Comprehensive utilization system and comprehensive utilization method for transformer substation rainwater

Abstract

The invention discloses a comprehensive utilization system for transformer substation rainwater and a method. The system comprises a roof runoff of a transformer substation, an oil pool runoff, a grating, an abandoning flow, a drainage network, a firefighting reservoir, a first water pump, a firefighting water point, an accident oil pool, a second water pump, a processing device, a domestic water point, a rainwater and sewage recycling device, domestic sewage, a septic tank, a reclaimed water point and a third water pump; the grating is used for intercepting the impurities in the roof runoff and the oil pool runoff; the grating is respectively connected with the drainage network, the firefighting reservoir and an accident oil pool; the firefighting reservoir is connected with the firefighting water point; the accident oil pool is connected with a water inlet of the processing device; the processing device is connected with the domestic water point through a pipeline; the accident oil pool is connected with the water inlet of the sewage recycling device; a water outlet of the septic tank is also connected with the water inlet of the sewage recycling device; the sewage recycling device is connected with the reclaimed water point. The comprehensive utilization system disclosed by the invention not only can be used for solving the problem of water supply of the transformer substation, but also can realize zero sewage emission, zero rainwater emission or local emission of transformer substation.

Description

technical field [0001] The invention belongs to the technical field of substations, and relates to a rainwater comprehensive utilization system and method, in particular to a substation rainwater comprehensive utilization system and method. Background technique [0002] With the continuous acceleration of my country's industrialization process, the demand for electricity is increasing day by day, followed by the planning and construction of more substations. Since there is no municipal water supply network near most substations, and the geology of the site does not meet the conditions for drilling wells, the daily operation of substations often faces the embarrassing situation of no water available. At the same time, substation rainwater is often faced with no way to drain due to the limited location of the station site and surrounding drainage conditions. [0003] Substations in the prior art often purchase water from other places to solve the problem of substation water u...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a system and method for comprehensive utilization of substation rainwater, which collects substation rainwater and uses it as substation domestic water, reclaimed water, and fire-fighting water sources after corresponding process treatment, not only It can solve the problem of substation water supply and water source, and can also realize zero discharge of substation sewage, zero or partial discharge of rainwater
