Embodiment Construction

[0022] Figure 1 shows the overall situation of the system of the present invention, which is also an embodiment. It can be seen from Fig. 1 that the reservoir 3, the wetland clean water pool 4 and the sewage well 2 constitute underground sewage and rainwater collection and treatment structures. The sewage well 2 can also adopt the existing sewage collection well, and the domestic sewage enters the well and enters the reservoir 3 after preliminary sedimentation treatment. In the depths, the reservoir 3 filters and treats the sewage and raises it to the constructed wetland 1 by the water pump and the pump. The processing scale is 10m 3 / h, covers an area of ​​50m 2 , a constructed wetland of this size can irrigate an area of ​​about 800m strawberry gardens 2 . The sewage treated by the artificial wetland 1 can be used for watering the land and greening. After the rainwater flows into the artificial wetland 1, it also enters the wetland clear water pool 4 together with the tr...

Abstract

The invention relates a collection and treatment system of domestic sewage and rainwater in residential community, which is used for roof plantation. The invention includes construceted wetland, underground sewage and rainwater collection and treatment structure, roof irrigation device and planting soil layer. The pinciple of the underground sewage and rainwater collection and treatment structure seperated into reservoir, wetland clear water tank and sewage well, is: firsti, the sewage after treatment flows through pipes into the reservoir which has a pump arranged on its base; second, the sewage is lifted by the pump to constructed wetland which filters the sewage; then, the filtered sewaged flows into wetland clear water tank which also has a pump arranged on its base and has pips connected with the roof. Theroof irrigation device includes a plurality of roof clear water boxes arranged on the roof, outlet pipes, and drip irrigation pipes. The planting soil layer is layed averagely on the roof in a manner that a soil layer with a soil layer depth of 10cm and a soil bulk density of 120kg/m2, is layed on a geotextile layer layed on a water storage board which is layed on a thermal insulation board.

Description

technical field [0001] The invention belongs to the field of environmental protection. In particular, it relates to a system for collecting and treating domestic sewage and rainwater in residential areas for roof planting. Background technique [0002] The domestic sewage in residential areas flows into sewage treatment plants or rivers through the drainage system. What is discharged into the river will pollute the river water, as well as the environment and the surface through which the sewage flows. At the same time, it also pollutes the ambient air and easily produces harmful flies. In recent years, the treatment of domestic sewage in residential areas has also been reused after comprehensive treatment, such as Chinese Patent No. 200410023763. Such as Chinese patent application 97109845.X, there are other processing methods, not listed one by one. These domestic sewage treatment methods have their own advantages and different tendencies. Basically, biological carriers ...
