利用电厂粉煤灰输送与处置系统处理制浆造纸污水的研究

制浆造纸污水和电厂粉煤灰混合流体的静态与动态模拟沉降实验证实，其固液分离性能好，粉煤灰对污水中COD、酚、色度等污染物有去除作用。吸附渗透实验估算了粉煤灰、亚粘土对COD、酚的吸附量，取得了地下水影响预测参数。

Study on Treatment of Paper Mill Wastewater with Fly ash Transport and Disposal System

Abstract By the settlement tests , the better solid liquid separation characteristic of the mixed fluid of the coal ash-wastewater , removal action of the coal ash on COD , phenol and color index , is confirmed . By the adsorption and permeation tests , the adsorption capacities of coal ash and mild clay to COD , phenol are evaluated , and some parameters for the prediction of impact on groundwater are obtained . The quality of the efflunce on the ash disposal area is predicted . The study results show : The treating process of pulp and paper making wastewater by use of coal ash transporting and disposing system , has saving water , reducing pollutant discharge , and is lower investment and cost of operation , it may be used to local conditions .
