Embodiment 1

[0020] This embodiment provides a device for removing heavy metals from rainwater. The device includes: a wellbore buried on the ground surface, the main body of the wellbore is a cylindrical tubular structure, the side wall of the wellbore is provided with a water inlet, and the top of the wellbore is provided with a well cover bayonet; the filter well located at the lower part of the well shaft, the filter well is a cylindrical structure, the top is provided with a flared opening for receiving the well shaft, the bottom is a closed structure, and the side wall is provided with a water outlet; the filter element located in the filter well, The filter core is an interlayer filter screen with holes, and the filter screen is filled with adsorption materials. The adsorption material in the filter screen is composed of one or more of zeolite, bauxite, and activated carbon residue. It should be noted that the particle size of the adsorption material must be larger than the pore size...

Embodiment 2

[0025] This embodiment provides a rainwater heavy metal removal system, including several rainwater heavy metal removal devices as described in Embodiment 1, the system also includes a water storage tank, and the rainwater heavy metal removal devices are connected in series or in series or in parallel through pipelines, And finally connected to the water inlet of the storage tank through pipelines, the top of the wellbore is provided with a well cover, wherein the distribution and connection diagram of the rainwater heavy metal removal device in this embodiment is specifically arranged according to the actual situation of the construction site, figure 2 is only used to illustrate this embodiment intuitively.

Abstract

The invention discloses a rainwater heavy metal-removal device and system, and belongs to the field of municipal drainage. The device includes a wellbore buried in the earth surface, a filter well located at the lower part of the wellbore, and a filter core located in the filter well; a wellbore main body has a cylindrical tubular structure, the side wall of the wellbore is provided with a water inlet, and the top of the wellbore is provided with a well cover clamp port; the filter well has a cylindrical structure, and the top of the filter well is provided with an expanding port for bearing the wellbore, the bottom of the filter well has a sealed structure, and the side wall of the filter well is provided with a water outlet; the filter core is a sandwich filter screen with holes, and thefilter screen is internally filled with an adsorption material. The rainwater heavy metal-removal device and system can adsorb heavy metals in rainwater and centralizedly recycle the rainwater at thesame time, can be used in modern residential areas and also can be used in municipal pipeline networks in a large scale. The recycled rainwater can be used for greening water application and fire emergency in residential areas, and also can be used for urban water spraying and the like; the rainwater heavy metal-removal device and system are simple in overall structure and convenient in maintenance.

Description

technical field [0001] The invention relates to a rainwater heavy metal removal device and system, belonging to the field of municipal drainage equipment, in particular to a sewer well capable of absorbing heavy metals and a system composed thereof. Background technique [0002] At present, the rainwater drainage pipe network in ordinary residential areas is all underground pipe network, and the sewer well is usually made of bricks, its structure is simple, and the rainwater is directly discharged into the municipal sewage pipe network through the sewer pipe network without any treatment, not only Rainwater cannot be used rationally, and at the same time, it will increase the pressure on municipal sewage treatment. At present, water resources are becoming more and more scarce. How to effectively use rainwater and realize the separation and independence of rainwater pipe network and municipal sewage pipe network is worth thinking about. Contents of the invention [0003] I...
