Pollutant-into-river complex ecology closure system

Abstract

The invention discloses a pollutant-into-river complex ecology closure system, which is divided into three levels of interception devices. The first level of interception device is an auto-control interception device arranged at the tail end of a rainwater stand pipe; the second level of interception device is a catch pit arranged on a rain pipe; the third level of interception device is a regulation and storage pond arranged at the tail end of the rain pipe. A water treatment system comprises a roof first rain runoff roof treatment system, a wall first rain runoff wall treatment system and a ground runoff treatment system, and further comprises a domestic sewage treatment unit. After domestic sewage is discharged into the rainwater stand pipe, the domestic sewage is discharged into a sewage pipe network by being divided through the auto-control interception device; after the domestic sewage is discharged into the rain pipe, the domestic sewage is discharged into the sewage pipe network by being intercepted through the catch pit; after the domestic sewage enters the regulation and storage pond, the domestic sewage is discharged into the sewage pipe network through the regulation and storage pond. The system simultaneously solves the problem of pollution to a water body caused by direct discharge of the domestic sewage generated by refit of a balcony and a garage in a residential community into a river through the rain pipe, and the problem of water body pollution generated by direct discharge of more contaminative first rain into a river body.

Description

Technical field [0001] The invention relates to a river-pollution composite ecological interception system used for diversion system drainage, which is mainly used for intercepting domestic sewage generated by modification problems of residential balconies and / or underground garages and intercepting relatively polluted initial rainwater. Background technique [0002] In recent years, in order to improve the quality of urban water environment, many areas have implemented large-scale rain and sewage diversion projects to improve the control of pollution sources. In the communities that have achieved rain and sewage diversion, due to the early planning and construction of the community, the unreasonable building layout, and the living habits of residents, a considerable number of residents still transform their balconies into kitchens or laundry rooms and use the floor drain on the balcony. Sewage discharge (the role of the balcony floor drain is to discharge the rainwater entering ...

Problems solved by technology

[0005] Purpose of the invention: The technical problem to be solved by the present invention is to provide a river pollution composite ecological interception system for diversion system drainage, which can simultaneously solve the problem of domestic sewage generated by balcony and / or underground garages being directly discharged into the river body due to refitting The water pollution problem and the water pollution problem caused by the direct discharge of the heavily polluted initial rainwater into the river
