treatment plant is not only an important facility for pollutant removal, but also a large energy-consuming and carbon-emitting entity. It is estimated that by 2030, the greenhouse gas emissions of the entire sewage treatment industry in China will reach 2.95% of the national greenhouse gas emissions; 2. Traditional sewage treatment technology The process is long, the floor area is large, the construction cost is high, and the power consumption is high; 3. The denitrification reaction time is long, the proliferation of bacteria is slow, and it is easily affected by the low temperature environment, and the denitrification efficiency decreases; 4. The process is relatively complicated and the operation Other steps are required in the process, which increases operating costs and secondary pollution; therefore, the sewage treatment industry and technology need to change direction, technological innovation, and the realization of low-carbon or even zero-carbon sewage treatment is imminent
