Embodiment

[0033] Such as figure 1 Shown, the present invention is made of two parts of outer nest 1 (for setting activated sludge tank) (area 40cm * 40cm, height 40cm) and inner nest 2 (area 35cm * 35cm, bottom relative elevation 25cm).

[0034] The outer nest 1 is provided with a water inlet pipe 3 and an aeration pipe 4 . The outlet of the water inlet pipe 3 is set inside the activated sludge tank, and the aeration tube 4 is placed at the bottom of the activated sludge tank.

[0035] In the inner nest 2, the support plate is arranged at the bottom of the inner nest 2, and several through holes (area 1cm×1cm) are arranged on the support plate, and the inner wall of the inner nest 2 is provided with a water collection weir 7 (relative to the support board, weir height 25cm).

[0036] The invention organically combines activated sludge, biological filter layer, landscape plants 8 and ornamental fish into one body. The bottom of the outer nest 1 is the activated sludge area, which is t...

Abstract

The invention relates to an activated sludge-bio-filter bed-landscape ecology sewage treatment method and system. In order to solve problems that the landscape effect is poor, peculiar smell is serious, a large amount of sludge is produced and the like in the wastewater treatment process, an activated sludge-bio-filter bed-landscape ecology sewage treatment method and system are developed in combination of activated sludge, a bio-filter bed, a landscape wetland and the like in the water treatment technology. The method and the system are used for treating domestic wastewater, organic wastewater, surface polluted water and the like and have the advantages of simple structure, low operation cost and high removal rate of ammonia, nitrogen and COD (chemical oxygen demand), and organic combination and advantage complementation of landscape ecology and a wastewater treatment technology are achieved through ways such as plant matching and selection, landscape construction and the like.

Description

technical field [0001] The invention relates to the field of sewage treatment, more specifically, to an activated sludge-biological filter bed-landscape ecological sewage treatment method, and an activated sludge-biological filter bed-landscape ecological sewage treatment system. Background technique [0002] Most domestic sewage treatment projects mainly consider technology and economy in the process of design and construction, and often ignore the harmony and unity with the environment. With the development of science and technology, the progress of society, and the improvement of people's living standards, people's aesthetic level is getting higher and higher, and they pay more attention to the harmony between people and the environment. Today, when green earth and green homes are respected, how to integrate engineering landscape into the field of environmental protection? It is of epoch-making significance to integrate ecologicalization into green homes and build a harmo...
