Description

Rainwater recycling device Technical Field The utility model belongs to the technical field of rainwater collection and treatment, and particularly relates to a rainwater recycling device. Background The rainwater rapidly flows off during rainfall, waterlogging disasters are easy to cause, and the rainwater flows off can carry pollutants to cause surface and water pollution. However, the existing rainwater treatment process is not mature enough, the arrangement of the whole rainwater treatment and recycling processes is relatively dispersed, the rainwater collection and treatment efficiency is low, the treatment effect is unstable, and the daily management and maintenance are inconvenient. The invention CN111691526A discloses a rainwater treatment and recycling system, which comprises a safety diversion well, a rainwater drainage well, an underground purification integrated machine and a rainwater reservoir, wherein the rainwater drainage well is internally provided with a rainwater drainage device, one end of the rainwater drainage well is connected with a rainwater collecting pipe of the safety diversion well, the other end of the rainwater drainage well is connected with a collecting pipeline, the collecting pipeline is connected to a connecting pipe at the upper part of one side of the underground purification integrated machine, the connecting pipe at the lower part of the other side of the underground purification integrated machine is connected to the rainwater reservoir, a PP water storage module is arranged in the middle of the rainwater reservoir, and a sludge pump and a recycling pump are respectively arranged in the rainwater reservoirs at two sides of the PP water storage module.
