Modular rotary sponge body device based on synchronous sewage interception and cleaning

Abstract

The invention discloses a modular rotary sponge body device based on synchronous sewage interception and cleaning. The device is characterized by consisting of a sewage interception system and a tubular cleaning system which are arranged on a driving mechanism, wherein the tubular cleaning system is sleeved in the sewage interception system, the tubular cleaning system is turned over by 90 degreesevery time by a driving mechanism, to form a rotary sponge body for synchronous sewage interception and cleaning, and the sewage interception system is a long and thin sponge body with a square section formed by a modular baffle, a flow guide net cover, a mixed filler and water-permeable geotextile. Compared with the prior art, the device has the advantages of simple structure, convenience in use, capability of effectively preventing filler blockage while realizing efficient interception of rainwater runoff, high stability, simplicity and convenience in maintenance, long service life and thelike, has a purification effect on rainwater runoff pollution, and effectively prevents the urban water body black and odorous problem caused by runoff pollution.

Description

technical field [0001] The invention relates to the technical field of sewage interception of urban rainwater runoff, in particular to a modular rotating sponge device based on synchronous sewage interception and cleaning. Background technique [0002] In the face of the two major challenges of rapid urbanization and extreme weather, our country is adopting a new strategy: turning the city into a huge "sponge". The construction of a "sponge city" that combines optimal utilization and ecological environment protection is receiving increasing attention. Sponge city is of great significance to systematically solve the problem of rain and flood disasters in urban development and the reduction of rainwater runoff pollutants. [0003] As the core component of the sponge city construction process, the sponge body plays an important role in the construction of the sponge city. Common sponges include rain gardens, grass planting ditches, green roofs, etc. Relevant studies have show...

Problems solved by technology

[0005] The object of the present invention is a modular rotating sponge device based on synchronous sewage interception and cleaning designed for the deficiencies of the prior art. The rotary sewage interception system and the tubular cleaning system of four independent purification units are used to form a synchronous The modular rotary sponge body for interception and cleaning, its rotary interception system rotates 90° every once in a while, so that the independent purification unit located above is always intercepting the sewage, and the purification unit located below is always cleaned by the tube type cleaning system , reciprocating in this way, the rotary sewage interception system can be used to realize the continuous batch interception of pollutants in the rainwater runoff, the pipe cleaning system can periodically clean the rotary sewage interception system, and the four purification units work in sequence, so that The whole device achieves continuous and synchronous interception and cleaning functions. Compared with conventional sponges, it has an efficient and long-lasting runoff pollution interception effect, has good anti-clogging performance and compatibility, and greatly improves the service life of sponges. The aspect ratio of the device is adjustable, and can be installed in parallel and in series according to the site conditions. The device is powered by solar energy, and the device rotates 90° intermittently at regular intervals, with low energy consumption, energy saving and environmental protection, and low construction cost. It is easy to maintain and is conducive to a large number of popularization and application. It has a purification effect on rainwater runoff pollution and effectively prevents the problem of black and odorous urban water bodies caused by runoff pollution.
