Modular micro-ecological filter bed type green roof and water and mud discharging method

Abstract

The invention discloses a modular micro-ecological filter bed type green roof and a water and sludge discharging method. The modular micro-ecological filter bed type green roof comprises water storagetank bodies, micro-ecological filter beds, water collecting tanks and main tanks, a plurality of water storage tanks are adjacently arranged front and back to form a plurality of rows of array modules, two sides of each water storage tank body communicate with the water collecting tanks, and the water collecting tanks communicate with one another and communicate with the main tanks in two sides of the array modules. The micro-ecological filter beds are arranged in the water storage tank bodies, an ecological medium layer in each micro-ecological filter bed is suspended in a water body of thewater storage tank body, and mud generated in the micro-ecological filter beds is deposited at the bottoms of the water storage tank bodies and is discharged and gathered in the water collecting tanks; and water treated by the micro-ecological filter beds is discharged into the water collecting tanks, gathered to the main tanks and then discharged. By arranging the modular micro-ecological filterbeds, the problems of blockage and service life of water storage and green roofs are solved, and the green plant irrigation, maintenance and purification functions in rainy areas or water-deficient areas are achieved.

Description

technical field [0001] The invention belongs to the technical field of urban construction and environmental protection, and in particular relates to a modular micro-ecological filter bed type green roof integrating purification and water storage. The roof has self-regeneration capability, and is especially suitable for the drier areas in northern my country and old urban areas sponge city construction. Background technique [0002] As one of the important contents of sponge city and green building, green roof has played an important role in reducing storm peaks, slowing down urban flooding, increasing urban green area, alleviating urban heat island, improving air quality, and sound insulation and noise reduction. Therefore, aiming at the shortcomings of the traditional green roof covered with soil on site, the improvement of green roof or the development of new green roof has become a research hotspot. Judging from the published Chinese patents, the research and development ...
