Rainwater discarding system and control method

Abstract

The invention relates to a rainwater discarding system and a control method. The rainwater discarding system comprises a water quality online detector, a discarding controller, a discarding pool, a discharging device, a water quality discarding device and a water storage pool, wherein the water quality online detector is arranged in the discarding pool or on a water inlet pipeline which is connected with a rainwater collecting pipe, the discharging device and the water quality discarding device are respectively arranged on the discarding pool, the water storage pool is connected with the discarding pool through the water quality discarding device, and the discarding controller is used for controlling the opening and closing of the discharging device and the water quality discarding device according to the detection results of the water quality online detector. The rainwater discarding system has the advantages that the water quality of rainwater collected by a rainwater collecting network is detected by the water quality online detector, and the detection result is sent to the discarding controller; when the water quality does not meet the specified requirement, a discarding program is started; when the water quality meets the specified requirement, a water storage program is started. The rainwater discarding system has the advantages that the problems of clamping and blockage of the discarding system by the rainwater impurities are solved; the discarding is reliable, and the rainwater is furthest collected.

Description

technical field [0001] The invention relates to the field of rainwater utilization, in particular to a rainwater abandonment system and a control method. 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 i...

Problems solved by technology

, so that it can not only solve the problem of rainwater impurities blocking and blocking the abandoned flow system, solve the problem of linkage between the rainfall amount, rain quality and rain frequency of the rainwater abandoned flow, and solve the problem of safe diversion of rainwater when the rainstorm intensity exceeds the design intensity , and can achieve reliable flow abandonment, flexible adjustment and control can be performed in a timely manner according to the difference in rainfall frequency, rainfall, rainfall water quality, and the degree of pollution of the surrounding atmospheric environment to rainwater during rainfall, to achieve reliable flow abandonment, and at the same time to maximize collection rainwater, and make the design volume of the waste flow tank far smaller than the volume of the existing volumetric waste flow tank, thereby overcoming the shortcomings of the existing technology
