Rainwater flow abandoning system

Abstract

The invention discloses a rainwater abandonment system, which includes a rainwater confluence pipe, a side flow sampling pipe, a sewage pipe, a rainwater abandonment device, a rainwater collection pipe, a rainwater storage tank and a waste flow control box, wherein: the side flow sampling pipe and The rainwater confluence pipe is cross-connected, and its input end is equipped with a water quality analyzer, and the output end is connected to the sewage pipe; the rainwater abandonment device is provided with a water inlet, a water outlet and a sewage outlet, and the water inlet is connected to the output end of the rainwater confluence pipe. The water outlet is connected to the input end of the rainwater collection pipe, the sewage outlet is connected to the input end of the sewage pipe, and the output end of the sewage pipe is provided with a sewage valve; the liquid level gauge is installed in the rainwater storage tank and connected to the output end of the rainwater collection pipe ; The waste flow controller controls the opening and closing of the rainwater waste flow device and the blowdown valve according to the detection results of the water quality analyzer and the liquid level gauge. The invention solves the problem that the initial runoff rainwater and excess rainwater enter water storage equipment or structures, and avoids the potential safety hazards of confluence of rain and sewage and overflow of excess rainwater.

Description

technical field [0001] The invention relates to the field of rainwater utilization, in particular to a rainwater abandonment system. Background technique [0002] my country is a country with scarce fresh water resources, and water conservation has become a basic national policy of our country. With the advancement of science and technology, water conservation has gradually shifted from traditional water-quantity-based water-saving (such as water-saving appliances, etc.) to water-quality-based water-saving. The so-called water quality-based water saving is to change the traditional miscellaneous water source from municipal tap water to reclaimed water or rainwater, etc., to achieve cascaded water use. With the promotion and popularization of green buildings, rainwater utilization is getting more and more attention. [0003] Rainwater utilization includes rainwater harvesting, rainwater disposal, rainwater treatment, and storage and reuse. During the initial rainfall, the ...

Problems solved by technology

This will cause the phenomenon of rain and sewage confluence, and increase operating costs, investment costs and potential safety hazards

[0007] This shows that the above-mentioned existing rainwater abandonment flow device obviously still has inconvenience and defective, and urgently needs to be further improved
