Problems solved by technology

[0005] The above treatment methods have been widely used in actual runoff pollution control, but there are still some deficiencies and defects in the application, such as: the treatment efficiency of water retention ponds is relatively low, the purification cycle is relatively long, and mosquitoes and flies can also breed , there are potential environmental sanitation problems; and although the efficiency of the rainwater regulation pond is relatively high, the cost of infrastructure and operation is relatively high, and there is a certain degree of difficulty in operation and maintenance

Embodiment Construction

[0023] The invention is a novel urban surface runoff ecological treatment method: the urban surface runoff ecological treatment method mainly includes components such as a runoff interception device, a pond storage and purification system, and an artificial wetland treatment system. The runoff interception device is installed near the end of the urban drainage pipe network, usually close to the straight outlet of the rainwater pipe, and is composed of a drainage pipe culvert and a diversion pipe culvert. The wetland is built on the shore zone of the surface water body according to the nearby topography. When it rains, the rainwater runoff flows into the urban stormwater pipe through the storm water outlet. At this time, the runoff interception device is activated, and the initial runoff is intercepted and diverted to the pond system through the interception device. The pond system has the function of storage and settlement and preliminary purification. In this way, the suspende...

Abstract

The invention discloses an urban surface radial flow ecological disposing method, which is characterized by the following: intercepting primary radial flow of urban rain less than 15mm in the disposing system within pond system and artificial marshland; sedimenting; purifying; draining flow in the natural water.

Description

technical field [0001] The invention relates to an ecological control technology for urban non-point source pollution, in particular to a novel ecological treatment method for urban surface runoff. Background technique [0002] Urban surface runoff pollution refers to the accumulation of a series of pollutants (such as crude oil, N, P, toxic substances, etc.) , organic matter, etc.), and then enter the water body, polluting surface water or groundwater. Urban surface runoff is a typical non-point source pollution, which has the characteristics of wide geographical range, strong randomness, and complex causes. Non-point source pollution has become an important factor of water environment pollution. The control and treatment methods of urban surface runoff are mainly divided into source control and sink treatment. Among them, source control can effectively reduce runoff flow and runoff pollution load, while sink treatment can effectively control runoff pollution at the end to...
