Abstract

The invention discloses an initial rainwater split-flow device. A water collector of the initial rainwater split-flow device divides an inner cavity of a split-flow device body into a diversion cavityand a split-flow cavity. A detachable basket grid is installed in the diversion cavity. A water inlet, a water outlet and a split-flow opening are formed in the split-flow device body. The water outlet is communicated with an urban rainwater pipeline network. The split-flow opening is communicated with the split-flow cavity and an urban sewage pipeline network separately. A flow locking mechanismis arranged between the diversion cavity and the split-flow cavity and includes an upper float ball and a lower float ball. The upper float ball is located in the diversion cavity, and the lower float ball is located in the split-flow cavity. The split-flow device is simple in structure, long in service life and good in security and stability. The split-flow initial rainwater of the initial rainwater split-flow device is simple and efficient in the process and does not need a power source, therefore, energy is conserved, and the environment is protected. The initial rainwater processed by thesplit-flow device is discharged into the urban sewage pipeline network while relatively clean rainwater is discharged in the urban rainwater pipeline network, so that the follow-up processing pressure on rainwater collected by the rainwater pipeline network can be effectively reduced, and safe and reliable recycle of the rainwater is ensured.

Description

technical field [0001] The invention relates to a rainwater treatment device, in particular to an initial rainwater abandonment device. Background technique [0002] With the rapid development of urbanization in my country, the water consumption has increased sharply, and the shortage of water resources has become increasingly serious. In order to meet the needs of sustainable urban development, the reuse of rainwater resources has been widely valued. [0003] Initial rainwater, that is, rainwater at the beginning of rainfall. Generally, it refers to the precipitation that has formed surface runoff with a thickness of 10-15mm on the ground. In the early stage of rainfall, the rainwater dissolved a large amount of polluting gases and pollutants in the air, such as acid gas, automobile exhaust, industrial waste gas, PM2.5, etc. Therefore, the initial rainwater contains a large amount of pollutants, and the pollution level is relatively high, even exceeding the pollution leve...
