Problems solved by technology

The application of storm runoff control in my country is still limited to some areas of the city, and the scope of application is small, and the application level of planning and design tools supported by advanced technology is low or not applied, resulting in the effect of engineering application is not obvious
At the level of urban planning, there is no specific urban storm runoff management plan aimed at flood control, water quality protection, and landscape comprehensive effects, and comprehensive control of storm runoff is rarely considered in urban master planning

Embodiment Construction

[0027] Specifically is an embodiment

[0028] The following combines the attachment to further explain the present invention.

[0029]See Figure 1 to Figure 8 A green building community shown in rainwater interception system, which is composed of multiple subsystems located in low -potential green areas. The subsystem is composed of the sub -intercepting and penetrating emissions system along the way.

[0030] The sub -interception and penetration system is composed of water inlet pipe 1. Water collection well, water garden A4, water garden B5, filler well 9, water collection well B16, water outlet pipe 17, external water -transmitting filler layer 19 outside the well.

[0031] The water inlet pipe 1 receives the lower left part of the water collection well with an indifferent well cover, and the outlet pipe 17 receives the upper right upper part of the water collection well B16 with an indifferent water well. The top of the filler well 9 with a well 10 is located on the water col...

Abstract

The invention discloses a green rainwater collection and sewage interception system for building districts, which comprises a plurality of subsystems which are serially connected and arranged in a low-altitude greenbelt in a district. Each subsystem comprises a sewage interception infiltration subsystem and route infiltration drainage subsystem. Rainwater flowing in the system is subjected to accumulation, storage, infiltration, detaining and energy dissipation, and amount of thermal rainwater discharge is reduced greatly. When permeating a permeable filling layer, a water-holding garden planting soil layer, a filling layer of the water-holding garden planting soil layer, a filling layer of a filling well and the like outside the system, the rainwater is adsorbed, infiltrated and held, and pollutant carried by the rainwater is removed effectively. Amount and quality of collected water are controlled at the terminal of the system, and the terminal rainwater can be collected for reuse or drained into a municipal rainwater network. In addition, flowing time of the rainwater in drainage is prolonged, urban rainwater flood peaks can be lowered, urban living environment can be beautified, and natural hydrographic cycle balance can be maintained.

Description

Technical field [0001] The present invention belongs to the field of municipal engineering and environmental protection technology, and it involves a green building community rainwater collection sewage interception system. Background technique [0002] Rainwater is an important link in urban water circulation and regional water circulation system, which plays a very critical role in regulating, supplementing regional water resources, and improving the ecological environment.China is currently in the stage of rapid urbanization. With the improvement of urbanization and the rapid development of the economy, the problem of urban rainwater has become more and more prominent.The main manifestations are: severe rainwater runoff pollution; the risk of urban flood disasters increases; rainwater resources are lost in large quantities; the urban ecological environment is severely damaged.Many planning and design of urban drainage systems in my country only stays on how to directly dischar...
