Rainwater settling pond for sponge cities

Abstract

The invention provides a rainwater settling pond for sponge cities. The rainwater settling pond comprises a clapboard A, a clapboard B, secondary strainers, a screw, a supporting plate, an impurity frame and a water treatment activated carbon tank, wherein an inner cavity of a settling pond body is divided into a settling chamber, a treatment chamber and a clean water chamber sequentially by the clapboard A and the clapboard B; a rotating handle penetrates the settling pond body at the top of the settling chamber and is connected with the screw; the supporting plate is connected to the screw through a threaded hole; the impurity frame is close to the clapboard A and placed at the bottom of the settling chamber; four groups of primary strainers are arranged on the side, close to the clapboard A, of the impurity frame; the movable water treatment activated carbon tank is mounted on a transverse plate. Rainwater can permeate the primary strainers and the secondary strainers and flow intothe treatment chamber, impurities are retained in the impurity frame, sludge on one side of the clapboard A can be removed through a conical structure when the impurity frame moves upwards, excellenteffect on rainwater purification is achieved under the action of the water treatment activated carbon tank, and applications of treated rainwater are expanded.

Description

technical field [0001] The invention belongs to the technical field of sponge cities, and more specifically relates to a rainwater sedimentation tank for sponge cities. Background technique [0002] At present, when rainwater is recycled and used, the rainwater will carry a large amount of dirt and impurities into the system. First, the rainwater needs to be sedimented so that the dirt and impurities can be precipitated in the sedimentation tank, and the purified water enters the system for recycling. [0003] The inventor found similar patents in the process of searching for patents. For example, the patent application number is: CN201621241581.9, which discloses an energy-saving and environmentally friendly rainwater sedimentation tank, including a tank body and a cover plate. A number of permeable holes, a settling chamber is set in the pool body, a guide block is set at the bottom of the settling cavity, and a first pressure-bearing bar, a second pressure-bearing bar and...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a rainwater sedimentation tank for sponge cities to solve the problem that impurities cannot be stored on the filter mechanism proposed in the above background technology, and the flow of rainwater is easily affected after the filter mechanism is blocked, and the rainwater is only in the filter mechanism. Under the treatment, it can only be used for general use, and the purpose is relatively single.
