Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] Such as figure 1 As shown, after the wastewater is pretreated in the early stage, the content of pollutants such as nitrogen, phosphorus and organic matter in the wastewater body is reduced to a certain standard. When the waste water 1 flows through the hard substrate 2 constructed of biological ceramsite in the deep pool, a certain negative pressure is generated, and the air quickly enters the waste water body, which greatly increases the dissolved oxygen content in the waste water body.

[0022] When the potential energy of the wastewater body is converted into kinetic energy, the water body collides strongly with the hard bottom substrate 2, and the wastewater undergoes reoxygenation for the second time. The waste water is in contact with the aerobic microorganisms attached to the biological ceramsite, and the organic matte...

Abstract

The invention relates to an aerobic treatment method of deep-pool and shallow artificial wetland wastewater. According to the method, oxygenation is realized in a wastewater falling process; reoxygenation is carried out by converting potential energy into kinetic energy; degradation of aerobic microorganisms is carried out by utilizing a microorganism growth environment of bottom substrates of a deep pool; adsorption removal is carried out by utilizing actions of substrates in different layers of an artificial wetland; and wastewater deep treatment is realized by utilizing the absorption action of large-biomass plants. A deep-pool and shallow artificial wetland disclosed by the invention comprises the deep pool, a shallow, an S-shaped waterproof wall body and the substrates; the S-shaped waterproof wall body is positioned between the deep pool and the shallow; biological ceramsite, which is hard in substrate, large in particle diameter and high in porosity, is adopted as the substrates at the bottom of the deep pool; and the shallow is constructed by different substrates and plants at the front end of the deep pool. By means of aerobic treatment of the deep-pool and shallow artificial wetland wastewater, the wastewater treatment operation cost can be obviously reduced; the wastewater treatment efficiency and the wastewater treatment effect are increased; and organic unification of aerobic treatment and ecological treatment is realized.

Description

technical field [0001] The invention relates to an aerobic treatment method for artificial wetland wastewater in deep pools and shallows, belonging to the technical field of water treatment. Background technique [0002] The shortage of water resources and water pollution directly affect people's industrial and agricultural production and life, and the research and development of wastewater treatment processes and methods has been in a continuous process of advancement. Wastewater treatment technology has been developed on a large scale and widely used. According to different types and properties of wastewater, physical methods, chemical methods, and biological methods are generally used, or a combination of multiple processes. With the continuous improvement and development of wastewater treatment process or technology, the wastewater treatment process of constructed wetland has carried out innovation and technological innovation to varying degrees on the basis ...
