Problems solved by technology
Because this type of rainwater treatment device treats all the incoming rainwater, the rainwater treatment load is large, and the rainwater treatment effect is poor; in addition, the rainwater is treated first and then stored for use, and the water quality will deteriorate, which is unfavorable to the ecological environment. Impact
At present, there is no relevant report on the time-delayed rainwater treatment device

The invention relates to a rainwater off-line device, which comprises an off-line isolation pond, a water inlet pipe, a light floating block, a floating block guide rail, a water sealing valve, a drainage siphon and a sleeve, wherein the water inlet pipe connected with a reservoir at front end is arranged on the side wall at the bottom of the off-line isolation pond, the floating block guide rail and drainage siphon are arranged in the off-line isolation pond, the water sealing valve is arranged below the water inlet of the drainage siphon, the light floating block can float on the water surface at the top of the floating block guide rail, the sleeve connected with the light floating block sleeves on the floating block guide rail, the lower end of the sleeve is provided with a support rod connected with the water sealing valve, and the water outlet of the drainage siphon is located on the side wall at the bottom of the off-line isolation pond opposite to the water inlet pipe, and outwards communicated with a rainwater treating pond. The rainwater off-line device has the advantages that, delay treatment of the rainwater is achieved, and load of the rainwater treatment device is reduced.
Description
technical field [0001] The invention belongs to the technical field of rainwater treatment, and in particular relates to a rainwater off-line device. Background technique [0002] In recent years, due to the development of urbanization, there are more and more hardened roads and roofs in cities. When heavy rainfall occurs, the rainwater will wash away the roads and roofs, resulting in a higher concentration of pollutants in the initial runoff. Direct discharge into water bodies will cause serious impact on water bodies. [0003] The rainwater treatment device has an online treatment device and an offline treatment device. The investment cost of the online treatment device is relatively high, and the treatment water quality is average; the offline treatment device has the advantages of making the rainwater sandy and the treatment water quality is relatively good. But these rainwater treatment devices are instant treatment devices, that is, when rainwater strikes, after rainw...
