Embodiment Construction

[0023] The characteristics of rainwater are: irregular, irregular, and the margin is not controlled. The water quality of initial rainwater and the pollutants of later rainwater quality have changed. The initial rainwater mainly contains suspended matter brought by scouring, the SS content is between 20-400, and the pH is generally between 6-8. Turbidity is generally less than 30nt.

[0024] Therefore, suspended solids and sediment are the main pollutants of roof rainwater generated by substations, and the removal of suspended solids and sediment is the key to its treatment as reused water.

[0025] refer to Figure 1 to Figure 4 . A rainwater collection and utilization system of the present invention includes a water storage tank 2 arranged on the roof 1, a reaction tank 3, a sedimentation tank 4 and a filter tank 5 are also arranged on the roof 1, and the reaction tank 3 is provided with a water inlet 6. The water storage tank 2 is provided with a water outlet 7, the rea...

Abstract

The invention discloses a rainwater collecting and utilizing system and a rainwater collecting and utilizing method adopting the rainwater collecting and utilizing system. The rainwater collecting and utilizing system comprises a water storage pond arranged on a roof, a reaction pond, a settling pond and a filtering pond are also arranged on the roof, the reaction pond is provided with a water inlet, the water storage pond is provided with a water outlet, the reaction pond, the settling pond, the filtering pond and the water storage pond are sequentially communicated, a dosing device is arranged beside the reaction pond and comprises a tank body on which a stirring machine is installed, and the side surface of the tank body is connected with the reaction pond by a dosing pump. The rainwater collecting and utilizing system performs collection reaction, settling impurity removal, filtering impurity removal and storage on rainwater by using the reaction pond, the settling pond, the filtering pond and the water storage pond, and can effectively collect and utilize the rainwater so as to save water resources and reduce the running cost of transformer substations.

Description

technical field [0001] The invention relates to a rainwater collection and utilization system; the invention also relates to a rainwater collection and utilization method. Background technique [0002] With the development of social economy and the continuous increase of population, the shortage of water resources has become a very serious environmental problem faced by human society at present, and even the problem of human survival in the future. Water is the source of life and the basic condition for human survival. Only 3% of the fresh water resources on the earth are available for human use. For thousands of years, human beings have been making unremitting efforts to maximize the use of fresh water, and gradually realized that water resources are not inexhaustible, and the efficient use of fresh water resources has become a new trend. After the rainwater is collected, simple treatment can be carried out to meet the standard of reuse water. Compared with the high cost o...
