WASTEWATER PROCESSING SYSTEMS FOR POWER PLANT FLUE GAS DESULFURIZATION WATER AND OTHER INDUSTRIAL WASTEWATERS

摘要

Methods, systems, and/or apparatuses for treating wastewater produced at a thermoelectric power plant, other industrial plants, and/or other industrial sources are disclosed. The wastewater is directed through a wastewater concentrator including a direct contact adiabatic concentration system. A stream of hot feed gases is directed through the wastewater concentrator. The wastewater concentrator mixes the hot feed gases directly with the wastewater and evaporates water vapor from the wastewater. The wastewater concentrator separates the water vapor from remaining concentrated wastewater. A contained air-water interface liquid evaporator may be arranged to pre-process the wastewater before being treated by the wastewater concentrator.

1. A wastewater treatment system for a thermoelectric power plant, the system comprising:
a wastewater concentrator implementing a direct contact adiabatic wastewater concentrator system, the wastewater concentrator comprising a direct contact evaporative section and a gas-liquid separator; a stream of wastewater generated in a thermoelectric power plant operatively connected to the wastewater concentrator to supply the wastewater to the direct contact evaporative section; and a stream of hot feed gases operatively connected to the wastewater concentrator to supply feed gases to the direct contact evaporative section simultaneously as the stream of wastewater; wherein the direct contact evaporative section mixes the hot feed gases directly with the wastewater and evaporates water from the wastewater to form water vapor and concentrated wastewater, and wherein the gas-liquid separator separates the water vapor from the concentrated wastewater and exhausts discharge gases from the gas-liquid separator, including the water vapor and some or all of the feed gases.
