Example Embodiment

[0029]In the following description, for the purposes of illustration, many specific details are set forth in order to provide a comprehensive understanding of one or more embodiments. However, it is clear that these embodiments can be implemented without these specific details.

[0030]In the prior art, the traditional artificial wetland has a long construction period, the wetland system is started, the construction quality requires high, and the surface area is high, and the matrix block is serious, and the management and maintenance performance is proposed. The sewage treatment effect is good, the area is small, and the modular sewage treatment apparatus and sewage treatment method based on artificial wetlands in the construction cycle.

[0031]A specific embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0032]In order to illustrate the modular sewage treatment apparatus based on artificial wetlands provided by the present ...

Abstract

The invention provides a modular sewage treatment device based on an artificial wetland and a sewage treatment method. The modular sewage treatment device comprises a modular artificial wetland system and a pretreatment composite module, the modular constructed wetland system comprises a stepped wetland module main body and a stepped foundation; the stepped wetland module main body comprises at least two wetland modules, a bell and spigot is formed in the top of one end of each wetland module, a spigot is formed in the bottom of the other end of each wetland module, and the adjacent wetland modules are connected in a stepped inserting manner through the bell and spigot and the spigot; the pretreatment composite module comprises a sludge settling chamber, an anaerobic digestion chamber and a water flow storage chamber; a biological filler area is arranged in the anaerobic digestion chamber; and a water outlet of the water flow storage chamber is connected with a bell and spigot on the top layer of the stepped wetland module main body. The problems that a traditional constructed wetland is long in construction period, slow in wetland system starting, high in construction quality requirement, large in occupied area, poor in management and maintenance performance and the like can be solved.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and more specifically relates to a modular sewage treatment device and a sewage treatment method based on an artificial wetland. Background technique [0002] Along with the process of new rural construction, the urbanization rate in rural areas has increased significantly in recent years, and various types of water and sanitation equipment have become popular rapidly. The amount of sewage discharged in rural areas has far exceeded the environmental capacity, resulting in serious deterioration of the rural water environment. [0003] At present, the economic strength of rural areas is still very weak and there is no large-scale sewage collection capacity. As an ecological sewage treatment technology, artificial wetlands have a good reputation in rural areas because of their advantages of low investment, environmental protection, energy saving, and easy maintenance. application prospects. ...
