Self-cleaning maintenance-free clean rainfall runoff treating device

Abstract

The invention discloses a self-cleaning maintenance-free clean rainfall runoff treating device. The device comprises a container with a distribution pipe and a water outlet pipe, wherein the distribution pipe is arranged on the lower part of the container; the water outlet pipe is arranged on the upper part of the container and is connected with a follow-up system, the upper part of the container is provided with a feeding hole which is utilized as a window, the container is filled with a light padding filtering medium of a light padding, detachable perforated plates are arranged on the upper part of the light padding and are arranged below the water outlet pipe, and the lower part of the light padding is provided with a perforated plate; the distribution pipe is positioned below the perforated plate; the bottom of the container is provided with a drain pipe, and the drain pipe is provided with an electronic control switch and can control drain through the electronic control switch. The self-cleaning maintenance-free clean rainfall runoff treating device provided by the invention has the advantages that main pollutants in clean rainfall runoff are effectively removed, meanwhile, the automatic backwash is realized, energy is saved, a problem that conventional equipment needs to be maintained by a special person is solved, the use is convenient, water is saved, and meanwhile, the impacting problem to a municipal pipe caused by the runoff is also cut down.

Description

technical field [0001] The invention relates to a rainwater runoff treatment device. Background technique [0002] Waterlogging occurs in most cities in my country during the rainy season, especially in the rainy south. With the acceleration of urbanization, a large number of hard ground and building roofs have replaced natural ground with permeable capacity, causing rainwater to be discharged into the pipe network through runoff, which has impacted the pipe network and caused a large number of waterlogging. If the transformation of the pipe network is undoubtedly a long-term complex project with huge investment, it is difficult to have obvious results in the short term. However, if part of the rainwater runoff is collected and utilized, it can not only reduce the impact of rainwater runoff on the pipe network, greatly relieve the drainage pressure, improve the urban waterlogging situation, but also save water. At present, the key to restricting the use of rainwater is tha...
