Abstract

The invention discloses an efficient rainwater filter and belongs to the technical field of rainwater treatment devices. The efficient rainwater filter comprises a filter communicated with a drain pipe, a collecting pipe with a water hole is coaxially arranged in the filter, and a central cylinder is coaxially arranged in the collecting pipe. The central cylinder is provided with an overflow hole, the bottom end of the central cylinder is communicated with the drain pipe, and a rainwater retention channel is formed between the collecting pipe and the central cylinder. Rainwater accumulated in the rainwater retention channel is discharged through the overflow hole in the central cylinder. The efficient rainwater filter is simple in structure and convenient to manufacture and use; in the whole filtering process, not only is full contact between the rainwater and a filtering medium guaranteed, but also pollutants in the rainwater can be effectively removed, and the filtering medium utilization rate and the treatment efficiency of the filter are also guaranteed.

Description

technical field [0001] The invention relates to a rainwater filter, which belongs to the technical field of rainwater treatment devices, in particular to a rainwater filter capable of improving the utilization rate of a filter medium and the treatment efficiency of the filter. Background technique [0002] As a result of urbanization, the impermeable area on the ground increases significantly, and pollutants accumulate on the ground. When it rains, the pollutants on the ground are washed away by the rainwater and enter the rainwater drainage system, and then enter the natural water body, causing water pollution. With the seriousness of urban air pollution and ground pollution, the pollution of rainwater runoff is becoming more and more serious. [0003] In the Chinese invention patent specification CN103638700A, a self-cleaning and maintenance-free clean rainwater runoff treatment device is disclosed. The device includes a container with a water distribution pipe and a water...
