氮肥生产废水用于锅炉冲灰渣和烟道除尘

Use of Wastewater from Nitrogen Fertilizer Production for Coal Ash Rinsing from Boiler and Dust Removal from Flue

湘江氮肥厂以生产排水作为热电厂锅炉的冲灰渣和烟道除尘器用水,工程投运后可节约自来水720×104m3/a,减少水费和排污费120万元/a,且废水中的COD、NH3-N、CN-、S2-以及烟道气中的SO2得以有效去除。

The production wastewater from Xiangjiang Nitrogen Fertilizer Plant was used for rinsing coal ash from boiler and removing dust from fuel in thermal power plant.After the project was put into operation,tap water was saved by 720×10~4 m^3/a,and water tariff and wastewater drainage fee were reduced by 1.20 million yuan/a.COD,NH_3-N,CN^-,and S^(2-)can be removed from wastewater,and SO_2 removed from fuel gas.
