A method for collecting and purifying rainwater around buildings

Abstract

The invention discloses a method for collecting and purifying rainwater around a building, which comprises the following steps: step 1, collecting roof rainwater, surface rainwater, and underground rainwater into a rainwater collection pool; step 2, sucking the rainwater in the rainwater collection pool through the mouth of an absorption bell , and then sent to the sand filter tank through the rainwater reuse pressurized pump, the coagulation dosing device puts the coagulant into the sand filter tank and mixes with the rainwater, and the water from the sand filter tank enters the microporous filter and the ultrafiltration filter in turn, and the ultrafiltration The clean water end of the filter is connected to the rainwater reuse clean water tank, and the rain water reuse clean water tank is connected to the backwash end of the ultrafiltration filter through the backwash pump; step 3, the water in the clean water tank is transported to the water feature pool, presenting a static water feature. The present invention can improve the humidity and microclimate of soil and air around the building for the purification, storage and on-site utilization of rainwater, reduce the urban heat island effect, create a comfortable office environment, implement relevant landscape measures for rainwater utilization, and make the landscape type of residential areas And the spatial level is more abundant.

Description

technical field [0001] The invention belongs to the technical field of rainwater collection and purification, and in particular relates to a rainwater collection and purification method around buildings. Background technique [0002] Today, the voice of the harmony between man and nature is getting louder and louder. Water plays an important intermediary role in the building space. It can form a poetic and human space by combining with other elements. Water can create an environment that affects people's emotions. Static water not only has the effect of mirror reflection, but also purifies the environment, plans space, expands space, and enriches the color and atmosphere of the environment. [0003] The characteristic waterscape design fully integrates the concepts of traditional Chinese geomantic feng shui, "Holding the wind and gathering Qi, getting water first" and "using water to generate wealth and carrying all things", and the Western minimalist mirror waterscape.

[0004] Large-scale buildings and the hard pavement outside the building cover the original natural soil layer. The use of some stainless steel paving materials replaces the natural soil surface. If appropriate measures are not taken, it will prevent the natural infiltration of rainwater and affect the surface. The transformation of water into groundwater will lead to the loss of rainwater resources, which will violate the design principles of green ecology and the value concept of sustainable development

At the same time, a large amount of water is consumed for garage washing, greening irrigation, road sprinkling, and waterscape replenishment of buildings. If tap water is used, it will not only cost a lot of operating costs, but also cause a lot of waste of drinking water resources.
