据统计数字显示,我国染整废水年排放超过18亿吨,占纺织全行业的80%。染整行业年新鲜水取水量约21亿吨,年耗能超过2300万吨标准煤。是产生环境污染、耗用水资源和能耗明显的一种工业。随着国家政策强制性要求,从2010年起实施的《印染行业准入条件》无疑抬高了印染企业的准入门槛。2011年,国家把印染行业列入排污治理的重点行业之一。节能(特别是节水)、降耗、环保是人类社会生存面临的三大课题,引起了全人类的高度重视。
According to statistics, the annual discharge of dyeing and finishing wastewater in China exceeds 1.8 billion tons, accounting for 80% of the textile industry. Dyeing and finishing industry, fresh water intake of about 2.1 billion tons, the annual energy consumption of more than 23 million tons of standard coal. Is to produce environmental pollution, water consumption and significant energy consumption of an industry. With the mandatory requirements of national policy, since 2010, “printing and dyeing industry access conditions” undoubtedly raised the threshold for printing and dyeing enterprises access. In 2011, the state included the printing and dyeing industry as one of the key industries for sewage treatment. Energy conservation (especially water conservation), consumption reduction and environmental protection are the three major issues facing the survival of human society and have aroused the great attention of all mankind.
