【摘要】 对武汉市城市污水的水质化验分析得知 ,该污水的水质时变化幅度较大、有机污染物浓度较低且溶解性有机物所占的比例不高。该污水的处理方法宜从强化一级处理工艺、生物膜法和 BC法等几种工艺中优选 ,并应根据原水水质的变化逐时调整投药量或曝气强度 ,以便节省运行费用更多还原

【Abstract】 According to the chemical test of municipal wastewater in Wuhan, it has been shown that the contaminants in the wastewater greatly vary with time, the concentration of organic contaminants is very low, and the ratio of soluble organic materials is not high. The treating processes should be selected from Chemical Enhanced Primary Treatment (CEPT), fixed bio film processes and Biosynthesis/Chemical aided Flocculation (BC) process. And the doses of chemicals or the quantity of aeration should be changed with the variations of contaminants to save the operating cost.更多还原
