1) pre-sedimentation
预沉
1.
The coagulation/sedimentation efficiency of the first flush without pre-sedimentation is obviously better than that with pre-sedimentation.
结果表明,最佳混凝剂为聚合氯化铝(PAC),其最佳投量为20～35 mg/L;混凝/沉淀工艺对初期雨水的浊度、COD的去除率较高,均可达90%以上;不预沉的初期雨水径流的混凝/沉淀效果明显优于预沉后的;综合考虑初期雨水弃流装置的建设、运行、维护、管理等因素,建议校园或类似区域宜选择初期雨水不弃流,将收集到的全部雨水经混凝/沉淀处理后再利用。
