Embodiment 1

[0048] Corresponding to Embodiment 1, this embodiment also provides a treatment method for surface runoff, such as Figure 4 As shown, the method includes:

[0049] S401, converging the surface runoff.

[0050] In this step, the surface runoff is collected by using a collection device. The collection device includes: curbs protecting the road surface on both sides of the river bank, and a water outlet is opened at the lower part of the curb, and the collected road rainwater is discharged into the primary water outlet through the water outlet. inside the filter.

[0051] S402. Perform primary filtering on the surface runoff.

[0052] In this step, the primary filter device is used to perform primary filtration on the surface runoff. The primary filter device is specifically a filter tank, and the filter tank is a square channel with a concrete structure. The filter tank includes: a first layer of gravel, a second layer of layer of gravel, the third layer of gravel; where,

Embodiment 3

[0065] In practical applications, when using the system provided in Embodiment 1 and the method provided in Embodiment 2 to process surface runoff, the specific implementation is as follows:

[0066] The system is arranged on both sides of a certain river in a certain city, such as figure 1 As shown, the system includes: a collection device 1, a primary filter device 2 and at least one secondary soil filter device 3; wherein,

[0067] The collection device 1 is used to confluence the surface runoff. The collection device 1 includes: curbs on both sides of the river bank to protect the road surface, and a water outlet is opened at the lower part of the curb, and the collected road rainwater is discharged into the water outlet through the water outlet. In the primary filtering device 2, primary filtering can be performed on the surface runoff.

[0068] The primary filtering device 2 is specifically a filter tank, the filter tank is a concrete structure square channel, and the f...

Abstract

The invention provides a system and method for treating surface runoff. The system comprises a collecting device, a primary filtering device and at least one secondary soil filtering device, wherein the collecting device is used for converging the surface runoff; the primary filtering device is used for carrying out primary filtering on the surface runoff; the at least one secondary soil filtering device are used for collecting primary-filtered surface runoff by using pipelines, carrying out secondary filtering on the surface runoff and draining secondary-filtered surface runoff into rivers. Thus, the treatment system can be arranged along river bank sides in a long distance manner and is used for carrying out multistage decontamination treatment on the surface runoff and then removing carrying contaminants such as suspended matters, COD, nitrogen and phosphorus from the surface runoff, and then, water is drained into the rivers, so that the rivers cannot be contaminated, the load of the sewage treatment system cannot be increased, and the drainage of municipal pipe networks cannot be affected; civic landscape plants can be planted on the at least one secondary soil filtering device so as to beautify environments.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a surface runoff treatment system and method. Background technique [0002] With the rapid development of society and economy, urban water safety and water environment problems are becoming more and more serious, and more and more cities are frequently experiencing environmental problems such as heavy rain, internal waterlogging, and black and smelly water bodies. For this reason, the state proposes the strategy of building a sponge city. Sponge city refers to strengthening urban planning and construction management, giving full play to the absorption, storage and slow release of rainwater by ecological systems such as buildings, roads, green spaces, and water systems, effectively controlling rainwater runoff, and realizing natural accumulation, natural infiltration, and natural purification. A way of urban development. [0003] Rainwater is an impo...
