Abstract

The invention relates to a municipal early-stage rainwater pollutant spiral-type in-situ purification device. The device comprises an overflow distribution well communicating with a conventional gully. A small rainwater retention chamber is arranged at each of the two sides of the overflow distribution well. Through water pipes, the overflow distribution well communicates with the small rainwater retention chambers. An adjustable overflow weir is provided inn the overflow distribution well. Suspended biological filler balls are placed in the small rainwater retention chambers. The inner wall of the overflow distribution well has a spiral body shape. The small rainwater retention chambers are divided into 6 layers, and have maze intestinal shapes. The upper parts of the small rainwater retention chambers are designed into curved pipes surrounding the overflow distribution well. The device provided by the invention has the advantages that: during a rain early-stage, particle organics can be effectively retained, such that input amount of early-stage rainwater pollutant to rivers can be reduced. With the device, more than 75% of particle organics in early-stage rainwater can be removed and bio-degraded. The device is suitable to be used for controlling municipal early-stage rainwater pollution, and for reducing the pollution degree of the early-stage rainwater to water quality and ecological environment.

Description

technical field [0001] The invention relates to a treatment device for runoff rainwater on the ground of cities and factories, in particular to a spiral in-situ purification device for municipal initial rainwater pollutants. Background technique [0002] Application number 200910264168.2 discloses an in-situ reduction device for urban landscape river initial rainwater pollutants, which is characterized in that the conventional rainwater outlet is connected to the overflow distribution well, and the overflow distribution well is connected to the rainwater detention chamber through the water pipe, and the overflow distribution well is adjustable. The overflow weir and the suspended biological filler balls are placed inside the rainwater retention chamber. The overflow well in this device is a straight structure, which is not conducive to the precipitation of solid inorganic dirt, especially the precipitation of inorganic sand particles with a small specific gravity. The rainwa...
