Problems solved by technology

[0004] After continuous research and testing by the applicant, it is found that the existing constructed wetlands for sewage treatment have the following technical problems: 1) After the constructed wetlands are completed, the places on the constructed wetlands close to the sewage water source have high humidity and heavy decontamination burden, It is not conducive to the growth of water storage cells and root length of sphagnum moss, and as time goes by, it reduces the decontamination ability of the constructed wetland near the sewage water source; 2) On the other hand, the places far away from the sewage water source , its decontamination ability cannot be brought into full play, resulting in a waste of resources

Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with accompanying drawing and specific embodiment:

[0021] Such as Figure 1-4 As shown, an urban domestic sewage treatment system based on sphagnum moss includes a pretreatment system 1, a first-level constructed wetland 2, and a second-level constructed wetland 3 arranged in sequence according to the flow direction of domestic sewage. The first-level constructed wetland 2 is used to purify the For the sewage discharged from the pre-treatment system, the secondary constructed wetland 3 is used to purify the sewage discharged from the primary constructed wetland. The pre-treatment system 1 includes a solid waste recovery pool 10 and sewage pipes 11 arranged in sequence from top to bottom, Filter screen 12, sewage treatment tank 13, described filter screen 12 is inclined to set, and described sewage pipe 11 spouts are positioned at the top of the higher end of filter screen, and described solid waste...

Abstract

The invention discloses an urban domestic sewage treatment system based on sphagnum moss, which includes a pretreatment system, a first-level artificial wetland, and a second-level artificial wetland arranged in sequence according to the flow direction of urban domestic sewage. The sewage discharged from the treatment system, the second-level constructed wetland is used to further purify the sewage discharged from the first-level constructed wetland. The pre-treatment system includes a solid waste recovery tank and sewage pipes, filters, sewage Processing pool. The urban domestic sewage treatment system based on sphagnum moss of the present invention can promote the growth of sphagnum moss water storage cells, and can efficiently utilize resources, thereby fully exerting the decontamination capabilities of sphagnum moss and filter materials.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a peat moss-based urban domestic sewage treatment system. Background technique [0002] Constructed wetland is a ground similar to swampland that is artificially constructed and operated under control. Sewage and sludge are distributed to the artificially constructed wetland in a controlled manner. When sewage and sludge flow in a certain direction, they are mainly used It is a technology for treating sewage and sludge through the triple synergy of physics, chemistry and biology of soil, artificial medium, plants and microorganisms. [0003] Sphagnum moss is also known as sphagnum moss and moss. There are transparent dead cells in the leaves of sphagnum moss, namely water storage cells. The water storage cells of sphagnum moss can store a large amount of water and can absorb water up to 20 times its own weight. The water storage capacity is higher than that of other moss...
