生物法治理燃煤电厂高pH值灰坝水

Study on the Biological Treatment of High-Level pH Value Ash Water from Thermal Power Station

采用加丰、接种驯化的微生物产酸和种养水生生物等技术降低燃煤电厂灰坝水的pH值。该技术经过一年多实际运行考察，说明处理后灰坝水的pH值、SS和COD（Cr）等指标均符合GB8978－96《污水综合排放标准》的要求，并且可用于养殖和农灌。

Through the methods of adding some nutriment, inoculating and taming microorganism to produce acid, cultivating aquatic organisms, the pH of the ash-water discharge from thermal power station could be reduced. The pH, SS and COD(Cr) level of treated ash-water accorded with the demands of GB 8978-96 Integrated Wastewater Discharge Standard and the water was suitable to irrigation and cultivation.
