利用废白土的重金属污染盐碱地改良剂及盐碱地改良方法
摘要：
本发明提供了一种利用废白土的重金属污染盐碱地改良剂和改良方法，改良剂的原料配方包括废白土70‑80％、复合微生物菌剂0.5‑2％、水泥3‑10％、木质素酸钙3‑5％、酒石酸2‑4％、草木灰9％‑13.5％，所述的复合微生物菌剂为枯草芽孢杆菌、地衣芽孢杆菌、侧孢芽孢杆菌、泾阳链霉菌、胶冻样芽孢杆菌按培养液体积比为1:1.2‑1.6:0.5‑0.7:1.2‑1.5:0.6‑0.9组成的混合物。采用本发明改良剂并结合本发明改良方法能够有效实现盐碱地特别是重金属污染盐碱地的改良，从根本上解决盐碱地的治理要求，同时本发明成本低，可实现资源再利用，降低环境污染。
摘要（英）：

The invention provides a heavy metal-polluted saline land modifier by using waste white clay and a saline land improvement method. The modifier comprises the following raw materials: 70-80% of waste white clay, 0.5-2% of composite microbe inocula, 3-10% of cement, 3-5% of lignin acid calcium, 2-4% of tartrate, and 9-13.5% of plant ash; and the composite microbe inocula is a mixture of bacillus subtilis, bacillus licheniformis, bacillus laterosporus, streptomyces jingyangensis and bacillus mucilaginosus according to volume ratio of a nutrient solution at 1: 1.2-1.6: 0.5-0.7: 1.2-1.5: 0.6-0.9. The modifier and an improvement method can effectively realize the improvement of the saline land, especially the heavy metal-polluted saline land, treatment requirement of the saline land can be radically solved, the cost is low, re-utilization of the resource is realized, and the environment pollution is reduced.
