Embodiment 1

[0038] Embodiment 1 rainwater harvesting system

[0039] Such as Figure 1-14 As shown, the rainwater collection system includes a rainwater collection box 1, a backwash box 2, a quartz sand filter 3, and a quartz sand filter 4. The rainwater collection box 1 is composed of an aeration fan accommodation chamber 101 and one or more storage The aeration fan 102 is arranged in the aeration fan accommodation chamber 101, and the aeration fan 102 communicates with the aeration pipe 105 in the water storage tank 104 through a plurality of ball valves 103. A plurality of aeration holes 106 are provided, and the bottom of the water storage tank 104 is provided with a plurality of grooves 107, and the side wall of the water storage tank 104 outside each groove 107 is respectively provided with a water storage tank mud outlet 108. The top of the water storage tank 104 on the opposite side of the water tank mud outlet 108 is provided with a water storage tank overflow port 109, and one ...

Embodiment 2

[0044] Embodiment 2 Rainwater collection system handles the method for rainwater

[0045] Such as Figure 1-14 Shown, the method for rainwater harvesting system processing rainwater comprises the following steps: rainwater is collected in the water storage tank 104 of the rainwater collection tank 1 by the rainwater collection pipeline on the roof of the factory area, and the collected rainwater is regularly exposed to the water storage tank 104 by the aeration fan 102 The aeration device in the water storage tank 104 adopts the form of microporous aeration to increase the amount of dissolved oxygen in the rainwater for subsequent treatment. When the liquid level control device in the water storage tank 104 detects that the liquid level reaches a higher level, The rainwater in the water storage tank 104 is referred to the quartz sand filter 3 and the quartz sand filter 4 through the water pump, and then through the filtration of the quartz sand and the adsorption and intercept...

Description

technical field [0001] The invention relates to the technical field of rainwater treatment, in particular to a rainwater collection system and a method for treating rainwater. Background technique [0002] The shortage of water resources has become an important factor that can not be ignored restricting the sustainable development of my country's economy. The uneven distribution of water resources in time and space in our country, coupled with the irrational exploitation and utilization of water resources and serious waste of human beings, as well as the aggravation of water pollution caused by industrialization, have made the contradiction of water use more and more prominent. my country is rich in rainwater resources, with an annual precipitation of 619 billion cubic meters. However, with the continuous development of urbanization, the impermeable area is increasing, and a large amount of rainwater runoff is directly discharged without treatment. Not only is there no compr...
