Landscape energy-saving-type water treatment combined system in residential area

Abstract

The invention discloses a landscape energy-saving-type water treatment combined system in a residential area, and belongs to the technical field of comprehensive utilization of resources. The system has integrated functions of a plant carbon source soaking pond, a vertical flow treatment pond, a horizontal underflow treatment pond, an ultraviolet disinfection pond and a clean water pond, wherein carbon released by the soaking of plant residues is taken as an additional carbon source and enters the vertical flow treatment pond along with sanitary wastewater so as to realize denitrification and dephosphorization; then the denitrification and the dephosphorization are further carried out in the horizontal underflow treatment pond to remove the excessive organic carbon pollution caused by the soaking of the plant carbon source; next, the treated wastewater is disinfected by ultraviolet rays and enters the clean water pond. According to the system disclosed by the invention, the problems in the prior art that the water treatment wetland system is high in cost, large in land occupation, difficult in running, high in cost due to the direct addition of the additional carbon source or easy to block and the like during the construction of the residential area are solved. The system disclosed by the invention is reasonable in process design, convenient to operate and easy to maintain, and can realize the unification of water treatment and recycling, landscape, land saving, energy saving and sustainable development in the residential area, thereby having a good popularization and application value.

Description

[0001] technical field [0002] The invention relates to the technical field of comprehensive utilization of resources, in particular to a combination system for treating reclaimed water in a landscape energy-saving residential area. [0003] Background technique [0004] In the southern part of my country, the reclaimed water source in the community is large and stable, but it has not been fully utilized due to problems such as high investment in treatment equipment, complicated operation and maintenance, and lack of professional knowledge and skills for property personnel. A large amount of reclaimed water from residential buildings is imported into the municipal sewage treatment system, which not only wastes reclaimed water resources but also increases the amount of municipal sewage treatment and investment. [0005] In addition, with the development of greening construction in urban and rural areas and communities, a large number of plant residues such as litter and le...

AI Technical Summary

Problems solved by technology

Although the constructed wetland treatment method has traditional advantages, it also has problems such as large footprint and unstable operation effect, and for reclaimed water with a low carbon-to-nitrogen ratio, the treatment effect of the constructed wetland is not high, and an additional carbon source is required In order to achieve better nitrogen and phosphorus removal effect

The addition of liquid carbon sources requires a large amount of economic investment, and direct addition of plant materials will cause problems such as blockage and difficult restoration of the wetland matrix.
