据统计,化肥行业的“三废”排放量占化工行业排放总量的一半左右。在国务院2000年污染源必须达标排放的情况下,化肥企业面临生存问题。为此,有关部门确立了化肥生产实施清洁生产的具体方向:采用清洁的原料。目前新疆、四川、海南、陕甘宁都有发展大化肥的天然气资源,特别是“西气东输”工程将为化肥工业提供清洁原料,以解决以煤为主要原料生产化肥造成的严重污染问题。加大生产规模。组建一批大型化肥集团,建设100万t以上的磷复肥生产基地、100万t以上的尿素生产基地,改造一批小氮肥、小磷肥企业,使这些企业在规模水平、清洁生产技术和装备水平上都上一个新台阶。同时,发展大颗粒尿素、包衣氮磷肥,提高化肥的利用率,减少化肥生产过程和使用过程的污染。
According to statistics, the “three wastes” emissions of the fertilizer industry account for about half of the total chemical industry emissions. In the State Council, pollution sources must meet discharge standards in 2000, chemical fertilizer companies face the issue of survival. To this end, the relevant departments established the specific direction for the production of cleaners to implement cleaner production: using clean raw materials. At present, Xinjiang, Sichuan, Hainan, and Shaanxi, Gansu, and Ningxia all have natural gas resources for the development of large chemical fertilizers. In particular, the “West-East Gas Pipeline Project” will provide clean raw materials for the fertilizer industry to solve the serious pollution caused by the production of chemical fertilizers using coal as the main raw material. problem. Increase production scale. Set up a batch of large-scale fertilizer group, build more than one million tons of phosphate compound fertilizer production base, more than one million tons of urea production base, transform a batch of small nitrogen fertilizer, small phosphate fertilizer companies, make these companies in scale, clean production technology and equipment A new level has been reached on the level. At the same time, the development of large-particle urea, coating of nitrogen and phosphate fertilizers will increase the utilization rate of chemical fertilizers, and reduce the pollution of the fertilizer production process and use process.
