Embodiment

[0045] An integrated composite three-dimensional constructed wetland system is constructed. The bed body of the integrated composite three-dimensional constructed wetland system is a brick-concrete structure treated with waterproofing. The upper part of the internal space is a surface flow pool and the lower part is a subsurface flow pool; the surface flow The pool and the subsurface flow pool are filled with gravel as the surface flow pool matrix 10 and the subsurface flow pool matrix 9 respectively, and the filling thicknesses are 50 cm and 100 cm, respectively. The surface flow pool is planted with reeds as water purification plants 2, and the two ends of the surface flow pool are respectively provided with a water inlet distribution pipe 1 and a surface flow collection pipe 3, and the water inlet distribution pipe 1 and the surface flow collection pipe 3 are respectively A water distribution hole 11 and a water collection hole 12 are provided, and the horizontal position of...

Abstract

The invention provides an integrated composite stereo constructed wetland system and a sewage processing method. The system comprises a wetland bed body possessing water-resisting function, and a surface flow pool and a subsurface flow pool which are constructed in the internal space of the wetland bed body; water-purification plants are grown on the surface flow pool, and also the surface flow pool is provided with a water inlet device; the surface flow pool and the subsurface flow pool are in connection via a reclaimed-water collection distribution device; and the subsurface flow pool is provided with a clean-water discharge device. The upper part of the internal space of the wetland bed body is the surface flow pool, and the lower part is the subsurface flow pool. The surface flow pool and the subsurface flow pool are respectively filled with a surface-flow pool matrix and a subsurface-flow pool matrix, the surface-flow pool matrix is used to fix the root of the water-purification plant and adsorb aerobic and facultative microbes, and the subsurface-flow pool matrix is used to adsorb hypoxic and anaerobic microbes and denitrifying bacteria. The provided sewage processing method employs the above wetland system for purifying sewage. The wetland system possesses the advantages of being small in land occupation area, good in discharged water quality and the like.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an integrated composite three-dimensional artificial wetland and a sewage treatment method. Background technique [0002] In the process of urban development in my country, the municipal sewage treatment system collects the sewage within the designated sewage discharge range, and transports it to the sewage treatment plant for centralized treatment by the urban sewage pipe network. However, the development of relatively remote areas such as rural areas in my country is still relatively lagging behind. At present, the treatment of domestic sewage in these places has not been well resolved. However, it will cost a lot of money to collect all the domestic sewage in these places to sewage treatment plants. Construction costs of sewer pipes. At the same time, today's society is facing the problem of water shortage, and the recycling and reuse of sewage will inevit...
