Based on this, the scheme of zero wastewater discharge system was proposed. One of the two key sectors in this scheme is the side-stream lime treatment process in the circulating water system, and the other is the desulfurization wastewater treatment which combines routine treatment with forward osmosis (FO), evaporation and crystallization. The scheme can achieve the comprehensive utilization of wastewater, sludge and crystallization salts at the same time, and therefore is valuable for the design of zero wastewater discharge system in coal-fired power plant.
