Problems solved by technology

[0004] However, there are still many problems in the constructed wetland technology at present: 1. The treatment load is low; 2. The treatment effect is poor, which can only meet the national standard Class B standard; 3. The phosphorus removal effect is poor; Short life; 5. Freezing in winter, unable to operate normally; 6. Surface overflow has adverse effects on the environment

Embodiment Construction

[0025] Refer to the attached Figure 1-2 A wetland system for sewage treatment according to an embodiment of the present invention is described. figure 1 A schematic structural view of a wetland system for sewage treatment according to an embodiment is shown, including: a sewage pretreatment device, a sewage water delivery and distribution device 7, a wetland plant bed 8, an effluent collection device 9, and the sewage passes through the sewage pretreatment device After pretreatment, it enters the sewage water delivery and distribution device 7, then enters the wetland plant bed 8 for treatment, and finally enters the effluent collection device 9. The wetland plant bed 8 includes wetlands arranged from top to bottom Plant 1 , low permeability matrix 13 , high permeability matrix 16 , the permeability of the high permeability matrix 16 is greater than the permeability of the low permeability matrix 13 .

[0026] The wetland plant bed 8 also includes a sealing layer 12 configur...

Abstract

The invention provides a functional accurate wetland system which comprises a sewage pretreatment device, a sewage conveying distributing device, a wetland plant bed and a water outlet collecting device. Sewage is pretreated through the sewage pretreatment device and then enters the sewage conveying distributing device, then enters the wetland plant bed to be treated, and finally enters the water outlet collecting device. The wetland plant bed comprises wetland plants, a low-permeability substrate and a high-permeability substrate which are arranged from top to bottom. The permeability of the high-permeability substrate is larger than that of the low-permeability substrate.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a functional precision wetland system. Background technique [0002] Constructed wetland refers to the ground similar to swampland that is artificially affected, constructed and controlled. Sewage and sludge are distributed to the artificially constructed wetland in a controlled manner. During the flow of sewage and sludge in a certain direction, the main It is a technology to treat sewage and sludge by using the physical, chemical and biological synergy of soil, artificial medium, plants and microorganisms. While treating sewage, artificial wetlands can beautify the environment, adjust the local climate, and increase biodiversity. It has the reputation of "the kidney of the earth". [0003] Since the rapid development of constructed wetlands in the 1970s and 1980s, various wetlands have been used to treat a large number of different wastewaters all over the world. At present, m...
