摘要
分析了微污染水的水质特点,在现有的微污染水处理技术的基础上,提出了一种新的预处理方法,即采用活性污泥法对微污染水进行预处理。实验结果表明:采用活性污泥法处理微污染水,处理效果好,高锰酸钾指数CODmn和总有机碳TOC的平均去除率分别为90.82%和87.09%,最终出水CODmn和TOC平均值为2.644mg/L和2.993mg/L,去除效果明显。
Based on the analysis of the water quality characteristics of micro-polluted water and the existing micro-polluted water treatment technology,a new pre-treatment method was proposed,which used the activated sludge method to pre-treat the micro-polluted water.The experimental results show that the treatment of micro-polluted water by activated sludge method has good treatment effect.The average removal rates of potassium permanganate index CODmn and total organic carbon TOC are 90.82%and 87.09%,respectively.The final effluent CODmn and TOC average is 2.644 mg/L and 2.993mg/L.The removal effect is obvious.
