The invention relates to a thermal power
plant water supply and drainage management method and
system based on three-dimensional display, wherein the
system comprises a production water tank, a rainwater recycling unit, a domestic water unit, a chemical
water treatment unit, an auxiliary
machine cooling unit, a main
machine cooling unit, a comprehensive utilization unit, a unit, a domestic sewagepool, an
industrial wastewater treatment unit, a service water tank, a desulfurization unit and a desulfurization
wastewater zero
discharge element. The management method comprises the following stepsof (1) establishing a three-dimensional display model of a power
plant water supply and
drainage network system; (2) acquiring
relevant information points, and extracting all relevant data of the instantaneous optimal value; (3) running the three-dimensional display model, and displaying a network three-dimensional diagram and a
water balance test
block diagram; (4) carrying out online monitoringon the
water balance state of the
water supply and
drainage network system; (5) analyzing over-standard data, performing automatic running and adjusting, and giving out an early warning when the system is abnormal; and (6) solving the problems based on an
expert consultation and diagnosis technology. According to the method, visual grading management is carried out on the
water resources of the thermal power
plant,
zero emission of the
wastewater is realized, the production cost is lowered, and the
natural environment is protected.
