Embodiment Construction

[0023] In order to make the purposes and technical solutions of the embodiments of the present invention clearer, the technical solutions of the present invention will be described clearly and completely below with reference to the embodiments of the present invention. Obviously, the described embodiments are some, but not all, embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0024] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Using ionizing radiation technology to treat sewage has the advantages of fast reaction speed and complete degradation of pollutants. It does not need to add chemical reagents. Environmental friendliness. Existing ionizing radiation water treatment technologies usually...

Abstract

The invention discloses a sewage treatment device and system.The sewage treatment device can comprise a water conveying pipeline and at least one irradiation source based on a miniature electron source, and the irradiation source is used for generating electron beams or X-rays to irradiate liquid to be treated in the water conveying pipeline so as to purify the liquid to be treated. The irradiation source based on the micro electron source is small in size and can be arranged in a small space; energy is low, and fewer protective measures are needed; and a micro-nano processing technology is adopted, so that the cost is lower, and the application range is wider. The irradiation sources based on the micro electron source can be arranged in an array mode to work in parallel, the processing capacity can be improved, the requirement for irradiation uniformity can be lowered, and the better processing effect is achieved.

Description

technical field [0001] The present application relates to the field of electronic science and technology, and in particular, to a sewage treatment device and system. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical, catering and other fields. There are many kinds of sewage with different properties, complex components, and poor biodegradability. Traditional methods are extremely difficult to treat. Especially the high-concentration and refractory industrial wastewater is one of the major problems in the sewage treatment industry. [0003] Advanced oxidation technology (AOP) is a process of oxidative degradation of pollutants in sewage that cannot be oxidized by common oxidants by generating hydroxyl radicals unde...
