Document Type and Number:
WIPO Patent Application WO/2019/061870
Kind Code:
A1
Abstract:
A water drainage system and a water drainage control method. The water drainage system has the effect of intelligent water drainage. A control system rationally controls the degree to which a hydraulic switch in the water drainage system is open and related assemblies to realize rational water drainage, and dirty water or initial rainwater is stopped from flowing into a sewage treatment plant to the maximum extent while flood safety is guaranteed. The water drainage control method comprises a water level method, a water quality method, a water quality-water level method, a time method, a total amount method, a rainfall method, a time-water level method, a total amount-water level method, and a rainfall-water level method. The control by the method effectively eliminates the phenomena in the prior art that a pollutant stopping pipe cannot perform flow limiting, and clean water or later rainwater can also enter the pollutant stopping pipe to be conveyed to a sewage treatment plant. By rationally controlling drainage approaches of dirty water, initial rainwater and middle and later rainwater, the dirty water and initial rainwater are stopped from flowing into a sewage treatment plant to the maximum extent, and clean water is drained to natural water.
