煤炭洗选工艺的环境污染煤炭洗选工艺的环境污染environmental pollution of coal cleaning technology 煤炭洗选工艺的环境污染(e nvironmentalpollution of eoal eleaning teehnology)煤炭洗选过程中形成大量废水和强烈的机械噪声，是煤炭洗选工艺的主要环境污染。 选谋废水煤炭采出之后须在洗煤机中使用大量清水进行洗选分级，各级煤炭脱水后作为产品煤外运，余下的是选煤废水，其中含大量煤泥。有关选煤废水的处理，中国统配煤矿选煤厂要求洗水完全闭路循环，并分为三个等级标准。一级，煤泥全部由厂内的脱水机械回收，实现洗水全部复用;二级，煤泥大部在厂内回收，小部分在厂外沉淀池回收，洗水全部复用;三级，煤泥在厂外煤泥池沉淀，清水大部分复用，余下的达标排放。并规定实现一级标准是企业升级的必备条件。 选煤废水闭路循环的处理工艺分为脱水机法和压滤机法两大类，其基本流程相同，都是将来自洗煤机的含有多量煤泥的高浊度选煤废水(经洗选分级的产品煤已取出)，在浓缩机内添加絮凝剂使煤泥絮凝沉淀，形成高浓的煤泥底流，然后分别进人不同的煤泥水终处理设备—脱水机或压滤机(两种工艺的区别主要在于各自的煤泥水终处理设备不同);煤泥在该处经历不同的工艺而脱水回收，上层清水则回流复用。 选煤噪声选煤噪声主要来自工艺设备的运转过程，如鼓风机、真空泵、局扇、过滤机等产生的空气动力性噪声;煤炭溜槽、振动筛、离心脱水机、胶带机、水泵、斗子提升机等运行形成的机械性噪声;电动机、电振给煤机、变压器等发出的电磁性噪声;其中有的设备运行时发出的实际是兼有数种特性的噪声。实际测定数据统枯结果表明，选煤厂噪声源的强度分布从蕊80dB(A)到>105dB(A)，其中占比例数最高的是_91一95dB(A)部分，约占全部噪声源的33.5纬。总体看来大致呈正态分布。由于选煤机械产生的噪声以中频和低频频谱为主，因而其衰减速度便较高频噪声为慢，所以传播距离更远，造成的污染影响也更严重。 (许征帆)
