Greening circulating system based on plant cultivation on building outer wall and wastewater utilization

Abstract

The invention relates to a greening circulating system based on plant cultivation on a building outer wall and wastewater utilization. The system is characterized in that the contact position of a rainwater pipe and the edge of each layer of water storage tank is provided with a water outlet; a fixed steel rack is fixed on the building outer wall above the horizontal line where each layer of window frame is located, a three-dimensional net is laid in the fixed steel rack, a soil-simulated sponge substrate layer mixed with seeds is arranged on the three-dimensional net through pouring, a metalmesh fixed to the fixed steel rack is arranged outside the soil-simulated sponge substrate layer, the water storage tank is fixed on the building outer wall below the horizontal line where each layerof window frame is located, the interior of the water storage tank is separated into two areas through a water-permeable filter plate, the area on one side is the water inlet area of a domestic wastewater inlet pipe, the bottom surface of the area on the other side is provided with at least two overflow pipes, the lower ends of the overflow pipes are directly communicated to the plant cultivationmechanism of the next lower layer, and the area on the other side is filled with the soil-simulated sponge substrate. The system has the advantages that plants on the building outer wall and domesticwastewater utilization are combined, and the system is ecological, environmentally friendly, energy-saving and economical.

Description

technical field [0001] The invention relates to the field of greening of building exterior walls, in particular to a greening circulation system based on plant cultivation and waste water utilization on building exterior walls. Background technique [0002] In today's society, urban land resources are becoming more and more scarce, high-rise buildings are increasing and buildings are densely distributed, resulting in less and less urban green area and deteriorating ecological environment. How to increase green quantity and green capacity, improve the green level of the whole city, and embody the connotation of green buildings are common issues faced by urban garden construction. Traditional planting substrates, such as nutrient soil, peat soil, coconut bran, etc., are often used in the process of exterior walls and building greening, which often have excessive load-bearing, powder falling, seepage, odor, settlement, hardening, soil erosion, and easy Insect pests, poor venti...
