Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] see figure 1 , figure 2 and image 3 A rainwater distribution collection and treatment system for urban living quarters is shown, including an inlet pool 2 connected to a rainwater collection culvert 1, an initial rainwater storage pool 4 adjacent to the inlet pool, and a clear water pool 6 adjacent to the initial rainwater storage pool , a grid 7 is arranged in the rainwater collection culvert 1, which is used to intercept and remove large-sized solid objects transported with the runoff;

[0024] The first artificial wetland 3 is provided above the initial rainwater storage pond 4, and the second artificial wetland 5 is provided above the clear water pond 6; the rainwater of the urban living quarters collected by the rainwater collection culvert 1 flows into the water inlet pond 2, and passes through the first artificial wetland 5. The constructed wetland 3...

Abstract

The invention discloses a city life residential area rainwater shunting, collecting and treating system. The city life residential area rainwater shunting, collecting and treating system comprises a water inlet pond, an initial rainwater storage pond and a clean water pond and is characterized in that a first constructed wetland is arranged above the initial rainwater storage pond and a second constructed wetland is arranged above the clean water pond; the rainwater of the city life residential area collected by a rain sewage collecting conduit flows into the water inlet pond, flows into the initial rainwater storage pond after passing through the first constructed wetland and then flows into the clean water pond after passing through the second constructed wetland. By using the system disclosed by the invention, the initial rainwater and the later rainwater of the residential area are shunted and treated; a rainwater purification facility and a storage facility are constructed with one blow the other so that the space usage of the treatment process is reduced; the inferior rainwater in the initial rainwater storage pond is discharged into the second constructed wetland to be continuously treated by using a time slot without rain after the rain stops so that the inferior rainwater is recycled after reaching the city nondrinking water quality; and the system has the advantages of investment conservation, low operation cost and easiness in operation and management.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a rainwater distribution collection and processing system in urban living quarters. Background technique [0002] With the continuous investment and construction of urban environmental infrastructure, the continuous improvement of the operating mechanism and the acceleration of the construction of sewage plants, the amount of urban sewage treatment has increased year by year, the treatment rate has continued to increase, and the proportion of point source pollution in urban water environment problems has gradually decreased. , and the proportion of non-point source pollution is increasing day by day, posing a serious threat to urban water systems. [0003] Non-point source pollution control technology is currently a research hotspot, aiming at problems such as high proportion of impermeable area in urban living quarters, short runoff flow, prone to fl...
