<div class="over_x"><P>贵溪化肥有限责任公司大力发展循环经济，努力构建资源节约型和环境友好型企业，企业“三废”综合利用年创产值达5000余万元。目前，贵化每年可“吃掉”47万吨磷石膏废渣，磷石膏废渣综合利用率超过75%，位居行业前茅。 </P>
<P>磷石膏废渣处理是化肥行业面临的普遍难题，“十一五”期间国内企业综合利用率平均仅为20%。贵化作为我省最大的化肥生产企业，每年要排放磷石膏废渣约60万吨，公司为保存废渣专门建设了面积达4500平方米的渣场，每年的废渣保存、处理成本达数十万元。近年来，贵化加大科技创新投入，投资1500万元建设了年产20万吨的磷石膏制水泥缓凝剂生产线。通过该生产线，废渣可变废为宝，成为水泥生产的原料，每年可为企业带来400多万元的经济效益。同时，该公司还联合地方政府招商引资，合作建设了年产2000万平方米纸面石膏板项目，每年可消耗磷石膏废渣27万吨，使磷石膏废渣利用率大大提高。</P></div>
