补充资料：排污费
排污费
排污费对排放污染物或超过规定污染物排放标准而排放的废水、废气、噪声及其他废弃物所征收的费用。 征收排污费的目的是在环境政策领域内，通过经济手段，给污染者增加经济负担，给污染治理者带来经济补贴.以促进治理和保护环境。国际经济合作与发展组织各成员国在其环境政策的早期阶段就已使用了经济手段.包括征收排污费、环境税、用户费、产品费、管理费等，最普遍的是征收排污费。世界各国都根据各自的国情，在不同范围和不同程度上开征了排污费。法国、瑞典等国家的排污费标准较高，主要为筹集资金，用于环境保护;而多数国家收费较低，远远不能达到污染治理所需费用，有些则是象征性收费。巾国企业事业单位向水体排放污染物的，按照国家规定缴纳排污费，超过国家或者地方的污染物排放标准的，按照国家规定缴纳超标排污费，并负责治理。实际上，中国实行的是以征收超标排污费为主，非超标排污费为辅的排污收费政策。中国的排污收费政策主要体现了:①缴纳排污费并不免除其应承担的治理污染、赔偿损害的责任。②对危害严重的污染物因子收费从严，对一般污染物因子收费从宽。
