Modular sewage treatment device based on constructed wetlands and sewage treatment method

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. ...

AI Technical Summary

Problems solved by technology

[0005] In view of the above problems, the purpose of the present invention is to provide a modular sewage treatment device and sewage treatment method based on constructed wetlands, to solve the current problems in the prior art, such as long construction period, slow start-up of wetland systems, and construction problems in traditional constructed wetlands. High quality requirements, large footprint, serious matrix clogging, and poor management and maintenance performance
